Predicting the taxonomic and environmental sources of integron gene cassettes using structural and sequence homology of attC sites

“…Among them were the genera Xanthomonas, Lysobacter, Luteimonas, Pseudoxanthomonas, Thermomonas, and Stenotrophomonas (Supplementary Table 3). Most of these genera are commonly found associated with plant leaves and roots [30][31][32][33] , suggesting that the Xanthomonadales-like attC clade might represent plant-associated environments. If this is the case, then plant-associated bacteria might be a significant source of a large proportion of resistance gene cassettes.…”

Enabling sustainable agriculture through understanding and enhancement of microbiomes

“…The application of native microbiota that are well adapted to the environmental conditions, soil types and/or plant niche (e.g. rhizosphere or phyllosphere) provide a greater chance of establishment and manifestation of beneficial traits compared to alien microbiota (Gu et al ., 2020). Through an experimental evolutionary approach, it is possible to select for a robust, plant‐optimized microbiome that is resistant to random invasion (Morella et al ., 2020).…”

Mycorrhizal symbiosis balances rootstock-mediated growth-defence tradeoffs

“…Looking at the whole microbial community, in addition to a selection based on the rootstock genotype, it is worth noting that I treatment (particularly I SO4) was able to significantly increase diversity of the microbiota (Table S4). Samples treated with the inducer showed higher bacterial diversity hosting many groups of PGPBs such as Burkholderiaceae that might be linked to potassium (K) and phosphorous (P) solubilization and availability (Gu et al 2020); Pseudomonas and Bacillus spp. able to produce siderophores, auxin, cytokinins and characterized as phosphate-solubilizing bacteria (Saad et al 2020;Subrahmanyam et al 2020) (Table S7).…”
