ERS — Solanum lycopersicum

Summary

SlERS (SOLYC07G056580.3) on tomato chromosome 7 encodes a dual-specificity protein kinase with histidine phosphotransfer kinase activity, ethylene receptor activity, and copper binding, placing it in the ethylene receptor family. The gene is associated with ethylene metabolism and detection, fruit ripening, fruit shelf life, fruit firmness, fruit color, and lycopene content. It is linked to leaf carbon content, photosynthetic ability, respiration rate, shoot fresh weight, root number, drought tolerance, water stress response, temperature stress response, aluminum response, nematode damage response, aphid response, and susceptibility to powdery mildew. Additional associations include seed shattering, days to heading, lignin biosynthesis, anther morphology, and programmed cell death induced by symbiont. The gene product localizes to the ER lumen, plastid stroma, and proteasome. Related genes in other species are linked to ethylene signal transduction, senescence, salinity tolerance, and iron acquisition.
