EBP — Capsicum annuum

Summary

CaEBP (T459_08152) on pepper chromosome 3 encodes an AP2/ERF domain-containing protein with DNA-binding, transcription coactivator activity, and binding capabilities for lead ions, fatty-acyl-CoA, microtubules, and chromatin. It is associated with responses to hypoxia, anoxia, ethylene, nitrate starvation, superoxide, and lead ions, as well as chlorophyll metabolism, fatty acid metabolism, lipid transport, nitric oxide anabolism, trichome papilla formation, lateral root morphogenesis, and regulation of root development, nitrogen utilization, protein breakdown, and gene expression. The gene is linked to traits including pungency, yield, seed set, plant size, shoot elongation, nitrate sensitivity, male sterility, anther and stamen morphology, flower and inflorescence development, trichome morphology, root hair length, adventitious rooting, and sensitivities to gibberellic acid, jasmonic acid, cytokinin, and UV-B light. Studies of related genes in other species connect the family to hypoxia tolerance, submergence tolerance, freezing tolerance, heavy metal resistance, and seed oil composition.
