根际是土壤和植物根系之间的界面，是一个化学复杂的环境，支持各种微生物群落的发育和生长。根际微生物群的组成是动态的，受多种生物和非生物因素的控制，包括环境参数、土壤的理化性质、植物的生物活性以及附着在根系上的植物和细菌的化学信号。分子和微生物学技术的最新进展揭示了根际生物在不同水平上的相互作用。在这篇综述中，我们阐述了决定根际植物-微生物和微生物-微生物相互作用的各种因素，重点介绍了寄主基因型和发育阶段的影响，这些因素在塑造根分泌物的性质和多样性方面起着关键作用。我们还讨论了微生物在根际定殖并通过几种直接和间接机制促进植物生长发育的一致功能群。深入了解本地微生物种群的基本结构原理和控制根际生态的关键决定因素将为开发有益微生物在可持续农业和自然恢复中的有益应用技术提供方向。
Rhizosphere, the interface between soil and plant roots, is a chemically complex environment which supports the development and growth of diverse microbial communities. The composition of the rhizosphere microbiome is dynamic and controlled by multiple biotic and abiotic factors that include environmental parameters, physiochemical properties of the soil, biological activities of the plants and chemical signals from the plants and bacteria which inhabit the soil adherent to root-system. Recent advancement in molecular and microbiological techniques has unravelled the interactions among rhizosphere residents at different levels. In this review, we elaborate on various factors that determine plant-microbe and microbe-microbe interactions in the rhizosphere, with an emphasis on the impact of host genotype and developmental stages which together play pivotal role in shaping the nature and diversity of root exudations. We also discuss about the coherent functional groups of microorganisms that colonize rhizosphere and enhance plant growth and development by several direct and indirect mechanisms. Insights into the underlying structural principles of indigenous microbial population and the key determinants governing rhizosphere ecology will provide directions for developing techniques for profitable applicability of beneficial microorganisms in sustainable agriculture and nature restoration.
