ERS — Solanum lycopersicum

Summary

SlERS (SOLYC09G082910.2) on tomato chromosome 9 encodes a protein with dual-specificity protein kinase, histidine phosphotransfer kinase activity, histidine kinase activity, phosphorelay sensor kinase activity, ethylene receptor activity, copper binding, anthranilate phosphoribosyltransferase activity, ethene binding, histidine kinase binding, ribosome binding, translation initiation factor activity, histone binding, and chromatin binding, belonging to the HisK_dimerisation domain family. The gene is associated with detection of ethylene stimulus, jasmonic acid/ethylene-dependent systemic resistance, regulation of seedling development, regulation of stem cell renewal, regulation of starch metabolism, and programmed cell death induced by symbiont. It is linked to fruit ripening, fruit firmness, fruit colour, fruit set timing, fruit shelf life, and fruit longevity. Additional associations include leaf carbon content, photosynthetic ability, respiration rate, water stress response trait, temperature stress response trait, root number, shoot fresh weight, aphid response trait, nematode damage response trait, aluminum response trait, sulfur sensitivity, and lignin biosynthesis trait. Studies of related genes in other species connect the gene family to ethylene signal transduction, senescence, nematode resistance, salinity tolerance, and iron acquisition.
