Expressioni

Inductioni

By 2,6-dichloroisonicotinic acid (INA) and salicylic acid (possibly an endogenous signal for acquired resistance). Strongly induced by infection with the bacterial pathogen P.syringae pv. tomato DC3000 (PubMed:1392589). Induced by infection with avirulent and virulent strains of P.syringae pv. maculicola (PubMed:1824335). Induced by infection with the turnip vein clearing virus (TVCV) and cucumber mosaic virus (CMV) (PubMed:23656331).3 Publications
