Het up mould unleashes a sporekiller prion
het-s/het-S incompatibility is one of only a handful of fungal heterokaryon incompatibility systems that have begun to be molecularly analysed (for a review see Saupe 2000). The spore killer phenotype also is one of only a few segregation ratio distortions that has been studied in any detail. Finally the [HET-s] prion is one of only three examples known in non-mammalian systems (for a review see Wickneret al 1999). Clearly thehet-s/het-S story intersects with several exciting areas of research that offer many opportunities for young scientists.
