CUM2 — Brassica oleracea var. botrytis

Summary

BoCUM2, located on chromosome 4 of cauliflower (Brassica oleracea var. botrytis), encodes a protein containing MIF4G-like and ARM-type fold domains. The gene product exhibits translation initiation factor activity, mRNA binding, DNA binding, protein binding, and zinc binding, and is associated with translation initiation, regulation of translation, sumoylation, and heat acclimation. BoCUM2 localizes to the cytoplasm, nucleus, cytosol, and extracellular regions. The gene is linked to plant growth and development traits, oxidative stress response, abscisic acid sensitivity, and salt tolerance. It has been connected to viral resistance, particularly against turnip crinkle virus, as well as heat stress response, acquired thermotolerance, basal immunity, and defense responses. Related genes in other species are linked to delayed flowering, slower root elongation, thermo-resilience, and cucumber mosaic virus resistance.
