Molecular mechanisms of cold stress response in cotton: Transcriptional reprogramming and genetic strategies for tolerance

Abstract

Cold stress has a huge impact on the growth and development of cotton, presenting a significant challenge to its productivity. Comprehending the complex molecular mechanisms that control the reaction to CS is necessary for developing tactics to improve cold tolerance in cotton. This review paper explores how cotton responds to cold stress by regulating gene expression, focusing on both activating and repressing specific genes. We investigate the essential roles that transcription factors and regulatory elements have in responding to cold stress and controlling gene expression to counteract the negative impacts of low temperatures. Through a comprehensive examination of new publications, we clarify the intricacies of transcriptional reprogramming induced by cold stress, emphasizing the connections between different regulatory elements and signaling pathways. Additionally, we investigate the consecutive effects of cold stress on cotton yield, highlighting the physiological and developmental disturbances resulting from extended periods of low temperatures. The knowledge obtained from this assessment allows for a more profound comprehension of the molecular mechanisms that regulate cold stress responses, suggesting potential paths for future research to enhance cold tolerance in cotton by utilizing targeted genetic modifications and biotechnological interventions.
