ERS — Asparagus officinalis

Summary

A4U43_C02F21530 (ERS) on asparagus chromosome 2 encodes a protein with domains characteristic of an ethylene receptor, including ETR1_N, GAF, histidine kinase, and HATPase_C domains, and is annotated with ethylene receptor activity, ethene binding, histidine phosphotransfer kinase activity, and dual-specificity protein kinase activity. The gene is associated with detection of ethylene stimulus, ethylene-mediated signaling pathways, regulation of seedling development, and programmed cell death induced by symbiont. It has been linked to traits including fruit ripening, leaf carbon content, photosynthetic ability, seed yield, water stress response, temperature stress response, aluminum response, aphid response, and nematode damage response. Studies of related genes in other species connect the family to ethylene signal transduction, fruit ripening, senescence, disease resistance, drought tolerance, and root development.
