MOLECULAR PHYLOGENY OF THREE SPECIES OF LAND SNAILS (STYLOMMATOPHORA AND ACHATINIDAE), ARCHACHATINA MARGINATA (SWAINSON, 1821), ACHATINA ACHATINA (LINNAEUS, 1758), AND ACHATINA FULICA (BOWDICH, 1822) IN SOME SOUTHERN STATES AND NORTH CENTRAL STATES IN NIGERIA.

- Abstract
Partial sequences of mitochondrial gene cytochrome oxidase sub unit 1 (CO1) and ribosomal RNA 18S nuclear encoding gene of 43 individuals belonging to two genera in order Stylommatophora and the family Achatinidae (Archachatina and Achatina) were obtained to investigate molecular phylogeny in the family. The CO1 was found to be highly variable while the 18S was found to be highly conserved yielding invariable sequences. Several primers were also tested both for the mitochondrial and nuclear genomes but CO1 produced the best results giving single and clear bands. Four main genetic phylogroups/clades were identified within the Bayesian tree constructed and all the four clades were supported by bootstrap values of 100% and also were supported by bootstrap values above 79% in the NJ. Two unidentified species used in the analysis were found in the basal clade which may mean that they were of ancient origin. This study provides preliminary and novel insights on the molecular phylogeny of the snails' species, though there is still a need to collect samples of other species in this family to provide a more robust phylogenetic relationship of achatinid snails in Nigeria.
