3The Chromosome-Level Reference Genome of Tea Tree Unveils Recent Bursts of Nonautonomous LTR Retrotransposons in Driving Genome Size Evolution显示文摘Dear Editor,The tea tree Camellia sinensis,a member of the genus Camellia in the Theaceae family,includes two major cultivated varieties,C.sinensis var.assamica(CSA\Assam type)and C.sinensis var.sinensis(CSS;Chinese type)(Ming and Bartholomew,2007).Due to the high economic importance of the tea tree,considerable efforts have been made to explore genetic basis of the biosynthesis of natural metabolites that determine health benefits and diverse tea flavors(Shi et al.,2011;Li et al.,2011;Li et al.,2015;Xia et aL,2017;Liu et al.,2019).Qun-Jie Zhang Wei L i Kui Li Hong Nan Cong Shi Yun Zhang Zhang-Yan Dai Yang-Lei Lin Xiao-Lan Yang Yan Tong Dan Zhang Cui Lu Li-Ying Feng Chen-Feng Wang Xiao-Xin Liu Jian-An Huang Wen-Kai Jiang Xing-Hua Wang Xing-Cai Zhang Evan E.Eichler Zhong-Hua Liu and Li-Zhi Gao 2020Molecular Plant2020,13,7:27
4Pilose antler aqueous extract promotes the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells by stimulating the BMP-2/Smad1, 5/Runx2 signaling pathway显示文摘Peptides from Pilose antler aqueous extract(PAAE) have been shown to stimulate the proliferation and differentiation of bone marrow mesenchymal stem cells(BMSCs). However, the underlying molecular mechanisms are not well understood. Here, PAAE was isolated and purified to explore the molecular mechanisms underlying PAAE’s effects on BMSCs as well as its osteoprotective effects in ovariectomized rats. Our results showed that PAAE promoted proliferation and differentiation of BMSCs to become osteoblasts by enhancing ALP activity and increasing extracellular matrix mineralization. The trabecular microarchitecture of ovariectomized rats was also found to be protected by PAAE. Quantitative reverse transcription-polymerase chain reaction(Quantitative RT-PCR) results suggest that PAAE also increased the expression of osteogenic markers including, alkaline phosphatase(ALP), runt-related transcription factor 2(Runx2), osteocalcin(OCN), bone morphogenetic protein-2(BMP-2), and collagen I(COL-I). Immunoblotting results indicated that PAAE upregulated the levels of BMP-2 and Runx2 and was associated with Smad1/5 phosphorylation. PAAE A at the concentration of 200μg·mL^-1 showed the strongest effect on proliferation and osteogenic differentiation of BMSCs after 48 h. Using matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF MS), we identified the molecular weight of PAAE A and found that it is less than 3000 Da and showed several significant peaks. In conclusion, PAAE activates the BMP-2/Smad1, 5/Runx2 pathway to induce osteoblastic differentiation and mineralization in BMSCs and can inhibit OVX-induced bone loss. These mechanisms are likely responsible for its therapeutic effect on postmenopausal osteoporosis.REN Cong GONG Wei LI Feng XIE Ming 2019Chinese Journal of Natural Medicines2019,17,10:25

6Stable carbon and hydrogen isotopes of gases from the large tight gas fields in China显示文摘By the end of the year 2010,a total of 15 large tight gas fields have been found in China,located in the Ordos,Sichuan,and Tarim basins.The annual production and total reserves of these fields in 2010 were 222.5×108and 28657×108m3,respectively,accounting for 23.5%and 37.3%,respectively,of the total annual production and reserves of natural gases in China.They took a major part of all natural gas production and reserves in China.According to the analyses of 81 gas samples,the stable carbon and hydrogen isotopic compositions of tight gases in China have following characteristics:(1)Plots of 13C1-13C2-13C3,13C1-C1/C2+3and 13C1-13C2demonstrate the coal-derived origin of tight gases in China;(2)For the primary alkane gases,both carbon and hydrogen isotopic values increase with increasing molecular mass,i.e.,13C1<13C2<13C3<13C4and2H1<2H2<2H3;(3)The isotopic differences of 13C2-13C1,13C3-13C1,2H2-2H1and 2H3-2H1decrease with increasing Ro(%)and C1/C1–4;(4)There are seven causes for the carbon and hydrogen isotopic reversal,however,the carbon and hydrogen isotopic reversal of tight gases in China is caused mainly by multiple stages of gas charge and accumulation.DAI JinXing NI YunYan HU GuoYi HUANG ShiPeng LIAO FengRong YU Cong GONG DeYu WU Wei 2014Science China Earth Sciences2014,57,1:17
