Abstract
Mutants of Saccharomyces cerevisiae capable of growth on a minimal medium supplemented with ureidosuccinic and glutamic acids have been isolated from a pyrimidineless strain. One of these mutants consistently yielded a non-Mendelian meiotic segregation. Moreover, the mitotic transmission of the mutation was very high. It is suggested that the mutation is nonchromosomal and could be mitochondrial. However, this mutation behaves very differently from other mitochondrial mutations.
摘要
已从一个嘧啶缺陷型菌株中分离出能够在添加了脲基琥珀酸和谷氨酸的基本培养基上生长的酿酒酵母突变体。这些突变体之一始终产生非孟德尔式减数分裂分离。此外，该突变的有丝分裂传递率非常高。有人认为该突变是非染色体的，可能是线粒体的。然而，这种突变的行为与其他线粒体突变非常不同。
