Despite the importance of phages as primary drivers for bacterial evolution, phage-bacteria interactions across spatiotemporal scales in natural, agricultural settings are underexplored. With increased interest in phage-based therapies to manage bacterial pathogens, an enhanced understanding of phage genetic and functional diversity at the population level, and how this, in turn, impacts bacterial evolution and virulence, is necessary. This study presents data on the genetic similarity among Xanthomonas arboricola pv. pruni (Xap) strains isolated from different geographic locations that display different lytic phenotypes when challenged with a panel of six phage isolates collected in the same region over four decades. The minor yet significant genetic variation among this small population of Xap strains is structured by both geographic location and response to phage infection. Phage genomes are also highly similar, with conserved and diverse genomic loci that correspond to isolation year. The six phages characterized here cluster into the Kantovirinae subfamily and possibly form a new genus. Only future studies will elucidate the role of Xap and Xapφ phage genes identified here in the virulence and lysis of Xap and how these, in turn, impact bacterial spot disease outcomes. The research and tripartite pathosystem presented here provides a unique opportunity to investigate the coevolution of phage-phytobacterial pathogen-plant host in depth in an agricultural setting with the potential to monitor the rate at which phage populations contribute to bacterial genetic diversity across geographic and temporal scales.","PeriodicalId":48504,"journal":{"name":"Phytobiomes Journal","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141806409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the membership of the sorghum microbiome in response to stress has been explored, relatively little is known about how microbe-microbe networks change under water- or nutrient-limited conditions. This is important because network changes can indicate impacts on the functionality and stability of microbial communities. We performed network-based analysis on the core bacterial and archaeal community of an agronomically promising high biomass bioenergy genotype, Grassl, grown under nitrogen and water stress. Stress caused relatively minor changes in bacterial abundances within soil, rhizosphere, and endosphere communities, but led to significant changes in bacterial network structure and modularity. We found a complete reorganization of network roles in all plant compartments as well as an increase in the modularity and proportion of positive associations which potentially could represent coexistence and cooperation in the sorghum bacterial/archaeal community under stress. While stressors are often believed to be destabilizing, we found stressed networks were as or more stable than non-stressed networks likely due to their redundancy and compartmentalization. Together, these findings support the idea that both sorghum and its bacterial/archaeal community can be resilient to future environmental stressors.","PeriodicalId":48504,"journal":{"name":"Phytobiomes Journal","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141344507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We studied the impact of a plant resistance gene by analyzing the mycobiota associated with Brassica napus organs over two cropping seasons. Sampling dates coincided with key stages of the life cycle of the B. napus pathogen Leptosphaeria maculans. Leaf samples were collected at three time points in autumn and spring, and stem base samples were collected at two time points a few weeks before and at harvest. Stem residues, where L. maculans survives in the intercropping season and develops sexual reproduction, were also analyzed at four time points between the two cropping seasons. The sampling was performed on two plant genotypes, Darmor and Darmor- Rlm11, only differing by the effective resistance gene against L. maculans, Rlm11. Altogether, 419 samples were analyzed using two barcode: internal transcribed spacer (ITS) and Actin. The plant organ was shown to be the main mycobiota structuring factor, as clear-cut alternation of the species suggested that each plant organ represented a specific ecological niche. The cropping season and plant genotype also significantly influenced the community structure in lower proportions. The resistance gene contributed differently to the community structure depending on the year and the organ concerned. A significant but low impact of Rlm11 on other B. napus fungal pathogens was detected. The ITS and Actin barcodes showed similar results, but the species assignation was limited for the latter.","PeriodicalId":48504,"journal":{"name":"Phytobiomes Journal","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140970133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Management strategies for these pathogens are limited, and additional tools for their control are needed. Some fungi have shown promise for biocontrol, however, their success in the field has varied. In contrast, some fungal plant pathogens form synergistic associations with