在中国湖南省发现了1个金针菇新变型,其主要特征是子实体菌盖酒粉红色,将其命名为金针菇酒粉色变型(Flammulina velutipes f.vinaceoroseolus),对其进行了形态学描述并绘制了线条图。用克隆测序的方法获得了该变型的ITS序列,并与其他金针菇菌株进行了比较,结果发现该变型同一子实体具有5种不同的ITS序列,相互之间的差别为1~13个碱基,说明该变型的形成经历了多次杂交和染色体交换。分析还表明金针菇存在丰富的种内遗传多样性。
A new variant of Flammulina velutipes was found in Hunan province, China. Its main feature is the fruiting body cap wine pink, which is named Flammulina velutipes f .vinaceoroseolus, which is morphologically described and drawn Line chart. The ITS sequence of this variant was obtained by cloning and sequencing and compared with other Flammulina velutipes strains. The results showed that there were 5 different ITS sequences in the same fruiting body, with the difference of 1 ~ 13 bases, This shows that the formation of the variant has undergone several hybridizations and chromosome exchange. The analysis also showed that Flammulina velutipes is rich in intraspecific genetic diversity.
