Abstract

The ulstrastructural study on Porphyridium aerugineum showed vesicles in the peripheral cytoplasm which contain fibrous material similar in appearance to the cell sheath. In most respects the morphology of P. aerugineum, a freshwater form, is very similar to that of P. cruenturn, a marine species. However, there is a marked difference in the shape of the phycobilisomes which are attached to the chloroplast lamellae. In P. cruentum the phycobilisomes are always spherical or oblate, whereas in P. aerugineum they are disk shaped. The possibility is considered that the shape of the phycobilisomes may be determined by the phycoerythrin and phycocyanin content.

摘要

对铜绿紫球藻的超微结构研究表明，其外周细胞质中有囊泡，囊泡内含有外观与细胞鞘相似的纤维状物质。在大多数方面，淡水种类的铜绿紫球藻的形态与海生种类的紫球藻非常相似。然而，附着在叶绿体片层上的藻胆体形状存在显著差异。在紫球藻中，藻胆体总是球形或扁球形，而在铜绿紫球藻中它们是盘状的。有人认为藻胆体的形状可能由藻红蛋白和藻蓝蛋白的含量决定。
