Abstract
Chloroplast DNAs of higher plants have been found to contain two chloroplast ribosomal RNA genes. The base sequences of these chloroplast ribosomal RNA genes in chloroplast DNAs have been studied by molecular hybridization. The results have shown that these genes have undergone little divergence in the evolution of either monocotyledonous or dicotyledonous plants.
摘要
已发现高等植物的叶绿体DNA含有两个叶绿体核糖体RNA基因。通过分子杂交研究了叶绿体DNA中这些叶绿体核糖体RNA基因的碱基序列。结果表明，这些基因在单子叶植物或双子叶植物的进化过程中几乎没有发生分歧。
