In this study, we revealed that the variation in rhizosphere and root endosphere microbial assemblage between host plant ecotypes contribute to their differential abilities to withstand cadmium (Cd) stressors. Furthermore, our study found that phenolic compounds, such as benzenoids and flavonoids, could function as both essential carbon sources and semiochemicals, thereby contributing to the assemblage of rhizosphere microbiome to resist Cd stress. Our findings provide new insights into the mechanisms that drive the differential assemblage of rhizosphere and root endosphere microbiomes to enhance plant growth under abiotic stress.
在这项研究中，我们揭示了宿主植物生态型之间根际和根内微生物组合的变化，这有助于它们对镉（Cd）胁迫因子的不同耐受能力。此外，我们的研究发现，酚类化合物，如苯类和类黄酮，可以作为必需的碳源和半化学物质，从而有助于根际微生物组的组合来抵抗 Cd 胁迫。我们的发现为驱动根际和根内微生物组的差异组合以增强植物在非生物胁迫下生长的机制提供了新的见解。
