| description | The structure of endophytic bacteria is important to plant health and stress tolerance, but little is known about the impacts of farming systems on temporal changes in diversity of endophytic bacteria. In this study, we investigated the endophytic microbiome in rice roots under organic and conventional farming systems at the seedling and tillering stages over two consecutive cropping seasons using 16S rRNA gene sequencing. Although the composition of the microbiome was significantly influenced by a field management system, growth stage, and interaction between the two factors, the growth stage alone explained more than 40% of variance. Soil pH and organic matter content also partially influenced the endophytic bacterial community composition. In addition, through indicator species analysis and the functional profiles predicted by phylogenetic analysis, we revealed the selection force of rice roots at the tillering stage to recruit endophytes, which are beneficial to plant growth. In summary, our data show that the dynamics of rice root bacterial composition are mainly influenced by the plant growth stage. Our findings offer new insights regarding the control of the root microbiome by host plants and the influence of farming systems. |
