Ihmels2005Science.pdf and Scannell2006Nature.pdf: two concise articles dealing with events surrounding the whole genome duplication in yeast. The Ihmels et al. article reveals one way in which the yeast regulatory network probably adapted to fast growth under anaerobic conditions. The Scannel et al. article presents detailed comparative genomics and synteny analyses that allows for an unprecedented view on the fate of most genes resulting from the genome duplication.