nematodes resulting in increased plant disease severity. However, how both groups of fungi change with different plant parasitic nematode abundances in the soil is underexplored. In this study, we used the soybean cyst nematode as a model to understand these changes. We sampled soil from 171 Ohio soybean fields in 2019 and 2021 and determined soybean cyst nematode abundance. We identified the fungi in the samples through amplicon sequencing of the 18S-ITS rDNA regions. Edaphoclimatic factors were used to classify samples into geographic regions to account for environmental differences between sampling locations. We hypothesized that fungal communities would be influenced by both region and soybean cyst nematode abundance. K-near neighbor analysis revealed that fungal communities follow regional patterns. We also found that soybean cyst nematode abundance was associated with changes in these communities regardless of the region. Two potential nematophagous fungi were found to be prevalent in Ohio through core community analysis, although they were enriched when soybean cyst nematode abundance was high. Lastly, differential network analysis showed that interactions among fungal community members change when soybean cyst nematode is present in the soil. Together these results suggest that this nematode significantly shifts the fungal community composition in field soils.","PeriodicalId":48504,"journal":{"name":"Phytobiomes Journal","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140995564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we tested a series of hypotheses centered on the fungal mycobiome and bacterial microbiome of field-grown sorghum (Sorghum bicolor (L.) Moench), an emerging model crop for drought resilience, which we cultivated under arid conditions. Overall, the sorghum mycobiome and microbiome differed in composition between the exterior and interior of plant tissues, between roots and leaves, and among sorghum genotypes. We did not observe variation in fungal and bacterial endophytes among performance classes of sorghum when water was plentiful, but the root-endophytic mycobiome and microbiome both shifted markedly under water limitation, with similar shifts in composition observed among multiple plant genotypes. The root-endophytic microbiome of high-performing sorghum was especially responsive to water limitation. Network analyses suggest that water limitation did not directly remodel these root-endophytic microbiomes, such that interactions of the microbiome with the host plant – rather than interactions among microbes within the microbiome – may be the most dynamic element of change when water is limited. Overall, our study points to shifts in the prevalence of particular taxa under abiotic stress and suggests that high-performing lines may have distinctive features as substrates, or strategies for actively recruiting diverse, abundant, and distinctive microbial communities to roots under water limitation. Such findings are important in the arid lands that frame marginal agriculture today and comprise an increasing proportion of agriculture in a changing world.","PeriodicalId":48504,"journal":{"name":"Phytobiomes Journal","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140087965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effect of chitin soil amendment on lettuce growth in mineral soil remains unexplored. The effect of chitin amendment of mineral soil on lettuce growth and metabolite changes was investigated for the first time in the present study in comparison to chitin amended peat substrate. Our findings showed that chitin addition in peat substrate increased lettuce head weight by approximately 50% at harvest, whereas this increase was 30% when added to mineral soil. Targeted metabolomics analysis indicated that chitin addition affected the phenolic compounds in lettuce seedlings, but this effect varied between soil types. Moreover, untargeted metabolomics analysis suggested that using peat substrate or mineral soil had a greater influence on produced lettuce metabolites than chitin addition. Rhizobiome analysis showed that specifically Mortierellaceae family members, known for chitin degradation and plant growth promotion, significantly increased in peat substrate upon chitin treatment. In mineral soil, three bacterial genera and five fungi, including known plant growth promoting genera, were significantly more abundant upon chitin treatment but not Mortierellaceae. We assume that the observed effects primarily stem from soil physiochemical characteristics and from chitin induced alterations in rhizobiome composition, particularly the presence of Mortierellaceae members, leading to promoted lettuce growth. Despite the variability, chitin remains an environmentally friendly alternative to synthetic fertilizers in lettuce production, but its beneficial effects are dependent on rhizobiome composition, which should be considered before chitin application.","PeriodicalId":48504,"journal":{"name":"Phytobiomes Journal","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140420536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effects of targeted phage therapy on indigenous microbial