The mechanism of promoting rhizosphere nutrient turnover for arbuscular mycorrhizal fungi attributes to recruited functional bacterial assembly

Abstract: Symbiosis with arbuscular mycorrhizal (AM) fungi improves plant nutrient capture from the soil, yet there is limited knowledge about the diversity, structure, functioning, and assembly processes of AM fungi‐related microbial communities. Here, 16S rRNA gene sequencing and metagenomic sequencing were used to detect bacteria in the rhizosphere of Lotus japonicus inoculated with and without AM fungi, and the L. japonicus mutant ljcbx (defective in symbiosis) inoculated with AM fungi in southern grassland soil.

“…The microbial species recruited in the mycorrhizal rhizosphere of maize were likely to help maize to obtain phosphate through the mycorrhizal pathway. AMF symbiosis changed exudates released into the rhizosphere soil to attract microorganisms, probably resulting in the directional enrichment of some special microorganisms ( Jiang et al., 2021 ; Ma et al., 2022 ; Xu et al., 2023a ; Xu et al., 2023b ). The changes of rhizosphere bacteria in AMF-colonized Mut maize may result from the reduced AMF colonization rate, which might monitor changes of exudates in soil, and in turn, influence the recruitment of bacteria.…”

“…The rhizosphere inhabited by many microorganisms has been defined as the second plant genome ( Kuzyakov and Razavi, 2019 ; Vetterlein et al., 2020 ). AMF symbiosis alters root exudates ( Zhang et al., 2022 ; Xu et al., 2023a ; Xu et al., 2023b ), resulting in the rhizosphere microbiome being altered and stimulating soil nutrient turnover ( Zhang et al., 2018a ). AMF has been reported to influence the rhizosphere microbial composition involved in the decomposition of organic materials ( Herman et al., 2012 ; Nuccio et al., 2013 ).…”

“…Our results suggested that the average content of available phosphorus, available potassium, nitrate, and ammonium was higher in rhizosphere soil than in bulk soil. This could be explained by the fact that the enrichment of a large number of functional microbial groups related to nutrient mineralization in the rhizosphere soil, through which organic matter was metabolized and converted into mineral elements [35,36]. Compared with the unfertilized treatment group, consecutive fertilization treatment increased the content of nitrate, available phosphorus, and available potassium in rhizosphere soil.…”

“…Plant growth-promoting bacteria (PGPB) help plants grow by supplying nitrogen, phosphorus, and potassium, and hormones [12]. Screening of PGPB from natural environments has been conducted in many fields [12][13][14]. Bamboo forests growth-promoting bacteria have received less attention than PGPB.…”
