ELG — Solanum lycopersicum

Summary

SlELG, encoded by tomato gene SOLYC04G039730.3 on chromosome 4, is a transmembrane receptor protein serine/threonine kinase with leucine-rich repeat domains. The gene is associated with diverse molecular functions including peptide binding, GTPase binding, calcium-dependent phospholipid binding, and transcription regulator activity. SlELG is linked to immune response-regulating signaling pathways, protein kinase A activation, and cellular responses to peptides and UV-B. In tomato, the gene family member SERK1 is associated with potato aphid resistance. SlELG is associated with numerous agronomically relevant traits including grain yield, fruit ripening and development, bacterial blight disease resistance, viral disease response, temperature stress response, plant male sterility, and brassinosteroid content. The gene also shows associations with photosynthetic capacity, root growth, stomatal formation, and defense responses. Studies of related genes in other species link the family to immunity, cell death control, disease resistance, and somatic embryogenesis.
