| 1 | Development and utilization of a new chemically-induced soybean library with a high mutation density显示文摘Mutagenized populations have provided important materials for introducing variation and identifying gene function in plants. In this study, an ethyl methanesulfonate(EMS)-induced soybean(Glycine max) population,consisting of 21,600 independent M_2 lines, was developed.Over 1,000 M_(4(5))families, with diverse abnormal phenotypes for seed composition, seed shape, plant morphology and maturity that are stably expressed across different environments and generations were identified. Phenotypic analysis of the population led to the identification of a yellow pigmentation mutant, gyl, that displayed significantly decreased chlorophyll(Chl) content and abnormal chloroplast development. Sequence analysis showed that gyl is allelic to Minn Gold, where a different single nucleotide polymorphism variation in the Mg-chelatase subunit gene(ChlI1a) results in golden yellow leaves. A cleaved amplified polymorphic sequence marker was developed and may be applied to marker-assisted selection for the golden yellow phenotype in soybean breeding. We show that the newly developed soybean EMS mutant population has potential for functional genomics research and genetic improvement in soybean. | Zhongfeng Li Lingxue Jiang Yansong Ma Zhongyan Wei Huilong Hong Zhangxiong Liu Jinhui Lei Ying Liu Rongxia Guan Yong Guo Longguo Jin Lijuan Zhang Yinghui Li Yulong Ren Wei He Ming Liu Nang Myint Phyu Sin Htwe Lin Liu Bingfu Guo Jian Song Bing Tan Guifeng Liu Maiquan Li Xianli Zhang Bo Liu Xuehui Shi Sining Han Sunan Hua Fulai Zhou Lili Yu Yanfei Li Shuang Wang Jun Wang Ruzhen Chang Lijuan Qiu | 2017 | Journal of Integrative Plant Biology2017，59，1： | 6 |

| 3 | 3个小型高原湖泊水陆交错带中植物叶片pH值变异及其潜在影响因素显示文摘陆生植物叶片pH值是与植物生理功能和养分利用状况息息相关的重要植物属性,并随植物功能型和环境的变化而变化。然而,水生植物叶片pH值的变异特征及其与陆生植物间的差异性仍不清楚。在3个自然形成的小型高原湖泊的湖滨植物群落中,我们采集植物、土壤和湖水样品,检测了植物叶片pH值与碳、氮含量以及环境条件(水或土壤pH值、土壤水位状况)。从植物功能型和群落两个水平分析了湖滨植物叶pH值沿水分梯度的变化及其潜在影响因素。研究结果表明,不同类型的水生植物,以及水生、沼生和陆生环境中生长的植物的叶pH存在较大差异;浮叶植物叶片pH值(4.21±0.05)显著低于挺水植物(5.71±0.07)和沉水植物(5.82±0.06);水生草本植物叶片pH值(5.43±0.10)显著低于沼生草本植物(6.12±0.07)和陆生草本植物(5.74±0.05);陆生草本植物叶片pH值显著高于木本植物。植物功能群间叶片pH值的变异可能与叶片的结构、光利用特性和养分特性有关。群落水平的结果与植物功能型水平相一致:水生群落叶片pH值显著低于陆生群落。群落水平叶片pH值可能主要受物种组成、水分条件和环境pH值的影响。本研究首次探索了水生植物的pH值,并且在景观尺度上对比了不同功能型植物的叶片pH值,为深入探索植物pH值变异机制以及其在水生和湿地生态系统中的生态意义提供参考。 | Sining Liu Shenqun An Zhengbing Yan Junpeng Ren Xiaoqian Lu Feiyang Ge Wenxuan Han | 2021 | Journal of Plant Ecology2021，14，3： | 1 |
| 4 | Immediate and legacy effects of snow exclusion on soil fungal diversity and community composition显示文摘Background:Soil fungi play crucial roles in ecosystem functions.However,how snow cover change associated with winter warming affects soil fungal communities remains unclear in the Tibetan forest.Methods:We conducted a snow manipulation experiment to explore immediate and legacy effects of snow exclusion on soil fungal community diversity and composition in a spruce forest on the eastern Tibetan Plateau.Soil fungal communities were performed by the high throughput sequencing of gene-fragments.Results:Ascomycota and Basidiomycota were the two dominant fungal phyla and Archaeorhizomyces,Aspergillus and Amanita were the three most common genera across seasons and snow manipulations.Snow exclusion did not affect the diversity and structure of soil fungal community in both snow-covered and snow-free seasons.However,the relative abundance of some fungal communities was different among seasons.Soil fungal groups were correlated with environmental factors(i.e.,temperature and moisture)and soil biochemical variables(i.e.,ammonium and enzyme).Conclusions:These results suggest that the season-driven variations had stronger impacts on soil fungal community than short-term snow cover change.Such findings may have important implications for soil microbial processes in Tibetan forests experiencing significant decreases in snowfall. | Li Zhang Yuzhi Ren Kaijun Yang Zhijie Li Bo Tan Yang Liu Han Li Chengming You Sining Liu Lixia Wang Rui Yin Jian Zhang Zhenfeng Xu | 2021 | Forest Ecosystems2021，8，2： | 1 |
