EF1A — Capsicum annuum

Summary

CaEF1A (T459_16486) on pepper chromosome 6 encodes a translation elongation factor 1-alpha, a GTP-binding protein with GTPase activity and translation elongation factor activity. The gene is also annotated for SUMO transferase activity and SUMO binding, linking it to sumoylation. CaEF1A is associated with translation elongation, carotenoid anabolism, fruit development, embryo development, and response to abscisic acid. It localizes to the cytosol, nucleolus, chloroplast stroma, mitochondria, vacuole, and plasmodesmata. The gene has been connected to fruit color, weight, and size, soluble protein and chlorophyll content, photosynthetic rate, stomatal opening, flowering time, root morphology, and abscisic acid sensitivity. Related genes in other species link the family to abscisic acid response, stomatal aperture, viral resistance, and immune response.
