Submergence Confers Immunity Mediated by the WRKY22 Transcription Factor in Arabidopsis

Salicylic Acid Regulates Arabidopsis Microbial Pattern Receptor Kinase Levels and Signaling

“…FLS2 also accumulated after 4 h of water spray treatment without wounding (Supplemental Figure 1K). Accumulation of FLS2 in response to water treatment is consistent with a previous report that immunity-related (also flg22/FLS2) WRKY22 and FRK1 transcripts are also induced by submergence (Hsu et al, 2013). After pretreatment, the levels of FLS2 and BAK1 in acd6-1 total extracts were also affected, but to a lesser extent (Supplemental Figure 1J).…”

Group VII Ethylene Response Factors in Arabidopsis: Regulation and Physiological Roles

“…Submergence-triggered immunity has been observed in Arabidopsis and ascribed to one of the submergence-inducible WRKY TFs, WRKY22 (Hsu et al, 2013). Interestingly, the observed transcriptional responses caused by constitutive WRKY22 expression are very similar to the transcriptome-level changes triggered by AtRAP2.12 stabilization under fully aerated conditions (Giuntoli et al, 2017).…”

The Innate Immune Signaling System as a Regulator of Disease Resistance and Induced Systemic Resistance Activity AgainstVerticillium dahliae

“…In the case of K165-treated wrky22, the high endophytic amounts of the pathogen reflect the participation of WRKY22 in the K165-mediated ISR. WRKY22 regulates innate immunity genes, defense genes, and PRR-related genes (Hsu et al 2013) and its activation is induced by flg22 and N-acyl-homoserine lactones (AHL) (Schikora et al 2011). AHL are involved in bacterial quorum sensing.…”
