摘要

Plants live in association and interact with a multitude of microorganisms.The prevalent model for rhizosphere recruitment argues that factors produced by root attract the specific bacterial taxa in the rhizosphere and the more specialized bacterial taxa are further enriched within root.Here, we quantified the absolute abundance of root microbiota in Medicago and rice, which revealed that most of the dominant bacterial phyla are significantly elevated in the rhizosphere to different degrees, followed by the recruitment of specific taxa into the root, suggesting an amplificationselection model for root microbiome assembly.
