CA1 — Brassica oleracea var. botrytis

Summary

BoCA1, located on chromosome 5 of cauliflower (Brassica oleracea var. botrytis), encodes a beta-carbonic anhydrase with carbonic anhydrase activity, peroxidase activity, salicylic acid binding, mRNA binding, zinc binding, and protein binding functions. It is associated with response to carbon dioxide, cell redox homeostasis, heterotrophy, negative regulation of stomatal complex development, regulation of stomatal movement, defence response to fungi, and response to cold. The protein localises to the chloroplast thylakoid membrane, stromule, chloroplast envelope, apoplast, cytosol, and plasmalemma. BoCA1 is associated with stomatal density and movement, light response and gene expression, cold response, immunity, drought and salt tolerance, anther cell differentiation, mitochondrial complex I assembly, embryo and seed development, and antioxidant response. Studies of the Arabidopsis relative SABP3 link the family to disease resistance.