| 5 | Nitrogen addition mediates the response of foliar stoichiometry to phosphorus addition: a meta-analysis显示文摘Background:Changes in foliar nitrogen(N)and phosphorus(P)stoichiometry play important roles in predicting the efects of global change on ecosystem structure and function.However,there is substantial debate on the efects of P addition on foliar N and P stoichiometry,particularly under diferent levels of N addition.Thus,we conducted a global meta-analysis to investigate how N addition alters the efects of P addition on foliar N and P stoichiometry across different rates and durations of P addition and plant growth types based on more than 1150 observations.Results:We found that P addition without N addition increased foliar N concentrations,whereas P addition with N addition had no efect.The positive efects of P addition on foliar P concentrations were greater without N addition than with N addition.Additionally,the efects of P addition on foliar N,P and N:P ratios varied with the rate and duration of P addition.In particular,short-term or low-dose P addition with and without N addition increased foliar N concentration,and the positive efects of short-term or low-dose P addition on foliar P concentrations were greater without N addition than with N addition.The responses of foliar N and P stoichiometry of evergreen plants to P addition were greater without N addition than with N addition.Moreover,regardless of N addition,soil P availability was more efective than P resorption efciency in predicting the changes in foliar N and P stoichiometry in response to P addition.Conclusions:Our results highlight that increasing N deposition might alter the response of foliar N and P stoichiometry to P addition and demonstrate the important efect of the experimental environment on the results.These results advance our understanding of the response of plant nutrient use efciency to P addition with increasing N deposition. | Chengming You Changhui Peng Zhenfeng Xu Yang Liu Li Zhang Rui Yin Lin Liu Han Li Lixia Wang Sining Liu Bo Tan Paul Kardol | 2021 | Ecological Processes2021，10，1： | 0 |
| 6 | Do root modules still exist after they die?显示文摘Background:The terminal branch orders of plant root systems are increasingly known as an ephemeral module.This concept is crucial to recognize belowground processes.However,it is unknown if root modules still exist after they die?Methods:The decomposition patterns of the first five root orders were observed for 3 years using a branch-order classification,a litter-bag method and sequential sampling in a common subalpine tree species(Picea asperata)of southwestern China.Results:Two root modules were observed during the 3-year incubation.Among the first five branch orders,the first three order roots exhibited temporal patterns of mass loss,nutrients and stoichiometry distinct from their woody mother roots throughout the experimental period.This study,for the first time,reported the decomposition pattern of each individual root order and found a similar decomposition dynamic among ephemeral root branches in a forest tree species.Conclusions:Results from this study suggest that root modules may also exist after death,while more data are needed for confirmation.The findings may further advance our understanding of architecture-associated functional heterogeneity in the fine-root system and also improve our ability to predict belowground processes. | Jihong Li Chengming You Li Zhang Han Li Bo Tan Yang Liu Lixia Wang Sining Liu Zhenfeng Xu | 2021 | Forest Ecosystems2021，8，2： | 0 |
