    Abstract Upland cotton (Gossypium hirsutum) is the most important plant producing natural fibers for the textile industry. In this study, we first investigated the phenotypic variation of seven agronomic traits of 273 diverse cotton accessions in the years 2017 and 2018, which were from 18 geographical regions. We found large variations among the traits in different geographical regions and only half of the traits in either years 2017 or 2018 followed a normal distribution. We then genotyped the collection with 81,612 high quality SNPs. Phylogenetic tree and population structure revealed a diverse genetic structure of the core collection, and geographical diversification… More >

    Md. Shohan Parvez1,2, Md. Mustafizur Rahman1,3,*, Mahendran Samykano1, Mohammad Yeakub Ali4

    Energy Engineering, Vol.121, No.1, pp. 1-12, 2024, DOI:10.32604/ee.2023.027472

    Abstract With the exponential development in wearable electronics, a significant paradigm shift is observed from rigid electronics to flexible wearable devices. Polyaniline (PANI) is considered as a dominant material in this sector, as it is endowed with the optical properties of both metal and semiconductors. However, its widespread application got delineated because of its irregular rigid form, level of conductivity, and precise choice of solvents. Incorporating PANI in textile materials can generate promising functionality for wearable applications. This research work employed a straightforward in-situ chemical oxidative polymerization to synthesize PANI on Cotton fabric surfaces with varying dopant (HCl) concentrations. Pre-treatment using… More >

    Yueying Liu#, Yuqing Wang#, Lijiao Gu*

    Phyton-International Journal of Experimental Botany, Vol.92, No.11, pp. 2937-2946, 2023, DOI:10.32604/phyton.2023.043306

    Abstract WRKY transcription factors play important roles in plant growth, development, and stress responses. Our previous research has shown that the GhWRKY91 gene can delay age-, abscisic acid (ABA)-, and drought-induced leaf senescence when overexpressed in transgenic Arabidopsis plants. To explore in more depth the biological functions of the GhWRKY91 gene, we further observed the root growth of overexpressing transgenic Arabidopsis thaliana under ABA and drought treatment. In this study, we transplanted the germinated seeds of wild-type (WT) and three transgenic lines (OE-12, OE-13 and OE-20) to 1/2 MS solid medium containing ABA and different concentrations of mannitol (simulated drought treatment)… More >

    Mehwish Zafar1, Javeria Amin2, Muhammad Sharif1, Muhammad Almas Anjum3, Seifedine Kadry4,5,6, Jungeun Kim7,*

    CMC-Computers, Materials & Continua, Vol.76, No.3, pp. 2779-2793, 2023, DOI:10.32604/cmc.2023.035860

    Abstract Worldwide cotton is the most profitable cash crop. Each year the production of this crop suffers because of several diseases. At an early stage, computerized methods are used for disease detection that may reduce the loss in the production of cotton. Although several methods are proposed for the detection of cotton diseases, however, still there are limitations because of low-quality images, size, shape, variations in orientation, and complex background. Due to these factors, there is a need for novel methods for features extraction/selection for the accurate cotton disease classification. Therefore in this research, an optimized features fusion-based model is proposed,… More >

    Ming Dong#, Yan Wang#, Shulin Wang, Guoyi Feng, Qian Zhang, Yongzeng Lin, Qinglong Liang, Yongqiang Wang*, Hong Qi*

    Phyton-International Journal of Experimental Botany, Vol.92, No.10, pp. 2841-2860, 2023, DOI:10.32604/phyton.2023.030465

    Abstract Restructuring tilth layers (RTL) is a tillage method that exchanges the 0–20 and 20–40 cm soil layers that can be applied during cotton cultivation to increase cotton yield, eliminate weeds and alleviate severe disease, including Verticillium wilt. However, the mechanism by which RTL inhibits Verticillium wilt is unclear. Therefore, we investigated the distribution of microbial communities after rotary tillage (CK) and RTL treatments to identify the reasons for the reduction of Verticillium wilt in cotton fields subjected to RTL. Illumina high-throughput sequencing was used to sequence the bacterial and fungal genes. The disease incidence and severity of Verticillium wilt decreased… More >

    GhSCL4 Acts as a Positive Regulator in Both Transgenic Arabidopsis and Cotton during Salt Stress

    Yanyan Zhao1,*, Yanpeng Ding2, Bailin Duan1, Qingzhou Xie1

    Phyton-International Journal of Experimental Botany, Vol.92, No.1, pp. 1-15, 2023, DOI:10.32604/phyton.2022.022384

    Abstract GRAS transcription factors play important roles in plant abiotic stress response, but their characteristics and functions in cotton have not been fully investigated. A cotton SCL4/7 subgroup gene in the GRAS family, GhSCL4, was found to be induced by NaCl treatments. Nuclear localization and transactivation activity of GhSCL4 indicate its potential role in transcriptional regulation. Transgenic Arabidopsis thaliana over-expressing GhSCL4 showed enhanced resistance to salt and osmotic stress. What’s more, the transcript levels of salt stress-induced genes (AtNHX1 and AtSOS1) and oxidation-related genes (AtAPX3 and AtCSD2) were more highly induced in the GhSCL4 over-expression lines than in wild type after… More >

    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, was closely… More >
