N-acyl homoserine lactones (AHLs) belong to the class of bacterial quorum sensing signal molecules involved in distance signal transduction between Gram-negative bacteria colonizers of the rhizosphere, as well as bacteria and plants. AHLs synchronize the activity of genes from individual cells, allowing the bacterial population to act as a multicellular organism, and establish a symbiotic or antagonistic relationship with the host plant. Although the effect of AHLs on plants has been studied for more than ten years, the mechanisms of plant perception of AHL signals are not fully understood. The specificity of the reactions caused by AHL indicates the existence of appropriate mechanisms for their perception by plants. In the current review, we summarize available data on the molecular mechanisms of AHL-signal perception in plants, its effect on plant growth, development, and stress resistance. We describe the latest research demonstrating direct (on plants) and indirect (on rhizosphere microflora) effects of AHLs, as well as the prospects of using these compounds in biotechnology to increase plant resistance to biotic and abiotic stresses.
N-酰基高丝氨酸内酯（AHLs）属于细菌群体感应信号分子的一类，参与根际革兰氏阴性细菌定殖者之间的远程信号转导，以及细菌和植物之间的信号转导。AHLs 使单个细胞的基因活动同步，使细菌群体能够像多细胞生物一样发挥作用，并与宿主植物建立共生或拮抗关系。尽管 AHLs 对植物的影响已经研究了十多年，但植物对 AHL 信号的感知机制仍不完全清楚。AHL 引起的反应的特异性表明存在适当的机制来感知它们。在当前的综述中，我们总结了关于植物中 AHL 信号感知的分子机制、它对植物生长、发育和抗逆性的影响的现有数据。我们描述了最新的研究，证明了 AHLs 的直接（对植物）和间接（对根际微生物区系）作用，以及利用这些化合物在生物技术中提高植物对生物和非生物胁迫的抗性的前景。
