RLK — Solanum lycopersicum

Summary

SOLYC02G078170.3, designated SlRLK, encodes a transmembrane receptor protein serine/threonine kinase with a legume lectin domain, coreceptor activity, histidine kinase activity, and sugar binding. In tomato, this gene is associated with lycopene and auxin content, fruit size, leaf curling, self-incompatibility, ethylene sensitivity, and defense responses against herbivory and Fusarium crown and root rot. It is linked to pollen aperture formation, cell wall modification, sucrose transport, the MAPK cascade, and methyl jasmonate-mediated stomatal closure. The protein localizes to the plasma membrane, endoplasmic reticulum, nucleus, and cytosol. Related genes in other species are linked to stomatal immunity and resistance to Pseudomonas syringae.
