Summary: This study explored the interaction between plant genetics and microbiomes using 100 tea plant cultivars. The results showed that diverse host factors play a role in driving microbial variation in plant-associated environments. The genetic mechanisms behind this phenomenon were found to be compartment-specific, with certain genes associated with specific microbial compositions in different plant compartments.

Summary: Soil microbiota plays a significant role in the development and health of plants, including grapevines. This study examined the impact of soil microbiological quality and grapevine rootstock genotype on the development of root microbial community in young grapevine plants. The results showed that the soil status and rootstock genotype influenced the colonization of mycorrhizal fungi and the number of microorganisms in the rhizosphere. Fungal diversity and richness were affected by both the soil status and rootstock genotype, while bacterial richness was only influenced by the genotype. Fungal genera associated with grapevine diseases were more abundant in declining soils. The study also found that rootstock genotype influenced the compartmentalization of microbial communities.

Summary: Root-rot disease has caused serious damage to Zanthoxylum bungeanum trees and led to a reduction in yields. The disease affected soil physicochemical properties and microbial communities, as well as microbial diversity and composition in the root endosphere. The imbalance of root and soil microbial function groups may have contributed to the occurrence of the disease.

Summary: The research reveals significant differences in root microbiomes between historically arid and humid sites, with aridity and soil pH levels being the main factors explaining these differences. Additionally, roots under arid conditions show unique associations with specific bacterial genera.

Summary: The root microbiome consists of distinct epiphytic and endophytic habitats, with differences in abiotic and biotic factors driving diversity and composition differences between these habitats. Our study found significant differences in bacterial community between the rhizosphere and endosphere, with higher connectivity observed among core bacterial members in the endosphere. Taxonomic assortativity was higher in the endosphere, with positive co-occurrence more likely among bacteria within the same phylum and negative co-occurrence more likely between bacterial taxa from different phyla. Drought had limited effects on network properties but increased the proportion of shared co-occurrences between rhizosphere and endosphere networks.

Summary: In this study, a comprehensive method called Qscore was proposed to evaluate the performance of 16S rRNA amplicons in microbial profiling. The method integrated factors such as amplification rate, taxonomic annotation, sequence type, and length. Evaluation of a wide range of microbe species and microbiomes showed that the Qscore-suggested parameters resulted in high precision in microbiome profiling. This study has significant implications for guiding future microbiome studies and enabling the reuse of massive sequence data.

Summary: In this study, the diversity and composition of bacterial endophytes in cherry laurel leaves were analyzed using Illumina-based 16S rRNA gene metabarcoding. The results showed that the endophytic bacterial community structure changed during the seasonal transition from winter dormancy to a spring vegetative state. The richness and diversity of the community increased significantly in May compared to other months, and the variation in community structure was mainly associated with less abundant community members.

Summary: Intensive agricultural systems have positive effects on supporting the growing human population, but the excessive use of mineral fertilizers and pesticides may have negative impacts on nutrient cycles and biodiversity. Harnessing the beneficial relationships between plants and plant-associated rhizobacteria can increase nutrient-use efficiency and provide pathogen resistance. Analyzing the plant-associated microbiota using high-throughput sequencing can lead to improved taxonomic classification and identification of new plant-associated microbes.

Summary: The study evaluated the microbial diversity of the rhizosphere and root endosphere of desert halophytes in arid environments of Pakistan, finding that Proteobacteria were more abundant in rhizospheric soils, while Actinobacteria were dominant in the root endosphere of halophytes. Bacillus, Kocuria, Pseudomonas, Halomonas, and Flavobacterium were commonly identified from the rhizosphere and root endosphere of halophytes across all three sites. This study highlights the potential for microbial diversity analysis to study the impact of abiotic factors on microbial communities associated with halophyte roots in arid regions.

Summary: In this study, the healthy and diseased rhizosphere microbiome of two upland cotton cultivars were evaluated to understand the interactions between microbiome assembly and plant health in relation to Verticillium wilt. The results showed differences in the composition and abundance of microbiome members between the healthy and diseased rhizospheres, as well as between the resistant and susceptible cultivars. Understanding these interactions can contribute to the control and management of Verticillium wilt in cotton production.

Summary: The rhizospheric bacterial community was unique for each sampling site, yet endosphere communities were similar between Antarctic and Central European specimens. Key plant-associated bacterial taxa such as Rhizobiaceae were poorly represented in Antarctic samples, possibly due to high salinity and heavy metal concentrations in the soil. Metabolic activity in Antarctic specimens was considerably lower than in Central European samples.

Summary: This study explores the rhizosphere and endosphere bacterial communities of the common bean plant throughout its growth stages, and finds that the rhizosphere communities are more diverse than the endosphere communities. The composition and abundance of microbial taxa vary at different stages of plant growth.

Summary: This study evaluated temporal shifts in root endophytic prokaryotic communities associated with carrots and the effect of organic matter application on them. The results showed that the rhizosphere prokaryotic community compositions were stable, while the endosphere prokaryotic communities were more affected by time and organic matter application. Different treatments resulted in significant differences in the abundance and diversity of the endosphere prokaryotic community. Genera such as Burkholderia, Sphingomonas, and Rhodanobacter, which have plant-growth-promoting and biocontrol activities, were detected regardless of the treatments.
