    Transcriptome analysis combined with metabolome analysis reveals the significant functions of CesA genes in cotton (Gossypium hirsutum) fiber length development


    BIOCELL, Vol.46, No.9, pp. 2133-2144, 2022, DOI:10.32604/biocell.2022.020512

    Abstract Cotton is widely distributed worldwide, and improving the quality of its fiber is one of the most important tasks in cotton breeding. Cotton fibers are primarily composed of cellulose, which is synthesized by CesA complexes (CSCs). However, the functions of CesA genes in cotton fiber development have not been comprehensively analysed. In this study, the cotton transcriptome and metabolome were used to investigate the function of CesA genes in fiber development. Finally, 321 metabolites were obtained, 84 of which were associated with the corresponding genes. Interestingly, a target gene named Gh_A08G144300, one of the CesA gene family members, More >

    NaOH/Urea Swelling Treatment and Hydrothermal Degradation of Waste Cotton Fiber

    Lixia Gao1, Sheng Shi1,2,*, Wensheng Hou1, Shuhua Wang1, Zhifeng Yan1, Chao Ge1

    Journal of Renewable Materials, Vol.8, No.6, pp. 703-713, 2020, DOI:10.32604/jrm.2020.09055

    Abstract In this study, waste cotton fabric was used as cellulose raw material and pretreated in aqueous NaOH/urea solution system to investigate the effect of NaOH/urea pretreatment solution on the hydrolysis of cotton fiber. The cotton fiber was pretreated with different conditions of aqueous NaOH/urea solution, and the pretreated cotton fiber was hydrolyzed under the same conditions as the original cotton fiber. The results of characterization analysis showed that water retention value of pretreated cotton fiber was higher than that of unpretreated sample. Moreover, the cotton fiber presented both a convoluted structure and a coarser surface,… More >

    Preparation and Characterization of Carbon Microspheres From Waste Cotton Textiles By Hydrothermal Carbonization

    Yongfang Zhang1,2, Wensheng Hou1, Hong Guo1, Sheng Shi1, Jinming Dai1,2,*

    Journal of Renewable Materials, Vol.7, No.12, pp. 1309-1319, 2019, DOI:10.32604/jrm.2019.07884

    Abstract Carbon microspheres were prepared from waste cotton fibers by hydrothermal carbonization (HTC) with the addition of copper sulphate in this work. The important influence factors, temperature, concentration of copper sulphate, resident time were explored here. The smooth and regular carbon microspheres could be formed at 330°C with 0.15 wt% copper sulphate after 6 h from waste cotton fibers. The crystal structures of cotton fibers were destructed in a short resident time with 0.15 wt% copper sulphate from SEM images and XRD patterns of solid products. This strategy provides a new, mild and efficient method to… More >
