BACKGROUND The budding yeast Saccharomyces cerevisiae can bud in two spatially programmed patterns: axial or bipolar. In the axial budding pattern, cells polarize and divide adjacent to the previous site of cell separation, in response to a cell-division remnant, which includes Bud3p, Bud4p and septin proteins. This paper investigates the role of an(More)
An ectopic recombination system using ura3 heteroalleles varying in size from 80 to 960 bp has been used to examine the effect of substrate length on spontaneous mitotic recombination. The ura3 heteroalleles were positioned either on nonhomologous chromosomes (heterochromosomal repeats) or as direct or inverted repeats on the same chromosome(More)
BACKGROUND Yeast cells polarize, bud, and divide in either of two genetically programmed patterns: axial or bipolar. The Saccharomyces cerevisiae gene BUD1 (also known as RSR1) encodes a Ras-related GTPase critical for selection of a bud sites in these patterns. To distinguish between possible mechanisms of Bud1p action, we have examined the function and(More)
