New potent analogues of plant hormone provide drought stress relief for crops

Amongst abiotic stresses, drought stress is one of the main sources of crop loss around the globe. One protection strategy is the development of chemicals that help crops cope with water deficiency. Using a natural plant hormone as their starting point, scientists identified several novel analogues that are highly effective against drought stress. As they report in the European Journal of Organic Chemistry, they also gained new insights into the structure-activity relationship of the hormone.
