Viral attacks on natural populations of herbaceous forage legumes might have adverse effect on seed and herbage production, hence this study was carried out to investigate the type and incidence of viruses occurring on these plants in Nigeria. Protein A-sandwich (PAS) and antigen-coated plate (ACP) enzyme-linked immunosorbent assays (ELISA) were used to detect ten legume viruses from 100 leaf s...

alfalfa crops were surveyed for the incidence of alfalfa mosaic virus (amv), cucumber mosaic virus (cmv), peanut stunt virus (psv), bean leaf roll virus (blrv), bean yellow mosaic virus (bymv) and bean common mosaic virus (bcmv) in the major growing areas in the southeast and central regions of iran. samples were collected between may 2009 and march 2011 and analyzed for viral infection initial...

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 effects of 2 mM silicon (Si) and 10 mM KNO₃ (N)-prime signals for plant resistance to pathogens-were analyzed in healthy and Cowpea chlorotic mottle virus (CCMV) or Cowpea mild mottle virus (CMMV)-infected Bradyrhizobium-nodulated cowpea, yardlong bean and mung bean plants. In healthy plants of the three Vigna taxa, nodulation and growth were promoted in the order of Si + N > N > Si > contr...

Faba bean is a major grain legume widely cultivated in many countries.There are a large number of viruses damaging faba bean crop. In this survey, during 2011-2012 growing seasons, to determine the distribution of Bean yellow mosaic virus (BYMV), Bean common mosaic virus (BCMV), Cucumber mosaic virus (CMV), Tomato spotted wilt virus (TSWV) and Alfalfa mosaic virus (AMV), 630 samples were collec...

Common bean (Phaseolus vulgaris) is an annual grain legume that was domesticated in Mesoamerica (Central America) and the Andes. It is currently grown widely also on other continents including Africa. We surveyed seedborne viruses in new common bean varieties introduced to Nicaragua (Central America) and in landraces and improved varieties grown in Tanzania (eastern Africa). Bean seeds, harvest...

introduction: plant diseases caused by geminiviruses are one of the main constraints of legume production in the world. they are responsible for a constraint on production of various crops. geminiviruses are characterized by their twinned icosahedral particles and their single-stranded dna genome. the family geminiviridae is grouped into four genera: begomovirus, mastrevirus, curtovirus and top...
