ATC — Cucumis sativus

Summary

CsATC (CSA_6G452100) in cucumber encodes a phosphatidylethanolamine-binding protein (PEBP family) with transcriptional co-regulator and DNA-binding transcription factor activity. It is associated with the regulation of flowering time, photoperiodism, and the transition from vegetative to reproductive phase, as well as responses to short-day conditions, vernalization, and sucrose. The gene is linked to meristem determinacy, flower formation, seed germination, and abiotic stress responses including drought tolerance and salt tolerance. It localizes to the nucleus, cytoplasm, ER, vacuole, vesicle, and plasmalemma. Associations with inflorescence architecture, spikelet floret size, photosynthetic rate, and yield-related traits such as seed yield and fruit weight have been noted. Studies of related genes in other species connect this gene family to shoot determinacy, plant architecture, and growth habit.
