The rapid evolution of the HIV genome is influenced in part by host selection pressure, which may cause parallel evolution among strains under shared selection pressures. To understand the mechanisms behind HIV-host immune escape across host populations, researchers have compared signatures of positive selection pressure on HIV codons across HIV subtypes(More)
Understanding the genetic basis of natural phenotypic variation is of great importance, particularly since selection can act on this variation to cause evolution. We examined expression and allelic variation in candidate flowering time loci in Brassica rapa plants derived from a natural population and showing a broad range in the timing of first flowering.(More)
