Bacteria have evolved systems dedicated to interbacterial competition. Here we highlight defenses utilized by Gram-negative cells against type VI secretion system (T6SS)-wielding competitors, including physical barriers, genetically encoded antidotes, and stress responses. Further investigation of specific and general defenses will reveal the interbacterial selective pressures impacting bacterial survival in nature.

针对 VI 型分泌系统的细菌防御

细菌已经进化出专用于细菌间竞争的系统。在这里，我们重点介绍了革兰氏阴性细胞对 VI 型分泌系统 (T6SS) 使用竞争对手的防御，包括物理屏障、基因编码的解毒剂和压力反应。对特定和一般防御的进一步研究将揭示影响自然界细菌存活的细菌间选择压力。
