Figure 5From: Genome-wide identification of WRKY45-regulated genes that mediate benzothiadiazole-induced defense responses in riceProposed model for a transcriptional cascade in rice SA pathway. The SA pathway branches into WRKY45- and OsNPR1-dependent pathways. Transcription factors WRKY62, OsNAC4, and HSF1 mediate the SA signal downstream of WRKY45 to regulate defense genes. The gene encoding OsNAC4 is regulated directly by WRKY45, while the factors regulating genes encoding WRKY62 and HSF1 are unclear.Back to article page
