BDL — Asparagus officinalis

Summary

A4U43_C07F18300 (symbol BDL, preferred name AoBDL) on asparagus chromosome 7 encodes an AUX/IAA family protein with auxin receptor activity, auxin binding, DNA-binding transcription factor activity, and ubiquitin-protein transferase activity. It is associated with auxin signalling, including TIR1-IAA-AUX/IAA interactions, ubiquitination and degradation of AUX/IAA, and ARF inactivation. The gene is linked to numerous developmental processes, including embryonic pattern specification, meristem development, inflorescence phyllotactic patterning, primary root development, and positive regulation of leaf senescence. It has been connected to traits such as adventitious root number, lateral root number, shoot meristem development, phyllotaxy, phototropism response, nitrate sensitivity, and water stress response. Related genes in other species link the family to apical-basal patterning, root meristem growth, vascular tissue development, and stress responses including drought and salt tolerance.
