摘要

放线菌植物的根瘤是固氮菌共生体(即弗兰科菌)和少量其他微生物的家园。这些微生物包括真菌内生菌和非弗兰克菌。人们对这些根瘤内微生物群落的分类和功能多样性了解不多。在这项研究中,我们调查并分析了一起生长的红桤木和西特卡桤木根瘤中可培养的非弗兰基菌真菌和细菌内生菌。我们研究了它们的分类多样性、共生情况、宿主之间的差异以及潜在的功能作用。我们首次报告了赤杨根瘤中的大量真菌内生菌。其中包括 Sporothrix guttuliformis、Fontanospora sp.、Cadophora melinii、未分类的 Cadophora、Ilyonectria destructans、未分类的 Gibberella、Nectria ramulariae、未分类的 Trichoderma、Mycosphaerella tassiana、未分类的 Talaromyces、Coniochaeta sp.和 Sistotrema brinkmanii。我们还首次报告了几个细菌属:Collimonas、Psychrobacillus 和 Phyllobacterium。此外,我们还是第二次报告沙雷氏菌属,第一次报告最近发表于 2023 年。假单胞菌是最常分离出的细菌属,并发现它与真菌和细菌共同栖息于单个结核中。我们发现真菌内生菌群落因宿主物种而异,而细菌内生菌群落则不然。

Root nodules of red alder (Alnus rubra) and sitka alder (Alnus viridis ssp. sinuata) are inhabited by taxonomically diverse cultivable microbial endophytes

Root nodules of red alder (Alnus rubra) and sitka alder (Alnus viridis ssp. sinuata) are inhabited by taxonomically diverse cultivable microbial endophytes

The root nodules of actinorhizal plants are home to nitrogen-fixing bacterial symbionts, known as Frankia, along with a small percentage of other microorganisms. These include fungal endophytes and non-Frankia bacteria. The taxonomic and functional diversity of the microbial consortia within these root nodules is not well understood. In this study, we surveyed and analyzed the cultivable, non-Frankia fungal and bacterial endophytes of root nodules from red and Sitka alder trees that grow together. We examined their taxonomic diversity, co-occurrence, differences between hosts, and potential functional roles. For the first time, we are reporting numerous fungal endophytes of alder root nodules. These include Sporothrix guttuliformis, Fontanospora sp., Cadophora melinii, an unclassified Cadophora, Ilyonectria destructans, an unclassified Gibberella, Nectria ramulariae, an unclassified Trichoderma, Mycosphaerella tassiana, an unclassified Talaromyces, Coniochaeta sp., and Sistotrema brinkmanii. We are also reporting several bacterial genera for the first time: Collimonas, Psychrobacillus, and Phyllobacterium. Additionally, we are reporting the genus Serratia for the second time, with the first report having been recently published in 2023. Pseudomonas was the most frequently isolated bacterial genus and was found to co-inhabit individual nodules with both fungi and bacteria. We found that the communities of fungal endophytes differed by host species, while the communities of bacterial endophytes did not.

期刊介绍: MicrobiologyOpen is a peer reviewed, fully open access, broad-scope, and interdisciplinary journal delivering rapid decisions and fast publication of microbial science, a field which is undergoing a profound and exciting evolution in this post-genomic era. The journal aims to serve the research community by providing a vehicle for authors wishing to publish quality research in both fundamental and applied microbiology. Our goal is to publish articles that stimulate discussion and debate, as well as add to our knowledge base and further the understanding of microbial interactions and microbial processes. MicrobiologyOpen gives prompt and equal consideration to articles reporting theoretical, experimental, applied, and descriptive work in all aspects of bacteriology, virology, mycology and protistology, including, but not limited to: - agriculture - antimicrobial resistance - astrobiology - biochemistry - biotechnology - cell and molecular biology - clinical microbiology - computational, systems, and synthetic microbiology - environmental science - evolutionary biology, ecology, and systematics - food science and technology - genetics and genomics - geobiology and earth science - host-microbe interactions - infectious diseases - natural products discovery - pharmaceutical and medicinal chemistry - physiology - plant pathology - veterinary microbiology We will consider submissions across unicellular and cell-cluster organisms: prokaryotes (bacteria, archaea) and eukaryotes (fungi, protists, microalgae, lichens), as well as viruses and prions infecting or interacting with microorganisms, plants and animals, including genetic, biochemical, biophysical, bioinformatic and structural analyses. The journal features Original Articles (including full Research articles, Method articles, and Short Communications), Commentaries, Reviews, and Editorials. Original papers must report well-conducted research with conclusions supported by the data presented in the article. We also support confirmatory research and aim to work with authors to meet reviewer expectations. MicrobiologyOpen publishes articles submitted directly to the journal and those referred from other Wiley journals.
