CTR1 — Cucumis sativus

Summary

CSA_3G749850, designated CTR1 (also known as CTR1-like, SIS1, CsSIS1, or CsCTR1) on cucumber chromosome 3, encodes a dual-specificity protein kinase with ethylene receptor activity, ethene binding, and MEKK activity, belonging to the EDR1/CTR1/ARMC3-like protein kinase family. The gene is associated with detection of ethene stimulus, jasmonic acid/ethene-dependent systemic resistance, regulation of seedling development, regulation of post-embryonic root development, and regulation of stem cell renewal. It is linked to traits including fruit ripening, seed yield, root hair length, lateral root length, stem elongation, leaf morphology, anther morphology, temperature stress response, salinity response, aluminum response, aphid response, and herbicide sensitivity. Localization evidence connects the product to the plasmalemma, ER membrane, endosome, cytosol, and nucleolus. Studies of related genes in other species link it to ethylene signal transduction, fruit ripening, disease resistance, and abiotic stress tolerance.
