作者调查的基因组属性的进化异常。Wolinella succinogenes是一种专性寄生菌生活在反刍动物营养非常丰富，homeostatically稳定的环境。因此，人们可能会合理地期望它只有少数的转导系统和一个小基因组来生存。然而，这种生物，似乎有一个庞大的基因组和一个大阵列的换能器系统。作者量化这些系统，并不能提供任何令人信服的论据，为什么他们已经进化以外的有机体可能已经恢复到这种存在，从一个更苛刻的环境。它包括在我们的讨论只是作为一个说明异常。本文提供了大量的背景下，相关的概念的内部结构和功能组织的典型细胞。这是特别有用的介绍一些目前的概念有关转导机制的概述和许多具体的例子引用本文。

The authors investigate the genomic properties of something of an evolutionary anomaly. Wolinella succinogenes is an obligate ruminant bacterial parasite living in a very nutrient rich and homeostatically stable environment. One might therefore reasonably expect it to have only a few transduction systems and a small genome to survive. This organism however, appears to have a huge genome and a large array of transducer systems. The authors quantify these systems and are unable to offer any convincing arguments as to why they have evolved other than the organism may have reverted to this existence from a more demanding environment. It is included in our discussions simply as an illustrative anomaly. This article provided a great deal of the background in terms of the concepts related to the internal structural and functional organisation of the typical cell. It was particularly useful in presenting some of the current concepts relating to transduction mechanisms in overview and many of the specific examples cited were taken from this paper.
