UniProt Comments
Small GTPase playing a general role in disease resistance signaling pathway. Acts downstream of heterotrimeric G protein alpha subunit. Regulates cell death and reactive oxygen species production, probably through NADPH oxidase. Also involved in sphingolipid elicitor (SE)-dependent defense signaling. Activates phytoalexin production and alters defense-related genes. Down-regulates metallothionein 2b, a reactive oxygen scavenger (PubMed:10485927, PubMed:11149940, PubMed:12237405, PubMed:15220467). May control lignin synthesis through regulation of both NADPH oxidase and CCR1 activities during defense responses. Stimulates lignin synthesis in suspension cell culture (PubMed:15951489).
