How crops survive drought

Breakthrough research done earlier this year by a plant cell biologist has greatly accelerated scientists' knowledge on how plants and crops can survive difficult environmental conditions like drought. In drought conditions certain receptor proteins in plants perceive ABA, causing them to inhibit an enzyme called a phosphatase. The receptor protein is at the top of a signaling pathway in plants, functioning like a boss relaying orders to the team below that then executes particular decisions in the cell. Now recent published studies show how those orders are relayed at the molecular level.
