ETR3 — Solanum lycopersicum

Summary

SOLYC09G065310.1, also known as ETR3, encodes a HisK_dim/P_sf domain-containing protein with C2H4 receptor activity, ethene binding, phosphorelay sensor kinase activity, metal binding, and ATP binding. It is localized to the ER membrane. This tomato gene on chromosome 9 is associated with fruit development and ripening, flower development, pollen tube growth, signal transduction, and the downregulation of ethylene-mediated signaling. It has been connected to lycopene content and lycopene anabolism, as well as ethylene anabolism, response to ethylene and ozone, metabolic burst, syngamy, virus-induced PTGS, and NO storage. Studies of related genes in other species link the family to histidine kinase activity (EC 2.7.13.3).
