Phenotypic analysis of plants overexpressing PvTOC1-N and PvLHY-K. A PvTOC1-N expression in wild-type (WT) and PvTOC1-N-ox plants. B Rosette leaf number in WT and PvTOC1-N-ox plants. C Root lengths of WT and PvTOC1-N-ox plants grown on a ½ × MS culture medium. D Root meristem length in WT and PvTOC1-N-ox plants. E Flowering ratios of WT and PvTOC1-N-ox plants. F PvLHY-K expression in WT and PvLHY-K-ox plants. G Phenotypes of WT and PvTOC1-N-ox plants 45 days after sowing. Scale bar = 7 cm. H Root lengths of WT and PvLHY-K-ox plants on ½ × MS culture medium. I Phenotypes of WT and PvLHY-K-ox plants 45 days after sowing. Scale bar = 7 cm. J Root tip phenotypes of WT and PvLHY-K-ox plants. Scale bar = 50 μm. The lowercase letters indicate statistically significant groups at p < 0.05
