Insect bioassays of SaPIN2b-overexpressing transgenic plants. (A) Each tobacco plant was infected with 10 early second-instar H. armigera larvae for seven days. WT, wild-type plants; VO, vector-only transgenic plants; T1 and T5, SaPIN2b-overexpressing plants. (B) Weight of H. armigera fed on different tobacco lines. * indicates that p < 0.05. (The data were analyzed using the t-test).
