A comprehensive overview of cotton genomics, biotechnology and molecular biological studies

Comparative Transcriptomic Analysis of Gossypium hirsutum Fiber Development in Mutant Materials (xin w 139) Provides New Insights into Cotton Fiber Development

“…Cotton is a widely planted natural fiber crop worldwide, and improving cotton fiber quality has long been a research hotspot. The creation and breeding of germplasm resources with high yields and excellent fiber quality has also become a long-term research direction and goal for cotton breeders [ 1 , 2 ]. Cotton fibers develop from single cells of the ovule epidermis, and their development involves a complex process consisting of four consecutive but overlapping stages.…”

“…We detected a decrease in the fiber length, strength and single-boll weight of xin w 139 , mainly due to its development after 20 DPA. The 20–40 DPA period mainly encompasses the secondary wall synthesis stage of cotton fiber development, during which a large amount of cellulose is synthesized, making this the key period for improving fiber strength [ 1 ]. We found that the fiber length of xin w 139 was also reduced by approximately 40% compared to that of Xin W 139, indicating that fiber elongation was not completed at 20 DPA.…”

“…Over the years, there has been a strong focus on enhancing the quality of cotton fibers, which has emerged as a prominent area of research. Cotton breeders have been actively engaged in developing and cultivating germplasm resources that not only yield high quantities but also possess exceptional fiber quality [ 1 , 2 ]. Cotton fiber development is a complex process that occurs in four consecutive and overlapping stages.…”

“…Cotton fibers develop from ovule epidermal cells, and improving cotton fiber quality has long been a research hotspot. The creation and breeding of germplasm resources with high yields and excellent fiber quality has also become a long-term research direction and goal for cotton breeders [ 1 , 2 ]. Studying the regulatory mechanism of cotton fiber cell elongation and secondary wall development is highly important for improving the cotton yield and fiber quality.…”

A cotton APS REDUCTASE represses root hair elongation via sulfur assimilation and hydrogen peroxide‐mediated cell wall damage

“…Cotton fibers and trichomes on the seed coat are single cells that are important sources of natural fiber for the textile industry (Rinehart et al 1996). Some key factors and regulatory networks are shared in the development of fiber cells and root hairs, suggesting that there are conserved mechanisms in the development of these two types of cells (Wang et al 2019, Wen et al 2023). Sulfur is an essential macronutrient very important for the growth and function of plants (Zenda et al 2021).…”
