- Key message
- OsWRKY42 represses OsMT1d and induces reactive oxygen species and leaf senescence in rice.
- Our results thus suggest that OsWRKY42 represses OsMT1d-mediated ROS scavenging and thereby promotes leaf senescence in rice
- OsWRKY42 represses OsMT1d and induces reactive oxygen species and leaf senescence in rice
- oryzae by suppressing JA signaling-related genes, and WRKY45-2 transcriptionally activates WRKY13, whose encoding protein in turn transcriptionally suppresses WRKY42 to regulate rice resistance to M
- Expression of the rice transcription factor OsWRKY42 is induced upon treatment of rice leaves with CWDEs, wounding and salt
- OsWRKY42 expressing Arabidopsis lines exhibited enhanced tolerance to methyl jasmonate mediated growth inhibition
- The results presented here suggest that OsWRKY42 regulates plant responses to either cell wall damage or salinity stress by acting as a negative regulator of jasmonic acid mediated responses
- Upon treatment with NaCl, Arabidopsis transgenic plants expressing OsWRKY42 exhibited high levels of anthocyanin and displayed enhanced tolerance to salt stress
- Ectopic expression of OsWRKY42 results in reduced expression of cell wall damage and salt stress induced jasmonic acid biosynthesis and response genes
- Overexpression of OsWRKY42 leads to enhanced callose deposition in rice and Arabidopsis but this does not enhance tolerance to bacterial infection
- Treatment with either one of the two different cell wall degrading enzymes (CWDEs), LipaseA and CellulaseA, induces immune responses and enhances the expression of OsWRKY42 in rice
- However, the role of OsWRKY42 in CWDE induced immune responses is not known

- OsNADK1, OsWRKY42~WRKY42, The NAD kinase OsNADK1 affects the intracellular redox balance and enhances the tolerance of rice to drought., , OsWRKY21 and OsWRKY42, showed correlated co-expression patterns with OsNADK1 in osnadk1 and the plants overexpressing or underexpressing OsNADK1, implying roles for these transcription factors in OsNADK1-mediated processes
- OsMBTB32, OsWRKY42~WRKY42, OsMBTB32, a MATH-BTB domain-containing protein that interacts with OsCUL1s to regulate salt tolerance in rice., Moreover, OsWRKY42, a homolog of ZmWRKY114 which negatively regulates salt stress in rice, directly binds to the W-box of OsCUL1-1 and OsCUL1-3 promoters to promote the interaction of OsCUL1-1 and OsCUL1-3 with OsMBTB32 protein in rice
