Correction for Fukushima et al., Impact of clock-associated Arabidopsis pseudo-response regulators in metabolic coordination

PLANT BIOLOGY Correction for “Impact of clock-associated Arabidopsis pseudo-response regulators in metabolic coordination,” by Atsushi Fukushima, Miyako Kusano, Norihito Nakamichi, Makoto Kobayashi, Naomi Hayashi, Hitoshi Sakakibara, Takeshi Mizuno, and Kazuki Saito, which appeared in issue 17, April 28, 2009, of Proc Natl Acad Sci USA (106:7251–7256; first published April 9, 2009; 10.1073/pnas.0900952106).

The authors note that on page 7255, Fig. 4 appeared incorrectly in part. The regulatory arrow between CCA1/LHY and TOC1 pointed in the opposite direction. This error does not affect the conclusions of the article. The corrected figure and its legend appear below.

Fig. 4.

Proposed output functions of PRR9/7/5. The figure suggests that PRR9/7/5, together with CCA1/LHY and TOC1 (PRR1), generates a normal oscillation rhythm. Furthermore, it shows that PRR9/7/5 is involved in DREB1-dependent regulation of stress-responsive gene expression and photoperiodic control of flowering time. The outputs of PRR9/7/5, such as maintaining central metabolism including that of the TCA cycle and antioxidant vitamins, are also shown. In addition, PRR9/7/5 negatively regulates the biosynthetic pathways associated with chlorophyll, carotenoid-ABA, and α-tocopherol biosynthesis in chloroplasts.
