It remains unclear how N input affects the denitrifying bacterial communities that play a key role in regulating N cycles in various ecosystems. To test our hypothesis-that the abundance and biodiversity of denitrifying bacterial communities decrease with increasing N-we compared the abundance and composition of denitrifying bacteria having nitrous oxide reductase gene (nosZ I) from sediments (0-20 cm) in five experimental ponds with different nitrogen fertilization treatment (TN10, TN20, TN30, TN40, TN50) using quantitative PCR and pyrosequencing techniques. We found that (1) N addition significantly decreased nosZ I gene abundance, (2) the Invsimpson and Shannon indices (reflecting biodiversity) first increased significantly along with the increasing N loading in TN10-TN40 followed by a decrease in TN50, (3) the beta diversity of the nosZ I denitrifier was clustered into three groups along the TN concentration levels: Cluster I (TN50), Cluster II (TN40), and Cluster III (TN10-TN30), (4) the proportions of Alphaproteobacteria and Betaproteobacteria in the high-N treatment (TN50) were significantly lower than in the lower N treatments (TN10-TN30). (5) The TN concentration was the most important factor driving the alteration of denitrifying bacteria assemblages. Our findings shed new light on the response of denitrification-related bacteria to long-term N loading at pond scale and on the response of denitrifying microorganisms to N pollution.", "doi": "10.1007/s00248-022-01971-4", "has_grant": false, "journal": { "title": "MICROBIAL ECOLOGY" }, "license": { "id": "cc-by" }, "publication_date": "2022-01-01", "relations": { "version": [ { "count": 1, "index": 0, "is_last": true, "last_child": { "pid_type": "recid", "pid_value": "258735" }, "parent": { "pid_type": "recid", "pid_value": "258734" } } ] }, "resource_type": { "subtype": "article", "title": "Dergi makalesi", "type": "publication" }, "science_branches": [ "Di\u011fer" ], "title": "Effects of Nitrogen Input on Community Structure of the Denitrifying Bacteria with Nitrous Oxide Reductase Gene (nosZ I): a Long-Term Pond Experiment" }, "owners": [ 1 ], "revision": 1, "stats": { "downloads": 2.0, "unique_downloads": 2.0, "unique_views": 4.0, "version_downloads": 2.0, "version_unique_downloads": 2.0, "version_unique_views": 4.0, "version_views": 4.0, "version_volume": 508.0, "views": 4.0, "volume": 508.0 }, "updated": "2023-07-29T08:16:08.843644+00:00" }
