Introduction of 33417-17-3 :

3-Acetonyl-3-hydroxyoxindole (AHO) is a potent systemic acquired resistance (SAR) inducer in plants. 3-Acetonyl-3-hydroxyoxindole induces resistance in tobacco plants against infection with tobacco mosaic virus (TMV) and the fungal pathogen Erysiphe cichoracearum. 3-Acetonyl-3-hydroxyoxindole increases the level of pathogenesis-related gene 1 (PR-1) expression, salicylic acid (SA) accumulation and phenylalanine ammonia-lyase activity[1]. In Vitro: 3-Acetonyl-3-hydroxyoxindole (AHO) (500-700 nM) increases in endogenous SA levels and phenylalanine ammonia-lyase (PAL) activity[1].
3-Acetonyl-3-hydroxyoxindole (0-500 nM) increases the expression of pathogenesis-related gene 1 (PR-1) in tobacco[1].
