Key message

Map-based cloning and photoperiod response detection suggested that CsFT is the critical gene for cucumber photoperiod domestication.

Abstract

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 F2 segregating populations, which span a ~ 970 kb region and contain 60 predicted genes. RNA-seq analysis showed that the critical photoperiod pathway gene FLOWERING LOCUS T (CsFT) within the ps-1 locus exhibits differential expression between 9930 and Hardwickii, which was confirmed by qRT-PCR detection. CsFT in Hardwickii was sensitive to day length and could be significantly induced by SD conditions, whereas CsFT was highly expressed in 9930 and was insensitive to day length. Moreover, the role of CsFT in promoting flowering was verified by overexpression of CsFT in Arabidopsis. We also identified the genetic variations existing in the promoter of CsFT among the different geographic cucumbers and suggest they have possible roles in photoperiod domestication. The results of this study suggest that a variation in photoperiod sensitivity of CsFT is associated with day neutrality and early flowering in cultivated cucumber and could contribute to cucumber cultivation in diverse regions throughout the world.
