Figure 3

Phylogenetic relationship of the 13895 BAC-end sequences (BESs) with the NCBI Nucleotide database. The best hit to the NCBI Nucleotide database of each BES was determined by BLASTn [39] and the phylogenetic distribution of these hits was visualised with MEGAN [40]. Phylogenetic tree structure was derived from the NCBI taxonomy database. Circles represent taxons and their diameter is proportional to the number of BESs with an assigned hit. Numbers next to circles indicate the number of BESs inclusively mapped to a taxon (includes counts of daughter-taxons).
