Figure 7.

HPR1 mutants show a reduced Glc level at the end of the night under shorter photoperiods. Plants were grown in normal air with 10/14-h, 12/12-h, and 16/8-h day/night cycles. Leaves of three individual plants at developmental stage 5.1 (Boyes et al., 2001) were harvested in the middle (MoD) and the end (EoD) of the day and the middle (MoN) and the end (EoN) of the night. Mutant-to-wild-type ratios of mean relative metabolite contents ± sd are shown (n = 3), with the mean wild-type values arbitrarily set to 1.
