Mitochondrial genomes are frequently used to infer phylogenetic relationships. Some taxa are, however, poorly represented. To facilitate better understanding of the potential of mitochondrial genome data in freshwater mussels, we present here, for the first time, the mitochondrial sequences of 4 complete F-type mitochondrial genomes from the European(More)
The alien Chinese mussel Anodonta woodiana was first reported in Poland in the system of heated lakes near Konin in 1993. Genetic studies with use of three molecular techniques (isoenzyme electrophoresis, PCR-RFLP and sequence analysis of a COI gene fragment) were carried out on the Polish first populations of A. woodiana. The studies have revealed low(More)
Doubly uniparental inheritance (DUI) of mitochondrial DNA, different from maternal inheritance, is known to occur in five bivalve families (Mytilidae, Veneridae, Unionidae, Margaritiferidae, Hyriidae). DUI involves two types of mitochondrial DNA: F type, inherited from the mother and M type, inherited from the father. Females have only F type mtDNA, males(More)
Central nervous system hemangioblastomas (cHAB) are rare tumours which most commonly arise in the cerebellum. Most tumours are sporadic, but as many as one third of cHABs occur in the course of the hereditary disorder - von Hippel-Lindau disease (VHL). In order to diagnose new VHL families in Poland we performed sequencing of the entire VHL gene in archival(More)
Anodonta anatina is a freshwater mussel of the family Unionidae. These mussels have a unique mitochondria inheritance system named doubly uniparental inheritance (DUI). Under DUI males have two, potentially very divergent mitochondrial genomes: F-type inherited from mother and M-type inherited from father. F-type is present in soma whereas M-type is present(More)
Unlike the vast majority of organisms in which mitochondrial DNA is transmitted maternally (standard mitochondrial inheritance, SMI), some marine or freshwater bivalves exhibit a different pattern of mtDNA transmission, named doubly uniparental inheritance (DUI). In this case there are two types of mtDNA, i.e. the female-transmitted (F-type) and the(More)
Freshwater mussels are among animals having two different, gender-specific mitochondrial genomes. We sequenced complete female mitochondrial genomes from five individuals of Anodonta anatina, a bivalve species common in palearctic ecozone. The length of the genome was variable: 15,637-15,653 bp. This variation was almost entirely confined to the non-coding(More)
Unio tumidus is a native European freshwater mussel from the family Unionidae. These mussels have a unique system of mitochondrial DNA inheritance called doubly uniparental inheritance (DUI). Under DUI, two types of mitochondrial DNA are present: haplotype F (female genome)—inherited from mother and haplotype M (male genome)—inherited from fathers to male(More)
The slugs Arion lusitanicus and Arion rufus inhabit ecologically degraded areas and are serious vegetation pests. In recent years, new localities of these species have been found in various parts of Poland. Here we study the morphology of 90 specimens from 9 populations of slugs. The morphology of the genital system allowed for the identification of 60 A.(More)
Light scattering studies on the giant squid axon were done using the technique of optical mixing spectroscopy. This experimental approach is based on the use of laser light to detect the fluctuations of membrane macromolecules which are associated with conductance fluctuations. The light scattering spectra were similar to the Lorentzian-like behavior of(More)
