Cotton is under the constant threat of leaf curl virus, which is a major constraint for successful production of cotton in the Pakistan. A total of 3338 cotton genotypes belonging to different research stations were screened, but none were found to be resistant against the Burewala strain of cotton leaf curl virus (CLCuV). We explored the possibility of transferring virus-resistant genes f...

The responses of Aedes albopictus to sources of oviposition attractants and stimulants were evaluated with a behavioral bioassay in which females attracted to odorants emanating from water were trapped on screens coated with an adhesive. Gravid mosquitoes were attracted to volatiles from larval-rearing water and soil-contaminated cotton towels. Bacteria were isolated from these substrates and f...

The cotton intercropping experiment was conducted for the management of sucking pests, viz. leafhopper, Amrasca biguttula Ishida (Hemiptera: Cicadellidae); whitefly, Bemisia tabaci Gennadius Aleyrodidae) and thrips, Thrips Linderman (Thysanoptera: Thripidae) in desi cotton, Gossypium arborium. results study revealed that less mean population leafhopper nymphs, whitefly thrips adults recorded fr...

Mannose-specific Allium sativum leaf agglutinin encoding gene (ASAL) and herbicide tolerance gene (BAR) were introduced into an elite cotton inbred line (NC-601) employing Agrobacterium-mediated genetic transformation. Cotton transformants were produced from the phosphinothricin (PPT)-resistant shoots obtained after co-cultivation of mature embryos with the Agrobacterium strain EHA105 harbourin...

Cotton plants (Gossypium hirsutum L. cv 'McNair 220') at the third true leaf stage were exposed to ultraviolet radiation (UVR) for seven days and compared with controls that received only natural light. Light reflectance was spectrophotometrically measured over the 0.5-2.5 #m waveband on nonexcised leaves immediately after treatment and again seven days later. Spectral measurements were also co...

DNA γ is approximately half of the size of Begomovirus DNA. It encodes a γC1 gene that is conserved in position and size. This gene has the capacity to encode a 13 to 14 kDa protein comprising 118 amino acid residues. It has been shown earlier that γC1 protein is necessary for inducing symptoms of cotton leaf curl disease. The structure for γC1 (CLCuDγ01-Pakistan) is still unknown. Therefore, a...

A 2-year study was conducted to determine the relationships between plant canopy photosynthesis, canopy light interception, and plant productivity of cotton (Gossypium hirsutum L.) exhibiting differing leaf morphologies. The near-isogenic lines were from a single background (MD 65-11) and represented the leaf shapes Normal (small leaf lobing), Sub-Okra (intermediate leaf lobing), Okra (large le...

Digitalization of agriculture bring controllable industrial production and computer-aided design ideas into agriculture, NURBS curves and surfaces is described freedom of widely popular technology, CAD systems are widely used. Method can be easily applied to generate curves, surfaces with NURBS. In this paper, we have developed model of cotton organs using NURBS surface, present a introduction ...

BACKGROUND Cotton fiber, a natural fiber widely used in the textile industry, is differentiated from single cell of ovule epidermis. A large number of genes are believed to be involved in fiber formation, but so far only a few fiber genes have been isolated and functionally characterized in this developmental process. The Kinesin13 subfamily was found to play key roles during cell division and ...

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...
