ERS — Asparagus officinalis

Summary

A4U43_C04F18260 (ERS) on asparagus chromosome 4 encodes a protein with ethylene receptor activity, histidine kinase activity, and dual-specificity protein kinase activity, and contains domains including ETR1_N, GAF, and a histidine kinase domain. The gene is associated with ethylene-mediated signaling, detection of ethylene stimulus, and the jasmonic acid/ethylene-dependent systemic resistance pathway. It is linked to fruit ripening, fruit shelf life, seed yield, drought tolerance, photosynthetic capacity, root development traits, and responses to nematodes, aphids, and aluminum. Studies of related genes in other species connect the family to ethylene signal transduction, disease resistance, and osmotic stress tolerance. The gene is also associated with traits including leaf carbon content, water stress response, and temperature stress response.
