Plants generate a wide variety of organic components during their different growth phases. The majority of those compounds have been classified as primary and secondary metabolites. Secondary metabolites are essential in plants' adaptation to new changing environments and in managing several biotic and abiotic stress. It also invests some of its photosynthesized carbon as secondary metabolites to establish a mutual relationship with soil microorganisms in that specific niche. As soil harbors both pathogenic and beneficial microorganisms, it is essential to identify some specific metabolites that can discriminate beneficial and pathogenic ones. Thus, a detailed understanding of metabolite's architectures that interact with beneficial microorganisms could open a new horizon of ecology and agricultural research. Flavonoids are used as classic examples of secondary metabolites in this study to demonstrate recent developments in understanding and realizing how these valuable metabolites can be controlled at different levels. Most of the research was focused on plant flavonoids, which shield the host plant against competitors or predators, as well as having other ecological implications. Thus, in the present review, our goal is to cover a wide range of functional and signalling activities of secondary metabolites especially, flavonoids mediated selective cross-talk between plant and its beneficial soil microbiome. Here, we have summarized recent advances in understanding the interactions between plant species and their rhizosphere microbiomes through root exudates (flavonoids), with a focus on how these exudates facilitate rhizospheric associations.

植物在其不同生长阶段会产生多种有机成分。这些化合物大多被归类为初级和次级代谢产物。次级代谢产物对于植物适应新的变化环境以及应对多种生物和非生物胁迫至关重要。它还将部分光合作用产生的碳作为次级代谢产物，以在特定生态位与土壤微生物建立相互关系。由于土壤中既有致病微生物也有有益微生物，因此识别一些能够区分有益和致病微生物的特定代谢产物至关重要。因此，详细了解与有益微生物相互作用的代谢产物结构，可能会为生态学和农业研究开辟新的视野。在本研究中，黄酮类化合物被用作次级代谢产物的经典例子，以展示在理解和实现如何在不同水平控制这些有价值的代谢产物方面的最新进展。大多数研究集中在植物黄酮类化合物上，它们保护宿主植物免受竞争者或捕食者的侵害，同时还具有其他生态意义。因此，在本综述中，我们的目标是涵盖次级代谢产物尤其是黄酮类化合物介导的植物与其有益土壤微生物群落之间选择性相互作用的广泛功能和信号活动。在这里，我们总结了通过根系分泌物（黄酮类化合物）理解植物物种与其根际微生物群落之间相互作用的最新进展，重点是这些分泌物如何促进根际关联。
