JA and ethylene pathways play a minor role in A. alternata-induced transcription of NaEASs and NaEAHs, and capsidiol biosynthesis. (A, B) Mean (±SE) relative A. alternata-induced NaEASs (A) and NaEAHs (B) transcripts as measured by real-time PCR in five biological replicates of young leaves (0 leaves) in WT, irAOC (JA deficient), irACO (ethylene deficient), and Ov-etr1 (ethylene insensitive) plants at 1 and 3 dpi. (C) Mean (±SE) capsidiol levels determined by HPLC in five replicate 0 leaves of WT, irAOC, irACO, and Ov-etr1 plants at 3 dpi. ND, not detectable.
