| selecting for efficacy of bollgard cotton cultivars against various lepidoptera using forward breeding techniques. | studies during the past 5 yr have shown that the overall level of protein (cry1ac) produced from the cry1ac transgene (monsanto co., st. louis, mo) differ among commercial bollgard cotton, gossypium hirsutum l., cultivars. these differences between cultivars are under genetic control and have been correlated with efficacy of certain lepidopteran pests. previous studies have shown that the parental background (i.e., non-cry1ac conventional cultivar) has a significant influence on the amount of cr ... | 2006 | 17066820 |
| evaluation of source leaf responses to water-deficit stresses in cotton using a novel stress bioassay. | water-deficit stresses preferentially reduce shoot growth, thereby disrupting the flow of carbohydrates from source leaves to the developing sinks. here, we use a novel stress bioassay to dissect responses of field and greenhouse-grown cotton (gossypium hirsutum) source leaves to water-deficit stresses. fifth main stem leaf samples were harvested at sunrise and subjected to a prolonged elevated respiratory demand in the dark. sucrose levels are lower in nonstressed cotton at sunrise compared to ... | 2007 | 17071650 |
| [cloning of ghaqp1 gene and its specific expression during ovule development in cotton]. | plant aquaporins, belonging to the mip superfamily, are a series of transmembrane proteins that facilitate water transport through cell membranes. in this study, a cdna clone encoding the pip1-like protein was isolated from cotton (gossypium hirsutum) cdna libraries, and designated as ghaqp1 (fig.1). we also isolated the ghaqp1 gene from cotton genome by pcr. the gene is 2,096 bp in length, including an open reading frame (orf) and 5'-/3'-untranslated regions (utr). it contains two introns in it ... | 2006 | 17075177 |
| [isolation by suppression-subtractive hybridization of genes preferentially expressed during early and late fiber development stages in cotton]. | as a main natural fiber source, cotton plays an important role in human life. to identify genes preferentially expressed during early and late cotton fiber development, we constructed two fiber subtracted libraries on the basis of pcr-selected subtraction using a pool of nonfiber tissues as the same driver and 10 days postanthesis (dpa) and 20 dpa fiber cells as testers, respectively. through differential screening, 292 clones in both libraries were identified as being preferentially expressed d ... | 2006 | 17086983 |
| [structural-functional organization of chloroplasts in leaves of xantha-702 mutant of gossypium hirsutum l]. | for cotton mutant xantha (gossypium hirsutum l.), it has been established that synthesis of 5-aminolevulinic acid was blocked in the light. in the light this mutant accumulates chlorophyll by 30 times lower as compared to the parent type. in mutant xantha, a very few pigment-protein complexes of ps-i and ps-ii are formed in chloroplasts, and formation of membrane system in these is blocked at the early stages, in most cases, at the stage of bubbles and single short thylakoids. functional activit ... | 2006 | 17087145 |
| molecular characterization and expression analysis of nine cotton ghef1a genes encoding translation elongation factor 1a. | the translation elongation factor 1a, eef1a, plays an important role in protein synthesis, catalyzing the binding of aminoacyl-trna to the a-site of the ribosome by a gtp-dependent mechanism. to investigate the role of eef1a for protein synthesis in cotton fiber development, nine different cdna clones encoding eukaryotic translation elongation factor 1a were isolated from cotton (gossypium hirsutum) fiber cdna libraries. the isolated genes (cdnas) were designated cotton elongation factor 1a gene ... | 2007 | 17107762 |
| enhanced degradation of atrazine under field conditions correlates with a loss of weed control in the glasshouse. | enhanced degradation of atrazine has been reported in the literature, indicating the potential for reduced residual weed control with this herbicide. experiments were conducted to determine the field dissipation of atrazine in three cropping systems: continuous zea mays l. (cc) receiving atrazine applications each year, gossypium hirsutum l.-z. mays rotation (ccr) receiving applications of atrazine once every 2 years and a no atrazine history soil (nah). subsequent laboratory and greenhouse expe ... | 2007 | 17115404 |
| xenia effect on seed and embryo size in cotton (gossypium hirsutum l.). | the term xenia was coined to describe the effect of foreign pollen on the development and characters of the seed. to study its importance and consequences for various seed traits in cotton (gossypium hirsutum l.), the effect of pollen genotype on seed and embryo weight was studied with seeds from 15 f1 hybrids. cross-fertilization changed seed weight by up to 7.0% in relation to self-fertilization. xenia effect significantly increased embryo weight of cross-fertilized seeds, by up to 14.4% in co ... | 2006 | 17132897 |
| disease resistance conferred by the expression of a gene encoding a synthetic peptide in transgenic cotton (gossypium hirsutum l.) plants. | fertile, transgenic cotton plants expressing the synthetic antimicrobial peptide, d4e1, were produced through agrobacterium-mediated transformation. pcr products and southern blots confirmed integration of the d4e1 gene, while rt-pcr of cotton rna confirmed the presence of d4e1 transcripts. in vitro assays with crude leaf protein extracts from t0 and t1 plants confirmed that d4e1 was expressed at sufficient levels to inhibit the growth of fusarium verticillioides and verticillium dahliae compare ... | 2005 | 17147626 |
