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.

Bean rust, caused by Uromyces appendiculatus, is a devastating disease of common bean (Phaseolus vulgaris) in the Americas and Africa. The historically important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen that overcome other rust resistance genes. Existing molecular markers tagging Ur-3 for use in marker-assisted selection produce false results. Here, w...

We characterized indigenous common bean rhizobia from five districts of the state of Minas Gerais, Brazil. The isolates were trapped by two common bean varieties, the Mineiro Precoce (Andean origin) and Ouro Negro (Mesoamerican origin). Analysis by BOX-PCR of selected isolates detected a high level of genetic diversity.

Fusarium wilt caused by Fusarium oxysporum Schltdl. f.sp. phaseoli (Fop), is one of the important diseases of the common bean in Iran and many of the bean growing countries. Incidence of the disease has been reported in tropical and semi-tropical regions of the world. This study was carried out to characterize genetic diversity of F. oxysporum isolates from the common bean by vegetative compati...

Common bean (Phaseolus vulgaris L.) cultivars actually released in Brazil have to present a high spectrum of disease resistance, which is nationwide one of the main causes for the low productivity of this crop. This is especially true for small farms with low-technology plantations, but which play an important role; altogether, they account for the greatest fraction of the product for the domes...
