The crucial role of rhizosphere microbes in plant growth and their resilience to environmental stresses underscores the intricate communication between microbes and plants. Plants are equipped with a diverse set of signaling molecules that facilitate communication across different biological kingdoms, although our comprehension of these mechanisms is still evolving. Small peptides produced by plants (SPPs) and microbes (SPMs) play a pivotal role in intracellular signaling and are essential in orchestrating various plant development stages. In this review, we posit that SPPs and SPMs serve as crucial signaling agents for the bidirectional cross-kingdom communication between plants and rhizosphere microbes. We explore several potential mechanistic pathways through which this communication occurs. Additionally, we propose that leveraging small peptides, inspired by plant-rhizosphere microbe interactions, represents an innovative approach in the field of holobiont engineering.
根际微生物在植物生长中的关键作用及其对环境胁迫的恢复力，凸显了微生物和植物之间错综复杂的交流。植物配备了一套多样化的信号分子，这些信号分子促进了不同生物界之间的交流，尽管我们对这些机制的理解仍在不断发展。植物（SPP）和微生物（SPM）产生的小肽在细胞内信号转导中起着关键作用，对于协调各种植物发育阶段至关重要。在这篇综述中，我们提出 SPP 和 SPM 是植物与根际微生物之间双向跨界交流的关键信号剂。我们探讨了几种可能的机制途径，通过这些途径可以实现这种交流。此外，我们还提出，借鉴植物-根际微生物相互作用中的小肽，代表了后生生物工程领域的一种创新方法。
