Intracellular membrane structures from 16 to 22 nm wide were found in the mycoplasma-like organisms causing carrot yellows. These structures are composed of five layers, three electron-dense and two electron-transparent. The membrane structures are situated, as a rule, in the central nucleoid zone of the cells of the mycoplasma-like organisms and may be seen to be in direct contact with the DNA fibrils. Ribosomes may be seen around the membrane structures. In this work we show the morphological connection between the membrane structures and the external elementary membrane of the mycoplasma-like organisms and also invagination of the external membrane into the cell. It is proposed that the intracellular membrane structures arise by means of invagination of the external elementary membrane and form a single system with this. This is the first instance of discovery of intracellular membrane structures in mycoplasmata.
在引起胡萝卜黄化病的类支原体生物中发现了宽度为16至22纳米的细胞内膜结构。这些结构由五层组成，三层电子致密层和两层电子透明层。膜结构通常位于类支原体生物细胞的中央核区，并且可以看到与DNA纤维直接接触。在膜结构周围可以看到核糖体。在这项工作中，我们展示了膜结构与类支原体生物的外部基本膜之间的形态学联系，以及外部膜向细胞内的内陷。有人提出，细胞内膜结构是通过外部基本膜的内陷产生的，并与之形成一个单一的系统。这是在支原体中首次发现细胞内膜结构的实例。
