Summary: A novel species of Streptomyces, named Streptomyces coriariae sp. nov., was isolated from the root nodules of a Coriaria intermedia plant along Halsema Highway in Luzon, Philippines. The strain CMB-FB showed high sequence similarity to several known Streptomyces species based on 16S rRNA gene sequence analysis. The isolate also displayed characteristic features such as major menaquinones, polar lipid profile, diagnostic diamino acid of the peptidoglycan, and major fatty acids.

Summary: This study identified a symbiotic relationship between nodulated legume and strains of genus Rhizobium in Croatia. The analysis revealed that these strains are closely related to species from the Rhizobium leguminosarum phylogenetic complex. Based on genetic and phenotypic analyses, two novel species within the genus Rhizobium were proposed and named Rhizobium croatiense and Rhizobium redzepovicii.

Summary: The study used a genealogical concordance approach to classify strains isolated from Acacia dealbata and Acacia mearnsii root nodules in South Africa. These isolates belong to the Bradyrhizobium genus based on 16S rRNA sequence similarity. Phylogenetic analysis of six housekeeping genes confirmed that these isolates represent a new species, while ANIb calculations with the closest type strains showed values below 95-96%. Phenotypic tests revealed high levels of intraspecies variation, and analysis of nodA and nifD loci indicated a close relationship with Bradyrhizobium isolates from Australia. The type strain of the novel species proposed as Bradyrhizobium xenonodulans sp. nov. is 14ABT (=LMG 31415 T = SARCC-753 T).

Summary: In this study, a Gram-positive aerobic, endospore-forming bacterium isolated from the rhizosphere of maize was taxonomically characterized as a novel species of the genus Sutcliffiella, named Sutcliffiella rhizosphaerae sp. nov., based on phylogenetic analysis and DNA-DNA hybridization. The strain showed high similarity with Sutcliffiella zhanjiangensis (98.7%) and distinct differences from other closely related species of the genus Sutcliffiella.

Summary: Two endophytic strains, MOVP5T and MOPV6, isolated from nodules of Phaseolus vulgaris plants in Southeastern Spain, represent a potential new species of Agrobacterium based on genetic and phenotypic analysis. The strains show distinct differences from all known genomovars of Agrobacterium, supporting their classification as a novel species Agrobacterium leguminum sp. nov.

Summary: Eight Gram-negative, aerobic, motile with paired polar flagella and rod-shaped bacteria from tobacco fields in Yunnan, PR China were identified as Ralstonia genus. The strains showed high similarity to R. wenshanensis, R. pickettii, and R. insidiosa. Genome sequencing revealed the presence of new species within the genus Ralstonia. Based on the data, three new species names were proposed.

Summary: Three plant rhizogenic strains O132T, O115 and O34 isolated from Cucumis sp. L. are classified as a novel species, Agrobacterium cucumeris, based on their genetic sequences, DNA-DNA hybridization, and physiological characteristics compared with their closest relatives in the genus Agrobacterium. These strains belong to the separate sub-clade biovar 1 within the genus Agrobacterium.
