Abstract excerpt

MAIN CONCLUSION: We demonstrated that Arabidopsis peroxidase AtPrx71 inhibits stem growth and gravitropism response via IAA catabolism, and speculate that other vascular plants, including poplar, may have the same functional peroxidase. Poplar peroxidase CWPO-C, which exhibits significant substrate versatility, has been suggested to participate in IAA catabolism. We previously demonstrated that AtPrx71, which...
