Comparison of Bacterial Diversity in the Rhizosphere of Chromolaena odorata (L.) R.M. King and H.Rob. in Different Habitats

The invasion of Chromolaena odorata (L.) R.M. King and H.Rob. affects microbial community structure, but seldom do studies focus on bacterial diversity in the rhizosphere C. from different habitats. To reveal impacts communities habitats, functional groups bacteria were compared soil collected three habitats: abandoned land, a mature eucalyptus forest (eight-years), young (one-year). In this study, 3701 OTUs (operational taxonomic units) obtained by next-generation sequencing. Simpson indexes forests significantly higher than that land. Based PCoA analysis, significant differences composition observed among Significant habitats also demonstrated biomarkers based linear discriminant analysis effect size (LEfSe) analysis. Functional prediction showed abundance nitrogen-fixing genes was greater Canonical correspondence (CCA) found biomass odorata, pH, total phosphorus main factors impacted structure. results highlight varied with invaded providing new evidence for understanding
