RLK — Solanum lycopersicum

Summary

SOLYC09G011070.1, designated SlRLK, encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, possessing histidine kinase activity and sugar binding. In tomato, this gene is associated with Fusarium crown and root rot resistance. It has been linked to lycopene content, fruit size, auxin content, leaf curling, ethylene sensitivity, self-incompatibility, and methyl jasmonate-mediated stomatal closure. The encoded protein localizes to the plasma membrane, endoplasmic reticulum, nucleus, and pollen aperture, and is associated with processes including pollen aperture formation, MAPK cascade, cell wall modification, sucrose transport, and organ growth. Studies of related genes in other species link the family to stomatal immunity and resistance to Pseudomonas syringae.
