Phylogenetic relationships and karyotype evolution in the sigmodontine rodent Akodon (2n = 10 and 2n = 16) from Brazil

Genetics and Molecular Biology, 2006
Comparison of G-bands from 2n = 10 and 2n = 16 karyotypes of Akodon revealed tandem fusions, pericentric inversions and Robertsonian rearrangement in autosomes and addition/deletion of constitutive heterochromatin in sex chromosomes.

PHYLOGENY OF THE PEROGNATHUS LONGIMEMBRIS SPECIES GROUP BASED ON MITOCHONDRIAL CYTOCHROME-b: HOW MANY SPECIES? [PDF]

Journal of Mammalogy, 2005
The Perognathus longimembris species group currently consists of 3 species and approximately 23 subspecies. Members of this species group have been of considerable interest to biologists in both physiological and ecological studies, and several members are threatened with extinction.

Phylogeny of the East Asian botiine loaches (Cypriniformes, Botiidae) inferred from mitochondrial cytochrome b gene sequences [PDF]

, 2005
The Botiinae have traditionally represented a subfamily of the Cobitidae. At present, the classification and phylogenetic relationships of the Botiinae are controversial.

New mitochondrial genomes of parasites belonging to the Leucocytozoon toddi and Haemoproteus nisi groups (Haemosporida, Apicomplexa)

Parasites & Vectors
Background Avian haemosporidians are single-celled eukaryotic parasites of vertebrates that require dipteran vectors for transmission. The genera Plasmodium, Haemoproteus and Leucocytozoon currently comprise over 5000 parasite lineages based on a 478-bp ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
