the taxonomic and phylogenetic status of several taxa previously recognized as subspecies inastragalus sect. anthylloidei is re-assessed based on dna sequences and morphologicalfeatures. we focused on astragalus ebenoides (subsp. ebenoides and subsp. naghadehensis),astragalus murinus (subsp. murins and subsp. bornmuelleri), astragalus remotiflorus (subsp.remotiflorus and subsp. melanogramma), a...
Three pandemics have been attributed to plague in the last 1,500 years. Yersinia pestis caused the third, and its DNA was found in human remains from the second. The Antiqua biovar of Y. pestis may have caused the first pandemic; the other two biovars, Medievalis and Orientalis, may have caused the second and third pandemics, respectively. To test this hypothesis, we designed an original genoty...
Methods for identifying species by using short orthologous DNA sequences, known as "DNA barcodes," have been proposed and initiated to facilitate biodiversity studies, identify juveniles, associate sexes, and enhance forensic analyses. The cytochrome c oxidase 1 sequence, which has been found to be widely applicable in animal barcoding, is not appropriate for most species of plants because of a...
BACKGROUND In Africa, relapsing fevers are neglected arthropod-borne infections caused by closely related Borrelia species. They cause mild to deadly undifferentiated fever particularly severe in pregnant women. Lack of a tool to genotype these Borrelia organisms limits knowledge regarding their reservoirs and their epidemiology. METHODOLOGY/PRINCIPAL FINDINGS Genome sequence analysis of Borr...
