3De novo characterization of the root transcriptome of a traditional Chinese medicinal plant Polygonum cuspidatum显示文摘Various active components have been extracted from the root of Polygonum cuspidatum.However,the genetic basis for their activity is virtually unknown.In this study,25600002 short reads (2.3 Gb) of P.cuspidatum root transcriptome were obtained via Illumina HiSeq 2000 sequencing.A total of 86418 unigenes were assembled de novo and annotated.Twelve,18,60 and 54 unigenes were respectively mapped to the mevalonic acid (MVA),methyl-D-erythritol 4-phosphate (MEP),shikimate and resveratrol biosynthesis pathways,suggesting that they are involved in the biosynthesis of pharmaceutically important anthraquinone and resveratrol.Eighteen potential UDP-glycosyltransferase unigenes were identified as the candidates most likely to be involved in the biosynthesis of glycosides of secondary metabolites.Identification of relevant genes could be important in eventually increasing the yields of the medicinally useful constituents of the P.cuspidatum root.From the previously published transcriptome data of 19 non-model plant taxa,1127 shared orthologs were identified and characterized.This information will be very useful for future functional,phylogenetic and evolutionary studies of these plants.HAO DaCheng MA Pei MU Jun CHEN ShiLin XIAO PeiGen PENG Yong HUO Li XU LiJia SUN Chao 2012Science China(Life Sciences)2012,55,5:36
4Rhizospheric microbial communities are driven by Panax ginseng at different growth stages and biocontrol bacteria alleviates replanting mortality显示文摘The cultivation of Panax plants is hindered by replanting problems, which may be caused by plantdriven changes in the soil microbial community. Inoculation with microbial antagonists may efficiently alleviate replanting issues. Through high-throughput sequencing, this study revealed that bacterial diversity decreased,whereas fungal diversity increased, in the rhizosphere soils of adult ginseng plants at the root growth stage under different ages. Few microbial community, such as Luteolibacter, Cytophagaceae, Luteibacter, Sphingomonas,Sphingomonadaceae, and Zygomycota, were observed; the relative abundance of microorganisms, namely,Brevundimonas, Enterobacteriaceae, Pandoraea, Cantharellales, Dendryphion, Fusarium, and Chytridiomycota,increased in the soils of adult ginseng plants compared with those in the soils of 2-year-old seedlings. Bacillus subtilis 50-1, a microbial antagonist against the pathogenic Fusarium oxysporum, was isolated through a dual culture technique. These bacteria acted with a biocontrol efficacy of 67.8%. The ginseng death rate and Fusarium abundance decreased by 63.3% and 46.1%, respectively, after inoculation with B. subtilis 50-1. Data revealed that microecological degradation could result from ginseng-driven changes in rhizospheric microbial communities;these changes are associated with the different ages and developmental stages of ginseng plants. Biocontrol using microbial antagonists alleviated the replanting problem.Linlin Dong Jiang Xu Lianjuan Zhang Ruiyang Cheng Guangfei Wei He Su Juan Yang Jun Qian Ran Xu Shilin Chen 2018Acta Pharmaceutica Sinica B2018,8,2:27
5The Chrysanthemum nankingense Genome Provides Insights into the Evolution and Diversification of Chrysanthemum Flowers and Medicinal Traits显示文摘The Asteraceae (Compositae),a large plant family of approximately 24 000-35 000 species,accounts for^10% of all angiosperm species and contributes a lot to plant diversity.The most representative members of the Asteraceae are the economically important chrysanthemums (Chrysanthemum L.)that diversified through reticulate evolution.Biodiversity is typically created by multiple evolutionary mechanisms such as wholegenome duplication 0NGD)or polyploidization and locally repetitive genome expansion.However,the lack of genomic data from chrysanthemum species has prevented an in-depth analysis of the evolutionary mechanisms involved in their diversification.Here,we used Oxford Nanopore long-read technologyto sequence the diploid Chrysanthemum nankingense genome,which represents one of the progenitor genomes of domesticated chrysanthemums.Our analysis revealed that the evolution of the C.nankingense genome was driven by bursts of repetitive element expansion and WGD events including a recentWGD that distinguishes chrysanthemum from sunflower,which diverged from chrysanthemum approximately 38.8 million years ago.Variations of ornamental and medicinal traits in chrysanthemums are linked to the expansion of candidate gene families by duplication events including paralogous gene duplication.Collectively,our study of the assembled reference genome offers new knowledge and resources to dissect the history and pattern of evolution and diversification of chrysanthemum plants,and also to accelerate their breeding and improvement.Chi Song Yifei Liu Aiping Song Gangqiang Dong Hongbo Zhao Wei Sun Shyam Ramakrishnan Ying Wang Shuaibin Wang Tingzhao Li Yan Niu Jiafu Jiang Bin Dong Ye Xia Sumei Chen Zhigang Hu Fadi Chen Shilin Chen 2018Molecular Plant2018,11,12:24

