genes expression analyses of sea-island cotton (gossypium barbadense l.) during fiber development.	sea-island cotton (gossypium barbadense l.) is one of the most valuable cotton species due to its silkiness, luster, long staples, and high strength, but its fiber development mechanism has not been surveyed comprehensively. we constructed a normalized fiber cdna library (from -2 to 25 dpa) of g. barbadense cv. pima 3-79 (the genetic standard line) by saturation hybridization with genomic dna. we screened pima 3-79 fiber rna from five developmental stages using a cdna array including 9,126 plasm ...	2007	17377794
effect of exogenous ecdysteroids on growth, development, and fertility of the egyptian cotton leafworm spodoptera littoralis boisd. (lepidoptera: noctuidae).		2016	17425056
construction and characterization of the first bacterial artificial chromosome library for the cotton species gossypium barbadense l.	as the second most widely cultivated cotton, gossypium barbadense is well known for its superior fiber properties and its high levels of resistance to fusarium and verticillium wilts. to enhance our ability to exploit these properties in breeding programs, we constructed the first bacterial artificial chromosome (bac) library for this species. the library contains 167 424 clones (49 920 bamhi and 117 504 hindiii clones), with an estimated average insert size of 130 kb. about 94.0% of the clones ...	2006	17426754
a potato carboxypeptidase inhibitor gene provides pathogen resistance in transgenic rice.	a defensive role against insect attack has been traditionally attributed to plant protease inhibitors. here, evidence is described of the potential of a plant protease inhibitor, the potato carboxypeptidase inhibitor (pci), to provide resistance to fungal pathogens when expressed in rice as a heterologous protein. it is shown that rice plants constitutively expressing the pci gene exhibit resistance against the economically important pathogens magnaporthe oryzae and fusarium verticillioides. a m ...	2007	17547659
preceramic adoption of peanut, squash, and cotton in northern peru.	the early development of agriculture in the new world has been assumed to involve early farming in settlements in the andes, but the record has been sparse. peanut (arachis sp.), squash (cucurbita moschata), and cotton (gossypium barbadense) macrofossils were excavated from archaeological sites on the western slopes of the northern peruvian andes. direct radiocarbon dating indicated that these plants grew between 9240 and 5500 (14)c years before the present. these and other plants were recovered ...	2007	17600214
haploids: high-frequency production from single-embryo seeds in a line of pima cotton.	progenies of a doubled haploid from pima s-1, a commercial variety of gossypium barbadense l., contained a very high frequency of haploid plants. the haploid plants, in contrast with those previously reported in cotton, originated from single- rather than twin-embryo seeds. apparently the haploid-producing ability of this line of cotton is inherited.	1963	17799847
cotton remains from archeological sites in central coastal peru.	cotton remains from four archeological sites in central coastal peru, representing a time sequence from about 2500 to 1000 b.c., were compared with similar materials obtained from living wild and cultivated forms of gossypium barbadense l. the comparison revealed that the archeological cotton samples were primitive forms of gossypium barbadense, differing little from present-day wild forms of the same species. although not the earliest cottons recorded for the new world, they appear to represent ...	1973	17811658
a transgressive segregation factor (rkn2) in gossypium barbadense for nematode resistance clusters with gene rkn1 in g. hirsutum.	host plant resistance is an important strategy for managing root-knot nematode (meloidogyne incognita) in cotton (gossypium l.). here we report evidence for enhanced resistance in interspecific crosses resulting from transgressive segregation of clustered gene loci. recently, a major gene, rkn1, on chromosome 11 for resistance to m. incognita in cv. acala nemx was identified using an intraspecific g. hirsutum cross with susceptible cv. acala sj-2. using interspecific crosses of acala nemxxsuscep ...	2008	17940800
