ERF48 — Brassica oleracea var. botrytis

Summary

BoERF48 (ERF48/DREB2C) on cauliflower chromosome 4 encodes a protein with an AP2/ERF domain and DNA-binding transcription factor activity, and is annotated with NAD ADP-ribosyltransferase activity. It is associated with ethylene and jasmonate signalling, responses to oxidative stress, ozone, superoxide, heat acclimation, osmotic stress, and glucose-mediated signalling. The gene is linked to upregulation of chlorophyll breakdown, positive regulation of leaf senescence, photoperiodism, flowering, lateral root morphogenesis, glucosinolate metabolism, and pyridoxal and nitric oxide anabolism. It localises to the nucleus and cytoplasm. Associations with agronomic traits include yield, plant height, leaf size, flowering time, chlorophyll content, transpiration rate, stomatal resistance, root development, subterranean shoot axis tuber size, nitrate sensitivity, disease tolerance, and responses to water stress, UV-B, jasmonic acid, abscisic acid, and osmotic stress. Studies of related genes in other species link the family to heat and freezing tolerance, drought and salt tolerance, ABA biosynthesis, and stomatal closure.
