The authors regret that the reported non-synonymous mutation L550V in the PfcPhers gene is a synonymous mutation. We would like to correct this information in the manuscript. In the Results section, second paragraph, it should read: “The L550V mutation was not identified in the set of global field isolates considered here. At this position we detected a synonymous mutation.” In the Discussion, second paragraph, this sentence can be omitted “From these observations, we speculate that for new antimalarial compounds acting on the PfcPhers gene, acquired resistance may occur more rapidly …”. L550V should be omitted from Tables 1 and 2 and Suppl. Table 1. The authors would like to apologies for any inconvenience caused.
