Secondary structure of mitochondrial 12S rRNA among fish and its phylogenetic applications.
The complete 12S ribosomal RNA(rRNA) sequences from 23 gobioid species and nine diverse assortments of other fish species were employed to establish a core secondary structure model for fish 12S rRNA. Of the 43 stems recognized, 41 were supported by at least some compensatory evidence among vertebrates. The rates of nucleotide substitution were lower in stems than in loops. This may produce les...
متن کاملLouse (Insecta: Phthiraptera) mitochondrial 12S rRNA secondary structure is highly variable.
Lice are ectoparasitic insects hosted by birds and mammals. Mitochondrial 12S rRNA sequences obtained from lice show considerable length variation and are very difficult to align. We show that the louse 12S rRNA domain III secondary structure displays considerable variation compared to other insects, in both the shape and number of stems and loops. Phylogenetic trees constructed from tree edit ...
متن کاملMitochondrial Diversity and Phylogenetic Structure of Marghoz Goat Population
The genetic diversity and phylogenetic structure was analyzed in Marghoz goat population by mitochondrial DNA sequences. Phylogenetic analysis was carried out using hyper variable region 1 (968 bp) obtained form 40 animals. Marghoz goat proved to be extremely diverse (average haplotype diversity of 0.999) and the nucleotide diversity values 0.022. A total of 40 Marghoz goats were grouped into s...
متن کاملPhylogenetic relationships among the species of the genus Testudo (Testudines: Testudinidae) inferred from mitochondrial 12S rRNA gene sequences.
To test phylogenetic relationships within the genus Testudo (Testudines: Testudinidae), we have sequenced a fragment of the mitochondrial (mt) 12S rRNA gene of 98 tortoise specimens belonging to the genera Testudo, Indotestudo, and Geochelone. Maximum likelihood and neighbor-joining methods identify two main clades of Mediterranean tortoises, one composed of the species Testudo graeca, Testudo ...
متن کاملUniversal primers to amplify the complete mitochondrial 12S rRNA gene in marine fish species.
A pair of new universal 12S mitochondrial rRNA gene primers was designed through multiple alignment analysis of the mitochondrial tRNA(Phe) and the 5' region of 16S mitochondrial rRNA genes of different kinds of fishes. The primers were successfully used to amplify an expected product fragment of about 1.2 kb from various marine fish species, and the amplified DNA fragment was recognized to con...