7Safety issues and new rapid detection methods in traditional Chinese medicinal materials显示文摘The safety of traditional Chinese medicine(TCM) is a major strategic issue that involves human health. With the continuous improvement in disease prevention and treatment, the export of TCM and its related products has increased dramatically in China. However, the frequent safety issues of Chinese medicine have become the ‘bottleneck' impeding the modernization of TCM. It was proved that mycotoxins seriously affect TCM safety; the pesticide residues of TCM are a key problem in TCM international trade; adulterants have also been detected, which is related to market circulation. These three factors have greatly affected TCM safety. In this study, fast, highly effective, economically-feasible and accurate detection methods concerning TCM safety issues were reviewed, especially on the authenticity, mycotoxins and pesticide residues of medicinal materials.Lili Wang Weijun Kong Meihua Yang Jianping Han Shilin Chen 2015Acta Pharmaceutica Sinica B2015,5,1:18
8Complete chloroplast genome sequence of Magnolia grandiflora and comparative analysis with related species显示文摘Magnolia grandiflora is an important medicinal,ornamental and horticultural plant species.The chloroplast(cp) genome of M.grandiflora was sequenced using a 454 sequencing platform and the genome structure was compared with other related species.The complete cp genome of M.grandiflora was 159623 bp in length and contained a pair of inverted repeats(IR) of 26563 bp separated by large and small single copy(LSC,SSC) regions of 87757 and 18740 bp,respectively.A total of 129 genes were successfully annotated,18 of which included introns.The identity,number and GC content of M.grandiflora cp genes were similar to those of other Magnoliaceae species genomes.Analysis revealed 218 simple sequence repeat(SSR) loci,most composed of A or T,contributing to a bias in base composition.The types and abundances of repeat units in Magnoliaceae species were relatively conserved and these loci will be useful for developing M.grandiflora cp genome vectors.In addition,results indicated that the cp genome size in Magnoliaceae species and the position of the IR border were closely related to the length of the ycf1 gene.Phylogenetic analyses based on 66 shared genes from 30 species using maximum parsimony(MP) and maximum likelihood(ML) methods provided strong support for the phylogenetic position of Magnolia.The availability of the complete cp genome sequence of M.grandiflora provides valuable information for breeding of desirable varieties,cp genetic engineering,developing useful molecular markers and phylogenetic analyses in Magnoliaceae.LI XiWen GAO HuanHuan WANG YiTao SONG JingYuan HENRY Robert WU HeZhen HU ZhiGang YAO Hui LUO HongMei LUO Kun PAN HongLin CHEN ShiLin 2013Science China(Life Sciences)2013,56,2:17
9Large-scale analysis of small RNAs derived from traditional Chinese herbs in human tissues显示文摘Plant-derived microRNAs have recently been reported to function in human blood and tissues. Controversy was immediately raised due to possible contamination and the lack of large sample sizes. Here, we report thousands of unique small RNAs derived from traditional Chinese medicine(TCM) herbs found in human blood cells and mouse lung tissues using a large-scale analysis.We extracted small RNAs from decoctions of 10 TCM plants(Ban Zhi Lian, Chai Hu, Chuan Xin Lian, Di Ding Zi Jin, Huang Qin, Jin Yin Hua, Lian Qiao, Pu Gong Ying, Xia Ku Cao, and Yu Xing Cao) and obtained millions of RNA sequences from each herb. We also obtained RNA-Seq data from the blood cells of humans who consumed herbal decoctions and from the lung tissues of mice administered RNAs from herbal decoctions via oral gavage. We identified thousands of unique small RNA sequences in human blood cells and mouse lung