Evidence for the presence of Beet necrotic yellow vein virus types A and B in Poland
Journal of Plant Diseases and Protection 116 (3), 106-108
Abstract: Beet necrotic yellow vein virus (BNYVV), which causes a viral disease of sugar beet known as 'rhizomania', is widely spread throughout the sugar beet growing areas of Poland. The analysis of the molecular variability of two separate regions, namely the part of coat protein (CP) and triple gene block (TGB) genes of the BNYVV genome, revealed very low level of nucleotide sequence diversity among the isolates (98-100% sequence identity). Sequence alignments of BNYVV isolates from Poland and other isolates available to data showed also high level of nucleotide sequence identity among these isolates. Based on multiplex RT-PCR and phylogenetic analysis we distinguished types A and B of BNYVV. The sequence identity matrix between type A and B revealed 92-93% similarity. Mainly, BNYVV type A is widespread in Poland whereas type B has rarely been found. These results suggest that Polish isolates probably originated from Southern Europe rather then from Germany or France where BNYVV type B is a dominating one.
