Abstract

Three tandemly arranged repeats (A, B, C) of 16S and 23S rDNA, and one supplementary (S) 16S rDNA adjacent to the 16S rDNA of repeat A, are present within an 18 kbp segment of a circular 73 kbp DNA from the colourless flagellate Astasia longa. The repeat units are separated by a short region containing a 5S rRNA gene and a gene for tRNA-Val (UAC). Sequence comparisons reveal 78%, 81%, and 67% identical nucleotides of the 23S rDNA (A), the 16S rDNA (B), and the 5S rDNA (A), respectively, with the corresponding genes of the Euglena gracilis chloroplast genome. As in Euglena chloroplasts, the 3'-terminal portion of the 23S rDNA is homologous to the 4.5S rRNA gene of higher plant chloroplast genomes. These results are supportive of a common evolutionary origin for the Astasia 73 kbp DNA and the Euglena 145 kbp chloroplast DNA.

摘要

来自无色鞭毛虫长眼虫（Astasia longa）的环状73kbp DNA的18kbp片段中存在16S和23S rDNA的三个串联排列重复序列（A、B、C），以及与重复序列A的16S rDNA相邻的一个补充（S）16S rDNA。重复单元由一个包含5S rRNA基因和tRNA-Val（UAC）基因的短区域隔开。序列比较显示，23S rDNA（A）、16S rDNA（B）和5S rDNA（A）分别与纤细裸藻（Euglena gracilis）叶绿体基因组的相应基因有78%、81%和67%的相同核苷酸。与裸藻叶绿体一样，23S rDNA的3'末端部分与高等植物叶绿体基因组的4.5S rRNA基因同源。这些结果支持长眼虫73kbp DNA和裸藻145kbp叶绿体DNA有共同的进化起源。
