ELG — Solanum lycopersicum

Summary

SlELG (SOLYC03G078520.4) on tomato chromosome 3 encodes a transmembrane receptor protein serine/threonine kinase with leucine-rich repeat domains. The gene is associated with potato aphid resistance in tomato and has been linked to diverse processes including immune response-regulating signaling, homeostasis of meristem cell number, negative regulation of seed maturation and floral organ abscission, cellular responses to UV-B and humidity, and protein palmitoylation. Associations also include grain yield, fruit ripening and development, bacterial blight and viral disease resistance, brassinosteroid and gibberellin content, lignin biosynthesis, temperature stress response, plant male sterility, self-incompatibility, and aluminum response. The gene product localizes to heterotrimeric G-protein complexes, nuclear envelope, ribosomes, and spindles. Studies of related genes in other species link the family to cell death control, immunity, somatic embryogenesis, and resistance to multiple pathogens including Magnaporthe oryzae and Verticillium.
