We performed a phylogenetic analysis, based on the partial small subunit rRNA gene (SSU rRNA) sequences from 13 apicoplasts (including new sequences of Sarcocystis muris and Hyaloklossia lieberkuehni) and 16 other plastids, with cyanobacteria as an outgroup. The apicoplast sequences formed a highly supported monophyletic clade with two distinct clades, representing coccidia and haemosporidia, with coccidia divided into Eimeriidae and Sarcocystidae subclades. The coccidian plastid sequences appear to evolve slowly, while their homologues from haemosporidians are more rapidly evolving. Since the apicoplast SSU rRNA gene sequences, when compared with their nuclear homologues, offer a higher number of informative positions, they can be used for phylogenetic inference within the Apicomplexa.
