ATM4 — Asparagus officinalis

Summary

A4U43_C03F10900 (ATM4) on asparagus chromosome 3 encodes a protein with DNA-binding, protein-dimerization and transcription-factor activity, and belongs to the plant SANT/Myb domain family. The gene is associated with the regulation of raffinose metabolism, glucosinolate and flavonoid biosynthesis, proanthocyanidin accumulation, trichome morphogenesis and spacing, plant epidermis development, pigment accumulation, cellular detoxification of cadmium ions, response to sulfur starvation, defense against insects, and drought recovery. It has been linked to traits including seed protein content, leaf trichome density, branch angle, shoot elongation under submergence, root epidermal cell length, phosphorus response, iron concentration, lignin biosynthesis, and photoperiod-sensitive flowering. The product localises to the nucleus, cytosol, root hair, preprophase band, cell cortex and TGN.
