agronomic and physiological traits and protein expression were compared between non-bt glandless upland cotton variety-zhong5629 and its bt-transgenic near-isogenic lines differing in cryiac gene. results showed that the bt isogenic line had higher plant height and rate of effective bolls, more internal bolls but lower yield, than the non-bt line. the bt isogenic line had lower chlorophyll cont...

TUDIES in quantitative inheritance are generally conducted as the analysis of the effects of groups of genes acting in concert to produce the character under consideration. Rarely can the number of loci involved be knc". It is thus of some interest when the number o i genes involved in the production of a character can be known through the use of a method (which allows for discrimination among ...

Mitochondria isolated from 2 strains of cotton plant hypocotyls (Gossypium hirsutum L. var. Rex smooth leaf and Rex glandless) were examined for their oxidative phosphorylation activities. Bovine serum albumin at a relatively high concentration was essential in the extraction medium for the isolation of oxidatively active mitochondria from both strains of cotton. Phosphorylation was obtained on...

Iqbal, M., M. NaeeM, U. azIz, J. afzal and M. alaM KhaN, 2014. an overview of cotton leaf curl virus disease, persistant challeng for cotton production. Bulg. J. Agric. Sci., 20: 405-415 Cotton leaf curl virus (ClCuV) disease is crucial threat for cotton production in Pakistan. ClCuV belongs to genus Begomovirus of Geminiviridae family and is transmitted by Bemisia tabaci. Drastic reduction in ...

BACKGROUND Upland cotton, Gossypium hirsutum L., is one of the world's most important economic crops. In the absence of the entire genomic sequence, a large number of expressed sequence tag (EST) resources of upland cotton have been generated and used in several studies. However, information about the flower development of this species is rare. METHODOLOGY/PRINCIPAL FINDINGS To clarify the mo...

Domesticated cotton species provide raw material for the majority of the world's textile industry. Two independent domestication events have been identified in allopolyploid cotton, one in Upland cotton (Gossypium hirsutum L.) and the other to Egyptian cotton (Gossypium barbadense L.). However, two diploid cotton species, Gossypium arboreum L. and Gossypium herbaceum L., have been cultivated fo...

Cytochrome P450 monooxygenases (P450s) are commonly involved in biosynthesis of endogenous compounds and catabolism of xenobiotics, and their activities rely on a partner enzyme, cytochrome P450 reductase (CPR, E.C.1.6.2.4). Two CPR cDNAs, GhCPR1 and GhCPR2, were isolated from cotton (Gossypium hirsutum). They are 71% identical to each other at the amino acid sequence level and belong to the Cl...

Membrane-bound fatty acid desaturases (FADs) are of great importance and play multiple roles in plant growth and development. In the present study, 39 full-length FAD genes, based on database searches, were identified in tetraploid upland cotton (Gossypium hirsutum L.) and were phylogenetically clustered into four subfamilies. Genomic localization revealed that 34 genes were mapped on 22 chromo...

The centromere is a repeat-rich structure essential for chromosome segregation; with the long-term aim of understanding centromere structure and function, we set out to identify cotton centromere sequences. To isolate centromere-associated sequences from cotton, (Gossypium hirsutum) we surveyed tandem and dispersed repetitive DNA in the genus. Centromere-associated elements in other plants incl...

Abstract Background Gossypium hirsutum L. ( cotton) is one of the most economically important crops in world due to its significant source fiber, feed, foodstuff, oil and biofuel products. However, utilization cottonseed was limited presence small darkly pigmented glands that contain large amounts gossypol, which toxic human beings non-ruminant animals. To date, some progress has been made pigm...
