Here we report that the external application of acetate enhances the drought tolerance in all plant species tested (Arabidopsis, maize, rapeseed, rice and wheat). We discovered a novel drought tolerance mechanism in plants involving acetate-jasmonate signaling pathway that is regulated epigenetically and conserved in plants. We expect that external application of acetate to plants will be a useful, simple, and cheap way to enhance drought tolerance in a variety of plants.
