ERS — Solanum lycopersicum

Summary

SOLYC06G053710.3 (ERS, also known as ETR4) on tomato chromosome 6 encodes a protein with dual-specificity protein kinase activity, histidine phosphotransfer kinase activity, ethylene receptor activity, and copper binding. The gene is associated with ethylene metabolism and signaling, detection of the ethylene stimulus, and is linked to fruit ripening, fruit shelf life, and fruit firmness. It is also associated with fruit color, lycopene and beta-carotene content, leaf carbon content, photosynthetic ability, respiration rate, and responses to water stress, temperature stress, sulfur, aluminum, and nematodes. Additional associations include root number, shoot fresh weight, anther morphology, and aphid response. Related genes in other species link the family to ethylene signal transduction, senescence, and resistance to necrotrophic pathogens.
