ELG — Solanum lycopersicum

Summary

SlELG (SOLYC05G056370.4) on tomato chromosome 5 encodes a protein with leucine-rich repeat and serine/threonine kinase domains. The gene is associated with diverse molecular functions including transmembrane receptor protein serine/threonine kinase binding, calcium-dependent phospholipid binding, NAD(P)H oxidase H2O2-forming activity, guanylyl cyclase activity, GTPase inhibitor activity, channel regulator activity, peptide binding, and transcription regulator activity. SlELG is linked to potato aphid resistance, immune response-regulating signaling pathways, protein kinase A activation, homeostasis of meristem cell number, negative regulation of seed maturation, and floral organ abscission. The gene is associated with numerous traits including grain yield, fruit ripening and development, bacterial blight disease resistance, viral disease response, temperature stress response, plant male sterility, brassinosteroid content, hydrogen peroxide content, and lignin biosynthesis. Studies of related genes in other species link the family to cell death control, bacterial disease resistance, immunity, and somatic embryogenesis.
