New plant chemical identified for improving drought tolerance [Registered]

Researchers at the University of California, Riverside, have found a new drought-protecting chemical that shows high potential for becoming a powerful tool for crop protection against drought stress. Named “quinabactin” by the researchers, the chemical mimics a naturally occurring stress hormone in plants that helps the plants cope with drought conditions. Study results appear in the Proceedings of the National Academy of Sciences. All land plants have intricate water sensing and drought response systems that are tuned to maximize their fitness in the environments they live in. For example, plants in environments with low water grow slowly so that they…
