Wound-induced jasmonate signaling prevents leaf hyponasty in response to elevated temperature. (A) Representative photographs of undamaged control (Con) WT and jai1-1 plants 5 d after transfer to CT or ET treatment chambers. Other sets of plants were transferred to treatment chambers and simultaneously damaged by caterpillar feeding (M. sexta) or daily mechanical wounding (wound). (B) Quantitation of leaf hyponasty in plants treated as described in A. Following the treatment, the petiole angle of leaf 2 (second oldest) was measured from digital images. Data points represent the mean ± SE of four biological replicates. The table below B shows P values from two-way ANOVA tests of the effect of leaf damage (D), temperature (T), and the interaction of D × T for each of the two genotypes tested (WT and jai1-1).
