Drought and salt are two of the most serious threats to food production worldwide, and research on stress tolerance in crops is important for future food security. In this study we identified DCA1, a transcriptional co-activator of DST that is conserved in the world’s three major crops. DCA1 participates in stress tolerance by controlling stomatal aperture through modulation of H2O2 homeostasis in guard cells. This finding not only increases our understanding of the molecular mechanism by which plants withstand harsh environmental conditions, but it may also facilitate future molecular breeding and genetic engineering of drought - and salt-tolerant crops.
