Opis:
The origin of the Piast dynasty is a matter of lively discussions and disputes. At least a few controversial hypotheses exist, but their credibility is difficult to assess due to the scarcity of written as well as material sources, especially from the time of Polish state formation. Life sciences, however, can support history and archeology. Application of genetic tests, used earlier mainly in forensic laboratories, enabled identification of the remains of King Richard III, the Romanov dynasty members and Nicolaus Copernicus. Contemporary DNA studies, based on next generation DNA sequencing, outreach the narrow area of known markers such as mitochondrial DNA (mtDNA) and selected regions of Y chromosome. Although ancient DNA (aDNA), extracted from remains, is usually highly degraded and contaminated with genetic material of microorganisms, there are methods which allow for the analysis of such material and retrieval of information about origin, kinship and some phenotypic features of an individual. Genetic studies of the Piast dynasty, a subject of our research project, have to deal with numerous difficulties. In or der to gain access to bone samples, we need to meet a number of formal requirements. Moreover, despite the existence of available abundant documentation on the Piast burials, the actual situation is not always consistent with the written sources. Our first experiences show how difficult it is to localize the remains, identify them and extract DNA of sufficient quality.

Opis:
Mitochondrial cytopathies are heterogeneous group witch may be caused by mutations in the mitochondrial as well as nuclear DNA. The most frequent type of inheritance is the maternal type. Difficulties with establishment type off inheritance are caused either by heterogeneous phenotype among family members or by de novo mutations. The phenotype diversity is defined by heteroplasmy and by limitary effect. Heteroplasmy (coexistence of wild-type and mutated DNA) may occur on cellular or on mitochondrial level. The grade of heteroplasmy may change in particular cells and tissues. We presented a case of 45-year-old man with multifocal brain lesion, cardiomyopathy with atrioventricular heart block with implanted cardiostimulator and epilepsy. Since patient was 20 year old he have had headache and incidents of transient blindness. In spite of implanting cardiostimulator losses of consciousness had returned. The epilepsy was diagnosed and treatment was initiated. In neurological examination we noticed multifocal symptoms. Patient was treated in many departments, where SM was suspected (based on MRI findings). Our diagnose was based on absence of clinical data for SM, multisystemic manifestations and issue of anatomopathological muscle biopsy.
Cytopatie mitochondrialne stanowią heterogenną grupę chorób wynikających z uszkodzenia zarówno mitochondrialnego (mtDNA), jak i jądrowego DNA. Najczęstszym typem dziedziczenia jest typ matczyny. Trudności w ustaleniu typu dziedziczenia mogą wynikać z różnorodności klinicznej ekspresji wśród członków rodziny oraz mutacji de novo. Różnorodność fenotypowa uwarunkowana jest heteroplazmią oraz tzw. efektem progowym. Heteroplazmia (współistnienie prawidłowego i zmutowanego mtDNA) może występować na poziomie komórki lub na poziomie poszczególnych mitochondriów. Stopień heteroplazmii zmienia się w poszczególnych komórkach i tkankach. Autorzy przedstawiają przypadek 45-letniego mężczyzny z wieloogniskowym uszkodzeniem OUN, kardiomiopatią z blokiem A-V, po implantacji kardiostymulatora oraz pada - czką. Od 20. roku życia występowały u pacjenta migrenopodobne bóle głowy z incydentami obuocznego zaniewidzenia oraz utraty przytomności, które pierwotnie przypisywano kardiomiopatii i zaburzeniom w układzie bodźco-przewodzącym serca. Pomimo wszczepienia kardiostymulatora utraty przytomności nadal powtarzały się, rozpoznano padaczkę i rozpoczęto terapię. W międzyczasie na podstawie wyniku badania MRI rozpoznano stwardnienie rozsiane; rozpoczęto leczenie. Biorąc pod uwagę całość obrazu klinicznego, przeprowadzono diagnostykę w kierunku choroby mitochondrialnej. Wynik badania histopatologicznego wycinka mięśniowego potwierdził nasze przypuszczenie.

Opis:
Archaeogenomis is a recently developed interdisciplinary research field that utilizes advanced molecular biology techniques, especially DNA sequencing, to study the history of biological species, including humans. Analyses of ancient genomes provide independent information about human ancestors and their migrations, allowing researchers to uncover history of mankind. Here, we present the fundamental principles of archaeogenomics and its application in the studies of biological history of the populations inhabiting central-east Europe.

