Induction of defense genes in pepper roots after exposure to 2,3-butanediol. Expression levels of nine defense genes were quantified by qRT-PCR. Expression of pepper defense-related genes, a salicylic acid (SA) biosynthesis gene Capsicum annum phenylalanine ammonia (CaPAL), two ethylene (ET) and SA signaling related genes systemic acquired resistance gene 8.2 (CaSAR8.2) and basic β-1,3-glucanase (CaPR 2), an ET biosynthesis gene 1-aminocyclopropane-1-carboxylic acid (CaACC), and an ET signaling-related basic class II chitinase (CaChi 2) were evaluated 0 and 3 days after R. solanacearum drench application at 7 days following. Bars indicate standard deviation (n = 4).
