Ecological functions of the bacterial chemotaxis systems in rhizosphere microbiome

在根际微环境中，特定的土壤微生物能够利用自身独特的趋化系统感应根系分泌物，响应植物的选择性招募。细菌的趋化系统介导了植物-微生物以及微生物间相互作用，在植物对根际微生物组的选择中发挥着关键的生态学功能。综述了根际微生物组中细菌趋化系统的研究进展，从生态学的角度提出了未来针对根际细菌趋化系统的研究方向，旨在阐明根际细菌趋化系统的生态学功能，为增进理解作物根际微生物组的募集过程，以及未来农业中根际微生物组的重组构建奠定理论基础。;In the rhizosphere, specific soil microbes can sense root exudates by their unique chemotaxis systems and respond to the selective recruitment of plants. The bacterial chemotaxis systems mediate the plant-microbe and microbe-microbe interactions, playing a critical role in the recruitment and establishment of rhizosphere microbiome. This review focused on research of bacterial chemotaxis systems in rhizosphere microbiome and prospected the future research direction. The review aims to elucidate the ecological functions of the bacterial chemotaxis systems, contribute to the understanding of recruitment and establishment of rhizosphere microbiome, and provide theoretical basis for recombination and reconstruction of rhizosphere microbiome in the future.
