16S and 23S plastid r DNA phylogenies of P rototheca species and their auxanographic phenotypes

Because algae have become more accepted as sources of human nutrition, phylogenetic analysis can help resolve the taxonomy of taxa that have not been well studied. This can help establish algal evolutionary relationships. Here, we compare A uxenochlorella protothecoides and 23 strains of P rototheca...

Summary:Because algae have become more accepted as sources of human nutrition, phylogenetic analysis can help resolve the taxonomy of taxa that have not been well studied. This can help establish algal evolutionary relationships. Here, we compare A uxenochlorella protothecoides and 23 strains of P rototheca based on their complete 16S and partial 23S plastid r DNA sequences along with nutrient utilization (auxanographic) profiles. These data demonstrate that some of the species groupings are not in agreement with the molecular phylogenetic analyses and that auxanographic profiles are poor predictors of phylogenetic relationships.
