CUM1 — Brassica oleracea

Summary

BoCUM1 (BOLC102_C08P018040.1) on cabbage chromosome 8 encodes a protein with translation initiation factor activity and RNA m7G cap binding, placing it in the eIF4E family. The gene is associated with responses to viruses, herbivores, fungi, bacteria, wounding, jasmonic acid, and photoperiodic flowering, as well as lipid oxidation, jasmonic acid anabolism, and green leaf volatile biosynthetic process. It is linked to traits including aphid response, disease tolerance, leaf and stem senescence, root hair length and thickness, stomatal complex closure time, UV-B light sensitivity, and plant yield. The protein localises to the cytosol, plastid, chloroplast thylakoid membrane and envelope, nucleolus, P body, and stress granule. Studies of related genes in other species connect the family to potyvirus resistance, salt tolerance, and green leaf volatile biosynthesis.
