TOR — Cucumis sativus

Summary

CsTOR (CSA_7G070760) on cucumber chromosome 7 encodes a serine/threonine-protein kinase TOR, a member of the phosphatidylinositol 3/4-kinase family with domains including TOR_cat, FRB, HEAT_ATR, and FATC. The encoded protein possesses protein serine/threonine kinase activity, ATP binding, and transcription cis-regulatory region binding, and localizes to the TOR complex, endosome, and membrane. CsTOR is associated with regulation of autophagy, sucrose-mediated signaling, positive regulation of auxin-mediated signaling, DNA damage checkpoint, and pexophagy. It has been connected to traits including abscisic acid and jasmonic acid content, photosynthetic rate, stomatal resistance, root thickness, seed growth, leaf position, and quantum yield. Studies of related genes in other species link it to cell growth, embryonic development, carbon and nitrogen metabolism, thermotolerance, and viral resistance.
