Small example of application usage which is basically a manual for fresh users is in following chapter. Next chapter is about implementation, technical documentation. Finally the paper is shortly summed up with few ideas of development included.
Celem pracy jest stworzenie aplikacji wspierającej analizę zmian genetycznych dla polimorfizmów pojedynczych nukleotydów. Pierwsze rozdziały zawierają wprowadzenie w tematykę zmian genetycznych. W kolejnym rozdziale opisane są sposoby przechowywania informacji genetycznych zarówno przechowywanie struktur takich jak geny i nukleotydy, jak również sposób przechowywania informacji o wariantach genetycznych w publicznych bioinformatycznych bazach danych. Został tam również zamieszczony opis systemów oceniania dla wariantów genowych bazujących na analizie statycznej. W dalszej części opisany został schemat działania aplikacji. Opisana została idea kolejnych etapów obróbki danych od pobrania z bazy do przedstawienia ich w formie wykresów. Kolejny rozdział pracy zawiera opis przykładowego zastosowania aplikacji będący jednocześnie instrukcją obsługi. Implementacja oraz dokumentacja techniczna została zawarta w szóstym rozdziale.

Opis:: Rabbit haemorrhagic disease virus (RHDV) belongs to the family Caliciviridae and is the etiological agent of the haemorrhagic disease, also known as rabbit plague. Its genome is a linear single-stranded (ss) RNA of 7437 nucleotides and the capsid is built from a single structural protein VP60. In connection with the discovery of new RHDV strains, there is a constant need to investigate the genetic variation of this virus and perform phylogenetic analyses which may show the evolutionary relationships among the RHDV strains. Studies on the divergence of RHDV have shown that it is genetically quite stable, although recent observations indicate that some new RHDV strains, significantly different from the original RHDV subtype and the new RHDVa subtype, are appearing. These latest findings suggest that a new group of RHDV strains has evolved. The present review summarizes the current knowledge on the genetic variation and the latest achievements in phylogenetic analyses of RHDV strains isolated in various countries.

Opis:: The genus Nicotiana is one of the largest in the Solanaceae family and includes more than 80 species. The most well-known and widespread species of the genus Nicotiana is tobacco (Nicotiana tabacum), within which there are numerous cultivars. Tobacco is one of the most important industrial plants in Poland and worldwide. The great diversity within the genus makes it an excellent source of variation in a narrowing gene pool and can be used in breeding programmes. Studies of Nicotiana species also concern mechanisms of polyploidisation and evolution. There are also model species within the genus. However, in order to make full use of the collected germplasm resources, a detailed knowledge of the collection materials is necessary. While there are various reports in the international literature describing specific issues, the aim of this paper is to indicate the diversity of species in the genus Nicotiana as a whole on the basis of our own research and available studies. This review covers the characterisation of the genus Nicotiana in terms of origin and geographical distribution, as well as cytogenetic and molecular differences between species. An important aspect is the presentation of the morphological diversity of Nicotiana accessions and the variation in the most important tobacco alkaloids. A very important issue is the resistance of Nicotiana species to bacterial, fungal and viral diseases, which allows their use in resistance breeding.

Opis:: Ionizing radiation has extensive applications in agriculture for inducing mutagenic changes in major field crops, potential breeding purposes, varietal development and crop improvement. This study was conducted to test the efficacy of 0.8, 1.6, 2.4 and 3.6 kGy gamma irradiation doses (Cobalt-60) upon growth and yield performance of edible pea (Pisum sativum L.) in pot culture experiment during 2009. Results demonstrated that higher radiation doses (1.6 and 3.2 kGy) significantly influenced the studied attributes of P. sativum. It was observed that 3.2 kGy had detrimental effects on shoot and pod lengths of pea which were reduced by 14.60 and 17.71 % respectively when compared to control. Differential response of the number of seeds pod-1, 1000 grain weight and dry biomass of pea were recorded at the applied doses. Significant reduction in number of seeds (-14.21 %) but increase in 1000 grain weight (+13.93 %) and dry biomass (+11.32 %) of pea were recorded at 1.6 kGy which revealed stimulatory effects on grain weight and dry biomass. Conversely, radiation dose 3.2 kGy was found detrimental to all the studied parameters except number of pods plant-1 and number of seeds pod-1 which were not affected.

Opis:: This research was carried out to investigate the genetic structure of the 20 F1s rapeseed hybrids established from five female moderate maturity lines and four early maturity male testers, to determine parents showing general combining ability (GCA) and detect crosses showing specific combining ability (SCA). Significant variance of parents and crosses for all the traits indicated the existence of significant genetic variation among the parents and their F1 cross combinations. Significant variance of parents vs. crosses revealed significant average heterosis for all the traits except first pod height and seeds per pod. High narrow-sense heritability estimates for number of branches and pods length, indicate the importance of additive genetic effects for these traits. Hybrid performance was generally better than parental performance for all the traits except number of branches and also the genetic variation of lines × testers for all the traits were more than lines and testers. Most of the crosses with high mean value of pods per plant were yielded from the parental lines with high mean value of this trait. The crosses including L41×Foma2, Zafar×R42 and L22B×R38 with significant positive SCA effects of seed yield had also high mean values (3400, 3311.3 and 2904.2 kg ha-1 , respectively) of this trait.

Wydawca:: Instytut Zootechniki
Cytata wydawnicza:: Ząbek, T., Semik, E., Fornal, A., Bugno-Poniewierska, M. (2014). Genetic variation of two horse breeds in CpG islands of OAS1 locus. Annals of Animal Science, 14(4), 841-850.
Opis:: N N311 539340.
Agnieszka Fornal
Allelic and haplotypic variations at 27 SNP sites identified in four CpG islands of OAS1 were described in a group of Anglo-Arabian and Hucul horses. Variation in the type of less frequent alleles was the source of variability among breeds. A number of putative LD blocks were identified which could be used to study changes in the genetic structure between generations of both breeds concerning susceptibility to flaviviral infections. Some of the identified SNPs may have an impact on the transcriptional activity of OAS1 or could lead to amino acid substitution influencing proper function of OAS1 enzyme. In the light of recent studies, the described genetic variability of investigated CpG islands might be important in view of the effectiveness of viral incorporation into the host genome.
