ABF2 — Brassica oleracea

Summary

BoABF2 (BOLC102_C06P002220.1_BOLC102_V1) on cabbage chromosome 6 encodes a bZIP transcription factor of the BZIP46-like family, with calcium-dependent protein kinase activity, protein phosphatase activity, and sequence-specific DNA binding. It is associated with the upregulation of chlorophyll breakdown, glucose-mediated signalling, far-red signalling, wax and unsaturated fatty acid anabolism, regulation of stomatal opening, nitrogen utilization, and positive regulation of autophagy. The gene has been linked to numerous agronomic traits including biomass yield, photosynthetic ability, seed set percent, vegetative vigor, water stress response, photoperiod-sensitive flowering time, plant male sterility, stem senescence, and responses to aluminum, nitrate, magnesium, and UV-B light. Related genes in other species are associated with drought adaptation, freezing tolerance, and enhanced dehydration and salt stress tolerance.
