Sequences of the first 300 nucleotides of coat protein (CP) genes of 7 isolates of NTN strain of potato virus Y (PVY, PVY(NTN)) were determined and compared with analogous published sequences of various isolates and strains of PVY. The sequence identity among the sequenced isolates ranged from 96 to 100%. The differences were found at different positions.(More)
Coat protein (CP) coding regions of six Potato mop-top virus (PMTV) isolates from the Czech Republic and Denmark (54-10, 54-11, 54-15, 54-19, Korneta and Pacov) were sequenced. Comparison of the obtained nucleotide sequences as well as alignment of the deduced amino acid sequences were performed. The obtained results showed that the isolates from different(More)
A simple and reliable procedure for reverse transcription-polymerase chain reaction (RT-PCR) detection and strain differentiation of Potato virus Y (PVY) was developed. Three primers were designed within the coat protein (CP) and nuclear inclusion protein b (NIb) region, exploiting a single base polymorphism identified as being present in all the(More)
The gene encoding the coat protein (CP) of a potato virus Y (PVY) was cloned into expression vector pMPM-A4Omega. PVY CP was expressed in Escherichia coli and the purified recombinant protein was used for raising rabbit polyclonal antibodies. The sera and antibodies were tested for the detection of PVY in the laboratory host Nicotiana tabacum cv. Petit(More)
The Potato virus X (PVX)-based vector was used for the construction of N- and C-terminally modified PVX coat protein (XCP) chimeras. N-terminal XCP modifications do not influence the viral life cycle, whereas the simple XCP C-terminal fusion impedes the viral replication. We designed several C-terminally modified XCP chimeras and tested their viabilities in(More)
The use of light emitting diodes (LEDs) brings several key advantages over existing illumination technologies for indoor plant cultivation. Among these are that LEDs have predicted lifetimes from 50–100.000 hours without significant drops in efficiency and energy consumption is much lower compared to traditional fluorescent tubes. Recent advances allow LEDs(More)
Eight isolates of potato virus Y NTN strain (PVY-NTN) of different origin were studied by means of monoclonal antibodies (MAbs) in non-competitive and competitive enzyme-linked immunosorbent assay (ELISA), and by immunoblot analysis of the viral coat protein (CP). As the MAbs reacted with the denatured viral CP, their epitopes must be continuous. The ELISA(More)
Six monoclonal antibodies (MoAbs) against potato virus A (PVA) were prepared and used in enzyme-linked immunosorbent assay (ELISA), immunoblot analysis and electron microscopic study of the virus. Four MoAbs, 151, 290, 328 and 634, reacted with purified virus preparation in dot blot test and showed strong reaction also with virus coat protein (CP) denatured(More)
