The complete nucleotide sequences of bean common mosaic necrosis virus strains NL-5, NL-8 and TN-1
Bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV) belong to the genus Potyvirus and are probably the most economically important viruses affecting common bean (Phaseolus vulgaris L.). Of the two viruses, BCMNV has been the most important in common bean production in North America, East Africa and Europe due to significant yield losses incurred from infected fields . BCMV and BCMNV are transmitted in a non-persistent manner by several aphid species. All known strains of each virus can be highly seed-transmitted in bean and are distributed worldwide, in large part as a result of movement of contaminated seed [4, 5]. Drijfhout  originally separated the two viruses and their associated strains into eight different pathogroups based on host reaction to infection under specific temperature regimes. Strains NL-5 and NL-3 from Africa were originally assigned to the BCMV pathogroup VI by Drijfhout , and NL-8 was assigned to pathogroup III according to host...
