Multiple nuclear pseudogenes of mitochondrial cytochrome b in Ctenomys (Caviomorpha, Rodentia) with either great similarity to or high divergence from the true mitochondrial sequence

Article Abstract:

Thirteen species of Ctenomys, a fossil rodent of South America, and a fragment of its mitochondrial cytochrome b gene have been studied. Five different groups of sequence were found. One corresponds to the functional mitochondrial gene. The study reinforces recent observations suggesting the frequent transfer of ht mtDNA sequences to the nucleus and shows how important it is to take great care in interpreting PCR-generated sequences, especially those produced with universal primers. Mammal and bird data are reviewed relative to PCR-generated nuclear copies of cytochrome b.

The evolution of ultraviolet patterns in European Colias butterflies (Lepidoptera, Pieridae): a phylogeny using mitochondrial DNA

Article Abstract:

A molecular phylogeny using mitochondrial DNA related to evolution of ultraviolet patterns in European Colias butterflies (Lepidoptera, Pieridae) is discussed. Reconstruction of the phylogeny was used to find out about colonizing patterns and spread, and also to show whether the species with or without UV patterns make up two monophyletic groups or are polyphyletic, and it was found that UV presence is polyphyletic in the whole group and in each clade, apparently a trait under intra- and/or interspecific selection.

Statistical Data Included, Ultraviolet radiation, Heredity, Cytochrome oxidase

Mitochondrial DNA and chromosomal studies of wild mice (Mus) from Turkey and Iran

Article Abstract:

Chromosomal and mitochondrial DNA studies have been carried out in wild mice (Mus) from Iran and Turkey in the area of the putative source of the M. m. domesticus subspecies. Complete D-loop sequences of 20 Mus from three places in Turkey and seven in Iran were characterized.
