Metabolism is the underpinning force that sustains life. Within the rhizosphere it is a cyclic process, with substrates flowing between different compartments of the complete soil-plant-microbe system. The physiochemical and structural environment of the rhizosphere is shaped by a combination of plant genotype and soil type, both of which strongly impact the microbial community structure. External influences such as seasonality, the degree of water saturation and anthropomorphic inputs also play a role. Together these factors influence the flux of metabolites through the rhizosphere community, which in turn impacts on plant growth, development and disease. In this review, the focus is on metabolism within the bacterial population of the rhizosphere, since this group covers every type of plant-microbe interaction: from obligately symbiotic to destructively pathogenic, and includes those have little or no direct impact on plant hosts. The focus of the review is on metabolic functions that occur in the rhizosphere either during bacteria-plant interactions or bacteria-bacteria interactions and mainly covers heterotrophic metabolism of organic substrates. As such, many of the autotrophic (and phototrophic) reactions of inorganic compounds are not included.

你就是你可以找到吃的东西：根际的细菌代谢。

新陈代谢是维持生命的基础力量。在根际，它是一个循环过程，基质在完整的土壤-植物-微生物系统的不同部分之间流动。根际的理化和结构环境是由植物基因型和土壤类型共同决定的，这两者都强烈影响着微生物群落结构。季节性、水饱和度和拟人输入等外部影响也发挥了作用。这些因素共同影响代谢物在根际群落中的流动，进而影响植物的生长、发育和疾病。在这篇综述中，重点是根际细菌种群内的新陈代谢，因为该组涵盖了每种类型的植物-微生物相互作用：从专性共生到破坏性致病，包括对植物宿主几乎没有或没有直接影响的那些。综述的重点是在细菌-植物相互作用或细菌-细菌相互作用期间发生在根际的代谢功能，主要涵盖有机底物的异养代谢。因此，不包括无机化合物的许多自养（和光养）反应。
