ATM4 — Beta vulgaris subsp. vulgaris

Summary

BvATM4 (BVRB_1G002740) on sugar beet chromosome 1 encodes a plant Myb transcription factor with DNA-binding and transcription factor activity, as well as protein dimerization, kinase binding, and calcium ion binding functions. The gene is associated with regulation of raffinose metabolism, glucosinolate biosynthesis, proanthocyanidin and flavonoid anabolism, anthocyanin production, cutin synthesis, trichome morphogenesis and spacing, epidermal cell fate specification, defense responses to insects, drought recovery, and cellular detoxification of cadmium ions. It is linked to numerous traits including seed protein content, lignin biosynthesis, root epidermal cell length, leaf trichome density, shoot elongation under submergence, branch angle, phosphorus response, iron concentration, UV-B light sensitivity, and aphid response. The product localizes to the nucleus, cytosol, root hair, and preprophase band. Studies of related genes in other species connect the family to suberin synthesis, cuticle development, drought response, glucosinolate content, and trichome differentiation.
