Phylogeny of Nannizzia incurvata, N. gypsea, N. fulva and N. otae by restriction enzyme analysis of mitochondrial DNA
- 29 Downloads
Sequence divergence among Nannizzia incurvata, N. gypsea, N. fulva and N. otae was studied genetically using digestion profiles of mitochondrial DNA with restriction enzymes, Hae III, Hha I, Hind III and Xba I. Only N. fulva was subdivided into two types on restriction profiles. Phylogenetic relationships suggest that 1) N. gypsea is more closely related to N. fulva than N. incurvata, 2) the phylogenetic distance between N. otae and the other three species is larger than the distances between the other three species.
