BI1 — Brassica oleracea var. botrytis

Summary

BoBI1 (BOLND125_C02P060560.1_BOLND125_V1) on cauliflower chromosome 2 encodes a Bax inhibitor 1-related protein, a member of the Bax_inhbtr1_CS family. The product is associated with protease binding, calcium channel activity, oxidoreductase activity, heme binding, and proton-transporting ATPase activity. It is linked to very-long-chain fatty acid and glucosinolate biosynthesis, calcium signaling, regulation of photomorphogenesis and stomatal movement, and downregulation of programmed cell death. Associations include responses to cold, UV, insects, and fungi, as well as root development. The protein localizes to the vacuolar membrane, endoplasmic reticulum, nuclear envelope, chloroplast envelope, and plasmodesmata. BoBI1 is associated with traits such as drought tolerance, water use efficiency, cadmium concentration, flowering time, stem elongation, root hair length, and disease tolerance. Studies of related genes in other species link the family to cell death suppression, stress tolerance, and ion homeostasis.
