ABSTRACT
There are a variety of biotic and abiotic factors that contribute to losses in agricultural food productivity, and it is increasingly essential to reduce these losses to increase food production to accommodate needs of an already overcrowded population in India. Further, it is predicted that crop yields will decline up to 25% by 2050 if these influencers are not managed adequately. The country is already struggling to feed its people and faces significant challenges in increasing its food production to 400 million tons by 2030. India’s farmers must increase their food production by 50% by 2025 in order to ensure food security for this rapidly increasing population. Abiotic stress management using plant hormones has attracted significant interest in recent years. In the process of acclimatizing to various abiotic and biotic stresses, plants undergo multiple changes that are controlled by phytohormones at various levels, including biochemical, physiological, and molecular levels. Therefore, administering phytohormones exogenously may be a good alternative approach for plants that are resistant to this already changing environment. It is most widely known that brassinosteroids (BRs) hormone plays an eminent role in the plant life. Over the past 30 years, scientists have concentrated more on biosynthesis, distribution, and signaling to comprehend its function. It is now known that plants respond to environmental stimuli such as drought, salt, and extreme temperatures through the BR cascade, a class of molecules that play crucial roles in growth and development. BRs were initially identified for their role in cell elongation. This chapter discusses recent advancements in the ability of BRs to address abiotic stress in commercially important food crops.
