ERS — Beta vulgaris subsp. vulgaris

Summary

BvERS (BVRB_3G056770) on sugar beet chromosome 3 encodes a protein with dual-specificity protein kinase, histidine kinase activity, ethylene receptor activity, copper binding, anthranilate phosphoribosyltransferase activity, and ribosome binding. The protein contains ETR1_N, GAF, histidine kinase, and receiver domains characteristic of ethylene receptors. BvERS is associated with ethylene-mediated signaling pathways, detection of ethylene stimulus, and regulation of starch metabolism, stem cell renewal, and post-embryonic root development. It is linked to leaf area, root hair density and length, seed yield, fruit ripening, photosynthetic ability, drought tolerance, aluminum and temperature stress responses, aphid and nematode responses, and lignin biosynthesis. The gene is also associated with programmed cell death induced by symbionts, jasmonic acid/ethylene-dependent systemic resistance, and hydrogen peroxide biosynthesis.
