AN OVERVIEW OF DROUGHT TOLERANCE CHARACTERS IN COTTON PLANT: INCREASING CROP YIELD WITH EVERY WATER DROP

Abstract

Drought stress is a major factor limiting cotton productivity and quality worldwide. Understanding the physiological and inheritable mechanisms underpinning failure forbearance in cotton is essential for developing strategies to ameliorate cotton yield under water- limited conditions. This review paper summarizes recent advances in our understanding of the physiological and inheritable mechanisms contributing to failure forbearance in cotton. We punctuate cotton's crucial physiological and biochemical responses to failure stress, including changes in photosynthesis, water use effectiveness, and bibulous adaptation. We also review recent progress relating genes and molecular pathways involved in failure forbearance in cotton through transcriptomics and genome-wide association studies. Although significant progress has been made in relating genes and physiological mechanisms involved in cotton failure forbearance, important work remains to completely understand the complex relations between factory responses to  failure stress and the inheritable factors that govern these responses. This review paper underscores the need for continued exploration of the physiological and inheritable mechanisms underpinning cotton failure forbearance and the development of new strategies for perfecting cotton productivity and sustainability under water-limited conditions. Finally, we bandy implicit strategies for perfecting cotton failure forbearance through inheritable engineering, parentage, and agronomic practices. Overall, this review provides a comprehensive overview of the current knowledge on physiological and inheritable failure forbearance in cotton and identifies crucial exploration requirements and openings for unborn progress.
