Use of 1-(2,3-Dihydroxy-3H-indol-3-yl)acetone

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].
