The 65 protein-coding genes in 45 representative species were extracted from NCBI for construction of the phylogenetic trees [24]. Nucleotides were translated into amino acids using Geneious [59]. Amino acid sequence homologies were aligned by MUSCLE [60]. Aligned genes were concatenated into functional categories [24,66].
