REFA1; REFA2; REFA3; REFA4 — Solanum lycopersicum

Summary

SOLYC06G009970.3, also known as REFA1-4, encodes a protein containing translation elongation factor domains and is annotated with translation elongation factor activity, GTPase activity, GTP binding, and mRNA binding, localizing to the cytoplasm. In tomato, this gene is associated with upregulation of glycolysis, glucose homeostasis, sepal morphogenesis, and responses to temperature and ethylene metabolism. It has been linked to numerous agronomically important traits including fruit weight, fruit color, carotenoid and carotene content, carbohydrate and sucrose content, leaf chlorophyll content, photosynthetic ability, quantum yield, seedling vigor, relative yield, leaf water potential, hydrogen peroxide content, root number, lateral root number, flower abortion, stamen length, petal size, stigma color, self-incompatibility, and parasitic weed. Studies of related genes in other species link the family to translation elongation.