community has not been fully understood. In this study, we hypothesized that phages infecting plant pathogenic bacteria play a role in modulating the microbial community in the plant rhizosphere. To explore this, we used the soil-borne plant bacterial pathogen Ralstonia pseudosolanacearum as the host bacterium and its phages as a model system in the tomato rhizosphere. The effect of phages on microbiota was compared using a narrow host range phage RpY1, and a combination of two phages (RpY2 and RpT1, termed the phage combo) with a broad host range, under the natural rhizosphere microbiota of tomato plants. Both RpY1 and phage combo altered the tomato rhizosphere microbiota. The phage combo displayed phage effects mostly in the presence of R. pseudosolanacearum. However, RpY1 affected the rhizosphere microbiota even in the absence of the host bacterium. The effect of phage RpY1 on the microbiota was further investigated in the tomato rhizosphere using a synthetic community (SynCom) mimicking the natural tomato rhizosphere microbiota. Phage RpY1 affected the microbial community structure of SynCom in the tomato rhizosphere in the absence of the host bacterium. The analyses of natural microbiota and SynCom in the tomato rhizosphere indicated an indirect effect of phage RpY1 on the microbiota. This study suggests that phage application modulates indigenous microbiota through unknown interactions with non-host bacterial members in the plant rhizosphere.","PeriodicalId":48504,"journal":{"name":"Phytobiomes Journal","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140421175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our research examines the impact of multi generation post-flowering drought stress on the wheat seed endophytic fungal community. Understanding how wheat seed fungal communities respond to drought stress over several generations can improve our knowledge of legacy drought stress. In this manuscript, we aim to identify seed associated fungi that play critical roles within the wheat seed under drought stress conditions. We examined the endophytic seed fungal communities of three winter wheat cultivars, Catawba, Shirley, and USG 3640. Moderate drought was imposed on a subset of plants immediately after flowering, with plants relieved from drought stress after one week. Seeds harvested from generation 1 were planted for a second generation of drought experiments. When examining post-flowering drought impact on wheat physiology, drought-exposed plants consistently exhibited lower daily transpiration rates, chlorophyll-a values, and seed yield compared to control plants, indicating that drought implementation was successful. ITS1 metabarcoding revealed that wheat seed fungal community species richness decreased during post-anthesis drought stress across both generations. We also observed that generation accounted for variation in fungal species richness and community structure, independent of drought treatment. The most abundant taxa recovered across all cultivars, treatments, and generations included Cladosporium, Penicillium, Alternaria, and Epicoccum. These results support our hypothesis that post-anthesis drought shapes the wheat seed fungal community.","PeriodicalId":48504,"journal":{"name":"Phytobiomes Journal","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140445073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results revealed significant differences in FER severity across environments and varieties, and between inoculation treatments. The lower FER scores of conventional maize Spectrum-6416 relative to other varieties highlight resistant alleles in maize germplasm, while strong correlations indicate FER-induced yield loss. Mitigation of FER by the transgenes was validated by about 3-fold enrichment of Fusarium verticillioides (Fv) post-inoculation, compared to non-significant Fv enrichment in conventional maize. While the major causal pathogen of FER, Fv, was the most abundant species in the metagenomes, similar degree of correlations was observed between FER and several Fusarium spp. (0.2-0.56; Fv: 0.41-0.49). The potential FER-suppressing properties of Talaromyces stipitatus and Ustilago maydis were indicated by negative correlations with FER (-0.22 to -0.42), Fv and some Fusarium spp. The more FER resistant varieties consistently enriched for the potential FER-suppressing Burkholderia cenocepacia (negatively correlated with Fv). This suggests host genetic background-dependent recruitment of beneficial microbes that suppress pathogens and that microbe-microbe interactions play a role in FER severity. Quantitative and species/strain-level metagenomic profiles hold promise for identifying robust disease-suppressing microbes, microbes that act in synergy with pathogens, and for developing a holobiont-aware breeding strategies that accounts for host-microbiome coevolution and host genotype, microbiome/metagenome, and environment (GxGxE) interactions.","PeriodicalId":48504,"journal":{"name":"Phytobiomes Journal","volume":null,"pages":null},"PeriodicalIF":4.4,"publicationDate":"2024-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139592016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
