variable methylation and differential replication of genomic dna in cultured carrot root expiants during growth induction as influenced by hormonal treatments.the methylation and amplification pattern of genomic dna of carrot root expiants (daucus carota l.) undergoes transitory changes during the cultural cycle. a high degree of variation was observed as early as 36 h after the incubation of fresh expiants in the nutrient medium and, depending on the hormonal treatment significant modifications occurred during 14 days of culture. proliferative tissue conditioned by kinetin showed an extensive reduction in dna methylation. changes in the dna amplifica ...199124213171
the impact of domestication on the genetic variability in the orange carrot, cultivated daucus carota ssp. sativus and the genetic homogeneity of various cultivars.isozyme analysis of wild and domesticated accessions indicated that domestication of the cultivated carrot daucus carota ssp. sativus resulted in an insignificant reduction of all genetic variability and genetic distance estimates. although they are less variable genetically, cultivated forms maintain a high proportion of observed heterozygosity. relative to the overall genetic variability of the species, samples from four common cultivars 'red cored chantenay', 'scarlet nantes', 'danvers half l ...199124213074
microtubule-binding proteins from carrot : i. initial characterization and microtubule bundling.microtubules (mts) participate in several processes of fundamental importance to growth and development in higher plants, yet little is known about the proteins with which they associate. information about these molecules is important because they probably play a role in mediating functional and structural differences between various mt arrays. as a first step in gaining insight into this problem, we have isolated, from suspension-cultured cells of carrot (daucus carota l.), non-tubulin proteins ...198924212347
modulation of auxin-binding proteins in cell suspensions : ii. isolation and initial characterization of carrot cell variants impaired in somatic embryogenesis.cultured cell lines from carrot (daucus carota l.) with little or no embryogenic potential were examined for the auxin-binding capacity of their membranes. the lines belonged to different classes: (a) wild-type lines kept in culture for different periods (the longer the period, the lower being their embryogenic potential); (b) variants, isolated after mutagenesis, showing normal growth but a lack of embryogenic response; (c) auxin-resistant lines, isolated as colonies on solid media containing 4 ...199224203204
the effect of growth retardants on anthocyanin production in carrot cell suspension cultures.the effect of growth retardants on anthocyanin production was studied in wild carrot (daucus carota) cell suspension cultures. paclobutrazol [(2rs,3rs) - 1 - (4-chlorophenyl) - 4,4 -dimethyl-2-(1,2,4-triazol-1-yl) pentan-3-ol], uniconazole [(e)-1-(4-chlorophenyl-4,4 -) dimethyl-2-(1,2,4-triazol-1-yl)-1-penten-3-ol], tetcyclacis [5-(4-chloro-phenyl) -3,4,5,9,10-pentaaza-tetracyclo-5, 4, 10(2,6), o(8,11) - dodeca-3, 9-diene], ancymidol [α-cyclopropyl - 4 - methoxy-α(pyrimidine-5-yl)benzyl alcohol] ...199224203145
unique patterns of mitochondrial genes, transcripts and proteins in different male-sterile cytoplasms of daucus carota.restriction fragment analysis of mitochondrial and chloroplast dnas from a brown anther and a petaloid cytoplasmic male-sterile (cms) line revealed unique patterns for each cms line distinct from those of normal fertile cytoplasms, but identical restriction fragments for all chloroplast dnas. the restauration of fertility through the introduction of nuclear restorer genes had no effect on the overall mitochondrial dna (mtdna) structure. the genomic environment and transcription patterns of sever ...199224202587
patterns of expression of the jim4 arabinogalactan-protein epitope in cell cultures and during somatic embryogenesis in daucus carota l.spatiotemporal patterns of expression of the cell-surface arabinogalactan-protein epitope defined by monoclonal antibody jim4 (j.p. knox et al., 1989, development 106, 47-56) have been characterized by indirect immunofluorescence during the process of somatic embryogenesis in daucus carota l. the jim 4 epitope (j4e) occurred on cells established in culture from hypocotyl explants which appeared to derive, at least in part, from the epidermal cells of the hypocotyl. cultures maintained in the pre ...199024201958
identification of a wound-induced inhibitor of a nuclear factor that binds the carrot extensin gene.following wounding of carrot (daucus carota l.) roots, the activity of a nuclear factor (egbf-1) that binds a 5'-region of the carrot extensin gene declines to undetectable levels within 48 h. mixing of nuclear extracts from wounded roots with nuclear extracts from unwounded roots has demonstrated the existence of a wound-induced inhibitor of egbf-1. inhibition of egbf-1 dna-binding activity by nuclear extracts from wounded roots is shown to be specific for egbf-1, and to be destroyed by heat tr ...198924201846
