Pseudomonas sp. F204 Promoted Tomato Growth and Altered Rhizosphere Bacteria Community.

ABSTRACT: Extracellular DNA (eDNA), as a potential plant autotoxin, can cause soil sickness, negatively affecting plant growth and reducing crop yield. Some microbial taxa can degrade eDNA; however, the effect of these bacteria on plant growth and rhizosphere microbial communities is unknown. In this study, eDNA-degrading bacterial strains were screened from soils, and their eDNA-degrading ability and plant-growth-promoting characteristics were tested in vitro. The effects of the most potent eDNA-degrading strain on tomato plant growth were assessed, and changes in the rhizosphere bacterial community were analyzed using high-throughput amplicon sequencing. Among a total of more than 600 isolated strains, Pseudomonas sp. F204 showed the strongest eDNA-degradation capacity and exhibited phosphate solu