signaling pathways controlling induced resistance to insect herbivores in arabidopsis.	insect attack triggers changes in transcript level in plants that are mediated predominantly by jasmonic acid (ja). the implication of ethylene (et), salicylic acid (sa), and other signals in this response is less understood and was monitored with a microarray containing insect- and defense-regulated genes. arabidopsis thaliana mutants coi1-1, ein2-1, and sid2-1 impaired in ja, et, and sa signaling pathways were challenged with the specialist small cabbage white (pieris rapae) and the generalist ...	2007	17977152
identification of differentially expressed genes associated with cotton fiber development in a chromosomal substitution line (cs-b22sh).	one of the impediments in the genetic improvement of cotton fiber is the paucity of information about genes associated with fiber development. availability of chromosome arm substitution line cs-b22sh (chromosome 22 short arm substitution from 3-79 (gossypium barbadense) into a tm-1 (gossypium hirsutum) background) provides a novel opportunity to study fiber-associated genes because previous studies revealed this line was associated with some superior fiber quality traits compared to tm-1. we us ...	2008	18043952
plant crude extracts could be the solution: extracts showing in vivo antitumorigenic activity.	screening active compounds from plants lead to discover new medicinal drugs which have efficient protection and treatment roles against various diseases including cancer. in our study, extracts from different plants represent seeds of: gossypium barbadense, ricinus communis, sesamum indicum, nigella sativa, vinca rosea and melia azedarah; fruits of: xanthium occidental; flowers of: atriplex nummularia; barks of: cinnamomum zeylanicum; latex of: ficus carica and rhizomes of: curcuma longa and zin ...	2008	18390447
biological performance of quercetin on the cotton leaf-worm larvae, spodoptera littoralis boisd. (lep., noctuidae) and prevailing natural enemies in the egyptian cotton fields.	the egyptian cotton (gossypium barbadense l.) accounts for 65 % of the world production of long stable cultivars. taking into consideration the competition of other cotton producing countries, it should be of great importance to control pests, which attack the cotton plants to improve the yield and its quality. the main objective of this study is to develop new approaches for the management of the cotton leafworm spodoptera littoralis boisd. within an ipm program, that include synthetic insectic ...	2007	18399494
hplc preparation of the chiral forms of 6-methoxy-gossypol and 6,6'-dimethoxy-gossypol.	a concentrated mixture of gossypol, 6-methoxy-gossypol, and 6,6'-dimethoxy-gossypol was extracted from the root bark of st. vincent sea island cotton with acetone. this extract was derivatized with r-(-)-2-amino-1-propanol to form diastereomeric gossypol schiff's bases. analytical-scale reverse-phase chromatography of these schiff's bases produced six peaks, indicating separation of the enantiomeric forms of the three gossypol compounds. the elution order of the peaks was found to vary with the ...	2008	18407810
global analysis of gene expression in cotton fibers from wild and domesticated gossypium barbadense.	gossypium barbadense is widely cultivated because of its extra-long staple cotton with superior luster, silkiness and high yield. these economically important traits were selected during initial domestication of an agronomically inferior wild ancestor, followed by millennia of human-mediated selection. to reveal the effects of this history on the cotton fiber transcriptome, we conducted comparative expression profiling on mechanically isolated fiber cells at three different stages encompassing e ...	2008	18803775
a fusarium wilt resistance gene in gossypium barbadense and its effect on root-knot nematode-wilt disease complex.	abstract fusarium wilt, caused by the soilborne pathogen fusarium oxysporum f. sp. vasinfectum race 1, is a vascular disease in cotton (gossypium spp.), and is a component of a disease complex with root-knot nematodes (meloidogyne incognita). genetic analysis of two interspecific crosses (g. barbadense pima s-7 x g. hirsutum acala nemx and pima s-7 x acala sj-2) showed that one major gene (designated fov1) with allele dosage effect conferred resistance to f. oxysporum f. sp. vasinfectum race 1 i ...	2006	18943146
