“…According to research found that most microbial community have little difference at phylum level, which is basically consistent with the results of this study, which fully demonstrated the similarity of microbes in larger taxonomic units (Rim et al, 2021;Sun et al, 2021). At present, endophytes can be isolated from various parts and organs of studied plants, such as root, stem, leaf, fruit, and seed, and the structure composition and abundance of endophytes will change with different plant varieties, parts, and development periods (Dong et al, 2018;Lv et al, 2021). This study reveals that there are signi cant differences between the microbial communities screened from rhizosphere soil and endophytic communities screened from different parts of S. sphenanthera (Table S3 and S4).…”

Background and aims: Endophyte and rhizosphere soil microorganism are vital microbial environments of the plant, namely plant microenvironments. A robust understanding of the structural composition of the microbiome present in below-ground and above-ground communities has remained elusive. Schisandra sphenanthera Rehd. et Wils. is a kind of traditional Chinese Medicine (TCM) of Schisandra, which can protect the kidney and liver. Methods: In this study, high-throughput sequencing analysis is applied to unravel microbial communities in rhizosphere soil and different parts of wild S. sphenanthera, and the movement regularity of endophytes in plant tissues.Results: There are differences in microbial composition and diversity between rhizosphere soil and four parts of S. sphenanthera. Proteobacteria, Cyanobacteria, and Acidobacteria are main bacteria, Ascomycota and Basidiomycota are main fungi at phylum level of microbe in S. sphenanthera. There are 12 common bacterial genera and 11 common fungal genera in rhizosphere soil and different parts of S. sphenanthera. In addition, each of the four parts and rhizosphere soil have its own dominant communities, such as Achromobacter (stem and leaf) and Methylobacterium (leaf). OTUs clustering results indicate that the bacterial community of root is greatly influenced by rhizosphere soil, while the microbial community of stem and fruit are greatly affected by the microorganisms of leaf. Conclusions: Understanding the microbial community structure and diversity in rhizosphere soil and different parts of S. sphenanthera can provide basis for further study of host-microbial interactions of S. sphenanthera in phytoremediation, sustainable utilization, and secondary metabolite production.

“…Within this bacterial diversity, there are many candidates that can positively influence plant development. This is the case with Sphingomonas sp., which are usually identified in taxonomic inventory approaches using metabarcoding with abundance that can reach 40% of the total bacterial abundance [ 39 , 40 , 41 , 42 ]. As previously reported, S. sediminicola was found to be highly abundant in agricultural soils after pea culture [ 41 ].…”

Current agricultural practices rely heavily on synthetic fertilizers, which not only consume a lot of energy but also disrupt the ecological balance. The overuse of synthetic fertilizers has led to soil degradation. In a more sustainable approach, alternative methods based on biological interactions, such as plant growth-promoting bacteria (PGPRs), are being explored. PGPRs, which include both symbiotic and free-living bacteria, form mutualistic relationships with plants by enhancing nutrient availability, producing growth regulators, and regulating stress responses. This study investigated the potential of Sphingomonas sediminicola Dae20, an α-Proteobacteria species commonly found in the rhizosphere, as a beneficial PGPR. We observed that S. sediminicola Dae20 stimulated the root system and growth of three different plant species in the Brassicaceae family, including Arabidopsis thaliana, mustard, and rapeseed. The bacterium produced auxin, nitric oxide, siderophores and showed ACC deaminase activity. In addition to activating an auxin response in the plant, S. sediminicola Dae20 exhibited the ability to modulate other plant hormones, such as abscisic acid, jasmonic acid and salicylic acid, which are critical for plant development and defense responses. This study highlights the multifunctional properties of S. sediminicola Dae20 as a promising PGPR and underscores the importance of identifying effective and versatile beneficial bacteria to improve plant nutrition and promote sustainable agricultural practices.

“…Rhodanobacter, found mainly in M. kobi root, is a genus of bacteria with various roles in different environments, such as nitrogen fixation (Wang et al 2020;Lv et al 2021). Rhodanobacter produced IAA that increased nitrogen uptake from the soil and used both N2 and fixed nitrogen as nitrogen sources, reducing the energetic costs of nitrogen fixation (Inomura et al 2018).…”

Abstract. Pangastuti A, Pitoyo A, Susilowati A, Meisari R, Yuliana I, Aulia K, Puspitasari LP, Rusiani, Prasojo H. 2023. Diversity of root bacterial community associated with seven orchid species from Mount Merbabu National Park, Central Java, Indonesia. Biodiversitas 24: 5676-5684. Indonesia has a high diversity of wild orchids. One of the orchid habitats that has not been widely explored is Mount Merbabu National Park (TNGMb), Central Java, Indonesia. The dependence of orchids on specific microorganisms for survival and growth, especially during early development, has not been widely studied. Endophytes, such as bacteria, can help the host plant grow, tolerate stress, resist disease, acquire nutrients, or form symbiotic relationships. However, bacterial endophytes associated with orchids have not been extensively explored. This research examined the diversity of bacteria associated with orchid roots in Mount Merbabu National Park using a culture-independent method. Seven orchid species were sampled for root bacterial community analysis, that identified as Spathoglottis plicata, Dendrobium sagittatum, Malaxis kobi, Apendicula alba, Pholidota carnea, Dendrobium tenellum, and Bulbophyllum compressa. Bacterial diversity in all orchid roots was high, with several dominant bacterial species. Proteobacteria, Firmicutes, Bacteriodota, and Actinobacteriota were the four most abundant phyla, with Proteobacteria having the highest abundance (37 to 90%) in all samples. The top ten bacteria genera were Pseudomonas, Serratia, Rhodanobacter, Acinetobacter, Escherichia, Bifidobacterium, Clostridium, Parabulkholderia, Faecalibacterium, and Muribaculaceae family that could not be identified at the genus level. Overall, 61, 42, 838, 98, 78, 973, and 1383 OTUs were unique to S. plicata, D. sagittatum, M. kobi, A. alba, P. carnea, D. tenellum, and B. compressa, respectively, whereas all seven species shared 335 OTUs. Our research suggested that environmental factors and the host plant's genetics affect the plant microbiome's composition and diversity. These elements might be essential for ecosystem function and conservation.
