Summary: The diversity of cropping systems affects the composition of soil microbial communities, particularly in the rhizosphere and endosphere. Diversified cropping systems recruit a more diverse bacterial community in the rhizosphere, while fungal species richness varies between different cropping systems.

Summary: The taxonomic composition and functions of the plant bacterial community are influenced by soil and host plant genotype. Plant breeding has indirectly modified the ability of plant roots to recruit an effective bacterial community. A study on the interactions between plant genotype and microbiome showed that plant variety had the most significant impact on the rhizosphere bacterial community, while fertilization treatments did not affect either bacterial community diversity or abundance.

Summary: This study investigated the structure and diversity of bacterial communities in the rhizosphere of 35 barley varieties using high-throughput sequencing technology. The results showed that there were minor differences in bacterial abundance among varieties, but the abundance of the same bacteria varied in rhizospheres of different varieties. In addition, clustering and principal component analyses divided the samples into three groups at the phylum level.

Summary: In this study, 16S rRNA gene amplicon sequencing was used to investigate the impact of rice bacterial leaf blight (BLB) on the rice rhizosphere microbial community. The results showed that the alpha diversity index of the microbial community decreased significantly during the onset of BLB and gradually recovered to normal levels. Beta diversity analysis indicated that BLB had a significant effect on community composition. Furthermore, there were significant differences in the taxonomic composition between healthy and diseased groups, with certain genera being more abundant in diseased rhizospheres such as Streptomyces, Sphingomonas, and Flavobacterium. Additionally, the size and complexity of the rhizosphere co-occurrence network increased after disease onset, and hub microbes like Rhizobiaceae and Gemmatimonadaceae played important roles in maintaining network stability. Overall, this study provides important insights into the response of the rhizosphere microbial community to BLB and offers valuable data and ideas for using rhizosphere microbes to control BLB.

Summary: The repeated application of fungicide may have detrimental effects on the rhizosphere bacterial community of citrus. However, the usage of mancozeb did not significantly impact the chemical properties and richness and diversity of rhizosphere bacterial community in citrus-cultivated soil.

Summary: This study investigates the effects of grass-legume mixtures and monocultures on forage production and rhizosphere bacterial communities. The results show that grass-legume mixtures significantly increase forage production and alter the structure and composition of the grass rhizosphere bacterial community. The legume plays a significant role in influencing the grass rhizosphere. Additionally, the grass-legume mixtures provide favorable conditions for microbial interactions.

Summary: A Bacillus strain, identified as Bacillus aryabhattai strain LAD, was isolated from long-term maize colonization soil. The study showed that LAD had phosphate-solubilizing and nitrogen-fixing functions that benefited plant growth. The treatment with LAD culture significantly influenced the root system development of corn seedlings and the structure of rhizosphere bacterial communities.

Summary: This study investigated the differences in bacterial communities between seagrasses and bulk sediments in Chilika, a brackish water coastal lagoon of India. The results showed that seagrasses had an effect on the diversity, composition, and abundances of benthic bacterial communities. Seagrasses supported higher bacterial abundances compared to bulk sediments, and the interactions and connectedness among seagrass bacterial communities were stronger. Seagrasses and environmental factors were the major drivers of benthic bacterial community composition. Heterotrophic bacteria in seagrass sediments showed higher metabolic diversity and activity than in bulk sediments, and seagrass sediments enhanced the utilization of carbon substrate guilds. Seagrasses play crucial roles in the organic matter cycling and degradation of hydrocarbon and xenobiotics in coastal sediments.

Summary: The study investigated the response of sugarcane rhizosphere bacterial community to drought stress, finding that the bacterial community structure remains stable and correlates with the drought adaptability of sugarcane. Changes in abundance of rhizosphere bacteria under drought stress are mainly influenced by soil conditions and the physiological state of the host plant.

Summary: Root section identity was found to be the most influencing factor on the microbiota composition, with a clear tradeoff between reproducibility and sensitivity of the two sampling strategies (root section sampling and homogenized sampling), highlighting the importance of complementing traditional approaches with fine-scale sampling for a better understanding of biological effects.

Summary: The introduction of microbial inoculants into the soil can affect the succession process of native soil communities, especially in highly diverse communities. Even if the invader is not successful, the resident bacterial communities exhibit patterns of secondary succession.

Summary: The study found that introducing a symbiotic bacterial consortium SPMX comprising four bacterial species can significantly enhance drought tolerance in Arabidopsis plants. Additionally, the addition of SPMX helps stabilize the diversity and structure of root-associated microbiomes, contributing to overall plant health under drought stress. These SPMX-induced changes collectively result in increased drought tolerance in plants, highlighting the potential for engineering emergent bacterial community properties to improve plant resilience to drought.

Summary: Rhizosphere-enriched microbes induced by foliar phytopathogen infection can assemble into a functional community to enhance plant defense mechanisms. In this study, the changes in rhizosphere bacterial communities in tomato plants infected with Botrytis cinerea were investigated. Specific rhizosphere bacterial taxa were recruited by the phytopathogen-infected plants, while several bacterial taxa stably colonized the rhizosphere regardless of phytopathogen infection. A synthetic community consisting of 8 phytopathogen-inducible and 30 stably-colonizing bacteria species were established through the analysis of the rhizosphere bacterial community.
