ATM4 — Beta vulgaris subsp. vulgaris

Summary

BvATM4 (also known as BvMYB82, BvMYB41, BvMYB102, RAO7, BvMYB4, BvMYB3, MYB32, MYB76, MYB114, BvMYB39, MYB74, MYB39) on sugar beet chromosome 5 encodes a Myb-domain transcription factor with sequence-specific DNA binding, transcription factor activity, and protein dimerization activity. It is associated with the regulation of raffinose metabolism, cellular detoxification of cadmium ions, response to sulfur starvation, glucosinolate biosynthesis, proanthocyanidin and flavonoid anabolism, trichome morphogenesis and spacing, cutin anabolism, anthocyanin anabolism, defense response to insects, drought recovery, and epidermal cell fate specification. The gene is linked to traits including shoot elongation under submergence, root epidermal cell length, branch angle, leaf trichome density, seed protein content, adventitious root number, brassinosteroid content, lignin biosynthesis, iron concentration, phosphorus uptake, photoperiod-sensitive flowering time, aphid response, UV-B light sensitivity, and osmotic response sensitivity. It localizes to the nucleus, cytosol, root hair, preprophase band, and cell cortex.
