Significant induction of glucosinolates has been reported after application of different plant hormones in cruciferous
plants. In our study, indole glucosinolates, especially the glucobrassicin (10.9 fold) and neoglucobrassicin (39.5 fold),were induced rapidly after MeJA treatment (Fig. 1A). Several previous studies have proved that MeJA/JA treatments could increase glucosinolate content in Brassica vegetables
