We have observed partial heterokaryon-incompatibility reactions in combinations of field isolates of A. nidulans. We have demonstrated that partial heterokaryon incompatibility is genetically controlled by genes (partial-het genes) operating in the same manner as the previously-described het genes. Our results also reveal that partial-het genes can act additively in causing heterokaryon incompatibility and that partial heterokaryon incompatibility is not a barrier to the horizontal transfer of a mitochondrial marker. These results add to the growing body of evidence that vegetative-incompatibility reactions are not an absolute barrier to horizontal gene flow.
我们在构巢曲霉的田间分离株组合中观察到了部分异核体不相容反应。我们已经证明，部分异核体不相容是由基因（部分het基因）遗传控制的，这些基因的作用方式与先前描述的het基因相同。我们的结果还表明，部分het基因在导致异核体不相容方面可以累加作用，并且部分异核体不相容并不是线粒体标记水平转移的障碍。这些结果进一步增加了越来越多的证据，即营养体不相容反应并非水平基因流动的绝对障碍。
