INVINH1 silencing-expression enhanced chilling tolerance of tomato. a 45-d INVINH1 RNAi and wildtype plant were treated at 4 °C for 10 h. The wildtype plant wilted, while INVINH1 RNAi plant remained normal. b Water loss rate of the first and second mature leaves from (a). c The first mature leaf from 60-d INVINH1 RNAi and wildtype plant, which were recovered at 25 °C for 2 h after treated at 4 °C for 48 h. The leaf at this position of INVINH1 RNAi plant returned to normal at this time. d Water loss rate of the leaves from (c). e The third mature leaf from 60-d INVINH1 RNAi and wildtype plant, which were recovered at 25 °C for 120 h after treated at 4 °C for 48 h. The leaf at this position of wildtype plant turned white. By contrast, the leaf at the same position of INVINH1 RNAi remained green at this stage. f The chlorophyll content of the leaves from (e). Each value in (b), (d) and (f)is mean ± SE of at least ten biological replicates. An asterisk indicates a significant difference (t test, *P < 0.05; **P < 0.01)
