ATM4 — Lactuca sativa

Summary

LsATM4, also known as ATM4, is a garden lettuce (Lactuca sativa) gene on chromosome 8 encoding a protein with a Myb domain and SANT/Myb domain, and with DNA binding, sequence-specific DNA binding, transcription cis-regulatory region binding, DNA binding transcription factor activity, protein dimerization activity, and protein binding. It is associated with regulation of raffinose metabolic process, cellular detoxification of cadmium ion, cellular response to sulfur starvation, regulation of glucosinolate biosynthetic process, regulation of proanthocyanidin anabolism, regulation of trichome morphogenesis, regulation of flavonoid anabolism, trichome spacing, plant epidermal cell fate specification, regulation of defense response to insect, drought recovery, and regulation of primary metabolic process. The gene is linked to traits including leaf trichome density, seed protein content, shoot axis branching, root epidermal cell length, phosphorus uptake, iron concentration, and photoperiod-sensitive flowering time. Related genes in other species link the family to cuticle formation, suberin biosynthesis, and drought response.