molecular cloning, expression profiling and functional analyses of a cdna encoding isopentenyl diphosphate isomerase from gossypium barbadense.	gossypol, a type of plant defence sesquiterpenoid phytoalexin, is synthesized from the mep (2c-methyl-d-erythritol 4-phosphate) and mva (mevalonate) pathway in the isoprenoid biosynthetic system. the key step is the isomerization of ipp (isopentenyl diphosphate) to dmapp (dimethylallyl diphosphate), which is catalysed by ipi (ipp isomerase; ec 5.3.3.2). a full-length cdna encoding ipi (designated gbipi) was cloned from gossypium barbadense by race (rapid amplification of cdna ends). the full-len ...	2009	19055484
starch grains on human teeth reveal early broad crop diet in northern peru.	previous research indicates that the nanchoc valley in northern peru was an important locus of early and middle holocene human settlement, and that between 9200 and 5500 (14)c yr b.p. the valley inhabitants adopted major crop plants such as squash (cucurbita moschata), peanuts (arachis sp.), and cotton (gossypium barbadense). we report here an examination of starch grains preserved in the calculus of human teeth from these sites that provides direct evidence for the early consumption of cultivat ...	2008	19066222
[cotton fiber quality traits were controlled mainly by maternal plant genotype].	hai1, a gossypium barbadense l. variety with super fiber quality, and ccri36 and zhong221, two upland cotton cultivars (gossypium hirsutum l.), were used as recurrent parents to develop two backcross combinations of ccri36xhai1 and zhong221xhai1. fiber quality of inter-crossing bolls and self-crossing bolls were analyzed from different generations of the two combinations. the results showed that there existed significant difference in the average value, pole difference and cv% of fiber quality t ...	2008	19073557
total and percent atropisomers of gossypol and gossypol-6-methyl ether in seeds from pima cottons and accessions of gossypium barbadense l.	gossypol occurs naturally in the seed, foliage, and roots of the cotton plant ( gossypium ) as atropisomers due to restricted rotation around the binaphthyl bond. the atropisomers differ in their biological activities. (-)-(r)-gossypol is more toxic and exhibits significantly greater anticancer activity than the (+)-(s)-atropisomer. most commercial upland ( gossypium hirsutum ) cottonseeds have an (r)- to (s)-gossypol ratio of approximately 2:3, but some pima ( gossypium barbadense ) seeds have ...	2009	19113939
genetic changes in plant growth and their associations with chromosomes from gossypium barbadense l. in g. hirsutum l.	cotton (gossypium spp.) plant growth is an important time-specific agronomic character that supports the development of squares, flowers, boll retention, and yield. with the use of a mixed linear model approach, we investigated 14 cotton chromosome substitution (cs-b) lines and their chromosome-specific f(2) hybrids for genetic changes in plant growth that was measured during the primary flowering time under two environments. the changes in additive and dominance variances for plant height and n ...	2009	19153810
molecular cloning and characterization of the actin-depolymerizing factor gene in gossypium barbadense.	the sea island cotton (gossypium barbadense l.) has been highly valued in verticillium wilt resistance and many fiber qualities including fiber length, strength and fineness. to identify whether it had some special genes in fiber development in comparison with the upland cotton (g. hirsutum l.), an actin-depolymerizing factor (adf) gene was cloned and characterized in this research. a 420 bp open reading frame of the cloned gene, named gbadf1, encoded a protein of 139 amino acids, including 39.5 ...	2008	19168989
the effects of different prey regimes on the proteolytic digestion of nymphs of the spined soldier bug, podisus maculiventris (hemiptera: pentatomidae).	the effects of different prey regimes on the performance and digestive physiology of the spined soldier bug, podisus maculiventris (say) (hemiptera: pentatomidae), were assessed. specifically, p. maculiventris nymphs were fed on colorado potato beetle (cpb), leptinotarsa decemlineata say (coleoptera: chrysomelidae), larvae; egyptian cotton leafworm (ecw); spodoptera littoralis (boisduval) (lepidoptera: noctuidae); larvae; calliphora spp. (cal) (diptera: calliphoridae) pupae or a mixture of the t ...	2009	19203402
