氨氧化古菌（AOA）是酸性农业土壤中具有重要生态意义的硝化菌。两个 AOA 系统发育分支，属于 Nitrososphaerales 目级谱系（分支 C11；也分类为 NS-Gamma-2.3.2）和 Candidatus Nitrosotaleaceae 科级谱系（分支 C14；NT-Alpha-1.1.1），通常在低 pH 土壤中主导 AOA 种群。本研究旨在探讨不同施肥历史对土壤中嗜酸AOA群落组成和活性的影响。对 20 多年来来自相同土壤但使用不同类型肥料进行改良的 6 个低 pH 农田进行了氨单加氧酶基因 (amoA) 的高通量测序，并测量了这些土壤的硝化率。在这些施肥的酸性土壤中，硝化作用可能主要由亚硝化球菌目 AOA 和氨氧化细菌主导，而 Ca。亚硝基禾科AOA活性不显着。在 Nitrososphaerales AOA 中，群落组成因受精历史而异，其中 Nitrososphaerales C11 仅占群落的一小部分。这项研究表明，长期土壤施肥可能通过土壤 pH 值变化或通过氮、钾和磷的直接影响来选择不同的嗜酸硝化菌群落。不同施肥土壤之间的群落组成比较也突显了对环境变化具有不同程度稳定性的AOA系统发育型的存在，有助于理解陆地生态系统中高AOA多样性的维持。在线版本包含可在 10.1007/s00248-021-01763-2 获取的补充材料。
Ammonia oxidising archaea (AOA) are ecologically important nitrifiers in acidic agricultural soils. Two AOA phylogenetic clades, belonging to order-level lineages of Nitrososphaerales (clade C11; also classified as NS-Gamma-2.3.2) and family-level lineage of Candidatus Nitrosotaleaceae (clade C14; NT-Alpha-1.1.1), usually dominate AOA population in low pH soils. This study aimed to investigate the effect of different fertilisation histories on community composition and activity of acidophilic AOA in soils. High-throughput sequencing of ammonia monooxygenase gene (amoA) was performed on six low pH agricultural plots originating from the same soil but amended with different types of fertilisers for over 20 years and nitrification rates in those soils were measured. In these fertilised acidic soils, nitrification was likely dominated by Nitrososphaerales AOA and ammonia-oxidising bacteria, while Ca. Nitrosotaleaceae AOA activity was non-significant. Within Nitrososphaerales AOA, community composition differed based on the fertilisation history, with Nitrososphaerales C11 only representing a low proportion of the community. This study revealed that long-term soil fertilisation selects for different acidophilic nitrifier communities, potentially through soil pH change or through direct effect of nitrogen, potassium and phosphorus. Comparative community composition among the differently fertilised soils also highlighted the existence of AOA phylotypes with different levels of stability to environmental changes, contributing to the understanding of high AOA diversity maintenance in terrestrial ecosystems.
