Macroand crystalline structure, as well as chemical composition of fibers related to various types and sorts of Israeli cottons, both white and naturally colored, were investigated. The differences in structural parameters and chemical compositions of the cotton fibers were evaluated. Samples of cotton of the “Pima”-type had long, thin and strong fibers with highly ordered supermolecular struct...

cotton (gossypium hirsutum l.) as a unique crop in natural fiber production has an important role in texture industry. it has also a large share in oil production for human nutrition and as a protein concentrate for animal feeding. therefore, cotton role in job opportunities in agriculture, industry and business divisions are undeniable. in order to determine the share of each direct and indire...

In this paper, the ultraviolet protection factor (UPF) of plain knitted fabrics made from 20Ne cotton yarns, Coolmax yarn and their combinations in wet, relaxed and stretched states were studied. According to the fiber composition, fabric samples are divided into three groups including Group I (single cotton yarn), Group II (cotton/cotton combination) and Group III (Coolmax/cotton combination) ...

Sucrose (Suc) synthase (Sus) is the major enzyme of Suc breakdown for cellulose biosynthesis in cotton (Gossypium hirsutum) fiber, an important source of fiber for the textile industry. This study examines the tissue-specific expression, relative abundance, and temporal expression of various Sus transcripts and proteins present in cotton. A novel isoform of Sus (SusC) is identified that is expr...

Using rapid amplification of cDNA ends (RACE)-PCR, two full-length cDNAs encoding putative seven-transmembrane receptors (designated Gh7TMpR1 and Gh7TMpR2) were cloned from cotton plants. Southern blot and an ApaL1 restriction site polymorphism analyses revealed that Gh7TMpR1 was derived from the ancestral A diploid genome, while Gh7TMpR2 was from the D subgenome. Northern blot hybridization in...

The distinct stages of cotton fiber development and maturation serve as a single-celled model for studying the molecular mechanisms of plant cell elongation, cell wall development and cellulose biosynthesis. However, this model system of plant cell development is compromised for proteomic studies due to a lack of an efficient protein extraction method during the later stages of fiber developmen...

Field trials were conducted during 1990 to evaluate the effects of preplant soil fumigation with 1,3-dichloropropene (1,3-D) on yield and fiber quality of furrow-irrigated cotton cultivars subjected to high population densities of Meloidogyne incognita. We measured the responses of eight upland cotton cultivars with different levels of root-knot nematode resistance and compared the responses of...

Cotton is the bulkiest sink of natural textile fiber and a main oilseed crop, with extensive scientific, environmental, and socio-economic footsteps. Cotton fiber is a highly elongated seed hair with a secondary wall composed of almost pure cellulose. Development of cotton fibers is positively affected by a number of phytohormones including auxin, gibberellins and brassinosteroids (BRs) [1,2]. ...

Gutierrez et al., 2002; Lu and Myers, 2002). Genetic distances could be as low as 1 to 3%. Research in AustraGenetic diversity in modern upland cotton cultivars (Gossypium lia, China, and Pakistan obtained similar results (Multani hirsutum L.) is thought to be narrow, thus limiting genetic advance. Robust information on the genetic relatedness among currently grown and Lyon, 1995; Zuo et al., 2...
