“…This finding to some extent disapproved our hypothesis that microbial community compositions in soils should be associated with plant species. It has been well documented that in terrestrial soils plant species affect rhizosphere microbial communities 4 , 6 , 25 – 28 . Conversely, based on the plant-soil feedback theory, soil microbes can significantly affect plant communities by altering soil physicochemical and trophic properties or regulating plant coexistence 29 – 32 .…”

Bacterial communities play an important role in mangrove ecosystems. In order to gain information on the bacterial communities in mangrove species and rhizospheres grown in Zhangjiangkou National Mangrove Nature Reserve, this study collected root, branch, and leaf samples from five mangrove species as well as rhizosphere and non-rhizosphere samples and analyzed the community structure of endophytic bacteria and bacteria in rhizosphere and non-rhizosphere using Illumina high-throughput sequencing technique. Bacteria in 52 phyla, 64 classes, 152 orders, 295 families, and 794 genera were identified, which mainly belonged to Proteobacteria, Cyanobacteria, Actinobacteria, Firmicutes, Bacteroidetes, Fusobacteria, and Nitrospirota. At each taxonomic level, the community structure of the rhizosphere bacteria varied slightly with mangrove species, but endophytic bacteria differed greatly with plant species. The diversity indices of endophytic bacteria in branch and leaf samples of Acanthus ilicifolius were significantly lower, and endophytic bacteria in the plant tissues had higher abundance in the replication/repair and translation Clusters of Orthologous Genes functional categories but lower abundance in the carbohydrate metabolism category. This study helps to understand the community structure and diversity characteristics of endophytic and rhizosphere bacteria in different mangrove plants. Provide a theoretical basis for in-depth research on the functions of mangrove ecosystems.

“…N is closely linked to soil nutrient flows and turnover (Isobe et al, 2020). When the N source in the soil ecosystem is limited, microbes decompose carbon (C) sources such as litter to access resources and sustain soil nutrient balance (Ding et al, 2021; Fu et al, 2022). In forest ecosystems, the decomposition of litter is a significant process that replenishes soil N (Wang, Chen, et al, 2020; Wang, Song, et al, 2022).…”

Nitrogen (N) metabolism is a key metabolic pathway of nutrient cycling in forest ecosystems. However, the mechanisms by which mixed plantation forest litter improves microbial N transformation are poorly understood. Thus, we investigated the N characteristics, N metabolism‐related genes, and key microbial modules of litter and soil in three types of forests: coniferous (CP forest), broadleaf (BP forest), and mixed forests (MCBP forest). Results indicated that the total N (TN), total hydrolysable organic N (THON), and percentage values of NH4+‐N/TN and NO3−‐N/TN in BP forest and MCBP forest litter were higher than those of CP forest litter, which was attributed to the increase in abundance of N fixation genes and dissimilatory nitrate reduction genes. The MCBP forest increased the bacterial number and diversity, and the abundance of key bacterial taxa. Bacterial key modules 1 and 2 were identified, consisting of Acidobacteria, Actinobacteria, Chloroflexi, Nitrospirae, Proteobacteria, and Gemmatimonadetes, while archaeal module 5 was also a key module, comprising Thaumarchaeota and Euryarchaeota. Nutrients were the limiting factor of key microbial modules in the decomposition of litter, further influencing N metabolism‐related genes and enzymes. Therefore, mixed plantation forests increased microbial N fixation and transformation during litter decomposition in northern China.

“…The total abundance of active soil microorganisms is directly correlated with the amount of organic matter, so it is important to quantify them to determine their significance for soil quality [9,10]. The quantity of these microorganisms shows marked seasonal changes, as well as differences in taxonomic structure depending on the ecosystem type [11][12][13].…”

In this study, we aimed to compare the functional and taxonomic composition of soil microbial communities in different ecosystems, agricultural, natural grasslands, and old-growth forests, in the context of different environmental conditions. In this research, cultivable microbial quantification was performed by conventional plate-count techniques using different selective media. The taxonomic structure of microbe communities was evaluated using NGS metagenomic sequencing on the Illumina platform NovaSeq. The taxonomic analysis showed that individual land uses are characterized by the specific structure of communities; some taxonomic groups are specific only to agricultural, grassland, or forest ecosystems. After determining the abundance of functional groups of culturable microorganisms by the conventional plate-count method, statistically significant quantitative differences in physiological groups between the individual ecosystems were revealed. The metagenomic analysis revealed that different ecosystems are characterized by specific taxonomic groups of microorganisms and that general alpha diversity varies among individual land-use samples. Since the most unstable soil systems are agricultural, they are likely to suffer the most and will suffer more in the future from climate change than natural ones.