clock-controlled rhythm of ecdysteroid levels in the haemolymph and testes, and its relation to sperm release in the egyptian cotton leafworm, spodoptera littoralis.	in spodoptera littoralis, testicular sperm release occurs in a daily rhythm, which is controlled by endogenous circadian oscillator located in the male reproductive system. although this rhythm is essential for male fertility, factors that initiate and maintain daily sperm release are not understood. in this study, we investigated a modulatory role for ecdysteroids in the sperm release rhythm and identified the source of ecdysteroids in adult males. we found that the onset of sperm release occur ...	2009	19233333
resistance to meloidogyne incognita race 3 and rotylenchulus reniformis in wild accessions of gossypium hirsutum and g. barbadense from mexico.	forty-six accessions of g. hirsutum and two of g. barbadense were examined for resistance to meloidogyne incognita race 3 and rotylenchulus reniformis in environmental growth chamber experiments, with the objective of finding new sources of resistance. only the g. barbadense accessions, tx-1347 and tx-1348, supported significantly less reproduction by r. reniformis than the susceptible control, deltapine 16 (usda accession sa-1186). however, they were highly susceptible to m. incognita race 3. t ...	1997	19274280
effects of 1,3-dicliloropropene for meloidogyne incognita management on cotton produced under furrow irrigation.	field trials were conducted during 1990 to evaluate the effects of preplant soil fumigation with 1,3-dichloropropene (1,3-d) on yield and fiber quality of furrow-irrigated cotton cultivars subjected to high population densities of meloidogyne incognita. we measured the responses of eight upland cotton cultivars with different levels of root-knot nematode resistance and compared the responses of upland and pima cottons. reductions in lint weight ranged from 10 to 52% among cultivars grown in soil ...	1993	19279835
resistance to bacterial blight of cotton varieties homozygous for combinations of b resistance genes.	in the sudan, inoculation experiments were done on a wide range of egyptian cotton lines homozygous for single genes and for digenic and trigenic combinations of knight's b genes for resistance to bacterial blight. although leaf inoculation was successful, stem inoculation was only partially so and boll inoculation, using two different techniques, failed to produce measurable disease symptoms. there was a good general relationship between leaf and stem resistance, and a close association between ...	1974	19280793

peripheral modulation of olfaction by physiological state in the egyptian leaf worm spodoptera littoralis (lepidoptera: noctuidae).	insects show behavioural plasticity based on their physiological state. deprivation from a resource will normally make them more responsive to it or to perform behaviour increasing the probability of encountering such a resource. modulation of the olfactory system has been shown mainly in the central nervous system, but also in the periphery. in this study, antennal sensitivity of females of the egyptian cotton leaf worm spodoptera littoralis to different plant and sex pheromone odours was measu ...	2009	19414013
potential of "lure and kill" in long-term pest management and eradication of invasive species.	"lure and kill" technology has been used for several decades in pest management and eradication of invasive species. in lure and kill, the insect pest attracted by a semiochemical lure is not "entrapped" at the source of the attractant as in mass trapping, but instead the insect is subjected to a killing agent, which eliminates affected individuals from the population after a short period. in past decades, a growing scientific literature has been published on this concept. this article provides ...	2009	19610395
[analysis on linkage inheritance of sub-red plant mutant from upland cotton].	analysis of linkage inheritance of sub-red plant, a natural mutant from upland cotton, was conducted by two-point test using parents gossypium barbadense hai7124 and g. hirsutum b026 both with petal spots and green leaves, and g. hirsutum e083 with normal white flowers and, sub-red plants. the average percentage of recombination was 1.35% when calculating test-cross combining populations derived from e083/b026//su9701 and b026/e083//su9701. the average percentage of recombination was 2.94% when ...	2009	19689948
