ETR2 — Brassica oleracea

Summary

BoETR2 (BOLC102_C01P044970.1) on cabbage chromosome 1 encodes an ETR family protein with histidine kinase activity, copper binding, and dual-specificity protein kinase activity. It is associated with detection of ethylene stimulus and the jasmonic acid/ethylene-dependent systemic resistance pathway. The gene is linked to traits including fruit ripening, seed yield, leaf area, stomatal resistance, lateral root length, floral organ development, anther morphology, and responses to temperature stress, osmotic stress, aluminum, aphids, nematodes, and herbicides. It is also associated with phenotypes such as disease resistance to bacterial and oomycete pathogens, camalexin accumulation, flowering time, chloroplast development, and circadian rhythm. Related genes in other species are linked to ethylene sensing, apical hook formation, and root-knot nematode resistance.
