Aliphatic glucosinolates (AGSLs) in Arabidopsis thaliana are synthesized from methionine derivatives with various side-chain length that are formed from methionine via chain elongation cycle involving MAM1 and MAM3. Biosynthesis of AGSLs is highly affected by defense signaling molecules, including jasmonic acid, salicylic acid and ethylene. In response to exogenously-applied these phytohormones, MAM genes exhibited different induction patterns in Wild-type of Arabidopsis. The changing patterns of AGSL contents were distinctive in single knockout mutants of MAM genes compared with those in Wild-type, suggesting that MAM1 and MAM3 play an important role in the diversity of AGSL profiles in response to hormonal changes.
