Bean common mosaic disease is one of the most destructive diseases bean, which important legumes worldwide. It caused by two closely related potyviruses: bean virus (BCMV) and necrosis (BCMNV). Both viruses have spread to all bean-growing areas worldwide become a major challenge in production. In this review, we summarized biology diversity BCMV BCMNV, discussed current knowledge on resistance ...

A multiplex reverse transcription polymerase chain reaction (RT-PCR) assay was developed to simultaneously detect bean common mosaic virus (BCMV), bean common mosaic necrotic virus (BCMNV), and bean golden yellow mosaic virus (BGYMV) from common bean leaves dried with silica gel using a single total nucleic acid extraction cetyl trimethyl ammonium bromide (CTAB) method. A mixture of five specif...

We present here the first complete Bean common mosaic necrosis virus (BCMNV) genomic sequence isolated from virus-infected common bean (Phaseolus vulgaris) in East Timor, and compare it with six complete BMCNV genomes from the Netherlands, and one each from the United States, Tanzania, and an unspecified country. It most resembled the Netherlands strain NL-8 genome.

The most effective control of Bean common mosaic virus (BCMV) and necrosis (BCMNV) is achieved by using the seeds resistant cultivars. During conventional breeding, resistance against BCMV BCMNV in bean can be developed pyramiding strain-nonspecific dominant I gene with strain-specific recessive (bc-) genes for long-term control. In this study, a total 58 genotypes involving registered green dr...

The role of bean common mosaic necrosis potyvirus (BCMNV) and lettuce mosaic potyvirus (LMV) proteins was investigated in terms of their capacity to function as viral movement proteins (MPs). Using Escherichia coli-expressed proteins and microinjection techniques, direct evidence was obtained that both the potyviral capsid protein (CP) and helper component- proteinase (HC-Pro) function in this ...

ABSTRACT A previously unrecognized recessive resistance gene (or allele) was identified in three host group (HG) 3 common bean (Phaseolus vulgaris) cvs. Olathe, Victor, and UI 37, based on genetic analysis of plants from five populations screened with the NL-3 K strain of Bean common mosaic necrosis virus (BCMNV). The gene (or allele) was associated with resistance to leaf stunting and deformit...
