生物活性:
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.

体外研究:
3-Acetonyl-3-hydroxyoxindole (AHO) (500-700 nM) increases in endogenous SA levels and phenylalanine ammonia-lyase (PAL) activity.3-Acetonyl-3-hydroxyoxindole (0-500 nM) increases the expression of pathogenesis-related gene 1 (PR-1) in tobacco.
