AbstractThe genetic basis of plant local adaptation has been extensively studied, yet the interplay between local adaptation, plant genetic divergence, and the microbial community remains unclear. Our study used the restriction-site associated DNA sequencing (RAD-seq) approach to explore genetic divergence in Broussonetia papyrifera and used internal transcribed spacers (ITS) to characterize fungal community. RAD-seq results show that B. papyrifera individuals could be divided into three genotypes; this genotyping result was consistent with the classification of climate type at the sample site. Most of the 101 highly differentiated genes were related to stress resistance and the microbiome. Moreover, p-diversity results indicated that genetic divergence had a significant effect on fungal community across all compartments (P < 0.01). At genus and operational taxonomic unit (OTU) level, Mortierella, Hannaella oryzae, OTU81578 (Mortierella), and OTU1665209 (H. oryzae) were found to be the major OTUs that contribute to differences in fungal community. The properties of cooccurrence networks vary greatly among three genotypes. The results of redundancy analysis (RDA) indicated that B. papyrifera-associated fungal community was significantly related to its local adaptability. Our findings suggest that genetic divergence of 8. papyrifera is closely related to local adaptation, with significant effects on the associated fungal community, which in turn would enhance host local adaptability. This improves present understanding about the coevolution of microbial communities and the host plant. IMPORTANCE The coevolution of plants with the associated fungal community and its effect on plant adaptability are not clear, especially for native trees. This study focuses on the genetic basis of local adaptation in plants and the effect of genetic divergence of Broussonetia papyrifera on the associated fungal community. We identified genes related to the microbiome that are important for local adaptation of the host. Our results show that genetic divergence in B. papyrifera significantly affects the fungal community, which has a close connection with local adaptation. This helps us to understand the relationship between local adaptation, genetic divergence, and associated fungal communities. This study highlights the effect of plant genetic divergence on associated fungal community for native trees and establishes a close connection between this effect and local adaptability in the host. In addition, these observations lay a foundation for the research of coevolution of plants and their symbiotic microbiome through genome-wide association study (GWAS).