the phytohormone precursor opda is isomerized in the insect gut by a single, specific glutathione transferase.	oxylipins play important roles in stress signaling in plants. the compound 12-oxophytodienoic acid (cis-opda) is an early biosynthetic precursor of jasmonic acid (ja), the key phytohormone orchestrating the plant anti-herbivore defense. when consumed by feeding lepidopteran larvae, plant-derived cis-opda suffers rapid isomerization to iso-opda in the midgut and is excreted in the frass. unlike opda epimerization (yielding trans-opda), the formation of iso-opda is enzyme-dependent, and is catalyz ...	2009	19805297
sampling nucleotide diversity in cotton.	cultivated cotton is an annual fiber crop derived mainly from two perennial species, gossypium hirsutum l. or upland cotton, and g. barbadense l., extra long-staple fiber pima or egyptian cotton. these two cultivated species are among five allotetraploid species presumably derived monophyletically between g. arboreum and g. raimondii. genomic-based approaches have been hindered by the limited variation within species. yet, population-based methods are being used for genome-wide introgression of ...	2009	19840401
functional analysis of gbagl1, a d-lineage gene from cotton (gossypium barbadense).	cotton fibres originate from the outer ovule integument and d-lineage genes are essential for ovule development and their roles can be described by the 'abcde' model of flower development. to investigate the role of d-lineage genes during ovule and fibre development, gbagl1 (genbank accession number: fj198049) was isolated from g. barbadense by using the smart race strategy. sequence and phylogenetic analyses revealed that gbagl1 was a member of the d-lineage gene family. southern blot analysis ...	2010	20054032
identification and expression profile of gbagl2, a c-class gene from gossypium barbadense.	an agamous (ag)-like gene, gbagl2, was isolated from gossypium barbadense and characterized. alignment and phylogenetic analysis indicated that gbagl2 shared high homology with ag-subfamily genes and belonged to a c-class gene family. dna gel blot analysis showed that gbagl2 belonged to a low-copy gene family. reverse transcriptase-polymerase chain reaction (rt-pcr) and quantitative real-time pcr (qpcr) revealed that gbagl2 was highly expressed in reproductive tissues including ovules and carpel ...	2009	20093747
genetic dissection of chromosome substitution lines of cotton to discover novel gossypium barbadense l. alleles for improvement of agronomic traits.	we recently released a set of 17 chromosome substitution (cs-b) lines (2n = 52) that contain gossypium barbadense l. doubled-haploid line '3-79' germplasm systematically introgressed into the upland inbred 'tm-1' of g. hirsutum (l.). tm-1 yields much more than 3-79, but cotton from the latter has superior fiber properties. to explore the use of these quasi-isogenic lines in studying gene interactions, we created a partial diallel among six cs-b lines and the inbred tm-1, and characterized their ...	2010	20094702
a thaumatin-like protein gene involved in cotton fiber secondary cell wall development enhances resistance against verticillium dahliae and other stresses in transgenic tobacco.	for the first time, a sea-island cotton (gossypium barbadense l.) thaumatin-like protein gene (gbtlp1) with a potential role in secondary cell wall development has been overexpressed in tobacco to elucidate its function. the presence of the transgene was verified by southern blotting and higher expression levels of gbtlp1 in transgenic tobacco plants were revealed by reverse-transcription and quantitative real-time polymerase chain reaction analyses. transgenic plants with constitutively higher ...	2010	20097164
ethnomedicine and ethnobotany of fright, a caribbean culture-bound psychiatric syndrome.	"fright" is an english-speaking caribbean idiom for an illness, or ethnomedical syndrome, of persistent distress. a parallel ethnopsychiatric idiom exists in the french antilles as sésisma. fright is distinct from susto among hispanics, though both develop in the wake of traumatic events. west indian ethnophysiology (ethnoanatomy) theorizes that an overload of stressful emotions (fear, panic, anguish or worry) causes a cold humoral state in which blood coagulates causing prolonged distress and i ...	2010	20163730
