Several and strains from the north of Mexico were isolated during the description of strains. , and were later described as novel species. Next, the Genomic Encyclopedia of Bacteria and Archaea project retrieved the genome sequences of several strains from the above species. Standard comparative genomic analysis showed that MLR2-44 was taxonomically misclassified. This strain, isolated from the rhizosphere, was analysed by average nucleotide identity (ANI), revealing that was the closest species (95.6%). However, the digital DNA-DNA hybridization (dDDH) resulted in values lower than 68% for any type strain of species. Moreover, it was also found that LMG 19430, isolated from root nodules, was closer to strain MLR2-44 (99.9% ANI and 99.8% dDDH), instead of being associated with the type strain of LMG 19424 (94.4% ANI and 54.6% dDDH), thus making strains MLR2-44 and LMG 19430 a single genomic species. Accordingly, the polyphasic analysis showed that these strains represent a new species; therefore, we propose that strains MLR2-44 (=CDBB B-2066=TSD-312) and LMG 19430 encompass a novel species with the name of sp. nov.

Plant growth-promoting rhizobacteria (PGPR) are widely recognized for enhancing the absorption of mineral nutrients by crops. While Sphingobium species have been reported as PGPRs, their capacity to improve nitrogen use efficiency (NUE) and the underlying regulatory mechanisms are not yet fully understood. Here, a strain 41R9, isolated from the rhizosphere of N-deficient rapeseed, was found to significantly enhance the growth performance of rapeseed under both low and normal N conditions.

Mahonia eurybracteata exhibits characteristics related to heat dissipation, nutritional supplementation, and possesses antimicrobial and anticancer properties. Despite its widespread cultivation through artificial means, the detrimental impact of anthracnose on its growth has led to extensive reliance on chemical pesticides for disease control. Unscientific pesticide application and the use of outdated spraying techniques contribute to the presence of pesticide residues in both plants and the environment, thereby posing potential risks.

The application of pesticides may have significant impacts on soil environment and communities. In order to understand the deep relationship between the application of chlormequat chloride (CC) and the bacterial community in peanut soil, high-resolution characterization was performed using peanut soil samples (12 points; 0-20 cm rhizosphere soil) from untreated and sprayed with different concentrations of CC. Experimental data showed that with the increase of concentration, operational taxonomic units (OTUs) richness showed a decreasing tendency.

To investigate the changes in rhizosphere soil microbial communities of different dominant plants after years of restoration, this study examines the improvement effects of different dominant plants on the soil environment.
Results: This study is based on high-throughput sequencing to restore the slope of coal mine spoil after 15 years as the sampling site.
