Chloroplast DNA was isolated and cloned from Chlorella, strain N1a, exsymbiotic with Paramecium bursaria. BamHI, SalI, KpnI and Xho I restriction fragments of the DNA were assembled into a circular map. The genome consists of approximately 120 kbp of DNA, has a G/C content of 38%, and contains only a single copy of the rRNA cistron. The rRNA cistron is small, 5000-8000 bp, and the 16S and 23S gene are separated by less than 2000 bp.
从小球藻N1a菌株（与草履虫共生）中分离并克隆了叶绿体DNA。该DNA的BamHI、SalI、KpnI和Xho I限制性片段被组装成一个环状图谱。基因组由约120kbp的DNA组成，G/C含量为38%，并且仅包含rRNA顺反子的单拷贝。rRNA顺反子较小，为5000 - 8000bp，16S和23S基因之间的间隔小于2000bp。
