The phenotype of several erythromycin-resistant mutants of Chlamydomonas reinhardi was further characterized in terms of the electrophoretic properties of their chloroplast ribosomal proteins. In mutant ery-M2d a single protein of the large (52 S) subunit has altered properties, which probably result from a change in its primary sequence. This mutation is inherited in a Meudelian manner. In mutant ery-U1a, which is inherited in a uniparental manner, a different single protein of the 52 S subunit is altered. This change might result from a change in either the primary sequence of the protein or in some form of secondary modification. These results indicate that these two distinct genetic systems must cooperate in the production of chloroplast ribosomes.
就莱茵衣藻几种抗红霉素突变体的叶绿体核糖体蛋白的电泳特性而言，对其表型作了进一步的表征。在ery - M2d突变体中，大（52 S）亚基的一种单一蛋白质的特性发生了改变，这可能是由于其一级序列的变化所致。此突变以孟德尔方式遗传。在以单亲方式遗传的ery - U1a突变体中，52 S亚基的另一种不同的单一蛋白质发生了改变。这种变化可能是由于该蛋白质一级序列的改变或某种形式的二级修饰所致。这些结果表明，这两个不同的遗传系统在叶绿体核糖体的产生过程中必须协同作用。
