EF1A — Cucumis melo

Summary

MELO3C020441.2, designated CmEF1A on melon chromosome 6, encodes a translation elongation factor 1-alpha (EF1A) family protein with GTPase activity, GTP binding, mRNA binding, and translation elongation factor activity. It is also annotated with SUMO transferase activity and SUMO binding, linking it to sumoylation. The gene is associated with translation elongation, regulation of metabolism, nitric oxide storage, embryo development ending in seed dormancy, and response to abscisic acid. It is associated with plant stress response, photosynthetic rate, stomatal opening, abscisic acid sensitivity, flowering time, plant growth and development, and root morphology traits. The protein localises to multiple cellular compartments including the cytosol, chloroplast stroma, mitochondria, vacuole, nucleolus, Golgi complex, and plasmodesmata. Related genes in other species link the family to abscisic acid response, stomatal aperture, and viral resistance.
