Stimulating the development of soil suppressiveness against certain pathogens represents a sustainable solution toward reducing pesticide use in agriculture. However, understanding dynamics and mechanisms leading to pathogen control remain largely elusive. Here, we investigated used by rhizosphere microbiome induces bacterial wilt disease suppression long-term field experiment where continuous application bio-organic fertilizers (BFs) triggered when compared chemical fertilizer application. We further demonstrated glasshouse that communities was mainly changes community composition rather than only abundance introduced biocontrol strain. Metagenomics approaches revealed members families Sphingomonadaceae Xanthomonadaceae with ability produce secondary metabolites were enriched BF plant but upon invasion. experimentally validated this observation inoculating isolates belonging into conducive soil, which led significant reduction increase nonribosomal peptide synthetase gene abundance. conclude priming amendment fostered reactive tomato plants response biotic disturbance.

GigaScience, Год журнала: 2022, Номер 11

Deciphering microbiota functions is crucial to predict ecosystem sustainability in response global change. High-throughput sequencing at the individual or community level has revolutionized our understanding of microbial ecology, leading big data era and improving ability link diversity with functions. Recent advances bioinformatics have been key for developing functional prediction tools based on DNA metabarcoding using taxonomic gene information. This cheaper approach every aspect serves as an alternative shotgun sequencing. Although these are increasingly used by ecologists, objective evaluation their modularity, portability, robustness lacking. Here, we reviewed 100 scientific papers inference ecological trait assignment rank advantages, specificities, drawbacks tools, a benchmarking. To date, mainly devoted bacterial functions, fungal A major limitation lack reference genomes-compared human microbiota-especially complex ecosystems such soils. Finally, explore applied research prospects. These promising already provide relevant information functioning, but standardized indicators corresponding repositories still lacking that would enable them be operational diagnosis.
