Transformative advances in metagenomics are providing an unprecedented ability to characterize the enormous diversity of microorganisms and invertebrates sustaining soil health and water quality. These advances are enabling a better recognition of the ecological linkages between soil and water, and the biodiversity exchanges between these two reservoirs. They are also providing new perspectives for understanding microorganisms and invertebrates as part of interacting communities (i.e. microbiomes and zoobiomes), and considering plants, animals, and humans as holobionts comprised of their own cells as well as diverse microorganisms and invertebrates often acquired from soil and water. The Government of Canada's Genomics Research and Development Initiative (GRDI) launched the Ecobiomics Project to coordinate metagenomics capacity building across federal departments, and to apply metagenomics to better characterize microbial and invertebrate biodiversity for advancing environmental assessment, monitoring, and remediation activities. The Project has adopted standard methods for soil, water, and invertebrate sampling, collection and provenance of metadata, and nucleic acid extraction. High-throughput sequencing is located at a centralized sequencing facility. A centralized Bioinformatics Platform was established to enable a novel government-wide approach to harmonize metagenomics data collection, storage and bioinformatics analyses. Sixteen research projects were initiated under Soil Microbiome, Aquatic Microbiome, and Invertebrate Zoobiome Themes. Genomic observatories were established at long-term environmental monitoring sites for providing more comprehensive biodiversity reference points to assess environmental change.

Plant roots are colonised by diverse communities of microorganisms that can affect plant growth and enhance plant resistance to (a) biotic stresses. We investigated the role of the indigenous soil microbiome in the resistance of tomato to the invasive sap-sucking insect Prodiplosis longifila (Diptera: Cecidomyiidae). Native and agricultural soils were sampled from the Andes in Southern Ecuador and tested, in greenhouse bioassays, for leaf tissue damage caused by P.

Biofilms are a primary form of device-associated infections and typically exhibit high tolerance to antimicrobial agents. In biofilms formed by multiple microbial species, microorganisms may show even greater tolerance, complicating treatment. There is evidence that meropenem (MEPM) tolerance in is increased in dual-species biofilms with , and effective treatments have not been established.

The Toll signaling pathway serves as a crucial regulatory mechanism in the insect innate immune system, playing a pivotal role in defending against pathogenic microorganisms. However, the specific functions of aphids' unique immune system and Toll signaling pathway remain poorly understood. In this study, we systematically analyzed 12 key genes associated with the Toll signaling pathway in Myzus persicae.

Microbial consortia, involving two or more microorganisms, have been explored for pest management purposes, despite concerns regarding competitive exclusion among entomopathogenic fungi that may undermine synergistic effects. However, the precise molecular mechanisms governing entomopathogen competition in vivo remain inadequately elucidated. Here, we investigate competitive exclusion dynamics between two prominent entomopathogens, Metarhizium robertsii and Beauveria bassiana.

Fomesafen (FSA), a diphenyl ether herbicide, causes toxicity to non-target organisms and subsequent crops. Vermi-remediation is advocated as an effective remediation method, but there has been no research on the isolation and mechanism of FSA-degradation strains from earthworm gut. In this study, three ecotypes of earthworms- Eisenia foetida (epigeic), Metaphire guillelmi (anecic), and Aporrectodea caliginosa (endogenic), were used to investigate the degradation mechanism of FSA in soil-plant-earthworm systems for the first time.
