Study of phylogeny based on truss analysis and molecular characterization in freshwater catfish: Eutropiichthys vacha
Verma J and Serajuddin M
The present study investigates the morphological variations between three different stocks and analysis of nucleotide sequences based on major (45S) and minor (5S) ribosomal DNA in freshwater catfish Eutropiichthys vacha. On the basis of truss analysis univariate analysis of variance showed all significant morphometric measurements ((P<0.05) in three groups of E. vacha out of 78 characters studied. In linear discriminant function analysis (DFA), the overall assignment of individuals into their original groups was 91.7%. The proportion of individuals correctly classified into their original groups was 88%. The principal component analysis (PCA) scatter plot and dendrogram also showed high degree of variation among three different stocks of E. vacha. The molecular characterization, provide the sequence length range and GC % of each region using different primers in the subject species. Findings of the present study would be utilized to understand the Morphological variations and complete set of genome in the IUCN listed species of E. vacha.
