The use of biological inputs is an interesting approach to optimize crop production and reduce the use of chemical inputs. Understanding the chemical communication between bacteria and plants is critical to optimizing this approach. Recently, we have shown that (.) can improve both nitrogen supply and yield in pea. Here, we used biochemical methods and untargeted metabolomics to investigate the chemical dialog between and pea. We also evaluated the metabolic capacities of by metabolic profiling. Our results showed that peas release a wide range of hexoses, organic acids, and amino acids during their development, which can generally recruit and select fast-growing organisms. In the presence of , a more specific pattern of these molecules took place, gradually adapting to the metabolic capabilities of the bacterium, especially for pentoses and flavonoids. In turn, is able to produce several compounds involved in cell differentiation, biofilm formation, and quorum sensing to shape its environment, as well as several molecules that stimulate pea growth and plant defense mechanisms.
使用生物投入物是优化作物生产和减少化学投入物使用的一种有趣方法。了解细菌与植物之间的化学通讯对于优化这种方法至关重要。最近，我们已经表明（.）可以提高豌豆的氮供应和产量。在此，我们使用生化方法和非靶向代谢组学来研究（.）与豌豆之间的化学对话。我们还通过代谢谱分析评估了（.）的代谢能力。我们的结果表明，豌豆在其发育过程中会释放多种己糖、有机酸和氨基酸，这些物质通常可以招募和选择快速生长的生物体。在（.）存在的情况下，这些分子会呈现出更特定的模式，逐渐适应细菌的代谢能力，尤其是对于戊糖和黄酮类化合物。反过来，（.）能够产生几种参与细胞分化、生物膜形成和群体感应以塑造其环境的化合物，以及几种刺激豌豆生长和植物防御机制的分子。
