Application of phylogenetic networks in evolutionary studies.
The evolutionary history of a set of taxa is usually represented by a phylogenetic tree, and this model has greatly facilitated the discussion and testing of hypotheses. However, it is well known that more complex evolutionary scenarios are poorly described by such models. Further, even when evolution proceeds in a tree-like manner, analysis of the data may not be best served by using methods t...

متن کاملPhylogenetic studies on the origin of HIV-1
In 1999, Edward Hooper proposed that the human inmunodeficiency virus type 1 (HIV-1) could have originated in the bathes of live oral polio vaccine (OPV). He claimed that this vaccine was produced in chimpanzee kidney epithelial cell cultures rather than in monkey kidney cell cultures, as stated by the producers of OPV at the Winstar Institute in Philadelphia. The vaccine was applied to about o...
متن کاملPhylogenetic relationships of Auriculoscypha based on ultrastructural and molecular studies.
The phylogeny of Auriculoscypha anacardiicola, an associate of scale insects in India, is investigated using subcellular characters and MP and Bayesian analyses of combined nuLSU-rDNA, nuSSU-rDNA and 5.8S rDNA sequence data. It has simple septa with a pulley-wheel-shaped pore plug, which is diagnostic of phytoparasitic members of the Pucciniomycetes, and hyphal wall break on branching, a phenom...
متن کاملPhylogenetic studies on the synaptic vesicle glutamate transport system.
The ATP-dependent uptake of glutamate into synaptic vesicles isolated form mammalian brains is well characterized. Glutamate uptake requires an electrochemical proton gradient, is specific for glutamate over other amino acids, and is stimulated by chloride. To determine whether these characteristics are fundamental to the vesicular uptake system, vesicles were isolated from the brain and centra...
