Arabidopsis displays circadian rhythms in stomatal aperture,
stomatal conductance, and CO2 assimilation, each of which
peaks around the middle of the day. The rhythmic opening and closing of
stomata confers a rhythm in sensitivity and resistance, respectively, to the toxic gas sulfur dioxide. Using this physiological assay as a
basis for a mutant screen, we isolated mutants with defects in
circadian timing. Here, we characterize one mutant, out of phase
1 (oop1), with the circadian phenotype of
altered phase. That is, the timing of the peak (acrophase) of multiple
circadian rhythms (leaf movement, CO2 assimilation, and
LIGHT-HARVESTING CHLOROPHYLL a/b-BINDING PROTEIN
transcription) is early with respect to wild type, although all
circadian rhythms retain normal period length. This is the first such
mutant to be characterized in Arabidopsis. oop1 also
displays a strong photoperception defect in red light characteristic of
phytochrome B (phyB) mutants. The
oop1 mutation is a nonsense mutation of
PHYB that results in a truncated protein of 904 amino
acids. The defect in circadian phasing is seen in seedlings entrained
by a light-dark cycle but not in seedlings entrained by a temperature
cycle. Thus, PHYB contributes light information critical for proper
determination of circadian phase.
