The main aims of diploma thesis were: 1) The sequence analysis of the Czech isolate of Potato virus M (PVM) VIRUBRA 4/009 and phylogenetic analysis of PVM coat proteins sequences 2) The bacterial expression of recombinant triple gene block protein 1 (TGB1) of PVM derived from the Czech isolate VIRUBRA 4/007 3) The construction of expression cassette of Potato leafroll virus (PLRV) coat protein and its transformation into A. tumefaciens for transgenic PLRV resistant plant formation In theoretical part of the thesis the taxonomic classification, morphology, genomic structure and virus transmission are discussed. Furthermore, the main rules concerning the bacterial expression of recombinant proteins and construction of transgenic plants using A. tumefaciens are described. Methodical part is devoted to description of generally used molecular biological and immunochemical methods. The following results were obtained in the thesis: The complete nucleotide sequences of open reading frames coding for three movement proteins (Triple gene block -TGB), coat protein and NA-binding protein of PVM isolate VIRUBRA 4/009; phylogenetic analysis was performed; the TGB1 protein was expressed in bacterial cells and will be used for polyclonal antibodies raising. Finally, the expression cassette containing the PLRV...
