  1. 1 sequences showing only similarity to organelle genomes. 2 sequences showing only similarity to bacterial sequences or the highest similarity to bacterial sequences; the origin of these putative bacterial contaminations is currently not clear, as bacteria-free cultures of Mesostigma were used. 3similarity to proteins with a well-defined function (BLAST score >100). 4similarity to conserved proteins with no established function (BLAST score >100). 5low similarity to proteins from a few organisms (BLAST score generally between 100 and 200); might reflect conserved protein domains.
