CUM1 — Capsicum annuum

Summary

CaCUM1 (T459_11130) on pepper chromosome 4 encodes a translation initiation factor 4E (eIF4E) family protein with RNA m7G cap binding, translation initiation factor activity, and additional annotated molecular functions including linoleate 13S-lipoxygenase activity and salicylic acid binding. The gene is associated with responses to viruses, fungi, bacteria, herbivores, wounding, jasmonic acid, and abiotic stresses such as UV-B light. It has been linked to potato virus Y resistance, pepper veinal mottle virus resistance, photoperiodic flowering, floral organ development, circadian rhythm, nitrogen use efficiency, plant yield, insect resistance, jasmonate biosynthesis, and root growth traits. The protein localizes to stress granules, P-bodies, and the cytosol. Studies of related genes in other species connect the family to potyvirus resistance, salt tolerance, green leaf volatile production, and biotic stress resistance.
