molecular characterisation and infectivity of a "legumovirus" (genus begomovirus: family geminiviridae) infecting the leguminous weed rhynchosia minima in pakistan.the legume yellow mosaic viruses (lymvs) that cause extensive losses to grain legumes across southern asia are an evolutionarily unusual group of begomoviruses (genus begomovirus; family geminiviridae) with bipartite genomes. all previously identified lymvs were isolated from leguminous crop species. here we have identified a virus related to the lymvs in a common weed, the legume rhynchosia minima originating from pakistan. analysis of the sequence of the virus shows it to be a typical bipartit ...200919664665
characterization of rhynchosia yellow mosaic yucatan virus, a new recombinant begomovirus associated with two fabaceous weeds in yucatan, mexico.rhynchosia minima (l.) dc. (fabaceae) plants exhibiting bright golden mosaic symptoms were previously associated with begomovirus infection in yucatan, méxico [1]. to characterize the begomovirus infecting these plants, the complete bipartite genome was cloned and sequenced. sequence comparisons indicated that the virus was distinct from all other begomoviruses known to date, including those previously identified from symptomatic r. minima, and the name rhynchosia yellow mosaic yucatan virus (rh ...201020574644
two novel begomoviruses belonging to different lineages infecting rhynchosia minima.rhynchosia minima is a host for several begomoviruses, both in the old world and the new world. in cuba, a whitefly-transmitted disease causing yellow mosaic symptoms, suggested to be of viral origin, was described more than 30 years ago in r. minima, but no information about the nature of the viruses infecting this weed in this country is available to date. here, we report the detection of isolates of two novel begomovirus species infecting r. minima in cuba, which we proposed be named rhynchos ...201020852903
development of bait formulations for control of intermediate hosts of african schistosome species.exploration of methods of snail control indicated a need for a new method because many failures in control programmes are due to lack of contact between molluscicides and the target snail population. the incorporation of molluscicides inside food pellets that are attractive to and ingestible by the target snails is suggested. different concentrations of alcoholic extracts of ambrosia maritima, cucumis prophetarum and rhynchosia minima-molluscicides of plant origin-were compared with niclosamide ...20139418947
wolbachia infections in world populations of bean beetles (coleoptera: chrysomelidae: bruchinae) infesting cultivated and wild legumes.wolbachia endosymbionts are widespread among insects and other arthropods, often causing cytoplasmic incompatibility and other reproductive phenotypes in their hosts. recently, possibilities of wolbachia-mediated pest control and management have been proposed, and the bean beetles of the subfamily bruchinae are known as serious pests of harvested and stored beans worldwide. here we investigated wolbachia infections in bean beetles from the world, representing seven genera, 20 species and 87 popu ...201121728798