tissues. Some of these identified small RNAs from Chuan Xin Lian and Hong Jing Tian could be mapped to the genomes of the herbs, confirming their TCM plant origin. Small RNAs derived from herbs regulate mammalian gene expression in a sequence-specific manner, and thus are a superior novel class of herbal drug components that hold great potential as oral gene-targeted therapeutics, highlighting the important role of herbgenomics in their development.Fengming Huang Jianchao Du Zhu Liang Zhichao Xu Jiantao Xu Yan Zhao Yexuan Lin Song Mei Quan He Jindong Zhu Qiang Liu Yanxu Zhang Yuhao Qin Wei Sun Jingyuan Song Shilin Chen Chengyu Jiang 2019Science China(Life Sciences)2019,62,3:14
10Herbgenomics: A stepping stone for research into herbal medicine显示文摘From the prehistoric era until the publishing of the Compendium of Materia Medica and the first scientific Nobel Prize in the Chinese mainland for Tu's discovery on anti-malarial tablets,each milestone and stepping stone in the developmental history of herbal medicine involved intrepid exploration,bold hypothesis formulation,and cautious verification.After thousands of years of discovery and development,herbal research has entered a new era—the era of herbgenomics.Herbgenomics combines herbal and genomic research,bridging the gap between traditional herbal medicine and cutting-edge omics studies.Therefore,it provides a general picture of the genetic background of traditional herbs,enabling researchers to investigate the mechanisms underlying the prevention and treatment of human diseases from an omics perspective.Haoyu Hu Xiaofeng Shen Baosheng Liao Lu Luo Jiang Xu Shilin Chen 2019Science China(Life Sciences)2019,62,7:13
11Genome-wide characterization and analysis of b HLH transcription factors in Panax ginseng显示文摘Ginseng(Panax ginseng C.A. Meyer) is one of the best-selling herbal medicines, with ginsenosides as its main pharmacologically active constituents. Although extensive chemical and pharmaceutical studies of these compounds have been performed, genome-wide studies of the basic helix-loop-helix(b HLH) transcription factors of ginseng are still limited. The b HLH transcription factor family is one of the largest transcription factor families found in eukaryotic organisms, and these proteins are involved in a myriad of regulatory processes. In our study, 169 bHLH transcription factor genes were identified in the genome of P. ginseng, and phylogenetic analysis indicated that these PGb HLHs could be classified into 24 subfamilies. A total of 21 RNA-seq data sets, including two sequencing libraries for jasmonate(JA)-responsive and 19 reported libraries for organ-specific expression analyses were constructed. Through a combination of gene-specific expression patterns and chemical contents,6 PGbHLH genes from 4 subfamilies were revealed to be potentially involved in the regulation of ginsenoside biosynthesis. These 6 PGbHLHs, which had distinct target genes, were further divided into two groups depending on the absence of MYC-N structure. Our results would provide a foundation for understanding the molecular basis and regulatory mechanisms of bHLH transcription factor action in P.ginseng.Yang Chu Shuiming Xiao He Su Baosheng Liao Jingjing Zhang Jiang Xu Shilin Chen 2018Acta Pharmaceutica Sinica B2018,8,4:13
12Integrated metabolomic and transcriptomic analyses revealed the distribution of saponins in Panax notoginseng显示文摘Panax notoginseng is famous for its important therapeutic effects. Saponins are bioactive compounds found in different parts and developmental stages of P. notoginseng plants. Thus, it is urgently to study saponins distribution in different parts and growth ages of P. notoginseng plants. In this study,potential biomarkers were found, and their chemical characteristic differences were revealed through metabolomic analysis. High-performance liquid chromatography data indicated the higher content of saponins(i.e., Rg1, Re, Rd, and Rb1) in the underground parts than that in the aerial parts. 20(S)-Protopanaxadiol saponins were mainly distributed in the aerial parts. Additionally, the total saponin content in the 3-year-old P. notoginseng plant(188.0 mg/g) was 1.4-fold higher than that in 2-year-old plant(130.5 mg/g). The transcriptomic analysis indicated the tissue-specific transcription expression of genes, namely, PnFPS, PnSS, PnSE1, PnSE2, and PnDS, which encoded critical synthases in saponin biosyntheses. These genes showed similar expression patterns among the parts of P. notoginseng plants.The expression levels of these genes in the flowers and leaves were 5.2 fold higher than that in the roots and fibrils. These results suggested that saponins might be actively synthesized in the aerial parts and transformed to the underground parts. This study provides insights into the chemical and genetic characteristics of P. notoginseng to facilitate the synthesis of its secondary metabolites and a scientific basis for appropriate collection and rational use of this plant.Guangfei Wei Linlin Dong Juan Yang Lianjuan Zhang Jiang Xu Feng Yang Ruiyang Cheng Ran Xu Shilin Chen 2018Acta Pharmaceutica Sinica B2018,8,3:13
