Versions Notes

In the original publication [1], an error was identified in Figure 5B. The graph for PM2/Ancestral was inadvertently duplicated and used in place of the PM2/Delta panel. As a result, two PM2/Ancestral graphs were presented, and the PM2/Delta graph was omitted. The corrected Figure 5B appears below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.

Figure 5. Antiviral effects of P. mume extracts against SARS-CoV-2 evaluated by plaque assay. (A) Representative plaque assay images showing SARS-CoV-2 treated with PM1–PM8 at a 200 µg/mL concentration. (B) EC₅₀ values of PM2 and PM3 were determined by plaque assays. Plaques were counted, and relative plaque counts were calculated as percentages of the untreated virus control. Data are presented as the mean ± SD from three independent experiments. EC₅₀ values were determined by a four-parameter logistic model.
