重要的是，试图了解细菌的细菌发生考虑到基本的细菌特性，如细胞被膜的组成和组织。几个著名的系统发育研究已经假设绿弯菌门成员的细胞被膜是“革兰氏阴性”的（二胚层，即由内质膜和外膜定义），其中一些研究已经将导致现存绿弯菌的分支放置在细菌系统发育树的根部附近。这封信件总结了令人信服的证据，表明绿弯藻实际上是单胚层的，即只有一个细胞膜。这一结论的系统发育的影响进行了讨论。回顾的数据也揭示了有趣的光蛋白分泌系统在diderm细菌的分布。
It is important that attempts to understand bacterial phylogeny take into account fundamental bacterial characteristics such as cell envelope composition and organization. Several prominent phylogenetic studies have assumed that the cell envelopes of members of the phylum Chloroflexi are 'gram-negative' (diderm, i.e. defined by both an inner plasma membrane and an outer membrane) and some of these studies have placed the branch leading to the extant Chloroflexi near the root of the bacterial phylogenetic tree. This Correspondence summarizes the compelling evidence that the Chloroflexi are in fact monoderm, i.e. have only a single cellular membrane. The phylogenetic implications of this conclusion are discussed. The data reviewed also shed interesting light on the distribution of protein secretion systems in diderm bacteria.
