In Coprinus radiatus, a mutation at the Nic-2 locus unstable at meiosis has been previously described. Further studies have now shown that this mutation is also unstable, although with lower frequency, during vegetative growth. This 'vegetative instability', which is thermosensitive, is not a random process but an aggregative process, perhaps depending on the physiological state of the mycelium.
在辐射鬼伞中，先前已描述过在减数分裂时不稳定的Nic-2位点的突变。现在进一步的研究表明，这种突变在营养生长期间也是不稳定的，尽管频率较低。这种“营养不稳定性”是温度敏感的，不是一个随机过程，而是一个聚集过程，可能取决于菌丝体的生理状态。
