Clock defects underlie the reduced photoperiodic sensitivity of lhy flowering. a Flowering times of lhy mutants under SDs of differential total duration. Plants were grown until flowering under SDs of 24-h or 20-h total duration. Those grown under SDs of 20-h total duration were photographed (left panel). Rosette leaf numbers of 20 plants were averaged and statistically treated (t-test, *P < 0.01) (right panel). Bars indicate SE. b Expression profiles of FT and clock output genes in lhy-7 mutant grown under SDs of 24-h or 20-h total duration. Transcript levels were examined by qRT-PCR. L/D, light/dark. c Flowering phenotype of lhy-7 co-101 double mutant under LDs. The lhy-7 mutant was crossed with the co-101 mutant, resulting in lhy-7 co-101 double mutant. Plants were grown until flowering in soil under LDs (left panel). Flowering times were measured as described in (a) (right panel). d Expression of FT gene in lhy-7 co-101 double mutant grown under either LDs or SDs. Transcript levels were examined by qRT-PCR. Biological triplicates were averaged. Bars indicate SE
