Abstract
Invasive plants have become an environmental issue of common global concern, posinga significant threat to environmental protection. As one of the invasive species, Flaveria bidentis (L.) Kunt has seriously affected the ecological preservation of the invaded area. In recent years, most research on the invasion of F. bidentis to soil ecosystems has focused on soil nutrient content, bacterial community diversity, and fungal community diversity. In comparison, the effect of the invasive plant on the Yellow River Delta was still unknown. We obtained the soil microorganisms under F. bidentis invasion in the present study in the YRD. Our result showed that the Proteobacteria, Acidobacteriota, Gemmatimonadota, and Actinobacteriota were dominant in rhizosphere soil bacteria samples of F. bidentis (HDJ) and the bulk soils samples of F. bidentis BSK groups; the Ascomycota and Basidiomycota were dominant in HDJ and BSK groups. The OUT results showed that 1418 bacterial OTUs and 1192 fungal OTUs were observed in all the groups. The SourceTracker analysis found that the average 49.27% bacterial community of BKS groups was from HDJ groups, and a middle 62.2% fungal community of BKS groups was from HDJ. Compared with the bacteria, the F. bidentis invasion had a more significant effect on the fungal community of the invasive soil. In conclusion, our results explored the bacterial and fungal community of invasive species in the rhizosphere and non-rhizosphere soils, providing new insight into strengthening biodiversity protection in the YRD.
