BDL — Asparagus officinalis

Summary

A4U43_C01F7170 (AoBDL) on asparagus chromosome 1 encodes an Aux/IAA family protein with domains including AUX_IAA and PB1-like, and is annotated with auxin receptor activity, auxin binding, DNA-binding transcription factor activity, and ubiquitin-protein transferase activity. The gene is associated with auxin signalling, the TIR1-IAA-AUX/IAA interaction, and ubiquitination and degradation of AUX/IAA proteins. It is linked to numerous developmental processes, including embryonic pattern specification, inflorescence meristem growth, phyllotactic patterning, primary root development, and positive regulation of leaf senescence. Associations with traits include lateral root number, adventitious root number, shoot meristem development, phyllotaxy, phototropism, and responses to nitrate, water stress, and osmotic stress. Studies of related genes in other species link the family to apical-basal patterning, lateral root development, vascular tissue identity, and stress tolerance.
