PHYTOREF

The PhytoREF database provides an access to plastidial 16S rRNA gene sequences of a large diversity of photosynthetic eukaryotes with curated and normalized taxonomy. PhytoREF has been built using the publicly available sequences and plastidial genomes from GenBank, as well as, new amplicon sequences obtained from numerous cultures of marine phytoplankton. Stringent quality filtering and phylogeny-based taxonomic classification were applied for each single 16S rRNA gene sequence. All the major eukaryotic lineages that perform photosynthesis or keep a relict plastid are represented in PhytoREF, and comprise terrestrial, freshwater and marine taxa (land plants, marine and freshwater macro and microalgae).
