共分析了采自全国各地的73株赤霉菌,发现该菌在我国各地普遍以异核体性存在。分析结果指示异核体约占69.9%,纯核体约占30.1%,在同一菌丝的不同部位遗传型不同的核分布很不均匀。以多标记的营养缺陷突变型株作为亲本,采用一种简便的方法强制合成了异核体。 A total of 73 strains of Fusarium that were collected from all over the country were analyzed and found to be heterokaryonous throughout China. The analysis indicated that about 59.9% of heterokaryons and about 30.1% of pure nucleosomes were found, and the distribution of different types of nuclei in different genotypes of the same mycelium was very uneven. Multi-labeled auxotrophic mutant strain as a parent, using a simple method to force the synthesis of heterokaryons.
