Cotton (Gossypium spp.) is an important economic crop and there is obvious heterosis in cotton, fertility has played an important role in this heterosis. However, the genes that exhibit critical roles in anther development and fertility are not well understood. Here, we report an acyl-CoA N-acyltransferase (EC2.3; GhACNAT) that plays a key role in anther development and fertility. Suppression o...

It is still not clear whether differential response of Bt cotton and conventional non-Bt genotypes in terms growth, phenology yield ability are hypothetical or realistic. This study investigated the three hybrids comparison to their non-transgenic version (near-isogenic lines) along with two locally adapted for attributes, phenological characteristics rooting behavior. Therefore, experiments we...

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...

the identification of molecular markers linked to leaf curl virus (clcuv) disease resistance in cotton has the potential to improve both the efficiency and the efficacy of selection in cotton breeding programs. genetic analysis suggested that clcuv resistance is controlled by a single dominant gene. in this study, an interspecific f2 population derived from a cross of gossypium barbadense and g...

Arabinogalactan proteins (AGPs) are involved in many aspects of plant development. In this study, biochemical and genetic approaches demonstrated that AGPs are abundant in developing fibers and may be involved in fiber initiation and elongation. To further investigate the role of AGPs during fiber development, a fasciclin-like arabinogalactan protein gene (GhFLA1) was identified in cotton (Goss...

Kinetics and osmoregulation of cotton (Gossypium hirsutum L.) fiber growth (primarily extension) have been studied. Growth is dependent on turgor pressure in the fiber. It is inhibited when a decrease in the water potential of the culture medium due to an addition of Carbowax 6000, equals the turgor pressure of the fiber. Potassium and malate accumulate in the fiber and reach peak levels when t...

in order to study of combining ability and heterosis in cotton (gossypium hirsutum l.), six hopeful genotypes were crossed in a half-diallel scheme at gonbad research station. fifteen f1 hybrids along with six parents were grown in randomized complete block design with 3 replications, in 2004. combining ability estimates were calculated according to method 2, model 1 of griffing (1956a,b). rela...

Unexpected rainfall in harvest season has a detrimental effect on cotton lint color grade and germination rate to extent that economic losses occur for farmers, seed producers manufacturers. This study was conducted elucidate the effects of different amounts evaluate response cultivars 2014 2015. Bolls were exposed 0 (control), 20, 35, 65, 95 125 mm precipitation. The determined GSN-24, Claudia...

Aluminum-activated malate transporters (ALMT) are widely involved in plant growth and metabolic processes, including adaptation to acid soils, guard cell regulation, anion homeostasis, seed development. Although ALMT genes have been identified Arabidopsis, wheat, barley, Lotus japonicus, little is known about its presence Gossypium hirsutum L. In this study, gene recognition diploid tetraploid ...
