EF1A — Cucumis melo

Summary

MELO3C025511.2, designated CmEF1A on melon chromosome 10, encodes a translation elongation factor 1-alpha, a GTP-binding protein with GTPase activity and translation elongation factor activity. It also possesses SUMO transferase activity and SUMO binding, linking it to sumoylation and protein tagging. The gene is associated with translation elongation, regulation of metabolism, and NO storage. It is associated with embryo development ending in seed dormancy and response to abscisic acid. Associations include plant stress response, photosynthetic rate, stomatal opening, abscisic acid sensitivity, flowering time, plant growth and development, and root morphology traits. The encoded protein localises to multiple cellular compartments including the cytosol, nucleolus, chloroplast stroma, mitochondria, vacuole, and plasmodesmata. Studies of related genes in other species link the family to abscisic acid response, stomatal aperture, and viral resistance.
