摘要:
Budding yeast PDS5 is an essential gene in mitosis and is required for chromosome condensation and sister chromatid cohesion. Here we report that PDS also is required in meiosis. Pds5p localizes on chromosomes at all stages during meiotic cycle, except anaphase I. PDS5 plays an important role at first meiotic prophase. Failure in function of PDS5 causes premature separation of chromosomes. The loading of Pds5p onto chromosome requires the function of REC8, but the association of Rec8p with chromosome is independent of PDS5. Mutant analysis and live cell imaging indicate that PDS5 play a role in meiosis II as well.
