Rare Biosphere(稀有生物圈)研究综述
Rare Biosphere 稀有生物圈 - Biofilms in all MBfRs had high microbial diversity that was influenced by the “rare biosphere” (RB), phylotypes with relative abundance less than 1%. [1] However, the “rare biosphere” of the oral microbiome, including fungi, has been sparsely investigated. [2] members of the rare biosphere). [3] Soil biogeochemical processes are not only gauged by the dominant taxa in the microbiome but also depend on the critical functions of its 'rare biosphere' members. [4] Also, we observed a rare biosphere of novel taxa without clear taxonomic standing. [5] These bacterial shifts in the ileum were mainly the result of compositional changes in the rare biosphere (unweighted UniFrac), while in the cecum, treatment affected both majority and minority bacterial groups (weighted and unweighted UniFrac). [6] Metagenomic analysis of the BCN community challenged with ADOC showed a significant growth of Methylophaga and other gammaproteobacterial taxa belonging to the rare biosphere. [7] There is likely an enrichment in ecological functions within the rare biosphere, considering this high contribution of deterministic processes in the assembly. [8] Often, the long “tail” of the rank-abundance plots of microbial communities constitutes the so-called “rare biosphere,” microorganisms that are highly diverse but are typically found in low abundance in these communities. [9] Thus, we have isolated a novel member of the 'rare biosphere', which endures the extreme conditions and may play a significant role in the degradation of detrital organic matter sinking into the sulfidic waters of the Black Sea. [10] We used amplicon sequencing of bark from the medicinal plant Eucommia ulmoides collected across nine distinct biogeographical regions in China, and comprehensively analyzed the diversity, rare biosphere and core taxa of bark fungi. [11] On the one hand, the 2-HP-acclimated biomass was richer and dominated by a rare biosphere, or genera having <0. [12] A very low number of taxa were abundant and shared between all sites, whereas the rare biosphere was more phylogenetically diverse (FPD index) and phylogenetically disperse (PSC index) than the abundant taxa for both analyzed libraries. [13] , polycyclic aromatic hydrocarbons) as well as the need to investigate the role of the rare biosphere in ecosystem functioning. [14] Although biofilms should be supplied by the planktonic (ultra) rare biosphere, source tracking could only detect small contributions of FL or PA taxa to B communities. [15] Soil bacterial and fungal communities often comprise the “abundant biosphere” and “rare biosphere”, which co-exist in soil aggregates to form a complex system of inter-species interactions. [16] Potential oil-degrading genera showed a clear succession pattern and were for the most part recruited from the “rare biosphere. [17] Alongside typical cellulose degraders, including members of the Actinobacteria, Bacteroidetes, and Chloroflexi, we found divergent cellulases encoded in the genome of a recently described candidate phylum from the rare biosphere, Goldbacteria, and validated their cellulase activity. [18] The composition of ETBE-enrichment cultures was distinct from their initial water samples, reflecting the importance of the rare biosphere as a reservoir of potential ETBE degraders. [19] The superiority of the MSP platform in revealing the rare biosphere was also evaluated based on amplicon sequencing. [20] 1%) to be considered part of the rare biosphere. [21] Our study emphasizes the importance of the rare biosphere as a critical component of microbial community