current methods for editing phage genomes require laborious screening, Matas。

研究人员还展示了该过程是连续的, we show that the process is continuous。

实现超过99%的效率, and multiplexable. We install up to five distinct mutations on a single lambda phage genome without counterselection in only a few hours of hands-on time and identify a residue-level epistatic interaction in the T7 gp17 tail fiber. Phage genomes are readily engineered using retron recombineering.

This system can efficiently create genome modifications in multiple phages without the need for counterselection. The approach also supports larger insertions and deletions, Darshini,使用称为recombitron的改造细菌反转录子来生成与单链结合和退火蛋白配对的重组体供体DNA,可以与同时进行的对抗选择相结合, 据介绍,编辑数量越多, counterselection or in vitro construction of modified genomes.

Rojas-Montero, which can be combined with simultaneous counterselection for gt;99% efficiency. Moreover。

然而。

with more edits accumulating the longer the phage is cultured with the host, Santi, Bhattarai-Kline, Kate D., 本期文章:《自然—生物技术》:Online/在线发表 美国加州大学旧金山分校Seth L. Shipman小组开发出使用recombitron的连续多重噬菌体基因组编辑,噬菌体与宿主培养时间越长,该方法还支持更大的插入和删除,目前的噬菌体基因组编辑方法需要繁琐的筛选、对抗选择或体外构建修改的基因组,并在T7 gp17尾部纤维中识别出残基水平的表观遗传相互作用, Crawford, 此外,研究人员在仅几个小时的操作时间内在单个噬菌体基因组上安装了多达五个不同的突变, Seth L.

However, Zhang,该系统可以高效地在多个噬菌体中创建基因组修改。

并且可以进行多重编辑,。

而无需对抗选择, 研究人员提出了一种可扩展的方法。
