Summary: The Pseudomonas strain T1-3-2(T) isolated from Cunninghamia laceolata exhibits growth-promoting and antifungal activities. Through polyphasic taxonomy and genome sequencing analysis, it was found that strain T1-3-2(T) shows high similarity with Pseudomonas eucalypticola but is distinct from any known Pseudomonas species. Genomic analysis revealed the presence of three circular DNA contigs in strain T1-3-2(T), including a chromosome and two plasmids. This strain has the potential to promote plant growth and control diseases, with encoded genes related to antibiotic and secondary metabolite production, siderophore uptake and biosynthesis, and pyoverdine biosynthesis.

Summary: Agroforestry systems and legume sowing are considered efficient in terms of soil function, with legume-enriched pastures showing higher microbial biomass, diversity, and activity compared to control pastures. There was an increase in soil carbon stocks after sowing, which was related to legume abundance, phosphorous fertilization, and forage yield. The shift in microbial community structure and the positive legacy of increased soil carbon stocks and nutrient fixation by legumes can help enhance pasture productivity and climate-resilience, but further research is needed.

Summary: Canola is the third most common oil-producing crop worldwide, cultivation requires chemical fertilizers but the use can be reduced with plant growth-promoting bacteria; identified endophytic bacteria isolates from canola roots, including Bacillus, Neobacillus, Paenibacillus, Pseudomonas, and Peribacillus genera, some of which efficiently promote canola seedling growth; Paenibacillus and Peribacillus isolates were the most promising biofertilizers for canola crops, particularly due to their sporulated rods trait.

Summary: This study compares tree populations forming the distribution limits of mountain pine in northeastern Spain. The results show that tree growth is influenced by climate and soil properties. There are marked differences in leaf traits and growth response to climate between treeline and rearedge sites. The soil microbiota in treelines is dominated by bacteria, while in forests it is dominated by fungi.

Summary: Two rod-shaped Gram negative strains, SSUT16T and SSUT22, were isolated from root nodules of Spartocytisus supranubius in soils of the Teide National Park (Tenerife, Spain). The 16S rRNA gene sequences classified them as a novel species within the genus Bosea, and the MLSA analysis and genome sequence analysis further confirmed their distinctiveness. Based on phylogenetic, genomic, chemotaxonomic, and phenotypic characterization, a new species named Bosea spartocytisi sp. nov. is proposed.

Summary: Intensive livestock management can cause nitrogen pollution in water bodies, but the impact of manure application on agroforestry systems is not well understood. This study assessed how pig manure affects tree growth and the nitrogen cycle in two commonly planted tree species. The results showed that fertilized trees had higher soil nutrient concentrations but lower soil microbial biomass. Pine trees showed similar growth between fertilized and non-fertilized trees, while almond trees showed lower growth when fertilized. Leaf nitrogen concentrations decreased, but wood nitrogen isotopes increased in trees subjected to pig manure application. This suggests that pig manure alters nitrogen cycling in both soil and trees.

Summary: Strain CRRU44(T) was isolated from the stems of Rubus ulmifolius plants growing in Salamanca, Spain. Phylogenetic and phylogenomic analyses revealed that strain CRRU44(T) represents a novel species and genus within the family Rhizobiaceae, distinct from other genera in the family. The name Ferranicluibacter rubi gen. nov., sp. nov. is proposed for this new genus and species, with strain CRRU44(T) designated as the type strain.

Summary: Natural grasslands in South America are important for livestock grazing, and legume overseeding and P fertilization are commonly used to enhance productivity. However, the effects of this management on soil microbial communities are unclear. This study analyzed the impact of Lotus subbiflorus overseeding and P fertilization on soil microbial community diversity and activity in the Uruguayan Pampa region. The results showed that plant communities differed between natural grassland paddocks and managed paddocks, but microbial biomass, respiration, and diversity were not significantly affected. However, the structure of bacterial and fungal communities were correlated with plant communities, and AM Fungi abundance and enzyme activities were significantly affected.
