ATM4 — Asparagus officinalis

Summary

A4U43_C07F39310 (ATM4) on asparagus chromosome 7 encodes a protein with Myb_TF_plants, Myb_dom, SANT/Myb, and Homeobox-like_sf domains, and has sequence-specific DNA binding, transcription cis-regulatory region binding, and protein dimerization activity. It is associated with the regulation of flavonoid and proanthocyanidin anabolism, pigment accumulation, glucosinolate biosynthetic process, raffinose metabolic process, cellular detoxification of cadmium ion, response to sulfur starvation, drought recovery, defense response to insects, trichome morphogenesis and spacing, and plant epidermal cell fate specification. The gene product localises to the nucleus, cytosol, root hair, and preprophase band. Associations with traits include shoot elongation under submergence, root epidermal cell length, leaf trichome density, seed protein content, adventitious root number, lignin biosynthesis, photoperiod-sensitive flowering time, and UV-B light sensitivity. Related genes in other species are linked to cuticle deposition, suberin biosynthesis, and drought response.
