Research reveals secret of drought resistance

A team of biologists in California led by researchers at The Scripps Research Institute and the University of California (UC), San Diego has solved the structure of a critical molecule that helps plants survive during droughts. Understanding the inner workings of this molecule may help scientists design new ways to protect crops against prolonged dry periods, potentially improving crop yields worldwide, aiding biofuels production on marginal lands and mitigating drought's human and economic costs.
The findings were described in the journal Science Express, an advance online issue of the journal Science, Oct. 22.
The newly solved structure shows a three-dimensional representation of a critical plant hormone called abscisic acid, attached to its "target" protein called PYR1. Abscisic acid is key to many plant processes, including to survival tactics in challenging environmental conditions.
