The Tomato DELLA Protein PROCERA Acts in Guard Cells to Promote Stomatal Closure.

The Plant cell - 1 Dec 2017

Abstract excerpt

Plants employ stomatal closure and reduced growth to avoid water deficiency damage. Reduced levels of the growth-promoting hormone gibberellin (GA) lead to increased tolerance to water deficit, but the underlying mechanism is unknown. Here, we show that the tomato (Solanum lycopersicum) DELLA protein PROCERA (PRO), a negative regulator of GA signaling, acts in guard cells to promote stomatal closure and reduce...
