EDS1 — Phaseolus vulgaris

Summary

PHAVU_009G183100, designated PvEDS1, 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 French bean (Phaseolus vulgaris, chromosome 9), PvEDS1 is associated with the positive regulation of salicylic acid-mediated signaling, activation of camalexin anabolism, desumoylation, and defense responses to oomycetes, Gram-negative bacteria, insects and viruses. It is linked to traits including disease tolerance, yield, biomass, seed yield, water use efficiency, flowering time, leaf senescence, and responses to biotic and abiotic stresses such as aluminum, low temperature and oxidative stress. The gene product localises to the perinuclear region of cytoplasm, plasmodesma, plastid and endomembrane system. Studies of related genes in other species connect the family to pathogen resistance, salicylic acid accumulation and drought response.
