Abstract

The effects of salts of 27 elements on recombination and on the production of disomic and/or diploid spores during meiosis of Saccharomyces cerevisiae has been investigated. Be(NO3)2, MgSO4, FeSO4, CuSO4, AgNO3, Na2HAsO4 were inactive on the events studied during meiotic cell division. AuCl4, CdCl2, C4H6O4Pb, SnCl2, K2Cr2O7, RbCl induced both disomic and diploid spores. LiCl acted similarly and also affected recombination. Activity in the induction of disomic spores was shown by MnSO4, HgCl2 and SrCl2. CsCl, CaCl2, Na2MoO4, NiCl2, K2PtCl4 increased the frequency of diploid spores, while NaWO4, VOSO4, KCl, BaCl2 already increased recombination frequency. NaBiO3 showed an effect on meiotic recombination only. A decrease in the occurrence of both diploid and disomic spores was suggested by the data obtained with CoCl2.

摘要

研究了27种元素的盐对酿酒酵母减数分裂过程中重组以及二体和/或二倍体孢子产生的影响。硝酸铍、硫酸镁、硫酸亚铁、硫酸铜、硝酸银、砷酸氢二钠对减数分裂细胞分裂过程中所研究的事件无活性。四氯合金酸、氯化镉、丁二酸铅、氯化亚锡、重铬酸钾、氯化铷诱导产生二体和二倍体孢子。氯化锂作用相似且也影响重组。硫酸锰、氯化汞和氯化锶表现出诱导二体孢子的活性。氯化铯、氯化钙、钼酸钠、氯化镍、氯铂酸钾增加了二倍体孢子的频率，而钨酸钠、硫酸氧钒、氯化钾、氯化钡已经增加了重组频率。铋酸钠仅对减数分裂重组有影响。氯化钴所得数据表明二倍体和二体孢子的发生率均降低。
