ATM4 — Asparagus officinalis

Summary

A4U43_C03F6310 (ATM4) on asparagus chromosome 3 encodes a protein with a Myb domain and SANT/Myb domain, and is associated with sequence-specific DNA binding, protein dimerization activity, and calcium ion binding. The gene is associated with regulation of raffinose metabolic process, regulation of glucosinolate biosynthetic process, regulation of proanthocyanidin anabolism, regulation of flavonoid anabolism, pigment accumulation, regulation of trichome morphogenesis, trichome spacing, regulation of defense response to insect, and drought recovery. It is linked to cellular detoxification of cadmium ion, cellular response to sulfur starvation, and plant epidermal cell fate specification. Associations with traits include seed protein content, lignin biosynthesis trait, shoot elongation under submergence, root epidermal cell length, leaf trichome density, phosphorus response, iron concentration, UV-B light sensitivity, and brassinosteroid content. Studies of related genes in other species link the family to cuticle deposition, suberin synthesis, and drought response.
