Application of fall armyworm (FAW) regurgitant on sorghum wounded plants enhanced the expression levels of flavonoid pathway genes. RT-qPCR analysis of flavonoid pathway genes (A) FNSII, flavone synthase II; (B) FNR, flavanone 4-reductase; (C) CHS, chalcone synthase; and (D) DFR3, Dihydroflavonol-4-reductase. (E) Total flavonoids estimated using spectrophotometer in leaves of sorghum SC1345 plants after four applications of FAW regurgitant every 24 hours. Undamaged and wounded plants were used as controls (n = 3-4). Error bars represent ± SE. Different alphabets indicate significant difference relative to each other (P < 0.05). W + W, treatments in which water was applied to wounds; W + R, treatments in which FAW regurgitant was applied to wounds.
