Brassinosteroids in Plant Developmental Biology and Stress Tolerance provides insights into understanding the mechanisms of Brassinosteroid-regulated plant developmental biology and stress tolerance covering various biochemical, physiological, genetic and molecular studies.    As unprecedented climate change poses a serious threat to global food security by intensifying environmental stresses, studies reveal that Brassinosteroids (BRs) could not only protect plants from stresses to ensure food security, but could also reduce toxic compounds in edible plant parts for assuring food safety. Therefore, utilization of BRs in modern agriculture will be of great significance in the context of global climate change.    This book also highlights key information for developing eco-friendly growth regulators and understanding the importance of brassinosteroids in safe food production.
