根际微生物调控植物根系构型研究进展

A review of the regulation of plant root system architecture by rhizosphere microorganisms

根系构型是最重要的植物形态特征之一,具有可塑性,既由遗传因素控制,又受到许多环境因子的调控。近年的大量研究表明,根际微生物能够调控植物的根系构型,进而影响植物的一系列生理与生态过程。综述丛枝菌根真菌(AMF)、根瘤菌、植物根际促生菌(PGPR)等重要根际微生物类群对植物根系构型的调控模式以及相应的调控机理,并对进一步的研究进行了展望,旨在为今后的相关研究和实际应用提供参考。

Plant root system architecture （RSA） is one of the most important characteristics of plant morphology. RSA exhibits a plasticity that is not only controlled by genetic factors but is also regulated by diverse environmental factors. Recently, a large number studies have indicated that rhizosphere microorganisms can regulate the plant RSA, and further influence an array of plant physiological and ecological processes. This paper mainly reviews the regulation patterns and corresponding mechanisms of plant RSA mediated by the important rhizosphere microorganisms, such as arbuscular mycorrhizal fungi, rhizobia, and plant growth-promoting rhizobacteria. Future research is proposed to provide reference for related research and practical applications.
