细菌群体感应（QS）机制在细菌种群的正常运行和生态适应性中起着至关重要的作用。许多关键的生理过程以QS依赖的方式由自诱导物调节，如许多革兰氏阴性细菌中的N-酰基高丝氨酸内酯（AHLs）。此外，细菌与真核宿主之间的相互作用也可以由AHLs调节。由于不同的阿勒分子对植物的积极作用，这些机制受到了广泛的关注。这种积极影响包括促进生长和诱导抗性，与细菌阿勒分子与动物之间相互作用中观察到的相当负面的影响形成鲜明对比。直到最近，我们才开始了解植物对阿勒分子反应的分子机制。本文综述了该领域的最新研究进展。第一部分概述了细菌群体感应的各个方面。随后，我们重点关注AHL对植物生长和AHL启动的影响，这是基于AHL群体感应分子的王国间相互作用中最为人所知的现象之一。最后，我们讨论了了解细菌-植物相互作用对未来农业应用的潜在好处。
Bacterial quorum sensing (QS) mechanisms play a crucial role in the proper performance and ecological fitness of bacterial populations. Many key physiological processes are regulated in a QS-dependent manner by auto-inducers, like the N-acyl homoserine lactones (AHLs) in numerous Gram-negative bacteria. In addition, also the interaction between bacteria and eukaryotic hosts can be regulated by AHLs. Those mechanisms gained much attention, because of the positive effects of different AHL molecules on plants. This positive impact ranges from growth promotion to induced resistance and is quite contrasting to the rather negative effects observed in the interactions between bacterial AHL molecules and animals. Only very recently, we began to understand the molecular mechanisms underpinning plant responses to AHL molecules. In this review, we gathered the latest information in this research field. The first part gives an overview of the bacterial aspects of quorum sensing. Later we focus on the impact of AHLs on plant growth and AHL-priming, as one of the most understood phenomena in respect to the inter-kingdom interactions based on AHL-quorum sensing molecules. Finally, we discuss the potential benefits of the understanding of bacteria-plant interaction for the future agricultural applications.
