A question regarding whether Si enhances the resistance of PBW is still unclear. Here, an in vitro <i>R. solanacearum</i> inoculation experiment was conducted to study the effects of Si application on the disease severity and phenotype of peanuts, as well as the microbial ecology of the rhizosphere. Results revealed that Si treatment significantly reduced the disease rate, with a decrement PBW severity of 37.50% as compared to non-Si treatment. The soil available Si (ASi) significantly increased by 13.62-44.87%, and catalase activity improved by 3.01-3.10%International journal of molecular sciencesSilicon Application for the Modulation of Rhizosphere Soil Bacterial Community Structures and Metabolite Profiles in Peanut under <i>Ralstonia solanacearum</i> Inoculation.PMC996096232001442 and 32172051CARS-132020B020219003 and 2022B0202060004R2020PY-JX004, R2020PY-JG005 and R2021PY-QY0032019KJ136-022022B02020600042021A05050300472020A1515010021 and 2021A1515010811202104TD321720512021012021M70089520220120200503R2020PY-JX0043200144220171BBF60036R2021PY-QY0032020A15150100212021A1515010811R2020PY-JG0052022010102812020B020219003Liu HDu PLi HLiang XDeng QHuang LLi SWang RHong YChen XGangurde SSChen RLu QFan CfalseSilicon Application for the Modulation of Rhizosphere Soil Bacterial Community Structures and Metabolite Profiles in Peanut under <i>Ralstonia solanacearum</i> Inoculation.Silicon (Si) has been shown to promote peanut growth and yield, but whether Si can enhance the resistance against peanut bacterial wilt (PBW) caused by <i>Ralstonia solanacearum</i>, identified as a soil-borne pathogen, is still unclear.