induction of chalcone synthase in cell suspension cultures of carrot (daucus carota l. spp. sativus) by ultraviolet light: evidence for two different forms of chalcone synthase.two cell lines of carrot (daucus carota l. spp. sativus), grown as cell-suspension cultures in the dark, were irradiated with ultraviolet light (315-420 nm) 10 d after the onset of cultivation. chalcone synthase (chs) enzyme activity was induced in both cell lines. anthocyanin synthesis was only stimulated in the anthocyanin-containing cell line dcb. parallel to the increase in chs activity there was an increase with time in the amount of one chs form with an isoelectric point of 6.5 and a molec ...198924201661
structural analysis of the cell walls regenerated by carrot protoplasts.a procedure was developed to isolate protoplasts rapidly from carrot (daucus carota l. cv. danvers) cells in liquid culture. high purity of cell-wall-degrading enzymes and ease of isolation each contributed to maintenance of viability and initiation of regeneration of the cell wall by a great majority of the protoplasts. we used this system to re-evaluate the chemical structure and physical properties of the incipient cell wall. contrary to other reports, callose, a (1 → 3)β-d-glucan whose synth ...198924201658
site-specific binding of a nuclear factor to the carrot extensin gene is influenced by both ethylene and wounding.experiments conducted in vitro using the electrophoretic mobility shift assay have shown that a single region of the extensin gene of carrot (daucus carota l.) interacts with a protein factor designated extensin gene binding factor-1 (egbf-1) present in nuclear extracts obtained from carrot roots. this interaction is sequence-specific as judged by the failure of other plant gene sequences to compete with the extensin gene for egbf-1 binding. the egbf-1 activity is organspecific, not being expres ...198924201417
influence of a specific xyloglucan-nonasaccharide derived from cell walls of suspension-cultured cells of daucus carota l. on regenerating carrot protoplasts.a xyloglucan oligosaccharide was isolated from cell walls of daucus carota l. suspension-cultured cells. from analytical data (gel-permeation chromatography, thin-layer chromatography, monosaccharide analysis, methylation analysis) it can be concluded that this oligosaccharide preparation consists mainly of a nonasaccharide known as xg9 (glc4xyl3galfuc). this nonasaccharide showed excellent "anti-auxin" properties in the pea-stem bioassay, with 80% inhibition of 2,4-dichlorophenoxyacetic acid (2 ...199024197092
pectin esterification is spatially regulated both within cell walls and between developing tissues of root apices.monoclonal antibodies recognizing un-esterified (jim5) and methyl-esterified (jim7) epitopes of pectin have been used to locate these epitopes by indirect immunofluorescence and immunogold electron microscopy in the root apex of carrot (daucus carota l.). both antibodies labelled the walls of cells in all tissues of the developing root apex. immunogold labelling observed at the level of the electron microscope indicated differential location of the pectin epitopes within the cell walls. the un-e ...199024196931
rapid changes in amplification and methylation pattern of genomic dna in cultured carrot root explants (daucus carota l.).rapid genomic dna variation due to methylation and copy number alteration was observed in carrot root explants 6 h after inoculation and during a 36-h period of exponential callus growth. de novo methylation and amplification of restricted bspni fragments of low molecular weight occurred before cell cycle activation and should, therefore, be independent of progression through the s-phase of the cell cycle. growth regulators seemed to influence the amplification pattern indirectly by regulating c ...199324196052
tunicamycin-inhibited carrot somatic embryogenesis can be restored by secreted cationic peroxidase isoenzymes.somatic embryogenesis of carrot (daucus carota l.) is inhibited by the glycosylation inhibitor tunicamycin. this inhibition is reversible by the addition of correctly glycosylated glycoproteins which have been secreted into the culture medium. to identify the proteins responsible for complementation, glycoproteins present in the medium of embryo cultures were purified and tested for their activity in the tunicamycin inhibition/ complementation assay. a 38-kda glycoprotein was purified that could ...199124194238
metabolic changes in carrot cells in response to simultaneous treatment with ultraviolet light and a fungal elicitor.ultraviolet light induces anthocyanin biosynthesis in cell cultures of an afghan cultivar of daucus carota (daucus carota l. ssp. sativus). simultaneous treatment with a fungal elicitor from pythium aphanidermatum results in an inhibition of the catalytic activity of chalcone synthase (chs), which in turn correlates with an inhibition of anthocyanin biosynthesis. on immunoblots, one isoenzyme (40 kda) of chs disappears upon elicitor treatment. on an mrna level, only the mrna for the 40-kda-chs i ...199124194154
gene expression during induction of somatic embryogenesis in carrot cell suspensions.we report the identification, via their cdnas, of genes which are temporarily transcribed during the initiation of somatic embryogenesis in carrot (daucus carota l.) cells cultured in an auxin-free medium. their expression is roughly associated with the first morphogenetic, or globular, stage. a cdna library (λ gt 10) was established using poly(a)(+) -rich rnas from cells deprived of auxin for 8 d. by differential screening a number of clones corresponding to early-induced embryogenic genes were ...199124193528
