ATC — Cucumis sativus

Summary

CsATC (CSA_6G152360) in cucumber encodes a phosphatidylethanolamine-binding protein (PEBP family) with DNA-binding transcription factor activity and transcriptional co-regulator function. It is associated with the regulation of flowering time, photoperiodism, and the transition from vegetative to reproductive phase, as well as meristem determinacy and flower formation. The gene is linked to responses to short-day conditions, vernalization, sucrose, and seed germination. Localization evidence places the product in the nucleus, cytoplasm, ER, vacuole, vesicle, and plasmalemma. CsATC is associated with drought tolerance, salt tolerance, photosynthetic rate, and inflorescence development traits. Related genes in other species link the family to shoot architecture, growth habit, and yield-related traits such as seed yield, fruit weight, and harvest index.
