Although bacteria frequently live as unicellular organisms, many spend at least part of their lives in complex communities, and some have adopted truly multicellular lifestyles and have abandoned unicellular growth. These transitions to multicellularity have occurred independently several times for various ecological reasons, resulting in a broad range of phenotypes. In this Review, we discuss the strategies that are used by bacteria to form and grow in multicellular structures that have hallmark features of multicellularity, including morphological differentiation, programmed cell death and patterning. In addition, we examine the evolutionary and ecological factors that lead to the wide range of coordinated multicellular behaviours that are observed in bacteria.
虽然细菌通常以单细胞生物的形式存在，但许多细菌会在复杂的群落中度过至少一部分生命，而有些细菌则已经采用真正的多细胞生活方式并放弃了单细胞生长。这些向多细胞性的转变是由于各种生态原因而独立发生的多次进化，从而产生了广泛的表型。在这篇综述中，我们讨论了细菌在具有多细胞特征的多细胞结构中形成和生长的策略，包括形态分化、程序性细胞死亡和模式形成。此外，我们还研究了导致细菌中观察到的广泛协调的多细胞行为的进化和生态因素。
