Abstract

Previously we identified aminooxy compounds as auxin biosynthesis inhibitors. One of the compounds, aminooxyacetic acid (AOA) inhibited indole-3-acetic acid (IAA) biosynthesis in rice and tomato. Here, we found that AOA induced auxin over-accumulation in Arabidopsis. The results suggest that auxin-related metabolic pathways are divergent among these plant species.
