ATC — Cucumis sativus

Summary

CsATC (CSA_3G180440) on cucumber chromosome 3 encodes a phosphatidylethanolamine-binding protein (PEBP family) with DNA-binding transcription factor activity and transcriptional co-regulator function. The gene is associated with flower formation, photoperiodism, vernalization response, meristem determinacy, and regulation of the vegetative-to-reproductive phase transition. It has been linked to seed germination, response to sucrose, and vacuolar protein sorting. The encoded protein localizes to the nucleus, cytoplasm, ER, vacuole, vesicle, and plasmalemma. CsATC is associated with flowering time, drought tolerance, salt tolerance, photosynthetic rate, inflorescence development, and spikelet floret size. Studies of related genes in other species link the family to inflorescence meristem identity, shoot indeterminacy, seed yield, and senescence, and to growth habit and sympodial growth.
