We determined the restriction maps and primary structures of two as yet poorly characterized regions of the mitochondrial genomes of different wild-type strains of Saccharomyces cerevisiae. These regions respectively comprised the ori1 sequence and the newly identified ori8 sequence. Ori1 and ori8, together with their flanking sequences, exhibit a large polymorphism, resulting from specific variations due to insertions or deletions of optional GC clusters at different locations. The mechanisms underlying such sequence rearrangements are discussed.
我们确定了酿酒酵母不同野生型菌株线粒体基因组中两个尚未充分表征区域的限制图谱和一级结构。这些区域分别包含ori1序列和新鉴定的ori8序列。Ori1和ori8及其侧翼序列表现出很大的多态性，这是由于不同位置的可选GC簇插入或缺失导致的特定变异所致。本文讨论了这种序列重排的潜在机制。
