Figure 1.

Neighbor-joining tree based on 49 L-Lactate dehydrogenase amino acid sequences from 31 taxa. Numbers at nodes indicate the Neighbour-joining and Maximum Parsimony percentage bootstrap support with 2,000 and 100 replicates, respectively. Nodes supported only by the Neighbor-Joining analysis show a single bootstrap value. The scale bar indicates levels of amino acid sequence divergence. The tree was rooted using the plant LDH sequences.
