Abstract

The 5S rRNA nucleotide sequence of Thermoactinomyces vulgaris was determined and compared with published sequences of representative Gram-positive bacteria. The primary and secondary structure of the sequence is of the type characteristic of Gram-positive bacteria that have DNA with a low proportion of guanine plus cytosine. It was evident from the phylogenetic trees that T. vulgaris has little in common with actinomycetes but is related to the genus Bacillus, showing a moderately high relationship with B. stearothermophilus. The taxonomic implications of these relationships are discussed and an emended description of the family Bacillaceae is given.

摘要

测定了嗜热放线菌的5S rRNA核苷酸序列，并与已发表的代表性革兰氏阳性菌序列进行了比较。该序列的一级和二级结构属于革兰氏阳性菌的典型类型，这些革兰氏阳性菌的DNA中鸟嘌呤加胞嘧啶的比例较低。从系统发育树中可以明显看出，嗜热放线菌与放线菌几乎没有共同之处，但与芽孢杆菌属有关，与嗜热脂肪芽孢杆菌有中等程度的高度相关性。讨论了这些关系的分类学意义，并给出了芽孢杆菌科的修订描述。
