EDS1 — Solanum lycopersicum

Summary

SOLYC06G071280.4, the tomato EDS1 gene on chromosome 6, encodes a protein with an EDS1-like domain and an alpha/beta hydrolase fold, annotated with SUMO-specific endopeptidase, carboxylesterase, lipase and ADP-ribosyl cyclase activities. In tomato, EDS1 is associated with bacterial wilt resistance. The gene is linked to the positive regulation of salicylic acid-mediated signaling, desumoylation, thermomorphogenesis, leaf abscission, and responses to singlet oxygen and UV-C. Associations extend to numerous agronomic traits including yield, seed yield, biomass, chlorophyll content, flowering time, stem elongation, root mass density, stomatal resistance, and responses to biotic stresses such as downy mildew, powdery mildew, aphids, and viral diseases, as well as abiotic stresses like freezing, aluminum, and low temperature. Studies of related genes in other species link the family to pathogen defense, salicylic acid signaling, and drought tolerance.
