ERS — Solanum lycopersicum

Summary

SlERS (SOLYC04G064840.1) on tomato chromosome 4 encodes a dual-specificity protein kinase with histidine kinase activity, ethylene receptor activity, and copper binding, placing it in the HisK_dim/P_sf family. The gene is associated with detection of ethylene stimulus and the jasmonic acid/ethylene-dependent systemic resistance pathway. It is linked to fruit ripening, fruit firmness, fruit color, fruit shelf life, and fruit set timing, as well as leaf carbon content, leaf area, shoot fresh weight, root number, and photosynthetic ability. Additional associations include responses to water stress, temperature stress, nematode damage, aphid response, aluminum response, phosphorus response, and sulfur sensitivity. The gene is also associated with programmed cell death induced by symbiont, regulation of starch metabolism, and calcium ion homeostasis. Related genes in other species are linked to senescence, osmotic stress tolerance, and iron acquisition.
