Occurrence of sequence mismatch between the universal V4 pPNA and the plastid 16S V4 locus across 500 land plant species. a We queried NCBI GenBank accessions and found six independent occurrences of mismatch including five plant families (Juglandaceae, Melastomataceae, Vivianaceae, Asteraceae, and Cactaceae), and one genus from the Orobanchaceae (Epifagus). b Plant taxa of the phylogenetic tree in a are colored according to the particular nucleotide mismatch between the universal V4 pPNA and plastid 16S V4 locus. We note that Juglandaceae, Vivianaceae, and Cactaceae are represented with only a single taxon and whether or not the observed mismatch extends to other members of these families is unknown
