UniProt Comments
Possesses beta-glucosidase activity toward 4-methyl-umbelliferyl-beta-D-glucoside in vitro. Possesses myrosinase activity toward indol-3-yl-methylglucosinolate (I3M) and 4-methoxy-indol-3-yl-methylglucosinolate (4MO-I3M) in vivo (PubMed:19095900). Component of an inducible preinvasion resistance mechanism that prevents penetration of the nonhost fungal species B.graminis and E.pisi (PubMed:16293760). Involved in indole glucosinolate (IGS) activation during pattern-triggered immunity (PTI). Functions as myrosinase for the breakdown of flg22-triggered IGS. Required for both callose deposition and glucosinolate activation during pathogen-triggered resistance (PubMed:19095898). During fungal attack, required for IGS activation that mediates broad-spectrum antifungal defense (PubMed:19095900).
