The effect of short or long day lengths on expression levels of BM1, BM10, and HvVRT2. A, Relative expression levels of BM1, BM10, HvVRT2, and HvVRN1, assayed by qRT-PCR, in RNA from plants (cv Icheon Naked, minus roots) that were maintained in short days (8 h dark/16 h light) or shifted to long days (16 h light/ 8 h dark) for 7 d. Expression is shown relative to the initial time point (14-d-old plants in short days). B, Expression levels of HvFT, normalized to ACTIN, in the same RNA samples. Error bars show se. Asterisks indicate P values of Student's t tests: *, P < 0.05; **, P < 0.01; ***, P < 0.001.
