Figure 3. . A) Phylogenetic analysis of a 523-bp region of the partial spike gene of 12 human coronavirus (HCoV)-NL63 isolates from France. To construct the trees, the 2 prototype strains NL63-Amsterdam1 and NL-AY518894 were included. HCoV-229E is used as an outgroup. A) Nucleotide sequence alignments created with ClustalX 1.83; bootstrap values ≥70 are indicated. B) Predicted amino acid sequences; bootstrap values ≥50 are indicated.
