Abstract Geobacteraceae is an important dissimilatory Fe(III) reducer that affects the cycles of multiple elements. However, the way in which different long-term fertilization regimes influence the Geobacteraceae community in paddy soils remains unknown. Therefore, the objective of this study was to explore the responses of Geobacteraceae community in paddy soil to long-term chemical (nitrogen, phosphorus, and potassium) and/or organic (manure) fertilization practices. Illumina sequencing results showed that the species richness and diversity of Geobacteraceae community were not significantly changed by fertilizer treatments. Geobacteraceae in the treatments consisted of Geobacter (accounting for 90%–95% of total reads) and Geothermobacter genera (5%–10%), and all fertilizer treatments induced a significant (P

长期施肥下水稻土土杆菌科群落的丰度、多样性和结构

摘要 地杆菌科是影响多种元素循环的重要异化Fe(III)还原剂。然而,不同的长期施肥制度如何影响水稻土壤中地杆菌科群落的方式仍然未知。因此,本研究的目的是探索稻田土壤中地杆菌科群落对长期化学(氮、磷和钾)和/或有机(粪肥)施肥实践的响应。Illumina测序结果表明,施肥处理对地杆菌科群落物种丰富度和多样性没有显着影响。处理中地杆菌科由地杆菌(占总读数的 90%–95%)和地热杆菌属(5%–10%)组成,所有肥料处理均诱导显着(P
