Erratum: Abscisic acid regulation of guard-cell K⁺ and anion channels in Gβ- And RGS-deficient Arabidopsis lines (Proc. Natl. Acad. Sci. U.S.A. 2008 105 (8476–8481) DOI: 10.1073/pnas.0800980105)

PLANT BIOLOGY Correction for "Abscisic acid regulation of guard-cell K⁺ and anion channels in Gβ- and RGS-deficient Arabidopsis lines," by Liu-Min Fan, Wei Zhang, Jin-Gui Chen, J. Philip Taylor, Alan M. Jones, and Sarah M. Assmann, which was first published June 9, 2008; 10.1073/pnas.0800980105 (Proc. Natl. Acad. Sci. U.S.A. 105, 8476-8481). The authors wish to note the following: "We regret that, due to inadvertent copy and paste duplication within a spreadsheet, incorrect current traces were provided in the original Fig. 1A for Col+ABA traces: The Col+ABA traces of Fig. 1A were inadvertent duplicates of the OX6+ABA traces in Fig. 2A. Correct current traces for this genotype and treatment are provided in the new Fig. 1 below, in which panel A has been revised to correct this error. Panel B in revised Fig. 1 remains unchanged, because the current traces in revised panel A were already correctly included in the original calculations for published panel B. As the data and statistical analysis in panel B remain unchanged, the Fig. 1A corrections do not affect the results nor alter the original conclusion, namely that abscisic acid (ABA) sensitivity of guard cell Kin current regulation is abrogated in these heterotrimeric G protein mutant lines. "We also regret that, due to inadvertent copy and paste duplication, incorrect current traces were provided in the original Fig. 4A for gpa1-4 control and Col+ABA traces. The gpa1-4 control traces were duplicates of the OX6 control traces in Fig. 4B, and the Col+ABA traces were duplicates of the OX6+ABA traces in Fig. 4B. Correct current traces for these genotypes and treatments are provided in the new Fig. 4 below, in which panel A has been revised to correct this error. Panel C in revised Fig. 4 remains unchanged, because the two sets of current traces in revised panel A were already correctly included in the original calculations for published panel C. As the data and statistical analysis in panel C remain unchanged, the Fig. 4A corrections do not affect the results nor alter the original conclusion, namely that outward K⁺ currents in all genotypes exhibit wild-type behavior. We also have corrected Fig. 4E, which contained accidentally duplicated data in the 35 mV current trace for agb1-1 under strong pH buffering in control conditions. Panel G in revised Fig. 4 remains unchanged, because the current traces in revised panel E were already correctly included in the original calculations for published panel G. As the data and statistical analysis in panel G remain unchanged, the Fig. 4E correction does not affect the results nor alter the original conclusion, namely that ABA regulates anion currents in a pH- and G protein-dependent manner. "Raw data for all current traces are provided in spreadsheets that accompany this correction as Supporting Information." The corrected Fig. 1, corrected Fig. 4, and their corresponding legends appear below. Raw data files have been added to the Supporting Information. Dataset S1 contains data for Fig. 1A, Dataset S2 contains data for Fig. 2A, Dataset S3 contains data for Fig. 4 A and B, and Dataset S4 contains data for Fig. 4 E and F. [Figure Presented].
