ELG — Solanum lycopersicum

Summary

SlELG (SOLYC04G005910.3) on tomato chromosome 4 encodes a transmembrane receptor protein serine/threonine kinase with leucine-rich repeat domains, associated with diverse molecular functions including peptide binding, GTPase inhibitor activity, and guanylyl cyclase activity. The gene is linked to immune response-regulating signaling pathways, protein kinase A activation, and cellular responses to peptides and UV-B. In tomato, SlELG has been connected to potato aphid resistance. Broader associations include grain yield, fruit ripening and development traits, bacterial blight and viral disease resistance, brassinosteroid content, hydrogen peroxide levels, temperature stress response, plant male sterility, and floral organ length. The gene is also linked to photosynthetic capacity, root meristem differentiation, nitrate absorption, stomatal formation, and defense responses against fungal pathogens.
