ARF8 — Brassica oleracea

Summary

BoARF8 (BOLC102_C04P046510.1) encodes an auxin response factor (ARF) family transcription factor containing B3 DNA-binding, AUX/IAA, and PB1-like domains, with promoter-specific chromatin binding and transcription cis-regulatory region binding activities. In cabbage, BoARF8 is associated with petal morphogenesis, filament development, embryonic pattern specification, de-etiolation, callus formation, cell wall modification, regulation of seed dormancy and germination, downregulation of lateral root development and gibberellic acid signaling, hyperosmotic salinity response, geotropism, and vascular tissue pattern formation. The gene is linked to numerous traits including petal length, adventitious root number, relative growth rate, plant male sterility, anther and stamen morphology, phototropism response, gibberellin biosynthesis, cytokinin sensitivity, root hair length, anthocyanin content, and abiotic stress response. Related genes in other species are associated with parthenocarpy, fruit development, adventitious root formation, anther dehiscence, and clubroot resistance.
