金针菇杂合菌株子实体颜色遗传分析

将可以单核出菇的黄色单核体与不同白色单核体配对杂交获得双核体,通过控制栽培条件和环境,观察不同组合杂交菌株在相同环境中的子实体的颜色,同时测量双核子实体菌柄基部深色部分占整个菌柄的比例,结果发现不同的黄色单核和同样白色单核组成的双核子实体颜色表达中存在着差异,且不同的白色核对颜色表达的贡献不同,证实了白色金针菇单核体中也存在着不同的等位基因,金针菇双核子实体的颜色受到两个亲本核的共同调控。

Genetic Analysis of Fruit Body Color in a Hybrid Strain of Flammulina velutipes

A series of hybrid Flammulina velutipes dikaryons were obtained by crossing yellow and white monokaryons. The color of fruit bodies generated from these dikaryons, and the ratio between dark-colored stipe regions and the entire stipe of individual fruit bodies, were determined. Our data suggest that the expression of fruit body color in the hybrid dikaryons was under the control of factors present in both the white and yellow parent monokaryons, and that multiple alleles exist in both white and yellow color-controlling factors.