acylation of anthocyanins with hydroxycinnamic acids via 1-o-acylglucosides by protein preparations from cell cultures of daucus carota l.protein preparations from cell-suspension cultures of an afghan cultivar of daucus carota (carrot) catalyzed the formation of acylated anthocyanins from a cyanidin triglycoside isolated from the carrot cultures using (1-o-sinapoyl-, 1-o-feruloyl-) and 1-o-(p-coumaroyl)-β-glucose as acyl donors. the enzyme activities can be classified as 1-o-hydroxycinnamoyl-β-glucose: cyanidin 3-o-(2″-o-xylosyl-6″-o-glucosylgalactoside) 6‴-o-hydroxycinnamoyltransferases (ec 2.3.1.-).199224186789
partial amino-acid sequence of ecp31, a carrot embryogenic-cell protein, and enhancement of its accumulation by abscisic acid in somatic embryos.ecp31, an embryogenic-cell protein from carrot (daucus carota l.), was purified by sequential column-chromatographic steps and digested by v8 protease on a nitrocellulose membrane. the resultant peptides were separated by reverse-phased column chromatography and sequenced. the sequences obtained were 70-80% homologous to those of a late-embryogenesis-abundant protein (d34) from cotton (baker et al, 1988, plant mol. biol. 11, 227-291). the level of ecp31 in somatic embryos of carrot was increased ...199224186729
initiation and proliferation of carrot callus using a combination of antibiotics.calli were initiated from carrot (daucus carota l. subsp. sativus hoffm.) root expiants and grown on media supplemented with a combination of carbenicillin at 0.3 mg/ml and vancomycin at 0.1 mg/ml in the absence of plant hormones or hormone analogs. the growth rate was about half of that obtained with a combination of α-naphthaleneacetic acid and n(6)-benzyladenine at 1 mg/l each. carbenicillin in the combination with vancomycin could be replaced by penicillin g; other penicillins tested in this ...199124186530
levels of p34(cdc2)-like protein in dividing, differentiating and dedifferentiating cells of carrot.p34(cdc2) is a key cell-cycle protein in fission yeast that is necessary for progress in the cell cycle from the g1 to the s phase and from g2 through mitosis. homologues of p34(cdc2) have been found in all eukaryotes that have been investigated. levels of p34(cdc2)-like protein were studied by quantitative western blotting in developing cotyledons of daucus carota l. (carrot) seedlings, in expiants from the same seedlings transferred to tissueculture media with and without 2,4-dichlorophenoxyac ...199124186410
immunohistochemical localization of a glycoprotein, gp80, in the outermost layer of the developing endosperm of immature seeds of carrot.a glycoprotein (gp80) from the immature fruits of carrot (daucus carota l.) plants was purified through the sequential application of salt extraction, (nh4)2so4 precipitation, chromatography on columns of concanavalin a-sepharose, hydroxylapatite, and boronate, and electroelution, with subsequent sodium dodecylsulfate-polyacrylamide gel electrophoresis (sds-page). its apparent relative molecular mass (mr) was estimated to be 80 k by both sds-page and gel filtration at high ionic strength. the mr ...199124186342
chlorsulfuron resistance in daucus carota cell lines and plants:involvement of gene amplification.daucus carota l. cell lines stably resistant to the herbicide chlorsulfuron (cs) have been isolated according to a stepwise selection. studies carried out during different selection steps show that the specific activity of the target enzyme acetohydroxyacid synthase (ahas) increases along with cs resistance. southern hybridization analysis performed with abrassica napus ahas probe in a cs highly-resistant cell line reveals the presence of a greatly amplifiedecori fragment of genomic dna. this in ...199424186104

sodium-hydrogen exchanger inhibitory potential of malus domestica, musa × paradisiaca, daucus carota, and symphytum officinale.the involvement of sodium-hydrogen exchangers (nhe) has been described in the pathophysiology of diseases including ischemic heart and brain diseases, cardiomyopathy, congestive heart failure, epilepsy, dementia, and neuropathic pain. synthetic nhe inhibitors have not achieved much clinical success; therefore, plant-derived phytoconstituents may be explored as nhe inhibitors.201424184990
isozyme patterns in zygotic and somatic embryogenesis of carrot.isozyme patterns of carrot (daucus carota l.) zygotic embryos between the torpedo stage up to 5-day-old seedlings have been compared with those of the similar stages from the embryogenic cell suspension culture to the late somatic plantlet. somatic embryos blocked at the torpedo stage by β-cyclodextrine have also been analyzed. all these stages have been analyzed with respect to seven different enzyme systems: arylesterase, glucosephosphate isomerase, phosphogluconate dehydrogenase, alcohol dehy ...199624178665
