Transcriptome Analysis Provides Insights into Avenanthramide Biosynthesis in Oats under Methyl Jasmonate and Abscisic Acid Cotreatment

-hydroxycinnamoyl transferase (HHT) enzymes, along with 98 transcription factors from MYB, bHLH, HSF, WRKY, bZIP, and ERF families. These results suggest that MJ and ABA cotreatment modulates the expression of key biosynthetic and regulatory genes involved in avenanthramide production in oat seedlings, offering valuable insights for enhancing the nutraceutical value of oats.
