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)...

Abstract. In the textile industry, different types of foreign fibers may be mixed in cotton, and the foreign fibers seriously affect the quality of cotton products. The step of image segmentation is of vital importance in the process of the foreign fibers identification, which is, in the same way, the foundation for cotton foreign fiber automated inspection. This paper presents a new approach ...

Jute is a strong, stiff, natural fiber. When blended with cotton it makes a sturdy but prickly fabric due to protruding surface jute fibers. Samples of jute-cotton blended fabric were treated with commercial cellulases, xylanases and pectinases individually and in combination at various concentrations in order to smooth and soften the fabric. Enzyme treatment was carried out at 50°C in the pres...

Cellulose synthase catalytic subunits (CesAs) are the catalytic sites within a multisubunit complex for cellulose biosynthesis in plants. CesAs have been extensively studied in diploid plants, but are not well characterized in polyploid plants. Gossypium hirsutum is an allotetraploid cotton species producing over 90% of the world's cotton fibers. Although G. hirsutum CesAs (GhCesAs) are respons...

OBJECTIVE To microbiologically evaluate the efficacy of cotton and polytetrafluoroethylene (PTFE) tape used as spacer materials. METHOD AND MATERIALS Twenty-six extracted human molars were restored using either cotton or PTFE tape as spacers under a standardized provisional restorative material (Cavit). The teeth were incubated for 7 days in a culture of Streptococcus gordonii or in liquid me...

A cotton fiber cDNA and its genomic sequences encoding an A-type cyclin-dependent kinase (GhCDKA) were cloned and characterized. The encoded GhCDKA protein contains the conserved cyclin-binding, ATP binding, and catalytic domains. Northern blot and RT-PCR analysis revealed that the GhCDKA transcript was high in 5-10 DPA fibers, moderate in 15 and 20 DPA fibers and roots, and low in flowers and ...

The surface characteristics of cotton fibers were investigated by a microelectrophoretic t echnique. Samples of dewaxed cotton, cotton which had been depectinized by treatment with a boiling I-percent solution of sodium hydroxide for various lengths of time, and pectic substance from cotton gave widely different pH-mobility curves. The curve for pectic subst ance is characteristic of a highly a...

Cotton (Gossypium hirsutum L.) fibers are single highly elongated cells derived from the outer epidermis of ovules. A large number of genes are required for fiber differentiation and development, but so far, little is known about how these genes control and regulate the process of fiber development. Here we examine the role of the cotton-fiber-specific R2R3 MYB gene GhMYB109 in cotton fiber dev...
