Abstract
A mating between niacin and pantothenate auxotrophs of Cryptococcus neoformans gave a few prototrophic progeny that were self-fertile. These were uninuclear but contained twice as much DNA as the parental strains. Segregation of nutritional markers was observed upon sporulation. We conclude that these self-fertile strains are diploids.
摘要
新型隐球菌的烟酸和泛酸营养缺陷型菌株之间的杂交产生了一些可自交育的原养型后代。这些后代是单核的，但DNA含量是亲本菌株的两倍。在孢子形成时观察到营养标记的分离。我们得出结论，这些可自交育的菌株是二倍体。