13Reconfigurable intelligent surfaces for smart wireless environments:channel estimation,system design and applications in 6G networks显示文摘Reconfigurable intelligent surface(RIS),one of the key enablers for the sixth-generation(6G)mobile communication networks,is considered by designers to smartly reconfigure the wireless propagation environment in a controllable and programmable manner.Specifically,an RIS consists of a large number of low-cost and passive reflective elements(REs)without radio frequency chains.The system gain of RIS wireless systems can be achieved by adjusting the phase shifts and amplitudes of the REs so that the desired signals can be added constructively at the receiver.However,an RIS typically has limited signal processing capability and cannot perform active transmitting/receiving in general,which leads to new challenges in the physical layer design of RIS wireless systems.In this paper,we provide an overview of the RIS-aided wireless systems,including the reflection principle,channel estimation,and system design.In particular,two types of emerging RIS systems are considered:RIS-aided wireless communications(RAWC)and RISbased information transmission(RBIT),where the RIS plays the role of the reflector and the transmitter,respectively.We also envision the potential applications of RIS in 6G networks.Ying-Chang LIANG Jie CHEN Ruizhe LONG Zhen-Qing HE Xianqi LIN Chenlu HUANG Shilin LIU Xuemin(Sherman)SHEN Marco DI RENZO 2021Science China(Information Sciences)2021,64,10:12
14Global Pharmacopoeia Genome Database is an integrated and mineable genomic database for traditional medicines derived from eight international pharmacopoeias显示文摘Genomic data have demonstrated considerable traction in accelerating contemporary studies in traditional medicine. However,the lack of a uniform format and dispersed storage limits the full potential of herb genomic data. In this study, we developed a Global Pharmacopoeia Genome Database(GPGD). The database contains 34,346 records for 903 herb species from eight global pharmacopoeias(Brazilian, Egyptian, European, Indian, Japanese, Korean, the Pharmacopoeia of the People’s Republic of China, and U.S. Pharmacopoeia’s Herbal Medicines Compendium). In particular, the GPGD contains 21,872 DNA barcodes from 867 species, 2,203 organelle genomes from 674 species, 55 whole genomes from 49 species, 534 genomic sequencing datasets from 366 species, and 9,682 transcriptome datasets from 350 species. Among the organelle genomes, 534 genomes from 366 species were newly generated in this study. Whole genomes, organelle genomes, genomic fragments, transcriptomes, and DNA barcodes were uniformly formatted and arranged by species. The GPGD is publicly accessible at http://gffzzf938e9d610ce4c4ahbwx0wcnnfok966n0.ffgz.tsg.suse.edu.cn and serves as an essential resource for species identification, decomposition of biosynthetic pathways, and molecular-assisted breeding analysis. Thus, the database is an invaluable resource for future studies on herbal medicine safety, drug discovery, and the protection and rational use of herbal resources.Baosheng Liao Haoyu Hu Shuiming Xiao Guanru Zhou Wei Sun Yang Chu Xiangxiao Meng Jianhe Wei Han Zhang Jiang Xu Shilin Chen 2022Science China(Life Sciences)2022,65,4:11
