Figure 4

Maximum Likelihood phylogenetic tree based on the concatenated nucleotide sequences of 13 PCGs of the Trionychidae species showing the evolutionary relationship of N. nigricans. Bootstrap support values were superimposed with the nodes of ML tree. Species name and respective accession numbers were marked by different color bars as per clade pattern. Species specific taxonomic ranks (subfamily, family, and suborder) were incorporated with the specific clades. The figure was edited in Adobe Photoshop CS 8.0.
