HAC1 — Brassica oleracea var. botrytis

Summary

BoHAC1, located on chromosome 8 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with histone acetylase activity, chromatin DNA binding, transcription coactivator activity, protein dimerization activity, zinc binding, DNA binding, DNA binding transcription factor activity, and protein binding functions. It contains CBP/p300/RT109_HAT, CBP_P300_HAT, and multiple zinc finger domains. The gene is associated with protein acetylation, response to low humidity, guard cell fate commitment and differentiation, photoperiodism and flowering, positive regulation of transcription by RNA polymerase II, and upregulation of cell differentiation. It localizes to the nucleus, transcription regulator complex, histone acetylase complex, and mediator complex. BoHAC1 is linked to arsenic accumulation and tolerance, arsenite efflux, arsenic translocation, bacterial resistance, herbivore defense, leaf senescence, floral development, root development, plant size, starch degradation, oxidative stress tolerance, hypocotyl elongation, shoot regeneration, and sugar response. Related genes in other species are linked to root-to-shoot arsenic translocation, flowering time, fertility, thermotolerance, cell cycle progression, ethylene signaling, and stomatal development.
