Abstract

Genomic islands are hotspots for horizontal gene transfer (HGT) in bacteria, but, for Prochlorococcus, an abundant marine cyanobacterium, how these islands form has puzzled scientists. With the discovery of tycheposons, a new family of transposons, Hackl et al. provide evidence for elegant new mechanisms of gene rearrangement and transfer among Prochlorococcus and bacteria more broadly.

摘要

基因组岛是细菌中水平基因转移（HGT）的热点，但对于原绿球藻这种丰富的海洋蓝细菌来说，这些岛屿是如何形成的一直困扰着科学家。随着转座子新家族tycheposons的发现，哈克尔等人提供了证据，证明了原绿球藻及更广泛的细菌之间基因重排和转移的精妙新机制。
