abstract：:In diploid Saccharomyces cerevisiae cells, bud-site selection is determined by two cortical landmarks, Bud8p and Bud9p, at the distal and proximal poles, respectively. Their localizations depend on the multigenerational proteins Rax1p/Rax2p. Many genes involved in bud-site selection were identified previously by genom...
