A new study reports that phage-inducible chromosomal islands (PICIs) are hotspots of defence systems against phages, other PICIs and plasmids. This discovery highlights how competition between mobile genetic elements shapes bacterial defence gene repertoires and helps to better understand how defence systems are exchanged among bacteria.
一项新的研究报告称,噬菌体可诱导染色体岛(PICIs)是防御噬菌体、其他 PICIs 和质粒的防御系统的热点。这一发现强调了移动遗传元件之间的竞争如何塑造细菌防御基因库,并有助于更好地理解防御系统在细菌之间是如何交换的。
