Popis: Map-based cloning and photoperiod response detection suggested that CsFT is the critical gene for cucumber photoperiod domestication. Photoperiod sensitivity is important for sensing seasonal changes and local adaptation. However, day-length sensitivity limits crop geographical adaptation and it should be modified during domestication. Cucumber was domesticated in southern Asia and is currently cultivated worldwide across a wide range of latitudes, but its photoperiod sensitivity and its change during cucumber domestication are unknown. Here, we confirmed wild cucumber (Hardwickii) was a short-day plant, and its flowering depends on short-day (SD) conditions, while the cultivated cucumber (9930) is a day-neutral plant that flowers independently of day length. A photoperiod sensitivity locus (ps-1) was identified by the 9930 × Hardwickii F
