Genbank accession number
- Key message
- Modulation of OsWRKY4 transcript levels by constitutive overexpression increases resistance to the necrotrophic sheath blight fungus, concomitant with elevated expression of JA- and ET-responsive pathogenesis-related (PR) genes such as PR1a, PR1b, PR5 and PR10/PBZ1
- In conclusion, we propose that OsWRKY4 functions as an important positive regulator that is implicated in the defense responses to rice sheath blight via JA/ET-dependent signal pathway
- OsWRKY4 is localized to the nucleus of plant cells and possesses transcriptional activation ability
- We propose that OsWRKY80 functions upstream of OsWRKY4 as an important positive regulatory circuit that is implicated in rice defense response to sheath blight pathogen R

- OsWRKY4, TUD1~DSG1~ELF1, ERECT LEAF1 suppresses jasmonic acid response in rice by decreasing OsWRKY4 stability., Here, by conducting yeast two-hybrid assay and in vitro ubiquitination experiments, we demonstrate that ELF1 interacts with the OsWRKY4 transcription factor, a positive regulator of defense responses to rice sheath blight
- OsWRKY4, TUD1~DSG1~ELF1, ERECT LEAF1 suppresses jasmonic acid response in rice by decreasing OsWRKY4 stability., ELF1 decreased the stability of OsWRKY4, whereas exogenous jasmonic acid treatment suppressed this effect of ELF1, resulting in OsWRKY4 accumulation in rice plants
- OsWRKY4, TUD1~DSG1~ELF1, ERECT LEAF1 suppresses jasmonic acid response in rice by decreasing OsWRKY4 stability., These results suggest that ELF1 indirectly controls the expression of PR1b and PR5 genes by regulating the OsWRKY4 protein level, and support a hypothesis that brassinosteroid and jasmonic acid cooperate to maintain the balance between growth and defense responses
- OsWRKY4, TUD1~DSG1~ELF1, ERECT LEAF1 suppresses jasmonic acid response in rice by decreasing OsWRKY4 stability., We conclude that ELF1 participates in the antagonistic interaction between these two phytohormones by suppressing the jasmonic acid response through the down-regulation of OsWRKY4 protein level in rice
