Cotton is unusual among major crops in that large acreages are grown under both irrigated and rainfed conditions, making genotype x environment interactions of even greater importance than usual in designing crop-improvement strategies. We describe the impact of well-watered versus water-limited growth conditions on the genetic control of fiber quality, a complex suite of traits that collective...

correlated with soil organic matter, B, Cu, Fe, Mn, and Zn. Fiber quality was correlated with soil Mg, K, Cu, To maximize profitability, cotton (Gossypium hirsutum L.) producand As. Elms et al. (1997) reported that yield in an ers must attempt to control the quality of the crop while maximizing irrigated cotton field in Texas displayed spatial correlayield. The objective of this research was to...

Cotton is the most important textile crop in the world due to its cellulose-enriched fibers. Sucrose synthase genes (Sus) play pivotal roles in cotton fiber and seed development. To mine and pyramid more favorable alleles for cotton molecular breeding, single nucleotide polymorphisms (SNPs) of GhSus family genes were investigated across 277 upland cotton accessions by EcoTILLING. As a result, a...

Cotton fiber is renewable natural fiber source for textile. Improving fiber quality is an essential goal for cotton breeding project. In present study, F14 recombinant inbred line (RIL) population was backcrossed by the maternal parent to obtain a backcross (BC) population, derived from one Upland cotton hybrid. Three repetitive field trials were performed by randomized complete block design wi...

background: cotton is the main agricultural export product in benin. cotton dust is thus present in the air during the handling and processing of cotton. this dust contains a mixture of substances including ground up plant matter, fibres, bacteria, fungi, soil, pesticides, noncotton matter, and other contaminants. while cotton processing is decreasing in industrialized countries, it is increasi...

Cotton fiber is an ideal model to study cell elongation and cell wall construction in plants. During fiber development, some genes and proteins have been reported to be specifically or preferentially expressed. Mapping of them will reveal the genomic distribution of these genes, and will facilitate selection in cotton breeding. Based on previous reports, we designed 331 gene primers and 164 pro...

Fiber quality and yield improvement are crucial for cotton domestication and breeding. With the transformation in spinning techniques and multiplicity needs, the development of cotton fiber quality and yield is of great importance. A genetic map of 5178 Single Nucleotide Polymorphism (SNP) markers were generated using 277 F2:3 population, from an intra-specific cross between two upland cotton a...

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...

Ligon lintless mutant (li1li1) with super-short fibers (5-8 mm in length) and its wild type (Li1Li1) with normal fibers (30 mm in length) were used to study the function of xyloglucan endotransglycosylase/hydrolase (XTH) genes during fiber elongation in cotton. Wild-type cotton attained the fiber elongation stage earlier (5 days post-anthesis, DPA), than the Ligon lintless mutant (12 DPA)...

Background and Rationale The scientific infrastructure in support of cotton research and improvement took a ‘giant leap forward’ with the release of the first ‘gold-standard’ cotton reference genome sequence on 5 January 2012. Later in 2012, two independent publications (Paterson et al. 2012; Wang et al. 2012) provided initial descriptions of the basic genome of cotton, with one of these also r...
