RLK — Solanum lycopersicum

Summary

SOLYC02G092940.3, designated SlRLK, encodes a transmembrane receptor serine/threonine kinase with leucine-rich repeat domains, exhibiting histone H2AS1 kinase activity, steroid binding, and signaling receptor activity. In tomato, SlRLK is associated with lycopene content, fruit size, auxin content, leaf curling, and self-incompatibility. The gene is linked to drought tolerance, ABA response, cellular response to drought, sucrose transport, sexual reproduction, upregulation of seed germination, organ growth, regulation of floral meristem size, cell wall modification, auxin anabolism, lycopene anabolism, MAPK cascade, protein kinase A activation, and trans-autophosphorylation. The product localizes to the plasma membrane and extracellular regions. Studies of related genes in other species connect the family to plant height, root morphology, abscisic acid sensitivity, immunity, and low nitrogen stress tolerance.
