“…For the nonrhizosphere soils samples, the relative abundances of Fungal pathogen taxa including Fusarium incarnatum ( Ayoubi and Soleimani, 2016 ), Neopestalotiopsis clavispora ( Gilardi et al, 2019 ) and Alternaria tenuissima ( Fu et al, 2019 ) in Akihime samples were significantly higher than those in F. nilgerrensis samples ( p < 0.05) ( Figure 6A ). For the rhizosphere soil samples, the relative abundances of Fusarium incarnatum and Neopestalotiopsis clavispora in Akihime samples were significantly higher than those in F. nilgerrensis samples ( p < 0.05), while the relative abundance of Curvularia trifolii ( Zhang et al, 2022b ) was significantly lower than that in F. nilgerrensis samples ( p < 0.05) ( Figure 6B ); For the root endosphere samples, the relative abundances of Fusarium incarnatum, Rhizoctonia fragariae ( Erper et al, 2021 ), Dactylonectria pauciseptata and Dactylonectria torresensis ( Chen et al, 2021 ) in the Akihime samples were significantly higher than in the samples of F. nilgerrensis , while the relative abundances of Alternaria tenuissima, Gnomoniopsis fragariae ( Fang et al, 2011 ) were significantly lower than those in the F. nilgerrensis samples ( Figure 6C ).…”

“…At the same time, a variety of fungal pathogen taxa were detected in the samples of Akihime with higher relative abundances than F. nilgerrensis , especially in the root endosphere samples. These taxa include Fusarium incarnatum (which can cause strawberry wilt, root rot and fruit rot) ( Ayoubi and Soleimani, 2016 ), Rhizoctonia fragariae (which can cause strawberry root rot) ( Erper et al, 2021 ; Su et al, 2022 ), Dactylonectria pauciseptata , and Dactylonectria torresensis (which is associated with black root rot of strawberry) ( Chen et al, 2021 ) ( Figure 6 ). In addition, the potential bacterial pathogens Erwinia and Xanthomonas ( Expert et al, 2004 ; Timilsina et al, 2020 ) were also detected in the root endosphere samples of Akihime with higher relative abundances than in F. nilgerrensis samples.…”

Fragaria nilgerrensis is a wild strawberry species widely distributed in southwest China and has strong ecological adaptability. Akihime (F. × ananassa Duch. cv. Akihime) is one of the main cultivated strawberry varieties in China and is prone to infection with a variety of diseases. In this study, high-throughput sequencing was used to analyze and compare the soil and root microbiomes of F. nilgerrensis and Akihime. Results indicate that the wild species F. nilgerrensis showed higher microbial diversity in nonrhizosphere soil and rhizosphere soil and possessed a more complex microbial network structure compared with the cultivated variety Akihime. Genera such as Bradyrhizobium and Anaeromyxobacter, which are associated with nitrogen fixation and ammonification, and Conexibacter, which is associated with ecological toxicity resistance, exhibited higher relative abundances in the rhizosphere and nonrhizosphere soil samples of F. nilgerrensis compared with those of Akihime. Meanwhile, the ammonia-oxidizing archaea Candidatus Nitrososphaera and Candidatus Nitrocosmicus showed the opposite tendencies. We also found that the relative abundances of potential pathogenic genera and biocontrol bacteria in the Akihime samples were higher than those in the F. nilgerrensis samples. The relative abundances of Blastococcus, Nocardioides, Solirubrobacter, and Gemmatimonas, which are related to pesticide degradation, and genus Variovorax, which is associated with root growth regulation, were also significantly higher in the Akihime samples than in the F. nilgerrensis samples. Moreover, the root endophytic microbiomes of both strawberry species, especially the wild F. nilgerrensis, were mainly composed of potential biocontrol and beneficial bacteria, making them important sources for the isolation of these bacteria. This study is the first to compare the differences in nonrhizosphere and rhizosphere soils and root endogenous microorganisms between wild and cultivated strawberries. The findings have great value for the research of microbiomes, disease control, and germplasm innovation of strawberry.

“…The typical symptoms of diseased strawberry plants with root rot include withering, blackened fibrous roots, brown rot spots on root stems, and red or blocked main root pith [17]. The pathogens causing strawberry root rot are diverse, including species in genera Fusarium [18], Dactylonectria [19], and Phytophthora and Pythium [20]. The causal organisms can vary among strawberry production regions.…”

Strawberry plants and fruits are vulnerable to infections by a broad range of pathogens and pests. However, knowledge about the epidemiology of pathogens causing strawberry diseases is limited. In this study, we analyzed Fusarium commune, a major fungal pathogen causing strawberry root rot, from diseased strawberry root tissues in southcentral China. A total of 354 isolates were obtained from 11 locations that spanned about 700 km from both south to north and east to west. Multilocus genotypes of all isolates were obtained using seven polymorphic simple sequence repeat markers developed in this study. Our analyses revealed significant genetic diversity within each of the 11 local populations of F. commune. STRUCTURE analysis revealed that the optimal number of genetic populations for the 354 strains was two, with most local geographic populations containing isolates in both genetic clusters. Interestingly, many isolates showed allelic ancestry to both genetic clusters, consistent with recent hybridization between the two genetic clusters. In addition, though alleles and genotypes were frequently shared among local populations, statistically significant genetic differentiations were found among the local populations. However, the observed F. commune population genetic distances were not correlated with geographic distances. Together, our analyses suggest that populations of F. commune causing strawberry root rot are likely endemic to southcentral China, with each local population containing shared and unique genetic elements. Though the observed gene flow among geographic regions was relatively low, human activities will likely accelerate pathogen dispersals, resulting in the generation of new genotypes through mating and recombination.
