ETR — Brassica oleracea var. botrytis

Summary

BoETR (BOLND125_C06P043610.1_BOLND125_V1) on cauliflower chromosome 6 encodes an ethylene receptor with histidine kinase, dual-specificity protein kinase, and phosphorelay sensor kinase activities, and binds ethylene, heme, and histones. This gene is associated with detection of ethylene stimulus, ethylene-mediated signaling, jasmonic acid/ethylene-dependent systemic resistance, regulation of stem cell renewal, seedling development, and post-embryonic root development, as well as calcium ion homeostasis, hydrogen peroxide biosynthesis, cytokinin metabolism, and alkane anabolism. It localizes to the endoplasmic reticulum, Golgi, plastid, plasmodesma, and secretory vesicle. BoETR is linked to seed yield, days to flowering, leaf morphology, stem elongation, anther morphology, photosynthetic ability, stomatal resistance, water stress response, aluminum response, aphid response, herbicide sensitivity, and traits including leaf carbon content, iron concentration, anthocyanin content, and lignin biosynthesis. Related genes in other species connect the family to ethylene signal transduction, fruit ripening, flower senescence, and disease resistance.
