Summary: In this study, it was found that the elongation of fiber cells in the Ligon lintless-2 (Li-2) cotton mutant is inhibited by siRNAs. This inhibition is caused by a large structural rearrangement at the end of chromosome D13, which leads to the production of self-complementary transcripts and generation of siRNAs. This finding reveals the regulatory mechanism of the Ran Binding Protein 1 family in cotton fiber growth.

Summary: The dynamic remodeling of the actin cytoskeleton plays a central role in cotton fiber elongation. In the Li-1 mutant, over-expression of GhACT17DM disrupts actin polymerization, affecting the establishment and dynamics of the actin cytoskeleton, resulting in defective fiber elongation and the overall dwarf and twisted phenotype.

Summary: The study identified three genes, GhRHD3-1, GhRHD4-1, and GhRSL4-1, which promote fiber elongation in cotton by regulating cell wall, photosynthesis, and oxidoreductase activity pathways. This research deepens our understanding of GhRHD genes in cotton and has implications for breeding better cotton varieties in the future.

Summary: The study identifies auxin response factor (ARF) genes in three cotton species, with GhARF2b playing a key role in cotton fiber development. It is shown that overexpression of GhARF2b inhibits fiber cell elongation but promotes initiation, while downregulation results in fewer but longer fibers. Additionally, GhARF2b is found to interact with GhHOX3 and repress its transcriptional activity on target genes.

Summary: Cotton fiber, a predominant plant textile globally, serves as a model for plant cell wall biosynthesis. The developmental process of cotton fiber involves multiple stages, including fiber initiation, elongation, cell wall formation, thickening, maturation, and cell death. The complex restructuring of genome-wide gene expression and physiological/biosynthetic processes during each stage contribute to the production of elongated cellulose fibers that are crucial for the cotton industry. This article provides an overview of this developmental process, highlighting its temporal and evolutionary dimensions, and proposes potential avenues for improving cotton as a crop plant.

Summary: The study reveals that GhPIPLC2D positively regulates cotton fiber elongation, and IP3 promotes fiber elongation by enhancing ethylene biosynthesis. External application of linolenic acid and phosphatidylinositol can improve the accumulation of IP3 and IP6, thereby affecting fiber length.

Summary: This study identified the function of a fiber elongation-specific TPX2 protein, GhMAP20L5, in cotton. Suppression of GhMAP20L5 gene expression significantly reduced fiber elongation rate, length, and lint percentage in cotton. GhMAP20L5 specifically interacted with tubulin GhTUB13 on the cytoskeleton.

Summary: This study investigates the characteristics of SCPLs in different cotton species and reveals that segmental duplication and whole genome duplication are the main reasons for the increase in the number of genes during cotton evolution. It also identifies Gh_SCPL genes that exhibit differential expression in particular tissues or response to environmental stimuli, providing a new measure for the in-depth characterization of selected genes of importance.

Summary: Phosphate fertilization has significant effects on cotton fiber length formation by increasing fiber sucrose, K+, and malate contents, enhancing fiber elongation development, and promoting sucrose metabolism, K+ transport, and malate synthesis. The positive effects of phosphate fertilization are more pronounced in the low-phosphate-sensitive variety compared to the low-phosphate-tolerant variety. The phosphorus content of the leaf subtending the cotton boll at 10 DPA is closely related to fiber elongation development and fiber length formation.

Summary: In this study, we propose MetaAc4C, an advanced deep learning model for accurate identification of N4-acetylcytidine (ac4C) sites using pre-trained BERT and various optimization techniques. By adapting generative adversarial networks to address data imbalance and augmenting training RNA samples, our model outperforms existing methods in terms of ACC, MCC, and AUROC.
