The nucleotide sequences of the 5 S ribosomal RNAs of the mushrooms Russula cyanoxantha, Pleurotus ostreatus, Agaricus edulis, and Auricularia auricula-judae were determined. The sequences fit in a universal five-helix secondary structure model for 5 S RNA. As in most other 5 S RNAs, some helical areas contain non-standard base pairs. A clustering method was used to reconstruct an evolutionary tree from 82 eukaryotic 5 S RNA sequences. It allows to make a choice between alternative systematic classifications for basidiomycetes and reveals that the fungal kingdom is highly polyphyletic.
测定了蓝黄红菇、糙皮侧耳、可食蘑菇和木耳的5S核糖体RNA的核苷酸序列。这些序列符合5S RNA通用的五螺旋二级结构模型。与大多数其他5S RNA一样,一些螺旋区域包含非标准碱基对。使用聚类方法从82个真核生物5S RNA序列重建进化树。这使得能够在担子菌的替代系统分类之间做出选择,并揭示真菌界具有高度的多系性。
