The Santos Lab is happy to offer downloadable datasets and sequence alignments of molecules commonly utilized in Symbiodinium diversity and phylogenetic studies. These alignments are for use as a scaffold to which novel sequences may be added and preliminary phylogenies constructed. Given the rate that new sequences are generated, these alignments are not representative of all sequences available from sources such as NCBI, and are not intended to encompass all Symbiodinium diversity (either within the genus or any particular clade). The alignments are made available in NEXUS format (for use in programs such as PAUP*) and can be converted to other formats using the program seqret in EMBOSS Explorer. If a sequence in the alignment does not have a NCBI accession number (most don't), you can use SYM-BLAST to identify it. To download a file, right-click the link and save it to your computer. For additional sequence alignments of molecules commonly used in Symbiodinium phylogenetics, you may also want to check the NCBI PopSet and TreeBase databases.
