Abstract

The prochlorophytes, oxygenic photosynthetic prokaryotes containing chlorophylls a and b, have been put forward as descended from the organisms that gave rise to chloroplasts of green plants and algae by endosymbiosis, although this has always been controversial. To assess the phylogenetic position of the prochlorophyte Prochloron didemni, we have cloned and sequenced its atpBE genes. Phylogenetic inference under a range of models gives moderate to strong support for a cyanobacterial grouping rather than a chloroplast one. Possible systematic errors in this and previous analyses of prochlorophyte sequences are discussed.

摘要

原绿藻是含有叶绿素a和b的产氧光合原核生物,有人提出它们是通过内共生作用从产生绿色植物和藻类叶绿体的生物进化而来的,尽管这一观点一直存在争议。为了评估原绿藻双栖原绿藻的系统发育位置,我们克隆并测序了它的atpBE基因。在一系列模型下进行的系统发育推断为蓝细菌分组提供了中度到有力的支持,而非叶绿体分组。本文讨论了此次以及之前对原绿藻序列分析中可能存在的系统误差。