| genetics of resistance to cotton leaf curl disease in gossypium hirsutum l. under field conditions. | one hundred and forty two cotton germplasm lines were screened for cotton leaf curl virus symptoms in field evaluations during 2003, 2004, and 2005. fifty cross combinations involving 30 of these lines classified resistant or susceptible were used for inheritance study of the disease. all the f(1) plants of crosses involving resistant x resistant, resistant x susceptible, and susceptible x resistant parents were resistant, indicating dominant expression of the disease resistance and there were n ... | 2007 | 17159229 |

| cadherin-based resistance to bacillus thuringiensis cotton in hybrid strains of pink bollworm: fitness costs and incomplete resistance. | recessive resistance to bacillus thuringiensis (bt) cotton, gossypium hirsutum l., in laboratory-selected strains of pink bollworm, pectinophora gossypiella (saunders), is associated with three resistance alleles (r1, r2, and r3) of a cadherin gene. previous experiments based on measurement of fitness components in bt-resistant and bt-susceptible strains revealed that fitness costs and incomplete resistance are associated with resistance. here, we used two hybrid strains of pink bollworm, each c ... | 2006 | 17195656 |
| modeling the impact of alternative hosts on helicoverpa zea adaptation to bollgard cotton. | for highly polyphagous cotton, gossypium hirsutum l., pests such as helicoverpa zea (boddie), a substantial portion of the larval population develops on noncotton alternative hosts. these noncotton hosts potentially provide a natural refuge for h. zea, thereby slowing the evolution of resistance to the bacillus thuringiensis berliner (bt)-derived cry1ac protein present in bollgard cotton. here, we demonstrate how the measured contribution of such alternative hosts can be included in estimating t ... | 2006 | 17195681 |
| high-level resistance to bacillus thuringiensis toxin crylac and cadherin genotype in pink bollworm. | resistance to transgenic cotton, gossypium hirsutum l., producing bacillus thuringiensis (bt) toxin cry1ac is linked with three recessive alleles of a cadherin gene in laboratory-selected strains of pink bollworm, pectinophora gossypiella (saunders), a major cotton pest. here, we analyzed a strain (mov97-r) with a high frequency of cadherin resistance alleles, a high frequency of resistance to 10 microg of cry1ac per milliliter of diet, and an intermediate frequency of resistance to 1000 microg ... | 2006 | 17195682 |
| a rapid single-step multiplex method for discriminating between trichogramma (hymenoptera: trichogrammatidae) species in australia. | inaccurate species identification confounds insect ecological studies. examining aspects of trichogramma ecology pertinent to the novel insect resistance management strategy for future transgenic cotton, gossypium hirsutum l., production in the ord river irrigation area (oria) of western australia required accurate differentiation between morphologically similar trichogramma species. established molecular diagnostic methods for trichogramma identification use species-specific sequence difference ... | 2006 | 17195685 |
| molecular cloning and expression analysis of a ranbp2 zinc finger protein gene in upland cotton (gossypium hirsutum l.). | gossypol is an important resistant substance of gossypium, and its storage organ is pigment gland. although, the relationship between gossypol and pigment gland has been studied for a long time, the development mechanism of pigment gland has not been revealed up to now in molecular perspective. on the basis of differentially expressed cdnas fragments at the stage of the cotton gland development using suppression subtractive hybridization (ssh), the complete cdna sequence of a novel ranbp2 zinc f ... | 2007 | 17223018 |
| identification and characterization of the novel gene ghdbp2 encoding a dre-binding protein from cotton (gossypium hirsutum). | a cdna encoding one novel dre-binding protein, ghdbp2, was isolated from cotton seedlings. it is classified into the a-6 group of dreb subfamily based on multiple sequence alignment and phylogenetic characterization. using semi-quantitative rt-pcr, we found that the ghdbp2 transcripts were greatly induced by drought, nacl, low temperature and aba treatments in cotton cotyledons. the dna-binding properties of ghdbp2 were analyzed by electrophoretic mobility shift assay (emsa), showing that ghdbp2 ... | 2008 | 17224201 |
| centromere orientation of quadrivalents of heterozygous translocations and an autoploid of gossypium hirsutum l. | cytological observations of quadrivalents of heterozygous translocations in gossypium hirsutum l. demonstrate that, in addition to alternate-1 and alternate-2 orientations, a third alternate orientation (alternate-3), which occurs as a three-dimensional, v-type configuration, can be identified.-two additional types of disjunctions, the centromere orientations of which are rotational modifications of either adjacent or alternate configurations, were also observed in quadrivalents of a translocati ... | 1983 | 17246172 |
| transmission of duplication-deficiencies from cotton translocations is unrelated to map lengths of the unbalanced segments. | adjacent-1 duplication-deficiencies (dp-dfs) are readily recovered from most heterozygous translocations in gossypium hirsutum l., but frequencies of specific cytotypes differ widely in progenies from heterozygote (female symbol) x standard crosses. surprisingly, these frequencies seem to be unrelated to the primary (postmeiotic) frequencies predicted by metaphase i configurations or to the proportion of the chromosome arm that is duplicate or deficient. deficiencies and duplications from differ ... | 1987 | 17246386 |
