Phylogenetic analysis
The reference sequences used for the phylogenetic analysis were obtained from the GenBank database (https://www.ncbi.nlm.nih.gov). The nucleotide sequence identity selected was greater than 96% using BLAST (Basic Local Alignment Search Tool) from the National Center for Biotechnology-NCBI (NCBI Resource Coordinators et al., 2018). Sequences were aligned using the MUSCLE algorithm (Edgar, 2004). The phylogenetic tree was constructed by the maximum-likelihood method with 1,000 bootstrap replicates in MEGA 7.0.26 (Kumar, Stecher, & Tamura, 2016).
