ELG — Cucumis sativus

Summary

CsELG (CSA_4G106870) on cucumber chromosome 4 encodes a transmembrane receptor protein serine/threonine kinase with multiple domains including LRR and kinase catalytic domains. The gene product is associated with a wide range of molecular functions such as peptide binding, GTPase binding, calcium-dependent phospholipid binding, guanylyl cyclase activity, and transcription regulator activity. CsELG is linked to biological processes including shoot apical meristem development, immune response-regulating signaling pathways, homeostasis of meristem cell number, negative regulation of seed maturation and floral organ abscission, and responses to UV-B and humidity. The gene has been connected to agronomically important traits including grain yield, fruit length and ripening, bacterial blight disease resistance, plant male sterility, brassinosteroid content, and hydrogen peroxide content. Studies of related genes in other species link the family to defense responses, cell death control, and resistance to various pathogens including Verticillium and Magnaporthe oryzae.
