CUM1 — Pisum sativum

Summary

PsCUM1 (PSAT1G192480) on chromosome 1LG6 encodes a protein with translation initiation factor activity and RNA m7G cap binding, placing it in the eIF4E family. It also shows linoleate 13S-lipoxygenase activity and salicylic acid binding. The gene is associated with translation initiation and regulation, response to viruses, herbivores, fungi, bacteria, wounding, and jasmonic acid, as well as lipid oxidation, green leaf volatile biosynthesis, and photoperiodic flowering. It localizes to the cytosol, plastid, stress granules, and P-bodies. Traits linked to PsCUM1 include seed weight, root hair length, stem and leaf senescence, disease tolerance, aphid and insect response, UV-B sensitivity, and stomatal closure. Related genes in other species are associated with potyvirus and potexvirus resistance, salt tolerance, and green leaf volatile production.
