| 1 | Nitrogen and Phosphorus Dual-Doped Multilayer Graphene as Universal Anode for Full Carbon-Based Lithium and Potassium Ion Capacitors显示文摘Lithium/potassium ion capacitors(LICs/PICs) have been proposed to bridge the performance gap between high-energy batteries and high-power capacitors.However,their development is hindered by the choice,electrochemical performance,and preparation technique of the battery-type anode materials.Herein,a nitrogen and phosphorus dual-doped multilayer graphene(NPG) material is designed and synthesized through an arc discharge process,using low-cost graphite and solid nitrogen and phosphorus sources.When employed as the anode material,NPG exhibits high capacity,remarkable rate capability,and stable cycling performance in both lithium and potassium ion batteries.This excellent electrochemical performance is ascribed to the synergistic effect of nitrogen and phosphorus doping,which enhances the electrochemical conductivity,provides a higher number of ion storage sites,and leads to increased interlayer spacing.Full carbon-based NPG‖LiPF6‖active carbon(AC) LICs and NPG‖KPF6‖AC PICs are assembled and show excellent electrochemical performance,with competitive energy and power densities.This work provides a route for the large-scale production of dual-doped graphene as a universal anode material for high-performance alkali ion batteries and capacitors. | Yuting Luan Rong Hu Yongzheng Fang Kai Zhu Kui Cheng Jun Yan Ke Ye Guiling Wang Dianxue Cao | 2019 | Nano-Micro Letters2019，11，2： | 6 |
| 2 | Lignin provides mechanical support to herbaceous peony(Paeonia lactiflora Pall.)stems显示文摘Stem bending caused by mechanical failure is a major constraint for high-quality herbaceous peony(Paeonia lactiflora Pall.)cut flowers,but little is known about the underlying factors.In this study,two P.lactiflora cultivars,Xixia Yingxue(bending)and Hong Feng(upright),were used to investigate differences in stem bending.The results showed that the stem mechanical strength of Hong Feng was significantly higher than that of Xixia Yingxue,and the thickening of the secondary cell wall and the number of thickened secondary cell wall layers in Hong Feng were significantly higher than those in Xixia Yingxue.Moreover,compared with Xixia Yingxue,Hong Feng showed greater lignification of the cell wall and lignin deposition in the cell walls of the sclerenchyma,vascular bundle sheath and duct.All three types of lignin monomers were detected.The S-lignin,G-lignin,and total lignin contents and the activities of several lignin biosynthesis-related enzymes were higher in Hong Feng than in the other cultivar,and the S-lignin content was closely correlated with stem mechanical strength.In addition,113,974 full-length isoforms with an average read length of 2106 bp were obtained from the full-length transcriptome of P.lactiflora stems,and differential expression analysis was performed based on the comparative transcriptomes of these two cultivars.Ten lignin biosynthesis-related genes,including 26 members that were closely associated with lignin content,were identified,and multiple upregulated and downregulated transcription factors were found to positively or negatively regulate lignin biosynthesis.Consequently,lignin was shown to provide mechanical support to P.lactiflora stems,providing useful information for understanding the formation of P.lactiflora stem strength. | Daqiu Zhao Yuting Luan Xing Xia Wenbo Shi Yuhan Tang Jun Tao | 2020 | Horticulture Research2020，7，1： | 1 |
| 3 | PoWRKY71 is involved in Paeonia ostii resistance to drought stress by directly regulating light-harvesting chlorophyll a/b-binding 151 gene显示文摘Although the functions of WRKY transcription factors in drought resistance are well known,their regulatory mechanisms in response to drought by stabilising photosynthesis remain unclear.Here,a differentially expressed PoWRKY71 gene that was highly expressed in drought-treated Paeonia ostii leaves was identified through transcriptome analysis.PoWRKY71 positively responded to drought stress with significantly enhanced expression patterns and overexpressing PoWRKY71 in tobacco greatly improved plant tolerance to drought stress,whereas silencing PoWRKY71 in P.ostii