Evaluation and redesign of the primers for detecting nitrogen cycling genes in environments

Methods in Ecology and Evolution, Volume 13, Issue 9, Page 1976-1989, September 2022., 2022
Abstract A better understanding of how nitrogen (N) cycling genes are involved in ecological processes is one of the crucial areas of microbial ecology. Currently, most molecular biological techniques investigating N cycling genes in the environment heavily rely on the accuracy of the polymerase chain reaction (PCR) primers; however, their specificity ...

Nitrogen deposition does not exacerbate phosphorus limitation of rhizosphere microbes in subalpine forests

Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

Elevation, soil pH and calcium availability shape regional and local scale spatial patterns of PhoD gene abundance in tropical and subtropical forests

Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

模拟氮沉降对华北落叶松人工林土壤微生物碳和微生物氮的动态影响

Shuitu Baochi Xuebao, 2020
为揭示过量的大气氮沉降对华北落叶松人工林土壤微生物碳、氮和土壤呼吸的影响，通过对照（N0：0 g/（m2·a））、轻度施氮（N1：8 g/（m2·a））、重度施氮（N2：15 g/（m2·a））3个外源施氮水平下5年的野外定点试验和观测，模拟过量氮沉降条件下华北落叶松人工林土壤微生物碳、氮和土壤呼吸的变化，旨在阐明林下土壤微生物和呼吸对过量氮沉降的响应及其对土壤碳氮循环的影响。结果表明：在5—10月生长季中，土壤微生物碳和氮的平均含量分别为1 098.93，97.31 mg/kg ...

Effects of Cadmium on Soil Microbial Biomass and Enzyme Activities in Rhizosphere of the Kandelia candel Seedlings [PDF]

, 2009
近年来，红树林湿地重金属污染问题越来越突出，日益引起了人们的关注。根际是物质交换频繁的特殊微型生态区域，是重金属进入红树植株内部的必经之路。根际微域复杂的微生物对植物的生长非常重要，并与重金属的吸收、转化和迁移等生态化学行为及毒理效应密切相关。然而有关红树林根际微生物对重金属胁迫的响应的研究鲜见报道，重金属污染对红树植物根际的微生物生态效应我们仍然所知甚少。本研究通过根箱盆栽红树植物秋茄（Kandeliacandel(L.)Druce）幼苗，分离根际与全土区域 ...

Factors influencing fine roots decomposition rates in response to nitrogen addition vary across root characteristics

Functional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...

Altered nutrient cycling functionality in seagrass meadows under a simulated future marine heatwave event

New Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.
Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,

Arbuscular mycorrhizal fungus reshapes the rhizosphere microbiome of alfalfa in response to above‐ground attack by aphids and a fungal plant pathogen

Functional Ecology, Volume 39, Issue 8, Page 2149-2169, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants assemble beneficial rhizosphere microbiomes through a ‘cry for help’ mechanism upon pathogen or insect herbivore attack. The arbuscular mycorrhizal fungi (AMF) can influence the composition of microbial communities in the plant rhizosphere. However, their impacts
