Strigolactones suppress drought acclimation in rice by promoting DWARF53 (D53)-dependent reduction of OsWRKY31 and downstream ZFP36-mediated H2O2 scavenging, linked to drought resistance outcomes.
- Why it matters: Drought limits rice yield, and although strigolactones affect stress tolerance, the molecular mechanism and how to tune the pathway for practical drought acclimation in rice remain unclear.
- What they did: The study used short-term dehydration assays, genetic perturbations of strigolactone biosynthesis/signaling, GR24 4DO supplementation, and biochemical interaction tests showing D53 binds OsWRKY31 (N-terminal) to regulate OsWRKY31 and ZFP36 transcription.
- The result: Disrupting strigolactone biosynthesis or signaling increased drought resistance, while activating signaling or adding GR24 4DO impaired it; genome editing and the elite D17/HTD1 allele improved drought resistance and grain yield in field-grown Nekken 2.
