Flowering time in skip-1/FRI, skip-1/fve, and skip-1/flk double mutants, and in skip-1 transgenic lines overexpressing FLC. a Rosette leaf number in WT, skip-1, skip-1/FRI, skip-1/fve, and skip-1/flk plants under LD conditions. b Rosette leaf number in WT plants, skip-1, and three skip-1 transgenic lines (D1-12, D4-9, and D16-23) transformed with the 35S:FLC construct under LD conditions. The data are the mean ± s.d. (n = 12–27 in a; n = 18–23 in b). c FLC expression as measured by qRT-PCR in WT plants, skip-1, and skip-1 transgenic lines carrying the 35S:FLC construct. ACT2 was used as an endogenous control. Three technical replicates were performed. The values are the mean ± s.d.
