AXR5 — Asparagus officinalis

Summary

A4U43_C01F11540, designated AoAXR5 (also known as AUX22D, AoIAA27, and SHY2), encodes a member of the AUX/IAA protein family, characterized by AUX/IAA and PB1-like domains, and is annotated with auxin receptor activity, auxin binding, transcription corepressor activity, and sequence-specific DNA binding. In asparagus, this gene is associated with inflorescence phyllotactic patterning, sepal and petal development, response to carbohydrate and red light, and regulation of anthocyanin metabolism. It is linked to biomass yield, photosynthetic ability, photoperiod-sensitive flowering time, root phototropism, leaf angle, and water stress response. Localization evidence connects the product to the nucleus, cytosol, and SCF ubiquitin ligase complexes. Studies of related genes in other species further associate the family with root architecture, fruit development, and stress tolerance.