7The estimate of sea ice resources quantity in the Bohai Sea based on NOAA/AVHRR data显示文摘The research on sea ice resources is the academic base of sea ice exploitation in the Bohai Sea. According to the ice-water spectrum differences and the correlation between ice thickness and albedo, this paper comes up with a sea ice thickness inversion model based on the NOAA/AVHRR data. And then a sea ice resources quantity (SIQ) time series of Bohai Sea is established from 1987 to 2009. The results indicate that the average error of inversion sea ice thickness is below 30%. The maximum sea ice resources quantity is about 6 × 10 9 m 3 and the minimum is 1.3 × 10 9 m 3 . And a preliminary analysis has been made on the errors of the estimate of sea ice resources quantity (SIQ).YUAN Shuai GU Wei XU Yingjun WANG Ping HUANG Shuqing LE Zhangyan CONG Jianou 2012Acta Oceanologica Sinica2012,31,1:15
8The Chromosome-Based Rubber Tree Genome Provides New Insights into Spurge Genome Evolution and Rubber Biosynthesis显示文摘The rubber tree,Hevea brasiliensis,produces natural rubber that serves as an essential industrial raw material.Here,we present a high-quality reference genome for a rubber tree cultivar GT1 using single-molecule real-time sequencing(SMRT)and Hi-C technologies to anchor the~1.47-Gb genome assembly into 18 pseudochromosomes.The chromosome-based genome analysis enabled us to establish a model of spurge chromosome evolution,since the common paleopolyploid event occurred before the split of Hevea and Manihot.We show recent and rapid bursts of the three Hevea-specific LTR-retrotransposon families during the last 10 million years,leading to the massive expansion by~65.88%(~970 Mbp)of the whole rubber tree genome since the divergence from Manihot.We identify large-scale expansion of genes associated with whole rubber biosynthesis processes,such as basal metabolic processes,ethylene biosynthesis,and the activation of polysaccharide and glycoprotein lectin,which are important properties for latex production.A map of genomic variation between the cultivated and wild rubber trees was obtained,which contains~15.7 million high-quality single-nucleotide polymorphisms.We identified hundreds of candidate domestication genes with drastically lowered genomic diversity in the cultivated but not wild rubber trees despite a relatively short domestication history of rubber tree,some of which are involved in rubber biosynthesis.This genome assembly represents key resources for future rubber tree research and breeding,providing novel targets for improving plant biotic and abiotic tolerance and rubber production.Jin Liu Cong Shi Cheng-Cheng Shi Wei Li Qun-Jie Zhang Yun Zhang Kui Li Hui-Fang Lu Chao Shi Si-Tao Zhu Zai-Yun Xiao Hong Nan Yao Yue Xun-Ge Zhu Yu Wu Xiao-Ning Hong Guang-Yi Fan Yan Tong Dan Zhang Chang-Li Mao Yun-Long Liu Shi-Jie Hao Wei-Qing Liu Mei-Qi Lv Hai-Bin Zhang Yuan Liu Ge-Ran Hu-tang Jin-Peng Wang Jia-Hao Wang Ying-Huai Sun Shu-Bang Ni Wen-Bin Chen Xing-Cai Zhang Yuan-Nian Jiao Evan E.Eichler Guo-Hua Li Xin Liu Li-Zhi Gao 2020Molecular Plant2020,13,2:15
9Germanium/perovskite heterostructure for high-performance and broadband photodetector from visible to infrared telecommunication band显示文摘A high-performance and broadband heterojunction photodetector has been successfully fabricated.The heterostructure device is based on a uniform and pinhole-free perovskite film constructed on top of a single-crystal germanium layer.The perovskite/germanium photodetector shows enhanced performance and a broad spectrum compared with the single-material-based device.The photon response properties are characterized in detail from the visible to near-infrared spectrum.At an optical fibre communication wavelength of 1550 nm,the heterojunction device exhibits the highest responsivity of 1.4 A/W.The performance is promoted because of an antireflection perovskite