ERS — Solanum lycopersicum

Summary

SlERS (SOLYC09G089610.3) on tomato chromosome 9 encodes a protein with dual-specificity protein kinase activity, histidine phosphotransfer kinase activity, phosphorelay sensor kinase activity, ethylene receptor activity, ethene binding, copper binding, and GAF and histidine kinase domains. The gene is associated with ethylene biosynthesis and signaling pathways, as well as hormone signaling, transport, and metabolism. SlERS has been linked to fruit ripening, fruit set timing, fruit shelf life, and fruit longevity, along with carotene and lycopene content. It is connected to leaf carbon content, leaf area, shoot fresh weight, root number, tiller number, inflorescence number, and carpel number. The gene is also associated with responses to water stress, temperature stress, nematode damage, sulfur sensitivity, phosphorus response, and nutrient responses, as well as lignin biosynthesis, nitrate transport, and amino acid content. Studies of related genes in other species link SlERS to ethylene signal transduction, senescence, and responses to various abiotic and biotic stresses.
