ETR — Camelina sativa

Summary

CsETR (CSA16G023760) on Camelina sativa chromosome 16 encodes an ethylene receptor with histidine kinase activity (EC 2.7.13.3), dual-specificity protein kinase activity, and ethene binding. The protein contains GAF, histidine kinase, and receiver domains. CsETR is associated with detection of ethylene stimulus, regulation of seedling development, and jasmonic acid/ethylene-dependent systemic resistance. It has been linked to seed yield, days to flowering, stem elongation, leaf morphology, anther morphology, photosynthetic ability, stomatal resistance, water stress response, high temperature stress response, aluminum response, aphid response, herbicide sensitivity, anthocyanin content, lignin biosynthesis, and iron concentration. Localization evidence connects CsETR to the endoplasmic reticulum membrane, plastid, plasmodesma, and Golgi complex. Studies of related genes in other species link the ETR family to ethylene sensing, flower senescence, disease resistance, and nutrient deficiency responses.