15Allele-aware chromosome-level genome assembly of Artemisia annua reveals the correlation between ADS expansion and artemisinin yield显示文摘Artemisia annua is the major natural source of artemisinin,an anti-malarial medicine commonly used worldwide.Here,we present chromosome-level haploid maps for two A.annua strains with different artemisinin contents to explore the relationships between genomic organization and artemisinin production.High-fidelity sequencing,optical mapping,and chromatin conformation capture sequencing were used to assemble the heterogeneous and repetitive genome and resolve the haplotypes of A.annua.Approximately 5o,ooo genes were annotated for each haplotype genome,and a triplication event that occurred approximately 58.12million years ago was examined for the first time in this species.A total of 3,903,467-5,193,414 variants(SNPs,indels,and structural variants)were identified in the 1.5-Gb genome during pairwise comparison between haplotypes,consistent with the high heterozygosity of this species.Genomic analyses revealed a correlation between artemisinin concents and the copy number of amorpha-4,11-dienes ynthasegenes.This correlation was further confirmed by resequencing of 36A.annua samples with varied artemisinin contents.Circular consensus sequencing of transcripts facilitated the detection of paralog expression.Collectively,our study provides chromosome-level allele-aware genome assemblies for two A.annua strains and new insights into the biosynthesis of artemisinin and its regulation,which will contribute to conquering malaria worldwide.Baosheng Liao Xiaofeng Shen Li Xiang Shuai Guo Shiyu Chen Ying Meng Yu Liang Dandan Ding Junqi Bai Dong Zhang Tomasz Czechowski Yi Li Hui Yao Tingyu Mai Caroline Howard Chao Sun Haitao Liu Jiushi Liu Jin Pei Jihai Gao Jigang Wang Xiaohui Qiu Zhihai Huang Hongyi Li Ling Yuan Jianhe Wei lan Graham Jiang Xu Boli Zhang Shilin Chen 2022Molecular Plant2022,15,8:9

19Cloning and analysis of 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate reductase genes HsHDR1 and HsHDR2 in Huperzia serrate显示文摘We cloned and analyzed the two genes of the 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate reductase(HDR) gene family from Huperzia serrate.The two transcripts coding HDR,named Hs HDR1 and Hs HDR2,were discovered in the transcriptome dataset of H.serrate and were cloned by reverse transcription-polymerase chain reaction(RT-PCR).The physicochemical properties,protein domains,protein secondary structure,and 3D structure of the putative Hs HDR1 and Hs HDR2 proteins were analyzed.The full-length c DNA of the Hs HDR1 gene contained 1431 bp encoding a putative protein with 476 amino acids,whereas the Hs HDR2 gene contained 1428 bp encoding a putative protein of 475 amino acids.These two proteins contained the conserved domain of 1-hydroxy-2-methyl-2-(E)-butenyl-4-diphosphate reductase(PF02401),but without the transmembrane region and signal peptide.The most abundant expression of Hs HDR1 and Hs HDR2 was detected in H.serrate roots,followed by the stems and leaves.Our results provide a foundation for exploring the function of Hs HDR1 and Hs HDR2 in terpenoid and sterol biosynthesis in Huperziaceae plants.Haizhou Lv Xin Zhang Baosheng Liao Wanjing Liu Liu He Jingyuan Song Chao Sun Hongmei Luo Shilin Chen 2015Acta Pharmaceutica Sinica B2015,5,6:3
20Compact ultrabroadband light-emitting diodes based on lanthanide-doped lead-free double perovskites显示文摘Impurity doping is an effective approach to tuning the optoelectronic performance of host materials by imparting extrinsic electronic channels.Herein,a family of lanthanide(Ln^(3+))ions was successfully incorporated into a Bi:Cs_(2)AgInCl_(6) lead-free double-perovskite(DP)semiconductor,expanding the spectral range from visible(Vis)to near-infrared(NIR)and improving the photoluminescence quantum yield(PLQY).After multidoping with Nd,Yb,Er and Tm,Bi/Ln:Cs_(2)AgInCl_(6) yielded an ultrabroadband continuous emission spectrum with a full width at half-maximum of~365 nm originating from intrinsic self-trapped exciton recombination and abundant 4f-4f transitions of the Ln^(3+)dopants.Steady-state and transient-state spectra were used to ascertain the energy transfer and emissive processes.To avoid adverse energy interactions between the various Ln^(3+)ions in a single DP host,a heterogeneous architecture was designed to spatially confine different Ln^(3+)dopants via a“DP-in-glass composite”(DiG)structure.This bottom-up strategy endowed the prepared Ln^(3+)-doped DIG with a high PLQY of 40%(nearly three times as high as that of the multidoped DP)and superior long-term stability.Finally,a compact Vis-NIR ultrabroadband(400~2000 nm)light source was easily fabricated by coupling the DiG with a commercial UV LED chip,and this light source has promising applications in nondestructive spectroscopic analyses and multifunctional lighting.Shilin Jin Renfu Li Hai Huang Naizhong Jiang Jidong Lin Shaoxiong Wang Yuanhui Zheng Xueyuan Chen Daqin Chen 2022Light(Science & Applications)2022,11,3:3