coating,the thickness of which is optimized to 150 nm at the telecommunication band.At a visible light wavelength of 680 nm,the device shows outstanding responsivity and detectivity of 228 A/W and 1.6×10^(10) Jones,respectively.These excellent properties arise from the photoconductive gain boost in the heterostructure device.The presented heterojunction photodetector provides a competitive approach for wide-spectrum photodetection from visible to optical communication areas.Based on the distinguished capacity of light detection and harvesting from the visible to near-infrared spectrum,the designed germanium/perovskite heterostructure configuration is believed to provide new building blocks for novel optoelectronic devices.Wei Hu Hui Cong Wei Huang Yu Huang Lijuan Chen Anlian Pan Chunlai Xue 2019Light(Science & Applications)2019,8,1:14
10EXPERIMENTAL AND THEORETICAL STUDY ON THE HIGH-SPEED HORIZONTAL WATER ENTRY BEHAVIORS OF CYLINDRICAL PROJECTILES显示文摘In this article,the horizontal water-entry of flat-nose projectiles of two different lengths at impact velocities of 400 m/s-600 m/s is studied experimentally and theoretically.Based on the solution of the Rayleigh-Besant problem,a set of projectile dynamic equations are derived and a cavity model is built to describe the projectile's water entry dynamics.A parameter in the cavity model is determined by employing the principle of energy conservation.The results indicate that the flat-nose projectiles enjoy a good stability of trajectory,the drag coefficient and the velocity decay coefficient are dependent on the cavitation number,and increase along the penetration distance but with a relatively small variation.The maximum cavity radius decreases monotonically with the penetration distance.Projectiles with the same nose shapes at different initial velocities have a basically consistent cavity dimension before the deep pinching off phenomenon occurs.Good agreements are observed between results obtained by the analytical model and the experimental results.GUO Zi-tao ZHANG Wei WANG Cong 2012Journal of Hydrodynamics2012,24,2:14
11Few-layer Tellurium:one-dimensional-like layered elementary semiconductor with striking physical properties显示文摘Few-layer Tellurium, an elementary semiconductor, succeeds most of striking physical properties that black phosphorus(BP) offers and could be feasibly synthesized by simple solution-based methods. It is comprised of non-covalently bound parallel Te chains, among which covalent-like feature appears.This feature is, we believe, another demonstration of the previously found covalent-like quasi-bonding(CLQB) where wavefunction hybridization does occur. The strength of this inter-chain CLQB is comparable with that of intra-chain covalent bonding, leading to closed stability of several Te allotropes. It also introduces a tunable bandgap varying from nearly direct 0.31 eV(bulk) to indirect 1.17 eV(2L) and four(two) complex, highly anisotropic and layer-dependent hole(electron) pockets in the first Brillouin zone.It also exhibits an extraordinarily high hole mobility(~10~5 cm^2/Vs) and strong optical absorption along the non-covalently bound direction, nearly isotropic and layer-dependent optical properties, large ideal strength over 20%, better environmental stability than BP and unusual crossover of force constants for interlayer shear and breathing modes. All these results manifest that the few-layer Te is an extraordinary-high-mobility, high optical absorption, intrinsic-anisotropy, low-cost-fabrication, tunable bandgap, better environmental stability and nearly direct bandgap semiconductor. This ‘‘one-dimen sion-like' few-layer Te, together with other geometrically similar layered materials, may promote the emergence of a new family of layered materials.Jingsi Qiao Yuhao Pan Feng Yang Cong Wang Yang Chai Wei Ji 2018Science Bulletin2018,63,3:12

