PICODIV will amass large amount of data –cultures –sequences –environmental data Databases –keep track of data produced –verify the data –avoid errors –make data quickly available to all EU requirement PICODIV databases

ARB aligned - phylogeny (trees) - probe design Sequence data bases: output Raw sequences - BLAST Access database Full sequences All sequences Web periodic update
Import files under EMBL format Mark all new sequences aligned: date + person (e.g. 20-jun-2000 DV) pub: n or PICODIV author: e.g. K Valentin Fast align by finding the closest relative with the PT-server SSU_RNA Quick add marked species to existing tree (use a sub-tree rather than the full tree) If tree incorrect remove from tree and align again to closest relative (either known or from BLAST search) Save only changes (not whole database) Update PT-Server ARB processing
Novel sequences have not been added to the full tree (tree_all_dec98), except for mitochondrial sequences. Two subtrees have been extracted and new sequences added to them: Tree nameMethodSequencesType of sequences added tree_all_dec98 Parsimony13804mito tree_euk_algae Parsimony1695nuclear: only lower eukaryotes tree_cyano_plastid Parsimony341cyanobacteria and plastids ARB trees
