ERS — Cucumis sativus

Summary

CSA_2G070880 (ERS/ETR1) on cucumber chromosome 2 encodes a protein with histidine kinase activity, ethylene receptor activity, copper binding, and dual-specificity protein kinase function, containing GAF, histidine kinase, and receiver domains. The gene is associated with sex determination and differentiation, flower formation, fruit ripening, fruit set timing, and female flowering. It is linked to detection of ethylene stimulus, response to carbon starvation, nematode parasitism, aphid resistance, powdery mildew susceptibility, and water stress response. Associations include leaf carbon content, photosynthetic ability, respiration rate, seed yield, heterosis, lignin biosynthesis, adventitious root formation, lateral root development, drought tolerance, aluminum resistance, and temperature stress response. Related genes in other species connect it to ethylene signal transduction, senescence, disease resistance, root-knot nematode resistance, iron acquisition, and osmotic stress tolerance.