13Biosynthesis of Triacylglycerol Molecules with a Tailored PUFA Profile in Industrial Microalgae显示文摘The composition of polyun saturated fatty acids (PUFAs) in triacylglycerols (TAGs) is key to health ben efits and for oil applications, yet the underlying genetic mechanism remains poorly understood. In this study, by in si Iico, ex vivo, and in vivo profili ng of type-2 diacylglycerol acyltransferases (DGAT2s) in Nannochloropsis oceanica we revealed two novel PUFA-preferring enzymes that discriminate individual PUFA species in TAG assembly, with NoDGAT2J for linoleic acid (LA) and NoDGAT2K for eicosapentaenoic acid (EPA). The LA and EPA composition of TAG molecules is mediated in vivo via the functional partitioning between NoDGAT2J and 2K, both of which are localized in the chloroplast envelope. By modulating transcript abundance of the DGAT2s, an N. oceanica strain bank was created, where proportions of LA and EPA in TAG vary by 18.7-fold (between 0.21% and 3.92% dry weight) and 34.7-fold (between 0.09% and 3.12% dry weight), respective!y. These findings lay the foundation for producing designer TAG molecules with tailored health benefits or for biofuel applications in industrial microalgae and higher-plant crops.Yi Xin Chen Shen Yiting She Hong Chen Cong Wang Li Wei Kangsup Yoon Danxiang Han Qiang Hu Jian Xu 2019Molecular Plant2019,12,4:10
14High-performance PVDF-HFP based gel polymer electrolyte with a safe solvent in Li metal polymer battery显示文摘Poly(vinylidenefluoride-co-hexafluoropropylene)(PVDF-HFP)based gel polymer electrolytes are widely studied owing to their electrochemical stability and high dielectric constant.However,most gel polymer electrolytes show unsatisfied safety and interface compatibility due to excessive absorption of volatile and flammable liquid solvents.Herein,by using a safe solvent(N-methyl-2-pyrrolidone)with higher boiling(203℃)and flash points(95℃),we initiatively fabricate a flexible PVDF-HFP based gel polymer electrolyte.The obtained gel polymer electrolyte demonstrates a high ionic conductivity of 7.24×10^−4 S cm−1,an electrochemical window of 5.2 V,and a high lithium transference number of 0.57.As a result,the synthesized polymer electrolyte exhibits a capacity retention of 70%after 500 cycles at 0.5 C,and a discharge capacity of 86 mAh g−1 even at a high current rate of 10 C for LiFePO4 based Li metal batteries.Moreover,a stable Li plating/stripping for more than 500 h is achieved under 0.1 mAh at both room temperature and 70℃.Our results indicate that the PVDF-HFP polymer electrolyte is promising for manufacturing safe and high-performance Li metal polymer batteries.Jing Jie Yulong Liu Lina Cong Bohao Zhang Wei Lu Xinming Zhang Jun Liu Haiming Xie Liqun Sun 2020Journal of Energy Chemistry2020,29,10:10

19Mucinous colorectal adenocarcinoma:clinical pathology and treatment options显示文摘Mucinous colorectal adenocarcinoma is a distinct subtype of colorectal cancer(CRC)characterized by the pres-ence of abundant extracellular mucin which accounts for at least 50%of the tumor volume.Mucinous colorectal adenocarcinoma is found in 10%-20%of CRC patients and occurs more commonly in female and younger patients.Moreover,mucinous colorectal adenocarcinoma is more frequently located in the proximal colon and diagnosed at an advanced stage.Based on its molecular context,mucinous colorectal adenocarcinoma is associated with the over-expression of mucin 2(MUC2)and mucin 5AC(MUC5AC)proteins.At the same time,it shows higher mutation rates in the fundamental genes of the RAS/MAPK and PI3K/Akt/mTOR pathways.Mucinous colorectal adenocarcinoma also shows higher rates of microsatellite instability(MSI)than non-mucinous colorectal adenocarcinoma which might correlate it with Lynch syndrome and the CpG island methylator phenotype.The prognosis of mucinous colorectal adenocarcinoma as to non-mucinous colorectal adenocarcinoma is debatable.Further,the impaired responses of mucinous colorectal adenocarcinoma to palliative or adjuvant chemotherapy warrant more studies to be performed for a specialized treatment for these patients.In this review,we discuss the molecular background and histopathol-ogy of mucinous colorectal adenocarcinoma,and provide an update on its prognosis and therapeutics from recent literatures.Cong Luo Shuyi Cen Guojun Ding Wei Wu 2019Cancer Communications2019,39,1:8
