Two strains isolated from soil samples were designated as YH-JAE5 and YH-JAE2. The isolates were facultative anaerobic, Gram-stain-variable, motile, rod-shaped bacteria. Phylogenetic analysis indicated that the isolates belonged to the genus , but the 16S rRNA gene sequence similarities were <98 % when compared with other species within the genus. Analysis of gene revealed the isolates formed a sub-cluster with . The only menaquinone identified was MK-7. The two isolates contained -diaminopimelic acid within their cell wall peptidoglycan. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phospholipid, aminophospholipids, and lipids. The major fatty acids were C anteiso and C iso. The average nucleotide identity, average amino acid identity, and digital DNA-DNA hybridization values between isolate YH-JAE5 and the most closely related reference strain ( KCTC 3758) were 81.7, 84.8 and 23.4 %, respectively. The G+C content of the genomic DNA was 47.4 mol%. Thus, the polyphasic data revealed that YH-JAE2 (=KCTC 43239=JCM 34435) and YH-JAE5 (=KCTC 43059=JCM 33533) represent a new species. The name sp. nov. is proposed.

Aggressiveness and phylogenetic relationship of associated with crown and root rot in pyrethrum plants.

Plant Dis

In Australia, pyrethrum (Tanacetum cinerariifolium) cultivation provides a significant portion of the global supply of natural insecticidal pyrethrins. However, crown and root rots, along with stunted plant growth and plant loss during winter, are significant issues affecting certain sites. Several isolates of the Fusarium oxysporum species complex (FOSC) have been identified as causal agents of crown and root rot in pyrethrum, highlighting these as key pathogens contributing to this decline.

An obligately anaerobic, spore-forming sulphate-reducing bacterium, strain SB140, was isolated from a long-term continuous enrichment culture that was inoculated with peat soil from an acidic fen. Cells were immotile, slightly curved rods that stained Gram-negative. The optimum temperature for growth was 28 °C.

Introduction: Exploring the interactions between dark septate endophytes (DSE) in plant roots across diverse heavy metal habitats-considering host plants, site characteristics, and microbial communities-provides insights into the distribution patterns of DSE in metal-rich environments and their mechanisms for developing heavy metal resistance.

Methods: This study collected samples of three common plant species (, PA, , SV, and , AA) and their corresponding soil samples from three heavy metal-contaminated sites: Baiyang Lake, BY, Fengfeng mining area, FF, and Huangdao, HD. Utilizing high-throughput sequencing and physicochemical analysis methods, the biological and abiotic factors affecting DSE colonization and distribution in the roots were investigated.

Carbon monoxide (CO) oxidising microorganisms are present in volcanic deposits throughout succession, with levels of vegetation and soil influencing the communities present. Carboxydovores are a subset of CO oxidisers that use CO as an energy source, which raises questions about the physiological and metabolic features that make them more competitive in harsh volcanic ecosystems. To address these questions, samples were taken from volcanic strata formed by eruptions from Calbuco Volcano (Chile) in 2015 (tephra) and 1917 (soil).
