TBP2 — Brassica oleracea var. botrytis

Summary

BoTBP2, encoded by the gene BOLND125_C06P011320.1 on cauliflower chromosome 6, is a TATA-box binding protein family member (TBP_dom_sf) with TFIIB-class transcription factor binding, GTF2 activity, RNA polymerase binding, and sequence-specific DNA binding. It is associated with DNA-templated transcription initiation, nucleosome assembly, cotyledon and leaf morphogenesis, primary root development, pollen germination, and responses to hypoxia, heat, sucrose, blue light, ABA, and salinity. The gene is linked to yield, seed set, plant height, inflorescence length, chlorophyll content, nitrate content and sensitivity, water stress and oxidative stress responses, and leaf and root development traits. Studies of related genes in other species connect the family to waterlogging tolerance, hypoxia tolerance, cold and drought stress tolerance, and fungal resistance.
