Transposable elements in inbreeding and outbreeding populations.
Y OUNG et al. (1994) recently found that a putative transposable element (Lytl) is present at high abundance in the genomes of individuals sampled from a group of red-fruited species of Lycopersicon, and at a much lower abundance in green-fruited species of this genus. Similar or somewhat lower abundances were found in Solanum species believed to be closely related to Lycopersicon, and even low...
متن کاملOptimal Auctions for Spiteful Bidders
Designing revenue-optimal auctions for various settings is perhaps the most important, yet sometimes most elusive, problem in mechanism design. Spiteful bidders have been intensely studied recently, especially because spite occurs in many applications in multiagent system and electronic commerce. We derive the optimal auction for such bidders (as well as bidders that are altruistic). It is a ge...
متن کاملThe evolution of cytoplasmic incompatibility types: integrating segregation, inbreeding and outbreeding.
Cytoplasmic incompatibility (CI) is a reproductive incompatibility induced by maternally transmitted bacteria of the genera Wolbachia and Cardinium. In the simplest form of CI, offspring from infected males and uninfected females suffer from increased mortality. However, it has been noted that crosses between males and females carrying different strains of infection are often also incompatible....
متن کاملPromoter Elements Regulate Cytoplasmic mRNA Decay
Promoters are DNA elements that enable transcription and its regulation by trans-acting factors. Here, we demonstrate that yeast promoters can also regulate mRNA decay after the mRNA leaves the nucleus. A conventional yeast promoter consists of a core element and an upstream activating sequence (UAS). We find that changing UASs of a reporter gene without altering the transcript sequence affects...
