ATM4 — Asparagus officinalis

Summary

A4U43_C03F8630, also known as ATM4, is an asparagus (Asparagus officinalis) gene on chromosome 3 that encodes a MYB transcription factor containing a Myb DNA-binding domain and SANT/Myb domain. The encoded protein exhibits sequence-specific DNA binding, transcription factor activity, and protein dimerization activity. ATM4 is associated with the regulation of raffinose metabolism, cellular detoxification of cadmium ions, response to sulfur starvation, glucosinolate biosynthesis, proanthocyanidin and flavonoid anabolism, pigment accumulation, trichome morphogenesis and spacing, plant epidermal cell fate specification, defense response to insects, drought recovery, and cutin anabolism. The gene is linked to traits including shoot elongation under submergence, root epidermal cell length, leaf trichome density, seed protein content, phosphorus response, brassinosteroid content, lignin biosynthesis, photoperiod-sensitive flowering time, and UV-B light sensitivity.
