Figure 7. Effect of JA treatment on anthocyanin inArabidopsis leaves under HT.
(a) Phenotypes of detached Arabidopsis leaves treated with MeJA, Ibu, or MeJA+MG132 and then transfer to grown under normal (25 ℃) or high (40 ℃) temperature. (b) qPCR analysis of the transcript levels of AtCHS , AtDFR , and AtANS inArabidopsis leaves treated with MeJA, Ibu, or MeJA+MG132 and then transfer to grown under normal (22 ℃) or high (40 ℃) temperature. Different letters above the bars indicate significant differences between groups (P<0.05; ANOVA with Fisher’s LSD test).(c) Anthocyanin content of detached Arabidopsis leaves treated with MeJA, Ibu, or MeJA+MG132 and then transfer to grown under normal (22 ℃) or high (40 ℃) high temperature. Different letters above the bars indicate significant differences between groups (P<0.05; ANOVA with Fisher’s LSD test).
