Cotton fibers are differentiated epidermal cells originating from the outer integuments of the ovule. To identify genes involved in cotton fiber elongation, we performed subtractive PCR using cDNA prepared from 10 days post anthesis (d.p.a.) wild-type cotton fiber as tester and cDNA from a fuzzless-lintless (fl) mutant as driver. We recovered 280 independent cDNA fragments including most of the...

From manufacturing to disposal, the textile industry faces multiple challenges achieve sustainability and reduce its environmental impact. This work investigates properties composition of cellulose nanocrystals (CNCs) extracted from clothing waste made cotton fibers. We isolated CNCs cotton, polyester/cotton, acrylic/cotton fabrics through acid hydrolysis with sulfuric acid. A yield 51–62 wt % ...

World textile fiber demand was 89.8 million tons in 2015 and is expected to grow to 93.7 million tons in 2016. Global demand for textile fibers is driven by population growth and by economic activity resulting in increasing wealth, particularly in emerging economies. While this overall trend is consistent across most major fibers, there are substantial disparities in the demand patterns of natu...

In order to improve the recognition accuracy of seed cotton foreign fibers, a study on identification method in hyper-spectral images based on Minimum Noise Fraction (MNF) was proposed ,which was applied to feature extraction to reduce the dimension of hyper-spectral images. This method reduced the numbers of hyper-spectral data, lessened the images noise to the minimum , but also decreased the...

As high-strength cotton fibers are critical components of high quality cotton, developing cotton cultivars with high-strength fibers as well as high yield is a top priority for cotton development. Recently, chromosome segment substitution lines (CSSLs) have been developed from high-yield Upland cotton (Gossypium hirsutum) crossed with high-quality Sea Island cotton (G. barbadense). Here, we con...

Green cotton (Gossypium hirsutum L.) fibers were shown by electron microscopy to have numerous thin concentric rings around the lumen of the cell. These rings possessed a lamellar fine structure characteristic of suberin. LiA1D(4) depolymerization and gas chromatography-mass spectrometry analysis showed the presence of a suberin polymer in the green cotton with the major aliphatic monomers bein...

Cotton (Gossypium spp.) fibers are single-cell trichomes that arise from the outer epidermal layer of seed coat. Here, we isolated a R3-MYB gene GhCPC, identified by cDNA microarray analysis. The only conserved R3 motif and different expression between TM-1 and fuzzless-lintless mutants suggested that it might be a negative regulator in fiber development. Transgenic evidence showed that GhCPC o...

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 ...

As a fundamental step towards creating a new class of cellulose engineering materials, the proposed research investigated swelling and dissolution of cellulose in NaOH aqueous solvent systems (NaOH/H2O, NaOH/thiourea/H2O and NaOH/thiourea/urea/H2O). The dependence of swelling and dissolution behavior of cellulose fibers on the quality of the solvent was investigated in detail. For the two cellu...

Arginase is the only enzyme capable of producing urea in plants. This enzyme also contributes to many important biological functions during plant growth and development, such as seed development, root development and plant nitrogen using. The unique rice arginase gene OsARG is known to affect nitrogen use efficiency and is also associated with higher yields in rice. In this study, we transforme...
