细菌识别亲属的能力为形成社会群体提供了一种手段。反过来,这些群体可以导致超越个人能力的合作行为。亲属识别涉及受体和识别分子之间的特异性生物化学相互作用。为了确保排除非亲属而包括亲属,识别特异性是至关重要的,并且取决于所涉及的基因座和多态性的数量。在识别和生化感知之后,常见的随后的合作行为包括生物膜形成、群体反应、发育和群集运动。虽然亲属识别是细胞相互作用的基本机制,但微生物学家才刚刚开始探索这个话题。这篇评论认为细菌亲属识别的分子和理论方面。也考虑到细菌的多样性,遗传相关性,亲属选择理论和识别机制。
The ability of bacteria to recognize kin provides a means to form social groups. In turn these groups can lead to cooperative behaviors that surpass the ability of the individual. Kin recognition involves specific biochemical interactions between a receptor(s) and an identification molecule(s). To ensure that nonkin are excluded and kin are included, recognition specificity is critical and depends on the number of loci and polymorphisms involved. After recognition and biochemical perception, the common ensuing cooperative behaviors include biofilm formation, quorum responses, development and swarming motility. Although kin recognition is a fundamental mechanism through which cells might interact, microbiologists are only beginning to explore the topic. This review considers both molecular and theoretical aspects of bacterial kin recognition. Consideration is also given to bacterial diversity, genetic relatedness, kin selection theory, and mechanisms of recognition.
