ETR3 — Solanum lycopersicum

Summary

SOLYC04G049990.2, also known as ETR3, encodes a protein with C2H4 receptor activity, ethene binding, histidine kinase activity, and phosphorelay sensor kinase activity. This tomato gene on chromosome 4 is associated with fruit development and ripening, flower development, pollen tube growth, and the regulation of starch metabolism and lycopene anabolism. It has been linked to lycopene content, response to ethylene and ozone, ethylene anabolism, syngamy, virus-induced PTGS, NO storage, and the downregulation of ethylene-mediated signaling. The encoded protein localizes to the ER membrane. Related genes in other species link the family to histidine kinase activity (EC 2.7.13.3).
