The neighbour-joining tree of Cardinium sequences (450 bp). The tree has sequences amplified from F. cinerea in this study and some sequences derived from GenBank. The tree is based on distances estimated by using the Kimura's 2 parameter method with gaps and missing data excluded from pair-wise comparisons. JS: population 1, KoBeach: population 2, KoGrPit: population 5, and KY: population 10. (1000 bootstrap replicates).
