Fig. 2From: Molecular characterization and expression patterns of a non-mammalian toll-like receptor gene (TLR21) in larvae ontogeny of common carp (Cyprinus carpio L.) and upon immune stimulationPhylogenetic analysis of TLR21 amino acid sequences. The evolutionary tree of known TLR21s in fish and birds. These trees are generated using the method of Neighbour-Joining in MEGA 6. The GenBank accession numbers of these sequences are shown in the treesBack to article page
