Molecular evolutionary rate variation in Gossypium (cotton) was characterized using sequence data for 48 nuclear genes from both genomes of allotetraploid cotton, models of its diploid progenitors, and an outgroup. Substitution rates varied widely among the 48 genes, with silent and replacement substitution levels varying from 0.018 to 0.162 and from 0.000 to 0.073, respectively, in comparisons...
Genome sizes vary by several orders of magnitude, driven by mechanisms such as illegitimate recombination and transposable element proliferation. Prior analysis of the CesA region in two cotton genomes that diverged 5-10 million years ago (Ma), and acquired a twofold difference in genome size, revealed extensive local conservation of genic and intergenic regions, with no evidence of the global ...
New World tetraploid cottons (Gossypium spp.) originated through hybridization of ancestral diploid species that presently have allopatric ranges in Asia-Africa (the A genome) and the New World tropics and subtropics (the D genome). Despite intensive study, the identity of the parental diploids and the antiquity of polyploidization remain unresolved. In this study, variation in the maternally i...
We investigated the locations of 5S and 45S rDNA in Gossypium diploid A, B, D, E, F, G genomes and tetraploid genome (AD) using multi-probe fluorescent in situ hybridization (FISH) for evolution analysis in Gossypium genus. The rDNA numbers and sizes, and synteny relationships between 5S and 45S were revealed using 5S and 45S as double-probe for all species, and the rDNA-bearing chromosomes wer...
Fusarium semitectum was found to be the major seed colonizing fungus in the commercial acid delinted cotton (Gossypium hirsutum) seed lots. There was no correlation, however, between its incidence and seedling emergence and disease symptoms on the emerged seedlings in autoclaved sand. Inoculation technique simulating internally seedborne nature of the fungus showed that the observed non-correla...
در این تحقیق امکان استفاده از ساقه پنبه (gossypium hirsutum l) در ساخت تخته خرده-چوب در دو مرحله مجزا مورد بررسی قرار گرفت. در مرحله اول ذرات پنبه به صورت مخلوط با خرده-چوب های صنوبر (populus nigra) برای ساخت تخته خرده چوب سه لایه مورد استفاده قرار گرفت.
We employ a detailed restriction fragment length polymorphism (RFLP) map to investigate chromosome organization and evolution in cotton, a disomic polyploid. About 46.2% of nuclear DNA probes detect RFLPs distinguishing Gossypium hirsutum and Gossypium barbadense; and 705 RFLP loci are assembled into 41 linkage groups and 4675 cM. The subgenomic origin (A vs. D) of most, and chromosomal identit...
The data presented here delineates the glycoproteome component in the elongating cotton fiber cells attained using complementary proteomic approaches followed by protein and N-linked glycosylation site identification (Kumar et al., 2013) [1]. Utilizing species specific protein sequence databases in proteomic approaches often leads to additional information that may not be obtained using cross-s...
