AUR3 — Zea mays

Summary

ZM00001EB108330 (AUR3, also known as VAS2, ZmTLD2, and several GH3 family designations) on maize chromosome 2 encodes a GH3 protein with IAA amido synthetase, ja-amino synthetase, and adenylyltransferase activities, and is associated with red/far-red light photoreceptor activity. The gene is associated with hormone metabolism, jasmonic acid metabolism, carotenoid metabolism, and responses to mycotoxins and light stimuli. Associations include traits such as grain yield, ear weight, tassel branch number, photoperiod-sensitive flowering time, photosynthetic ability, plant growth hormone response, and root architecture. It is also linked to aerenchyma formation, lignin biosynthesis, and responses to biotic stress including insect damage and viral disease. Studies of related genes in other species link the family to auxin and salicylic acid homeostasis and pathogen response, and to resistance and root growth.
