Bacteriophages and plasmids drive horizontal gene transfer (HGT) in bacteria. Phage-plasmids (P-Ps) are hybrids of plasmid and phages. Pfeifer and Rocha recently demonstrated that P-Ps can serve as intermediates in gene exchanges between these two types of elements, identified categories of preferentially transferred genes, and reconstructed gene flows involving phage P1-like P-Ps.

探索噬菌体质粒在基因转移中的作用

噬菌体和质粒驱动细菌中的水平基因转移（HGT）。噬菌体质粒（P-Ps）是质粒和噬菌体的杂合体。 Pfeifer 和 Rocha 最近证明，P-Ps 可以作为这两类元件之间基因交换的中间体，确定了优先转移基因的类别，并重建了涉及噬菌体 P1 样 P-Ps 的基因流。
