in order to correlation diversity assessment among the quantitative and fiber quality traits, five cultivars of tetraploid cotton (g. hirsutum) cultivars were evaluated at varamin region in 2009. in this study the populations of the cultivar lines were planted near together and 100 lines randomly were selected at the end of the season followed by measuring seed cotton yield and quantitative and...

In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...

Cotton (Gossypium spp.) fiber cells are seed trichomes derived from the epidermal layer of the cotton seed coat. The molecular components responsible for regulating fiber cell differentiation have not been fully elucidated. A cotton PROTODERMAL FACTOR1 gene (GbPDF1) was found to be expressed preferentially during fiber initiation and early elongation, with highest accumulation in fiber cells 5 ...

Cotton fiber is an important natural textile fiber due to its exceptional length and thickness. These properties arise largely through primary and secondary cell wall synthesis. The cotton fiber of commerce is a cellulosic secondary wall surrounded by a thin cuticulated primary wall, but there were only sparse details available about the polysaccharides in the fiber cell wall of any cotton spec...

This paper is of some historical interest. It describes an investigation to determine whether byssinosis occurred among workers in the waste cotton industry. It was undertaken in 1950 at the instigation of the Minister of National Insurance. The materials used in the industry were (i) cotton that had been previously spun, and (2) waste material discarded during the preparations for spinning hig...

Cotton fibers are single-celled extensions of the seed epidermis. They can be isolated in pure form as they undergo staged differentiation including primary cell wall synthesis during elongation and nearly pure cellulose synthesis during secondary wall thickening. This combination of features supports clear interpretation of data about cell walls and cellulose synthesis in the context of high t...

Unlike other major crops in which seeds provide most of the economic value, cotton seed is largely a by-product of more valuable fiber production and represents only approximately 15% of the farm gate value of the cotton crop. A cotton plant normally produces about 1.6 kg of seed for every kg of lint. Following ginning to remove the lint fiber, fuzzy cotton seed is either used directly as anima...

The single-celled cotton (Gossypium hirsutum) fiber provides an excellent model to investigate how human selection affects phenotypic evolution. To gain insight into the evolutionary genomics of cotton domestication, we conducted comparative transcriptome profiling of developing cotton fibers using RNA-Seq. Analysis of single-celled fiber transcriptomes from four wild and five domesticated acce...

Cotton fiber is an economically important seed trichome and the world's leading natural fiber used in the manufacture of textiles. As a step toward elucidating the genomic organization and distribution of gene networks responsible for cotton fiber development, we investigated the distribution of fiber genes in the cotton genome. Results revealed the presence of gene-rich islands for fiber genes...
