Fig. 7.

Transcription patterns of ET-biosynthetic genes (ACS2 and ACO1) and ET-regulated genes (ETR4 and ERF1) in the leaflets of PSN and Nr after AAL toxin application or co-treatment with AAL toxin and JA. Error bars indicate standard deviation. Letters indicate significant differences in gene expression of Nr treated with AAL toxin alone among different time points (P <0.05, Duncan's multiple range test); asterisks indicate significant differences in gene expression of AAL toxin treatment alone between PSN and Nr as well as in gene expression of Nr between treatment with AAL toxin alone and co-treatment with AAL toxin and JA at each time point (*P <0.05; **P <0.01; Student's t-test).
