| distinguishing the biomass allocation variance resulting from ontogenetic drift or acclimation to soil texture. | in resource-poor environments, adjustment in plant biomass allocation implies a complex interplay between environmental signals and plant development rather than a delay in plant development alone. to understand how environmental factors influence biomass allocation or the developing phenotype, it is necessary to distinguish the biomass allocations resulting from environmental gradients or ontogenetic drift. here, we compared the development trajectories of cotton plants (gossypium herbaceum l.) ... | 2012 | 22911802 |
| physiological performance and differential expression profiling of genes associated with drought tolerance in contrasting varieties of two gossypium species. | cotton is mostly cultivated under rain-fed conditions in india, thus faces frequent drought conditions during its life cycle. drought being a major stress factor responsible for yield penalty, there has always been a high priority to generate knowledge on adaptation and tolerance of cotton. in the present study, four cotton varieties, jkc-770 and kc-2 (gossypium hirsutum), and jkc-717 and rahs-187(gossypium herbaceum), were imposed to drought. under drought condition, differential changes in phy ... | 2015 | 25149149 |
| identification of centromeric regions on the linkage map of cotton using centromere-related repeats. | centromere usually contains high-copy-number retrotransposons and satellite repeats, which are difficult to map, clone and sequence. currently, very little is known about the centromere in cotton. here, we sequenced a bacterial artificial chromosome (bac) mapping to the centromeric region and predicted four long-terminal-repeat (ltr) retrotransposons. they were located in the heterochromatic centromeric regions of all 52 pachytene chromosomes in gossypium hirsutum. fiber-fish mapping revealed th ... | 2014 | 25238895 |
