Cotton fiber development is a complex process regulated by multiple networks that involve various transcription factors (TFs). Recent studies (2020-2025) have elucidated the roles of TFs through silencing and overexpression experiments in cotton plants. We conducted a literature search in NCBI using the keywords ‘transcription factor, fiber elongation, cotton plant’ to identify relevant studies. This review focuses on studies published between 2020 and 2025 that were selected for review. We discussed various TFs and molecular mechanisms leading to altered fiber length. The research works included various analyses of transcription factors, genes, proteins, and metabolites as well as fiber quality results. The reviewed data highlight the complexity of fiber development networks, which involve extensive crosstalk among regulatory pathways. Despite the complexity, many novel TFs, modules, and tandems that participate in fiber elongation have been found. Their positive or negative regulatory roles in fiber formation stages promote a more profound understanding of fiber initiation and elongation.