chlorpyrifos exposures in egyptian cotton field workers.	neurobehavioral deficits have been reported in egyptian pesticide application teams using organophosphorus (op) pesticides, but whether these effects are related to op pesticide exposures has yet to be established. in preparation for a comprehensive study of the relationship between op pesticide dose and neurobehavioral deficits, we assessed exposure within this population. we conducted occupational surveys and workplace observations, and collected air, dermal patch and biological samples from a ...	2010	20193710
penetration and biodegradation of carbaryl in susceptible and resistant strains of the egyptian cotton leafworm.		1971	20333837
preliminary studies for the development of a second generation granulocytapheresis (g-cap) column.	the preliminary studies for developing a second generation granulocytapheresis (g-cap) column were made. in the past, the g-cap column has been used for the treatment of ulcerative colitis and rheumatoid arthritis. however, recent clinical studies have revealed that the therapeutic effects of the g-cap column are not significant compared with those of the sham column. these results were considered to be due to insufficient reduction of granulocytes. thus, development of a better granulocyte remo ...	2010	20364286
an l1 box binding protein, gbml1, interacts with gbmyb25 to control cotton fibre development.	transcription factors play key roles in plant development through their interaction with cis-elements and/or other transcription factors. a hd-zip iv family transcription factor, gossypium barbadense meristem layer 1 (gbml1) has been identified and characterized here. gbml1 specifically bound to the l1 box and the promoters of gbml1 and gbrdl1. gbml1 physically interacted with a key regulator of cotton fibre development, gbmyb25. truncated and point mutation assays indicated the start-sad domain ...	2010	20667961
identification of qtl regions and ssr markers associated with resistance to reniform nematode in gossypium barbadense l. accession gb713.	the identification of molecular markers that are closely linked to gene(s) in gossypium barbadense l. accession gb713 that confer a high level of resistance to reniform nematode (rn), rotylenchulus reniformis linford & oliveira, would be very useful in cotton breeding programs. our objectives were to determine the inheritance of rn resistance in the accession gb713, to identify ssr markers linked with rn resistance qtls, and to map these linked markers to specific chromosomes. we grew and scored ...	2011	20845024
study of the bacillus thuringiensis vip3aa16 histopathological effects and determination of its putative binding proteins in the midgut of spodoptera littoralis.	the bacterium bacillus thuringiensis produces, at the vegetative stage of its growth, vip3a proteins with activity against a broad spectrum of lepidopteran insects. the egyptian cotton leaf worm (spodoptera littoralis) is an important agricultural pest that is susceptible to the vip3aa16 protein of bacillus thuringiensis kurstaki strain bupm95. the midgut histopathology of vip3aa fed larvae showed vacuolization of the cytoplasm, brush border membrane destruction, vesicle formation in the apical ...	2010	20965198
molecular cloning and expression analysis of a novel sant/myb gene from gossypium barbadense.	myb family transcription factors are implicated in multiple developmental processes. herein, a new full-length cdna encoding a sant/myb transcription factor (designated as gbrl2) was cloned and characterized from cotton (gossypium barbadense l.) for the first time. the full-length cdna of gbrl2 was 573 bp with a 240 bp open reading frame (orf) encoding a deduced protein of 80 amino acid polypeptide with a calculated molecular mass of 8.96 kda and an isoelectric point of 8.96. sequence alignment ...	2010	21069464
genistein effects on haematoimmune cells in a newly developed alternative toxicological model.	unexpected, sometimes opposite effects of dietary isoflavonic phytoestrogens on immunity may suggest that classical mammalian toxicological assays are not entirely suitable for preclinical safety tests of these compounds. we evaluated a new alternative model of haemocytes of egyptian cotton worm in vivo following genistein administration. genistein induced significant changes in nucleolar morphology of haemocytes but did not influence their counts and nucleolar indices. the results indicate that ...	2012	21095109
