Acetic-acid-induced jasmonate signaling in root enhances drought avoidance in rice
Abstract Conferring drought resistant traits to crops is one of the major aims of current breeding programs in response to global climate changes. We previously showed that exogenous application of acetic acid to roots of various plants could induce increased survivability under subsequent drought s...

Abstract Conferring drought resistant traits to crops is one of the major aims of current breeding programs in response to global climate changes.

In this study, we show that rice rapidly induces jasmonate signaling upon application of acetic acid, resulting in physiological changes similar to those seen under drought.
