“…For instance, certain members of bacterial genera (e.g., Curtobacterium and Pseudomonas ) as well as fungal genera (e.g., Alternaria and Penicillium ) were identified as potential pathogens for pear and apple bark ( Arrigoni et al, 2018 ). Meanwhile, Nigrospora oryzae and Plectosphaerella cucumerina were also the core fungal microbiota of G. soja , which have the potential to cause leaf spot and root rot, respectively ( Chen et al, 2019 ; Elmer et al, 2020 ). Nevertheless, it should be mentioned that although the sequences of the core microbial ASVs were identified by clustering with the known sequences from NCBI GenBank in accordance with their phylogenetic relationships ( Figures 6A , B ), it is difficult to differentiate the taxa below genus level using 16S-based profiling.…”

IntroductionThe microbiome inhabiting plant leaves is critical for plant health and productivity. Wild soybean (Glycine soja), which originated in China, is the progenitor of cultivated soybean (Glycine max). So far, the community structure and assembly mechanism of phyllosphere microbial community on G. soja were poorly understood.MethodsHere, we combined a national-scale survey with high-throughput sequencing and microsatellite data to evaluate the contribution of host genotype vs. climate in explaining the foliar microbiome of G. soja, and the core foliar microbiota of G. soja were identified.ResultsOur findings revealed that both the host genotype and environmental factors (i.e., geographic location and climatic conditions) were important factors regulating foliar community assembly of G. soja. Host genotypes explained 0.4% and 3.6% variations of the foliar bacterial and fungal community composition, respectively, while environmental factors explained 25.8% and 19.9% variations, respectively. We further identified a core microbiome thriving on the foliage of all G. soja populations, including bacterial (dominated by Methylobacterium-Methylorubrum, Pantoea, Quadrisphaera, Pseudomonas, and Sphingomonas) and fungal (dominated by Cladosporium, Alternaria, and Penicillium) taxa.ConclusionOur study revealed the significant role of host genetic distance as a driver of the foliar microbiome of the wild progenitor of soya, as well as the effects of climatic changes on foliar microbiomes. These findings would increase our knowledge of assembly mechanisms in the phyllosphere of wild soybeans and suggest the potential to manage the phyllosphere of soya plantations by plant breeding and selecting specific genotypes under climate change.
