“…Furthermore, viruses can encode other AMGs that enhance the metabolism of corrosive microbes. In Rc, AMG cysH, which is involved in sulfur metabolism and has been extensively discovered in other environments, was identified [48, 49]. In our study, we identified AMGs potentially associated with the MIC.…”

In marine environments, a wide variety of microbes exert an important influence on the corrosion of materials. Viruses are widely distributed in biofilms formed on materials and may influence the corrosion process through interactions with key corrosive microbes. However, our understanding of the viral communities within biofilms and their implications for corrosion remains notably limited. To fill this knowledge gap, we utilized 53 publicly metagenomes to investigate the ecological dynamics of viruses within biofilms on 8 different materials and their potential roles in the corrosion of materials. In biofilms, the type of materials may be the primary factor driving differences in the diversity of viral communities. Viruses within biofilms predominantly belong toCaudoviricetes,and phylogenetic analysis ofCaudoviricetesand protein-sharing networks with other environments revealed the presence of numerous novel viral clades in biofilms. The presence of virus‒host linkages revealed a close association between viruses and corrosive microbes in biofilms. Viruses play a key role in corrosion by modulating host corrosion-related metabolism. It was observed that viruses could enhance host resistance to metals and antibiotics via horizontal gene transfer. Furthermore, viruses can protect themselves from host antiviral systems through anti-defense systems. Overall, this work illustrates the diversity of viruses within biofilms formed on materials and the intricate interactions between viruses and corrosive microbes, revealing the potential roles of viruses in microbially influenced corrosion.

“…Viruses can contribute to the genetic and phenotypic evolution of their hosts, raising their competitiveness and environmental adaptability through AMGs ( 30 ). In carbon-poor soils, viruses established an enhanced beneficial relationship with bacteria, reflected by the elevated total abundance of AMGs annotated as CAZyme genes ( Fig.…”

Organic carbon availability in soil is crucial for shaping microbial communities, yet, uncertainties persist concerning microbial adaptations to carbon levels and the ensuing ecological and evolutionary consequences. We investigated organic carbon metabolism, antibiotic resistance, and virus–host interactions in soils subjected to 40 y of chemical and organic fertilization that led to contrasting carbon availability: carbon-poor and carbon-rich soils, respectively. Carbon-poor soils drove the enrichment of putative genes involved in organic matter decomposition and exhibited specialization in utilizing complex organic compounds, reflecting scramble competition. This specialization confers a competitive advantage of microbial communities in carbon-poor soils but reduces their buffering capacity in terms of organic carbon metabolisms, making them more vulnerable to environmental fluctuations. Additionally, in carbon-poor soils, viral auxiliary metabolic genes linked to organic carbon metabolism increased host competitiveness and environmental adaptability through a strategy akin to “piggyback the winner.” Furthermore, putative antibiotic resistance genes, particularly in low-abundance drug categories, were enriched in carbon-poor soils as an evolutionary consequence of chemical warfare (i.e., interference competition). This raises concerns about the potential dissemination of antibiotic resistance from conventional agriculture that relies on chemical-only fertilization. Consequently, carbon starvation resulting from long-term chemical-only fertilization increases microbial adaptations to competition, underscoring the importance of implementing sustainable agricultural practices to mitigate the emergence and spread of antimicrobial resistance and to increase soil carbon storage.

“…Microbiome-based control concepts are an interesting alternative to current pesticides, fertilizers and disinfectants (Vandini et al 2014 ). Plant and environmental health are directly linked to human health which becomes clear from the unintended consequences of intense agriculture in the former Aral Sea region (Wicaksono et al 2023b ) and destructive mining practices in the Salares of the hyperarid Atacama Desert in Northern Chile (Bonelli and Dorador 2021 ). Another link between human health and the depleted plant microbiome, especially the “edible microbiome”, was already suggested in 2015, which needs further evaluation (Berg et al 2015 , Wicaksono et al 2023a ).…”

The Holobiont theory is more than eighty years old, while the importance of microbial communities for plant holobionts was already identified by Lorenz Hiltner more than a century ago. Both concepts are strongly supported by results from the new field of microbiome research. Here, we present ecological and genetic features of the plant holobiont that underpin principles of a shared governance between hosts and microbes and summarize the relevance of plant holobionts in the context of global change. Moreover, we uncover knowledge gaps that arise when integrating plant holobionts in the broader perspective of the holobiome as well as one and planetary health concepts. Action is needed to consider interacting holobionts at the holobiome scale, for prediction and control of microbiome function to improve human and environmental health outcomes.