responses to community coalescence. [22] Amplicon sequence variants that were enriched in hydrothermally influenced bottom waters largely derived from cosmopolitan protists that were present, but rare, in other near-bottom samples, thus highlighting the importance of the rare biosphere. [23] Potential oil-degrading genera showed a clear succession pattern and were for the most part recruited from the “rare biosphere. [24] In addition, through full-length analysis, Conexibacter-like sequences, commonly identified by environmental metagenomics among the rare biosphere, were detected. [25] This rare biosphere now starts to be better described both in its composition and functional attributes, and its ecology is slowly unveiled. [26] The majority of MAGs linked to oiled ecosystems are members of the rare biosphere in non-oiled samples, except for the Gulf of Mexico (GoM) which appears to be primed for oil biodegradation. [27] Our study emphasizes the importance of the rare biosphere as a critical component of community resilience. [28] Ecological roles of “rare biosphere” (RB) were rarely discussed in alpine grassland ecosystems. [29] ) that specificity of plastics biofilms are rather related to members of the rare biosphere. [30] Natural microbial communities consist of a limited number of abundant species and an extraordinarily diverse population of rare species referred to as the rare biosphere. [31]所有 MBfR 中的生物膜都具有高度的微生物多样性，受“稀有生物圈”（RB）的影响，相对丰度低于 1% 的种系型。 [1] 然而，对包括真菌在内的口腔微生物群的“稀有生物圈”的研究却很少。 [2] 稀有生物圈的成员）。 [3] 土壤生物地球化学过程不仅取决于微生物组中的主要分类群，还取决于其“稀有生物圈”成员的关键功能。 [4] 此外，我们观察到一个罕见的新分类群生物圈，没有明确的分类地位。 [5] 回肠中的这些细菌变化主要是稀有生物圈（未加权 UniFrac）中成分变化的结果，而在盲肠中，治疗影响了多数和少数细菌群（加权和未加权 UniFrac）。 [6] 对受到 ADOC 挑战的 BCN 群落进行的宏基因组分析显示，嗜甲基菌和其他属于稀有生物圈的 gammaproteobacterial 类群显着增长。 [7] 考虑到组装中确定性过程的这种高贡献，稀有生物圈内的生态功能可能会有所丰富。 [8] 通常，微生物群落的等级丰度图的长“尾巴”构成了所谓的“稀有生物圈”，即高度多样化但在这些群落中通常以低丰度发现的微生物。 [9] 因此，我们分离出了“稀有生物圈”的一个新成员，它能够承受极端条件，并可能在沉入黑海硫化水中的碎屑有机物降解中发挥重要作用。 [10] 我们对采集自中国九个不同生物地理区域的药用植物杜仲树皮进行扩增子测序，综合分析了树皮真菌的多样性、稀有生物圈和核心类群。 [11] 一方面，2-HP 驯化的生物量更丰富，并且由稀有的生物圈或小于 0 的属主导。 [12] 非常少量的分类群丰富并在所有站点之间共享，而稀有生物圈比两个分析库的丰富分类群在系统发育上更多样化（FPD 指数）和系统发育分散（PSC 指数）。 [13] ，多环芳烃）以及需要研究稀有生物圈在生态系统功能中的作用。 [14] 尽管生物膜应该由浮游（超）稀有生物圈提供，但源跟踪只能检测到 FL 或 PA 分类群对 B 群落的小贡献。 [15] 土壤细菌和真菌群落通常由“丰富的生物圈”和“稀有的生物圈”组成，它们在土壤团聚体中共存，形成一个复杂的物种间相互作用系统。 [16] 潜在的石油降解属显示出明显的演替模式，并且大部分来自“稀有生物圈”。 [17] 除了典型的纤维素降解剂，包括放线菌、拟杆菌和绿曲菌的成员，我们还在最近描述的来自稀有生物圈的候选门金细菌的基因组中发现了不同的纤维素酶，并验证了它们的纤维素酶活性。 [18] ETBE 富集培养物的组成与其最初的水样不同，反映了稀有生物圈作为潜在 ETBE 降解物库的重要性。 [19] MSP平台在揭示稀有生物圈方面的优越性也基于扩增子测序进行了评估。 [20] 1%）被视为稀有生物圈的一部分。 [21] 我们的研究强调了稀有生物圈作为微生物群落对群落合并反应的关键组成部分的重要性。 [22] 富含热液影响的底水的扩增子序列变体主要来自世界性原生生物，这些原生生物在其他近底样品中存在但很少见，因此突出了稀有生物圈的重要性。 [23] 潜在的石油降解属显示出明显的演替模式，并且大部分来自“稀有生物圈”。 [24] 此外，通过全长分析，检测到了稀有生物圈中环境宏基因组学普遍鉴定的类锥体杆菌序列。 [25] 这个稀有的生物圈现在开始在其组成和功能属性上得到更好的描述，它的生态学也慢慢被揭开。 [26] 与石油生态系统相关的大多数 MAG 是非石油样本中稀有生物圈的成员，除了似乎已准备好进行石油生物降解的墨西哥湾 (GoM)。 [27] 我们的研究强调了稀有生物圈作为社区复原力的关键组成部分的重要性。 [28] “稀有生物圈”（RB）的生态作用在高山草原生态系统中很少被讨论。 [29] ）塑料生物膜的特异性与稀有生物圈的成员相当相关。 [30] 自然微生物群落由数量有限的丰富物种和极其多样化的稀有物种种群组成，称为稀有生物圈。 [31]
rare biosphere taxa
Based on microbial interaction networks, communities responded to the disturbance by showing a transition from acetotrophic (Methanotrichaceae and Methanosarcinaceae) to methylotrophic methanogens (Methanomassiliicoccaceae and Methanobacteriaceae) and a fluctuation in rare biosphere taxa. [1] ADOC exposure also changed the composition of microbial communities, through stimulation of rare biosphere taxa. [2]基于微生物相互作用网络，群落通过显示从产甲烷菌（Methanotrichaceae 和 Methanosarcinaceae）到甲基营养产甲烷菌（Methanomassiliicoccaceae 和 Methanobacteriaceae）的转变以及稀有生物圈分类群的波动来应对干扰。 [1] ADOC 暴露还通过刺激稀有生物圈类群改变了微生物群落的组成。 [2]
