| 1 | QMEC:a tool for high-throughput quantitative assessment of microbial functional potential in C,N,P,and S biogeochemical cycling显示文摘Microorganisms are major drivers of elemental cycling in the biosphere. Determining the abundance of microbial functional traits involved in the transformation of nutrients, including carbon(C), nitrogen(N), phosphorus(P) and sulfur(S), is critical for assessing microbial functionality in elemental cycling. We developed a high-throughput quantitative-PCR-based chip, Quantitative microbial element cycling(QMEC), for assessing and quantifying the genetic potential of microbiota to mineralize soil organic matter and to release C, N, P and S. QMEC contains 72 primer pairs targeting 64 microbial functional genes for C, N, P, S and methane metabolism. These primer pairs were characterized by high coverage(average of 18–20 phyla covered per gene)and sufficient specificity(>70% match rate) with a relatively low detection limit(7–102 copies per run). QMEC was successfully applied to soil and sediment samples, identifying significantly different structures, abundances and diversities of the functional genes(P<0.05). QMEC was also able to determine absolute gene abundance. QMEC enabled the simultaneous qualitative and quantitative determination of 72 genes from 72 samples in one run, which is promising for comprehensively investigating microbially mediated ecological processes and biogeochemical cycles in various environmental contexts including those of the current global change. | Bangxiao Zheng Yongguan Zhu Jordi Sardans Josep Penuelas Jianqiang Su | 2018 | Science China(Life Sciences)2018，61，12： | 18 |
| 2 | Loss of soil microbial diversity exacerbates spread of antibiotic resistance显示文摘Loss of biodiversity is a major threat to the ecosystem processes upon which society depends.Natural ecosystems differ in their resistance to invasion by alien species,and this resistance can depend on the diversity in the system.Little is known,however,about the barriers that microbial diversity provides against microbial invasion.The increasing prevalence of antibioticresistant bacteria is a serious threat to public health in the 21st century.We explored the consequences of the reduction in soil microbial diversity for the dissemination of antibiotic resistance.The relationship between this diversity and the invasion of antibiotic resistance was investigated using a dilution-to-extinction approach coupled with high-capacity quantitative PCR.Microbial diversity was negatively correlated with the abundance of antibiotic-resistance genes,and this correlation was maintained after accounting for other potential drivers such as incubation time and microbial abundance.Our results demonstrate that high microbial diversity can act as a biological barrier resist the spread of antibiotic resistance.These results fill a critical gap in our understanding of the role of soil microbial diversity in the health of ecosystems. | Qing-Lin Chen Xin-Li An Bang-Xiao Zheng Michael Gillings Josep Penuelas Li Cui Jian-Qiang Su Yong-Guan Zhu | 2019 | Soil Ecology Letters2019，1，1： | 4 |
| 3 | 喜马拉雅山区高山冰缘植物并不能从变暖中受益显示文摘普遍认为变暖有利于高山植被生态系统,并已经导致冰缘植物向高海拔的扩张.珠峰山谷金字塔气象站(海拔5050 m)1994~2018的气象记录显示,高海拔山区呈显著的暖干化趋势.然而,我们依然不清楚暖干化是否对冰缘植被更新和分布造成显著影响?本研究在喜马拉雅山中段3个山谷建立了8块(30 m×120 m)滇藏方枝柏(Juniperus indica)和高山柏(Juniperus squamata)灌木线样地(海拔介于4344~5074 m之间).样地调查揭示,自20世纪90年代之前所有样地种群更新呈增加的趋势,然而90年代以来更新持续下降.种群更新与春季、夏季温度之间呈现显著的负相关关系,暗示了暖干化加剧了水分胁迫,并限制了种群的更新.另外,近60年来所有灌木线位置稳定.近30年遥感数据也证实,研究区冰缘植被无变绿趋势,甚至出现2%-6%的植被生长减弱现象.因此,进一步研究应该探讨冰缘植被生长减弱对喜马拉雅山区水循环和生物多样性的影响. | Shalik Ram Sigdel Jayram Pandey 梁尔源 Sher Muhammad Flurin Babst Steven W.Leavitt 沈妙根 朱海峰 Franco Salerno 朴世龙 J.Julio Camarero Josep Penuelas | 2021 | Science Bulletin2021，66，18： | 2 |
| 4 | 纳米塑料对人体健康的影响显示文摘Plastics are ubiquitous. Their role as a cost-effective, chemically stable, versatile multipurpose material precluded early attempts to regulate plastic wastes and facilitated the, now widespread, planetary contamination. Left to slow UV decay and thermooxidative weathering, large plastics chip away into less than 5 mm fragments, or microplastics, which, in turn, can degrade further into nanoplastics. In the manufacturing process, several components,such as catalysts, solvents, stabilizers。 | Mariana Teles Joan Carles Balasch Miguel Oliveira Jordi Sardans Josep Penuelas | 2020 | Science Bulletin2020，65，23： | 2 |
