Core Insights - The research reveals the intricate relationship between plant roots and soil microorganisms, focusing on how roots guide microbial colonization and the molecular mechanisms involved [4][5][8] Group 1: Research Findings - The study published in the journal "Science" uncovers the "settlement map" of root-associated microorganisms and decodes the "molecular code" controlling root-microbe interactions [4][5] - The research team utilized plant seedling root systems as a model, employing fluorescently labeled live microorganisms and high-resolution imaging techniques to demonstrate that microbial settlement on root surfaces follows a systematic spatial distribution [5][7] - The integrity of a specific barrier in the root, known as the "Casparian strip," is crucial for maintaining this orderly microbial settlement; any disruption leads to nutrient leakage, particularly of the amino acid glutamine [5][7] Group 2: Implications for Agriculture - The study indicates that the leakage of glutamine from roots significantly influences microbial chemotaxis, thereby regulating microbial behavior such as movement and reproduction [7][8] - The findings provide a technical pathway for the precise enrichment of beneficial microbial communities in crop rhizospheres, which is essential for advancing "carbon sequestration" green agriculture [8] - This research lays a theoretical foundation for achieving agricultural green transformation under the "dual carbon" goals, highlighting its significant scientific implications [8]