| 7 | Waste-Derived Catalysts for Water Electrolysis:Circular Economy-Driven Sustainable Green Hydrogen Energy显示文摘The sustainable production of green hydrogen via water electrolysis necessitates cost-effective electrocatalysts.By following the circular economy principle,the utilization of waste-derived catalysts significantly promotes the sustainable development of green hydrogen energy.Currently,diverse waste-derived catalysts have exhibited excellent catalytic performance toward hydrogen evolution reaction(HER),oxygen evolution reaction(OER),and overall water electrolysis(OWE).Herein,we systematically examine recent achievements in waste-derived electrocatalysts for water electrolysis.The general principles of water electrolysis and design principles of efficient electrocatalysts are discussed,followed by the illustration of current strategies for transforming wastes into electrocatalysts.Then,applications of waste-derived catalysts(i.e.,carbon-based catalysts,transitional metal-based catalysts,and carbon-based heterostructure catalysts)in HER,OER,and OWE are reviewed successively.An emphasis is put on correlating the catalysts’structure-performance relationship.Also,challenges and research directions in this booming field are finally highlighted.This review would provide useful insights into the design,synthesis,and applications of waste-derived electrocatalysts,and thus accelerate the development of the circular economy-driven green hydrogen energy scheme. | Zhijie Chen Sining Yun Lan Wu Jiaqi Zhang Xingdong Shi Wei Wei Yiwen Liu Renji Zheng Ning Han Bing-Jie Ni | 2023 | Nano-Micro Letters2023，15，1： | 0 |
| 8 | 植物叶片pH值的测定及样品预处理和保存方法的比较研究显示文摘植物叶片pH值是叶片能量运转、新陈代谢、养分平衡等生理活动的重要调节因素。但目前尚缺乏一套合适的植物叶片样品的保存和测试方法,能同时满足叶片样品的长期保存和接近鲜叶片pH值测定的要求。本文通过探索植物叶样品的预处理和保存方式以及叶:水混合比例对叶片pH测定值的影响,提出一种能够长期保存植物叶片,同时对叶片pH值影响较小的测定方法,并且建立不同处理方法间的转换关系。本研究采集多种植物的叶片样品,并分别进行短期冷藏、冷冻和烘干处理保存,以刚采摘的新鲜绿色叶片作为对照,研究叶片样品不同保存方式对其pH值的影响。对烘干绿色叶片按叶片和水1:8的体积比和1:10的质量比分别进行pH值测定,对冷冻叶片:水按质量比为1:10和1:15的比例分别进行测定,分析不同加水比例对所测叶片样品pH值的影响。结果表明,短期冷藏和冷冻处理对植物叶片pH值的测量结果没有显著影响,但是烘干处理一般会使测定值偏高。因此,在长时间的野外采样工作中,通过便携式冷藏箱对植物样品进行冷冻保存,是保持叶片样品pH值稳定、即更接近新鲜叶pH测量值的较好的样品保存方式。对于长时间野外采样,冷冻预处理是植物叶样品保存的最佳选择;而冷藏预处理是短时间保存的最佳选择。不同的叶片:水比例对pH测量值存在显著影响:样品稀释比例越高,氢离子浓度越低,测量到的叶片pH值越大。因此,为了建立现有不同植物叶pH值测量方法之间的联系,本文为叶片样品的不同前处理和测量方式提供了转换关系。本研究结果将有助于植物叶片pH值的研究,从而提高对这一功能性状的认识。 | Sining Liu Jiashu Chen Wenxuan Han | 2022 | Journal of Plant Ecology2022，15，4： | 0 |
| 9 | Nitrogen addition promotes foliar litterfall and element return in a subtropical forest,southwestern China显示文摘Nitrogen deposition has a considerable impact on biogeochemical cycling in terrestrial ecosystems.However,how litter production and element return respond to N addition remains poorly understood in nitrogen-rich subtropical regions.In this study,a 4-year nitrogen addition experiment explored its eff ects on foliar litter production and carbon,nitrogen and phosphorus in a subtropical Michelia wilsonii forest.A clear seasonal pattern in foliar litterfall was observed,regardless of nitrogen treatments,with a peak in spring and a smaller one in autumn.Foliar litter increased with increasing nitrogen but did not aff ect litter carbon concentrations and often decreased nitrogen and phosphorous concentrations.The eff ect of nitrogen addition was dependent on time(month/year).Carbon,nitrogen and phosphorous return showed similar bimodal seasonal patterns.Nitrogen addition increased carbon and nitrogen return but did not aff ect phosphorous.Our results suggest that the addition of nitrogen stimulates carbon and nutrient return via litterfall. | Yue Zhang Shichen Xiong Chengming You Sining Liu Lixia Wang Li Zhang Han Li Bo Tan Yang Liu Zhenfeng Xu | 2023 | Journal of Forestry Research2023，34，4： | 0 |
