ERS — Capsicum annuum

Summary

CaERS (T459_20459) on pepper chromosome 7 encodes a protein with dual-specificity protein kinase activity, histidine kinase activity, histidine phosphotransfer kinase activity, phosphorelay sensor kinase activity, C2H4 receptor activity, ethene binding, copper binding, anthranilate phosphoribosyltransferase activity, ribosome binding, translation initiation factor activity, histone binding, and histidine kinase binding, and contains ETR1_N, GAF, and histidine kinase domains. The gene is associated with detection of ethene stimulus and jasmonic acid/ethene-dependent systemic resistance. It is linked to fruit ripening, fruit shelf life, fruit set timing, and fruit longevity, as well as seed yield, leaf area, photosynthetic ability, and drought tolerance. Additional associations include responses to temperature stress, water stress, osmotic sensitivity, aluminum, nematodes, aphids, and powdery mildew susceptibility. The gene is also linked to adventitious root formation, lateral root development, root hair length, cell growth, anther morphology, and pungency. Studies of related genes in other species link the family to ethylene signal transduction, disease resistance, and nutrient deficiency responses.
