ERS — Beta vulgaris subsp. vulgaris

Summary

BvERS (BVRB_7G180490) encodes a dual-specificity protein kinase with histidine kinase activity, ethylene receptor activity, and copper binding, placing it in the ethylene receptor family. In sugar beet, it is associated with detection of the ethylene stimulus, ethylene-mediated signaling, jasmonic acid/ethylene-dependent systemic resistance, and regulation of seedling development, stem cell renewal, and post-embryonic root development. The gene has been linked to numerous agronomic traits including leaf area, root hair density and length, seed yield, fruit ripening, photosynthetic ability, and responses to water stress, temperature stress, nematodes, aphids, aluminum, and osmotic stress. It is also connected to phenotypes such as drought tolerance, fruit shelf life, adventitious root formation, and susceptibility to powdery mildew. Studies of related genes in other species link the family to ethylene signal transduction, disease resistance, and responses to nutrient deficiency and oxidative stress.
