PLANT BIOLOGY Correction for “A synthetic C4 shuttle via the β-hydroxyaspartate cycle in C3 plants,” by Marc-Sven Roell, Lennart Schada von Borzyskowski, Philipp Westhoff, Anastasija Plett, Nicole Paczia, Peter Claus, Urte Schlueter, Tobias J. Erb, and Andreas P.M. Weber, which published May 17, 2021; 10.1073/pnas.2022307118 (Proc. Natl. Acad. Sci. U.S.A. 118, e2022307118).
The authors note that Table 1 appeared incorrectly. Specifically, the unit for Rdark appeared as “µmol CO2 m−2 ⋅ s0.1” but should instead appear as “µmol CO2 m−2 ⋅ s−1.”

The CCP, Amax, and the slope were determined from the A/Ci curves (SI Appendix, Fig. S8). Dark respiration (Rdark) was determined from the light response curves, and the O2 dependency of the CCP was determined at low oxygen concentrations (4%). One-way ANOVA with a post hoc Tukey honest significant difference test was used for statistical analysis. The different superscript letters indicate significant differences between genotypes at P < 0.05. n ≥ 3. Shown are mean ± SD.
The authors also note that the author contributions footnote appeared incorrectly. The corrected author contributions footnote appears below. These errors have been corrected in the online version.