resulted in a drought-intolerant phenotype.Furthermore,lower chlorophyll contents,photosynthesis,and inhibited expression of photosynthesis-related light-harvesting chlorophyll a/b-binding 151(CAB151)gene were found in PoWRKY71-silenced P.ostii.Meanwhile,a homologous system indicated that drought treatment increased PoCAB151 promoter activity.Interactive assays revealed that PoWRKY71 directly bound on the W-box element of PoCAB151 promoter and activated its transcription.In addition,PoCAB151 overexpressing plants demonstrated increased drought tolerance,together with significantly higher chlorophyll contents and photosynthesis,whereas these indices were dramatically lower in PoCAB151-silenced P.ostii.The above results indicated that PoWRKY71 activated the expression of PoCAB151,thus stabilising photosynthesis via regulating chloroplast homeostasis and chlorophyll content in P.ostii under drought stress.This study reveals a novel drought-resistancemechanism in plants and provides a feasible strategy for improving plant drought resistance via stabilising photosynthesis. | Yuting Luan Zijie Chen Ziwen Fang Xingqi Huang Daqiu Zhao Jun Tao | 2023 | Horticulture Research2023，10，11： | 0 |
| 4 | Selection of Stable Reference Genes for Quantitative Real-Time PCR on Herbaceous Peony (Paeonia lactiflora Pall.) in Response to Drought Stress显示文摘Herbaceous peony(Paeonia lactiflora Pall.),as a high-end cut flower in the international market,has high ornamental and medicinal values.But in Northern China,drought is a major environmental factor influencing the growth and development of P.lactiflora.Quantitative real-time polymerase chain reaction(qRT-PCR)can evaluate gene expression levels under different stress conditions,and stable internal reference is the key for qRT-PCR.At present,there is no systematic screening of internal reference for correcting gene expressions of P.lactiflora in response to drought stress.In this study,10 candidate genes[ubiquitin(UBQ2),UBQ1,elongation factor 1-α(EF-1α),Histidine(His),eukaryotic initiation factor(eIF),tubulin(TUB),actin(ACT),UBQ3,ACT2,RNA polymerase II(RNA Pol II)]were chosen,and 4 analysis methods were used to compare the stabilities for these 10 genes coping with drought stress.Due to the difference of operation methods,the results of different analysis were distinct,and the final comprehensive analysis indicated that EF-1αwas a relatively stable internal reference gene for P.lactiflora under drought stress.Also,UBQ1 and UBQ2 were the best reference gene combination according to GeNorm analysis.This study will lay a foundation for screening the key genes of P.lactiflora in response to drought stress. | Zhipeng Sheng Yuting Luan Cong Xu Jun Tao Daqiu Zhao | 2023 | Phyton-International Journal of Experimental Botany2023，92，3： | 0 |
| 5 | Selection of Stable Reference Genes for Quantitative Real-Time PCR on Paeonia ostii T.Hong et J.X.Zhang Leaves Exposed to Different Drought Stress Conditions显示文摘The definition of relatively stable expressed internal reference genes is essential in both traditional blotting quantification and as a modern data quantitative strategy.Appropriate internal reference genes can accurately standardize the expression abundance of target genes to avoid serious experimental errors.In this study,the expression profiles of ten candidate genes,ACT1,ACT2,GAPDH,eIF1,eIF2,α-TUB,β-TUB,TBP,RNA Pol II and RP II,were calculated for a suitable reference gene selection in Paeonia ostii T.Hong et J.X.Zhang leaves under various drought stress conditions.Data were processed by the four regularly used evaluation software.A comprehensive analysis revealed that RNA Pol II was the most stable gene and eIF2 was the least stable one.In addition,the geNorm program provided the optimal choice of two reference gene combination,RNA Pol II andβ-TUB,for qRT-PCR normalization in P.ostii subjected to different drought stress levels.Our research provided convenience for gene expression analysis in P.ostii under drought stress and promoted research of effective methods to alleviate P.ostii drought stress in the future. | Yuting Luan Cong Xu Xiaoxiao Wang Daqiu Zhao Jun Tao | 2022 | Phyton-International Journal of Experimental Botany2022，91，5： | 0 |
