Cotton is an important economic crop, used mainly for the production of textile fiber. Using a space mutation breeding technique, a novel photosensitive genetic male sterile mutant CCRI9106 was isolated from the wild-type upland cotton cultivar CCRI040029. To study the male sterile mechanisms of CCRI9106, histological and iTRAQ-facilitated proteomic analyses of anthers were performed. This data...

A molecular analysis of class III peroxidases from cotton (Gossypium hirsutum L.) was undertaken using the sequence of 12 genes available in databanks. Sequence comparison, phylogenetical analysis, and investigation of expression in organs were performed to characterize this group of peroxidases in cotton. All 12 genes possess the characteristics of class III peroxidases, including three conser...

Cotton leaf curl disease is the major biotic constraint to cotton production in Pakistan and India.The disease causes unusual symptoms that include vein swelling, enations and the formation of leaf-like outgrowths. Cotton production during the 1990s was severely curtailed by CLCuD across the sub-continent. This stimulated interest in determining the aetiology and generating resistant varieties....

Cellulose deposition in developing cotton fibers has been studied previously with analytical techniques, such as Fourier transform infrared spectroscopy (FTIR), High-performance liquid chromatography (HPLC) and Thermogravimetric analysis (TGA). Recent technological developments in instrumentation have made Raman microscopy emerge as an extraordinary analytical tool in biological and plant resea...

The impact of nitrogen fertilization on cotton plants, Gossypium hirsutum L., silverleaf whitefly, Bemisia argentifolii Bellows & Perring, population dynamics and honeydew production were investigated in the field at Riverside, California, USA. Treatments were soil applications of 0, 112, 168 and 224 kg nitrogen per hectare, and a soil application of 112 kg of nitrogen plus a foliar application...

Water is crucial for crop growth and productivity. Cotton metabolism and yield are compromised under drought conditions, especially at flowering stage. Differences in drought tolerance exist among cultivars but the metabolic reasons for this that could be used to find traits for enhancing drought tolerance have not been clearly elucidated. Under drought stress, osmotic adjustment occurs in plan...

Functional genomics has transformed from futuristic concept to well-established scientific discipline during the last decade. Cotton functional genomics promise to enhance the understanding of fundamental plant biology to systematically exploit genetic resources for the improvement of cotton fibre quality and yield, as well as utilization of genetic information for germplasm improvement. Howeve...

The two most economically important plant-parasitic nematodes infesting cotton (Gossypium hirsutum) in the United States are the root-knot (Meloidogyne incognita) and the reniform (Rotylenchulus reniformis) nematode. The common means of managing these pests is use of in-furrow or seed-treatment nematicides, or by rotation with non-host crops or resistant cultivars of crops grown in rotation. Un...

in order to study the effects of mechanical and chemical methods of weed control and their interaction on cotton (cv. varamin) an experiment was conducted in agricultural research field, the university of birjand during 2008 growing season using a randomize complete block design with 12 treatments and 4 replications. treatments were: trefelan (trifluralin 48% ec) 960cc ai ha-1 (pre-plant), sona...