biosynthesis of p-hydroxybenzoic acid in elicitor-treated carrot cell cultures.carrot (daucus carota l.) cells respond to treatment with fungal elicitors by synthesizing wallbound p-hydroxybenzoic acid (p-hba). the biosynthetic pathway to p-hba is still hypothetical. tracer experiments with l-phenylalanine indicate the involvement of the general phenylpropanoid pathway. 3,4 (methylenedioxy) innamic acid, an inhibitor of hydrocycinnamate coa ligase, inhibits the accumulation of anthocyanins in carrot, while it does not interfere with p-hba synthesis. thus p-hba biosynthesis ...199224178394
cdna cloning of an extracellular dermal glycoprotein of carrot and its expression in response to wounding.suspension-cultured cells of carrot (daucus carota l.) synthesize and secrete a glycoprotein that is normally found only in dermal tissues (epidermis, endodermis and periderm). this protein, previously called gp57, is now referred to as edgp (e xtracellular d ermal g lyco p rotein). we purified sufficient quantities of edgp to obtain amino-acid sequences on two internal tryptic peptides and screened a cdna library of young carrot roots with antiserum to edgp and with oligonucleotides correspondi ...199224178334

theoretical and experimental models of hormetic fusion tubulogenesis.hormetic morphogens are morphogens such as transforming growth factor beta (tgf-β) in mammals and auxin in plants that induce hormetic responses. for example, in vitro, tgf-β stimulates and inhibits cell proliferation at low and high concentrations respectively. i developed a model of hormetic morphogen gradient control of the morphogenesis of the fusion of bilateral aortic precursors (anlagen) that form the aorta during development; and validated the model with findings obtained by daucus carot ...201323930100
biosynthesis of carotenoids in carrot: an underground story comes to light.carrot (daucus carota) is a biannual plant that accumulates massive amounts of carotenoid pigments in the storage root. although the root of carrot plants was white before domestication, intensive breeding generated the currently known carotenoid-rich varieties, including the widely popular orange carrots that accumulate very high levels of the pro-vitamin a carotenoids β-carotene and, to a lower extent, α-carotene. recent studies have shown that the developmental program responsible for the acc ...201323876238
exploring insights for virulent gene inhibition of multidrug resistant salmonella typhi, vibrio cholerae, and staphylococcus areus by potential phytoligands via in silico screening.in our recent studies on prevalence of multidrug resistant pathogens in byramangala reservoir, karnataka, india, we identified salmonella typhi, staphylococcus aureus, and vibrio cholerae which had acquired multiple drug resistance (mdr) and emerged as superbugs. hence, there is a pressing demand to identify alternative therapeutic remedies. our study focused on the screening of herbal leads by structure-based virtual screening. the virulent gene products of these pathogens towards kanamycin(aph ...201423876154
dcsto: carrot stowaway-like elements are abundant, diverse, and polymorphic.we investigated nine families of stowaway-like miniature inverted-repeat transposable elements (mites) in the carrot genome, named dcsto1 to dcsto9. all of them were at-rich and shared a highly conserved 6 bp-long tir typical for stowaways. the copy number of dcsto1 elements was estimated as ca. 5,000 per diploid genome. we observed preference for clustered insertions of dcsto and other mites. distribution of dcsto1 hybridization signals revealed presence of dcsto1 clusters within euchromatic re ...201323775534
quality of carrots as affected by pre- and postharvest factors and processing.the aim of this review is to provide an update on factors contributing to quality of carrots, with special focus on the role of pre- and postharvest factors and processing. the genetic factor shows the highest impact on quality variables in carrots, causing a 7-11-fold difference between varieties in content of terpenes, β-carotene, magnesium, iron and phenolics as well as a 1-4-fold difference in falcarindiol, bitter taste and sweet taste. climate-related factors may cause a difference of up to ...201323744724
indirect effects on mutualisms: parasitism of bumble bees and pollination service to plants.researchers increasingly recognize the important role of mutualisms in structuring communities and view positive interactions in a community context rather than as simple pairwise interactions. indirect effects, such as those that predators have on lower trophic levels, are a key process in community ecology. however, such top-down indirect effects have rarely been extended to mutualisms. antagonists of one mutualist have the potential to negatively affect the second mutualist through negative e ...201323691664
isolation and characterization of a carrot nucleolar protein with structural and sequence similarity to the vertebrate pescadillo protein.the nuclear matrix is involved in many nuclear events, but its protein architecture in plants is still not fully understood. a cdna clone was isolated by immunoscreening with a monoclonal antibody raised against nuclear matrix proteins of daucus carota l. its deduced amino acid sequence showed about 40% identity with the pescadillo protein of zebrafish and humans. primary structure analysis of the protein revealed a pescadillo n-terminus domain, a single breast cancer c-terminal domain, two nucl ...201323683933
