Overexpression of GhLAC15 in Arabidopsis improved resistance to Verticillium dahliae. (a, b) Four‐week‐old plants were inoculated by root dipping with 5 × 107 conidia/mL. Transgenic (b) and wild‐type (a) plants showed marked differences in Verticillium wilt resistance. Transgenic plants were more resistant than wild‐type plants. (c–e) Disease resistance was assessed by measurement of the inflorescence height (c) and plant dry weight (d), as well as the percentage of leaf chlorosis (e). The significance of differences was analysed with the t‐test (P ＜ 0.01). Data are presented as average values with standard deviation (n = 39). Col, wild‐type Arabidopsis; OE, transgenic Arabidopsis.
