EBP — Beta vulgaris subsp. vulgaris

Summary

BvEBP (BVRB_006850) on sugar beet chromosome 0166.scaffold00483 encodes an AP2/ERF domain-containing transcription factor with DNA-binding, transcription coactivator activity, and additional molecular functions including lead ion, fatty-acyl-CoA, and microtubule binding. This gene is associated with responses to hypoxia, anoxia, ethylene, nitrate starvation, and superoxide, as well as regulation of root development, seed dormancy, lateral root morphogenesis, nitrogen utilization, and protein breakdown. It has been linked to traits including yield, seed set, shoot elongation, whole plant size, root hair length, pollen fertility, vegetative growth time, and sensitivities to nitrate, gibberellic acid, jasmonic acid, cytokinin, brassinosteroids, and UV-B light. Phenotypic associations include hypoxia and waterlogging tolerance, submergence tolerance, freezing tolerance, heavy metal tolerance, and lipid metabolism. Related genes in other species link the family to carotenoid biosynthesis and hypoxia response.
