In this study, 40 phospholipase D (PLD) genes were identified from allotetraploid cotton Gossypium hirsutum, and 20 PLD genes were examined in diploid cotton Gossypium raimondii. Combining with 19 previously identified Gossypium arboreum PLD genes, a comparative analysis was performed among the PLD gene families among allotetraploid and two diploid cottons. Based on the orthologous relationship...
Polyploid formation and processes that create partial genomic duplication generate redundant genomic information, whose fate is of particular interest to evolutionary biologists. Different processes can lead to diversification among duplicate genes, which may be counterbalanced by mechanisms that retard divergence, including gene conversion via nonreciprocal homoeologous exchange. Here, we used...
Low levels of nucleotide diversity at homoeologous Adh loci in allotetraploid cotton (Gossypium L.).
Levels of genetic diversity within and among populations and species are shaped by both external (population-level) and internal (genomic and genic) evolutionary forces. To address the effect of internal pressures, we estimated nucleotide diversity for a pair of homoeologous Adh loci in an allotetraploid species, Gossypium hirsutum. These data represent the first such estimates for a pair of ho...
Genome-Wide Mining, Characterization, and Development of Microsatellite Markers in Gossypium Species
Although much research has been conducted to characterize microsatellites and develop markers, the distribution of microsatellites remains ambiguous and the use of microsatellite markers in genomic studies and marker-assisted selection is limited. To identify microsatellites for cotton research, we mined 100,290, 83,160, and 56,937 microsatellites with frequencies of 41.2, 49.1, and 74.8 micros...
an ex-situ experiment to assess the metal extractive potential of fourteen agriculture plants (vigna unguiculata, gossypium hirsutum, jatropha curcas, etc.) was conducted on magnesite mines which had above permissible levels of cadmium and lead. there was no much difference in the total chlorophyll a and b, carbohydrate and protein contents in the plants grown in the mining soil and adjacent co...
