- Key message
- Here, we clone and characterize DST (drought and salt tolerance)-a previously unknown zinc finger transcription factor that negatively regulates stomatal closure by direct modulation of genes related to H(2)O(2) homeostasis-and identify a novel pathway for the signal transduction of DST-mediated H(2)O(2)-induced stomatal closure
- Loss of DST function increases stomatal closure and reduces stomatal density, consequently resulting in enhanced drought and salt tolerance in rice
- A previously unknown zinc finger protein, DST, regulates drought and salt tolerance in rice via stomatal aperture control
- We identify that DST(reg1), a semidominant allele of the DST gene, perturbs DST-directed regulation of OsCKX2 expression and elevates CK levels in the reproductive SAM, leading to increased meristem activity, enhanced panicle branching, and a consequent increase of grain number
- Here, we report that the zinc finger transcription factor DROUGHT AND SALT TOLERANCE (DST) directly regulates OsCKX2 expression in the reproductive meristem
- Our study reveals that, as a unique regulator of reproductive meristem activity, DST may be explored to facilitate the genetic enhancement of grain production in rice and other small grain cereals
- Importantly, the DST(reg1) allele provides an approach to pyramid the Gn1a-dependent and Gn1a-independent effects on grain production
- Rice zinc finger protein DST enhances grain production through controlling Gn1a/OsCKX2 expression
- DST-directed expression of OsCKX2 regulates CK accumulation in the SAM and, therefore, controls the number of the reproductive organs
- The results suggest that OsSRO1c has dual roles in drought and oxidative stress tolerance of rice by promoting stomatal closure and H(2)O(2) accumulation through a novel pathway involving regulators SNAC1 and DST
- Expression of DST, a reported zinc finger gene negatively regulating H(2)O(2)-induced stomatal closure, and the activity of H(2)O(2)-scavenging related enzymes were significantly suppressed, and H(2)O(2) in guard cells was accumulated in the overexpression lines