Opis:
Considered to be the most natural of all other Polish stands Picea abies in Białowieża Forest has suffered severely of bark beetle damages for decades. In order to find out some historical events in native Norway spruce stands diversity at regional level, we carried out the study on poly− morphism with DNA markers and performed Principal Coordinate Analysis (PCoA) on the basis of genetic distance matrix. Two ranges (i.e. Baltico−Nordic and Hercyno−Carpathian) of Norway spruce cover north−eastern and southern Poland, respectively. The spruceless zone separates the these two ranges in lowland Poland. From genetic point of view, the Baltico−Nordic P. abies populations mainly harbor mitochondrial haplotype ‘c', whereas the spruces from the Hercyno− −Carpathian range – haplotype ‘a'. Until recently, the Białowieża Forest has been considered to belong to the northern range of spruce occurrence in Europe. Seven populations from Biało− wieża Forest were studied (two of them from the Strict Reserve in Białowieski National Park) according to mitochondrial DNA diversity, and compared with genetic diversity found in 24 other populations located in Białystok Regional Directorate of the State Forests (north−eastern Poland). All studied spruce populations were more than 100 years old and were of natural origin. As result, the spruces from the Białowieża Forest harbored three mitochondrial haplotypes of the nad1 gene (‘c', ‘a' and ‘a1'), with the haplotype ‘a' being more frequently present (>51%) than the hap− lotype ‘c'. The spruce stands from Białowieża Forest have the highest gene diversity (h Nei=0.527) comparing to the other stands from the Białystok RDSF. The PCoA proved the particularity of the spruces from Białowieża Forest grouping them into one cluster of genetic similarity. Our data demonstrated that most of Norway spruces populations from Białystok RDSF harbor haplotype ‘c', which confirms their historical relationship with the Baltico−Nordic range of P. abies in Europe, while most spruces from Białowieża Forest have different historic origin, because they share high frequency of the southern haplotype ‘a'. It also turned out that Norway spruce pop− ulations from two different European ranges met in lowland Poland after the last glacial period, as proved by the presence of two mitochondrial haplotypes ‘a' and ‘c'. It can be assumed, that the spruceless zone was created by human activity in the past millennia. The results of all molecular analyses confirmed the unique character of spruces of Białowieża Forest, which is distinguished by the greater richness of the gene pool in comparison to the region of Białystok RDSF as well as good adaptation to local environmental conditions.

Opis:
The plant material was collected on 34 individuals growing in the Dendrological Garden of Poznań University of Life Sciences (52°25'32,95" N 16°53'39,83" E) and Botanical Garden of Adam Mickiewicz University in Poznań (52°25'11,70" N 16°52'55,07" E). The species for this study originated from Europe, Asia Minor, central and eastern Asia and North America and included: Abies alba, Abies cephalonica, Abies cilicica, Abies equi−trojani, Abies sibirica, Abies koreana, Abies pinsapo, Abies ×insignis, Abies bornmulleriana, Abies homolepsis, Abies holophylla, Abies grandis, Abies concolor, Abies concolor var. violacea, Abies concolor var. lowiana, Abies nordmanniana, Abies ×arnoldiana, Abies nephrolepis and Abies balsamea. The aim of this study was to define the species haplotypes (the length of allele) on the basis of nad5−4 mitochondrial DNA marker detected by capillary electrophoresis. This marker has been suggested as an easy−to−use tool to distinguish species of the Abies genus and it could be species−specific. Seven different haplotypes were identified. The first one appears in the species from Europe, Asia and North America. The second one was detected in firs from Europe and Asia Minor. A. cephalonica and A. sibirica were identified by the third haplotype, which occurs also in A. alba from the Balkan region. The fourth haplotype is characteristic for species from Asia and North America. The fifth and sixth haplotypes were identified in A. pinsapo and A. numidica. The seventh haplotype was detected only in A. holophylla. Applied marker is a very useful for verification of fir species especially allopatric species, less for parapatric ones. This marker is more helpful to exclude the species than to precisely identify them.

Opis:
Mitochondrial DNA marker was applied to 10 populations of silver fir from Poland and one from Belarusia. These populations were located within and beyond the natural range of silver fir. The marker exhibited two highly conserved alleles (first – 230 bp and second – 150 bp) based on an insertion−deletion of 80 bp in the fourth intron of the mitochondrial nad5 gene. The geographical distribution of the maternally inherited mitochondrial variation is known to support the existence of at least two refugia with two recolonizing maternal lineages remaining largely separated throughout the range. Our results provide that in all studied populations the first allele was discovered. Therefore we postulate that the silver fir migrate to Poland from the refugium in western Europe (probably from central Italy).

Opis:
Origin of Norway spruce in the territory of Skrwilno Forest District was studied with the use of mitochondrial mt−D02 region inherited through maternal line. The former suppositions of Jedliński, who claimed that the origin of spruce in this territory was natural, have been confirmed. Concurrently, it has been established that in the majority of tree stands subject to our study there occurs spruce of Carpathian origin. The obtained results together with the palinological data indicate that the northern border of spruce range in Poland runs right through the territory of Skrwilno Forest District and not about 100 km to the south from this place as has been claimed so far.

Opis:
The origin of the Norway spruce in the Kartuzy Forest District was verified using the maternally inherited mitochondrial DNA marker mt15−D02 that shows distinct geographical distribution in Europe. We analyzed 462 trees from 26 populations. The majority of trees were of Alpine origin and they were present in all populations at a frequency of 6−90% (mean 59%). About 30% of trees were of the Carpathian origin and the least abundant (11%) were trees of north−eastern origin. The trees carrying north−eastern type of the mitochondial DNA marker were found only in 13 populations, but at a very different frequency (from 5 to 88%). The possibility of natural origin of Norway spruce in the area of Kartuzy Forest District was shortly discussed.

Opis:
The origin of the Norway spruce in the Gołdap Forest District from the north−eastern part of Poland was verified using the maternally inherited mitochondrial marker mt15−D02, which in Poland displays a geo−graphical specifity. We analyzed 730 trees from 29 populations and 21 plus trees. These populations included four reserves, four registered seed stand and 21 managed tree−stands. As a result of the performed analyses it was found that 8 out of 21 plus trees were non−native. Also 11 out of the 29 investigated pop−ulations contained trees of non−native origin. The scale of this phenomenon varies, although it encom−passes the entire region of the forest district.