comparative expression of mirna genes and mirna-based aflp marker analysis in cultivated tetraploid cottons.	micrornas (mirnas) are a class of small non-coding rnas that down-regulate gene expression in a sequence specific manner to control plant growth and development. the identification and characterization of mirnas are critical steps in finding their target genes and elucidating their functions. the objective of the present study was to assess the genetic variation of mirna genes through expression comparisons and mirna-based aflp marker analysis. seven mirnas were first selected for rt-pcr and fou ...	2011	21134704
metabolite and mineral analyses of cotton near-isogenic lines introgressed with qtls for productivity and drought-related traits.	quantitative trait loci (qtls) for yield and drought-related traits were exchanged via marker-assisted selection between elite cultivars of two cotton species, gossypium barbadense (gb) cv. f-177 and gossypium hirsutum (gh) cv. siv'on. three of the resultant near-isogenic lines (nils), each introgressed with a different qtl region, expressed an advantage in osmotic adjustment (oa) and other drought-related traits relative to their recipient parents. these nils and the parental genotypes were fie ...	2011	21143238
opportunistic nature of the mammalian microsporidia: experimental transmission of trachipleistophora extenrec (fungi: microsporidia) between mammalian and insect hosts.	spores of trachipleistophora extenrec, originally isolated from the muscles of the madagascan insectivore hemicentetes semispinosus and maintained by serial passage in severe combined immunodeficiency (scid) mice, were fed to larvae of the egyptian cotton leafworm spodoptera littoralis. extensive infection of larval tissues ensued and caused larval and pupal mortality. the development of t. extenrec in the insect host, studied both by light and electron microscopy, followed generally the same li ...	2010	21188601
biomarkers of chlorpyrifos exposure and effect in egyptian cotton field workers.	chlorpyrifos (cpf), a widely used organophosphorus pesticide (op), is metabolized to cpf-oxon, a potent cholinesterase (che) inhibitor, and trichloro-2-pyridinol (tcpy). urinary tcpy is often used as a biomarker for cpf exposure, whereas blood che activity is considered an indicator of cpf toxicity. however, whether these biomarkers are dose related has not been studied extensively in populations with repeated daily op exposures.	2011	21224175
structure, expression differentiation and evolution of duplicated fiber developmental genes in gossypium barbadense and g. hirsutum.	both gossypium hirsutum and g. barbadense probably originated from a common ancestor, but they have very different agronomic and fiber quality characters. here we selected 17 fiber development-related genes to study their structures, tree topologies, chromosomal location and expression patterns to better understand the interspecific divergence of fiber development genes in the two cultivated tetraploid species.	2011	21349199
identification of differentially expressed genes associated with semigamy in pima cotton (gossypium barbadense l.) through comparative microarray analysis.	semigamy in cotton is a type of facultative apomixis controlled by an incompletely dominant autosomal gene (se). during semigamy, the sperm and egg cells undergo cellular fusion, but the sperm and egg nucleus fail to fuse in the embryo sac, giving rise to diploid, haploid, or chimeric embryos composed of sectors of paternal and maternal origin. in this study we sought to identify differentially expressed genes related to the semigamy genotype by implementing a comparative microarray analysis of ...	2011	21410961
among-sampler variation in sweep net samples of adult lygus hesperus (hemiptera: miridae) in cotton.	the sweep net is a standard sampling method for adults of the western tarnished plant bug, lygus hesperus knight (hemiptera: miridae), in cotton (gossypium spp.). however, factors that influence the relationship between true population levels and population estimates obtained using the sweep net are poorly documented. improved understanding of these factors is needed for the development and application of refined treatment thresholds. recent reports of significant among-sampler differences in sw ...	2011	21510222
