Abstract

Diploid Saccharomyces cerevisiae strains normally sporulate to produce tetrahedral unordered asci containing four spores (tetrads). We report that when newly formed zygotes are subjected to the same sporulation conditions, they form predominantly linear ordered tetrads. We show that the two spores from each end of such a linear tetrad invariably contain nonsister centromeres. Spore viability, recombination and independence of centromere segregation appear unaffected.

摘要

二倍体酿酒酵母菌株通常通过减数分裂产生含有四个孢子（四分体）的四面体无序子囊。我们报告说，当新形成的受精卵受到相同的孢子形成条件时，它们主要形成线性有序的四分体。我们表明，这种线性四分体每一端的两个孢子都始终包含非姐妹着丝粒。孢子活力、重组和着丝粒分离的独立性似乎不受影响。
