摘要
In budding yeast Saccharomyces cerevisiae, centromeres and telomeres are tethered to the nuclear envelope during premeiotic interphase. Immediately after cells enter meiotic prophase, chromosomes undergo global reorganization, including bouquet formation (telomere clustering), non-homologous centromere coupling, homologous pairing, and assembly/disassembly of synaptonemal complexes. These chromosome dynamics have been implicated in promoting pairing, synapsis, crossover DNA recombination and segregation between homologous chromosomes. This review discusses recent studies related to the role of small ubiquitin-like modifier (SUMO) modification in controlling the overall budding yeast chromosome dynamics during meiotic prophase.
