The genus Stigeoclonium is taxonomically very problematic. The relationships between species of this genus are very little known. There are only a few studies that deal with only morphological revision of the genus Stigeoclonium. Hovewer, up to now no phylogenetic analysis of this genus exists. This study summarizes the knowledge about the genus Stigeoclonim in the Czech Republic and shows the first phylogenetic analysis of this genus.

This thesis is focused on the assessment of the phylogenetic position of the Myxozoa within the Metazoa, study of the evolutionary relationships within myxosporeans and investigation into the cryptic species assemblages of several myxosporeans based on the ribosomal and protein-coding data. The major part of this work was to confirm the evolutionary trends within myxosporeans based on a single gene by other molecular markers in order to find out if the reconstructed relationships correspond to the real organismal phylogeny. This has been a crucial step for future actions in solving the discrepancies between the myxosporean phylogeny and taxonomy.

This paper describes sequence alignment algorithms of nucleotide sequences. There are described pairwise alignment algorithms using database search or dynamic programming. Then in the paper is description of dynamic programming for multiple sequences and algorithm that builds phylogenetic trees. At the end of the first part of the paper is the description of technology FPGA. In the second part that is more practical is described implemntation of the choosen one algorithm. This part includes also examples of some multiple alignments.
