ATC — Solanum tuberosum

Summary

PGSC0003DMG400011707, designated StATC (also known as StCET1, StTFL-1, StCEN, and StBFT), is a potato gene on chromosome 1 that encodes a phosphatidylethanolamine-binding protein (PEBP) family member. The product is annotated with phosphatidylethanolamine binding, DNA-binding transcription factor activity, and transcriptional co-regulator functions. StATC is associated with the regulation of flowering time, photoperiodism, and the transition from vegetative to reproductive phase, including responses to short days and vernalization. It is linked to meristem determinacy, inflorescence development, and flower development. Associations extend to drought tolerance, salt tolerance, seed size, seed yield, photosynthetic rate, and heterosis. The protein localizes to the nucleus, cytoplasm, vacuole, endoplasmic reticulum, and plasma membrane. Studies of related genes in other species connect this family to shoot architecture, growth habit, and inflorescence meristem maintenance.
