| Research Abstract |
Auxins are a group of phytohormones that regulate many aspects of plant growth and development. Phenylacetic acid (PAA) has been known as a naturally-occurring auxin as well as indole-3-acetic acid (IAA), but its physiological function is still unknown. Here we elucidate that PAA is produced from phenylpyruvate by YUCCA flavin-containing monooxygenases, which catalyze a rate-limiting step in IAA biosynthesis. We further show that PAA is recognized by IAA receptors TIR1/AFBs, whereas not by IAA polar transporters, suggesting that IAA and PAA play different physiological roles in plants.
