中文摘要:
      亲缘识别是细菌细胞间竞争与合作的前提和基础。细菌通过亲缘识别分辨自我细胞和非自我细胞;非同类的细菌细胞相互分离或被排除,而亲缘种群内的细菌细胞进行群体运动、生物膜和子实体形成等社会性合作行为。细菌的自我识别机制可能有助于不同亲缘类群在混杂的自然系统中的共存。近些年来,细菌亲缘识别及相互作用的机制研究工作成为热点,本文总结了近缘细菌细胞间相互识别和作用机制的研究进展。
英文摘要:
      Kin discrimination provides a means for bacterial individuals to identify self from non-self, and is thus the basis and prerequisite for the competition and cooperation among bacterial cells. By kin discrimination, competitive non-self-neighbors are separated from each other or are eliminated from self-populations, whereas the kin groups perform some exclusive social behaviors, such as social movement, biofilm formation and fruiting-body morphogenesis. Kin discrimination is thus suggested to aid the co-survival of different kin groups in nature. Recently, kin discrimination is becoming a hot spot in bacteriological studies. This review summarizes recent progresses in the mechanisms for bacterial kin discrimination and interactions.
