Since its publication, the authors of Rúa et al. (2013) have brought to our attention an error in Fig. 3(b) of their article. The key in panel (b) incorrectly described the closed columns as representing +P, and the open columns as −P, when it should indicate: closed columns, −P; open columns, +P. This error was introduced during the formatting of the figures for final publication: the content, results and conclusions of the research described were based on the correct figure and no other aspect of the article was affected by this error. The correct figure is shown below.

Figure 3. Across plant species and phosphorus treatment, mycorrhizal colonization (+AMF vs -AMF) increased relative viral titer as measured by optical density (OD) value for plants under elevated CO2 but had no effect under ambient CO2 (a). Across mycorrhizal status, phosphorus addition (+P vs −P) decreased relative viral titer as measured by ELISA optical density (OD) value for Avena fatua but not for Bromus hordeaceus (b). Data shown are means ± SEM; letters indicate significant pairwise differences between means (Tukey's HSD; P < 0.05).
