染色体重排包括导致DNA拷贝数增加或丢失的不平衡结构变异,以及包括拷贝数中性的易位和倒位的平衡事件,这两者都有助于生物体的表型进化。可用于模式生物酿酒酵母(Saccharomyces cerevisiae)的精密遗传测定和基因编辑工具有助于深入探索染色体重排的潜在机制。本文对S.啤酒。已经开发了几种方法来产生按需染色体重排和映射重排事件的断点。最后,我们强调了染色体重排的贡献,以推动表型进化在各种S。酿酒酵母菌株。鉴于生物体中DNA复制和重组的进化保守性,在酵母的小基因组中收集的知识可以扩展到高等真核生物的基因组。
Chromosomal rearrangements comprise unbalanced structural variations resulting in gain or loss of DNA copy numbers, as well as balanced events including translocation and inversion that are copy number neutral, both of which contribute to phenotypic evolution in organisms. The exquisite genetic assay and gene editing tools available for the model organism Saccharomyces cerevisiae facilitate deep exploration of the mechanisms underlying chromosomal rearrangements. We discuss here the pathways and influential factors of chromosomal rearrangements in S. cerevisiae. Several methods have been developed to generate on-demand chromosomal rearrangements and map the breakpoints of rearrangement events. Finally, we highlight the contributions of chromosomal rearrangements to drive phenotypic evolution in various S. cerevisiae strains. Given the evolutionary conservation of DNA replication and recombination in organisms, the knowledge gathered in the small genome of yeast can be extended to the genomes of higher eukaryotes.
