EF1A — Lactuca sativa

Summary

LsEF1A, located on chromosome 1 of garden lettuce (Lactuca sativa), encodes a translation elongation factor 1-alpha (EF1A) family protein with GTPase activity, GTP binding, and translation elongation factor activity, and is also annotated with SUMO transferase activity and SUMO binding. The gene is associated with translation elongation, sumoylation, and regulation of metabolism, as well as embryo development ending in seed dormancy and response to abscisic acid. It is linked to plant stress response, photosynthetic rate, stomatal opening, abscisic acid sensitivity, flowering time, plant growth and development, and root morphology traits. The encoded protein localizes to multiple cellular compartments including the cytosol, chloroplast stroma, mitochondria, vacuole, nucleolus, and plasmodesmata. Studies of related genes in other species connect the EF1A family to immune response and embryo viability.
