Effects of naked barley root rot on rhizosphere soil microorganisms and enzyme activity

Identification of Dominant Microbial Community and Diversity in Continuously Cropped Pepper Fields

“…We showed that after infection, the pepper plant's rhizosphere bacteria decreased significantly, whereas actinomycetes showed no significant changes and the number of fungi increased. These observed changes in bacteria and fungi were consistent with barley root rot (Li et al, 2017), tobacco bacterial wilt (Li et al, 2020), and banana wilt (Deng et al, 2011). An explanation for this phenomenon is that the number of pathogenic fungi in the soil suddenly increases after disease and directly competes with the resident bacteria, actinomycetes, and fungi in the soil for nutrition and space, which leads to a decline in the number of beneficial microorganisms and changes the soil from "bacterial type" to "fungal type.…”

Establishment of Residual Methods for Matrine in Quinoa Plants and Soil and the Effect on Soil Bacterial Community and Composition

“…It is easy to interfere with the confirmation of the target to varying degrees. Microorganisms are important indicators of soil ecosystem health [ 32 , 33 ] and can characterize changes in soil quality more rapidly than physical and chemical indicators in the soil. The bacterial community structure of the soil is involved in energy flow and elemental cycling in ecosystems [ 34 ], such as rhizobacteria and nitrifying bacteria [ 35 ].…”
