| 2 | Genetic basis of high aroma and stress toleranee in the oolong tea cultivar genome显示文摘Tea plants(Camellia sinensis)are commercially cultivated in>60 countries,and their fresh leaves are processed into tea,which is the most widely consumed beverage in the world.Although several chromosome-level tea plant genomes have been published,they collapsed the two haplotypes and ignored a large number of allelic variations that may underlie important biological functions in this species.Here,we present a phased chromosome-scale assembly for an elite oolong tea cultivar,'Huangdan',that is well known for its high levels of aroma.Based on the two sets of haplotype genome data,we identi fi ed numerous genetic variations and a substantial proportion of allelic imbalance related to important traits,including aroma-and stress-related alleles.Comparative genomics revealed extensive structural variations as well as expansion of some gene families,such as terpene synthases(TPSs),that likely contribute to the high-aroma characteristics of the backbone parent,underlying the molecular basis for the biosynthesis of aroma-related chemicals in oolong tea.Our results uncovered the genetic basis of special features of this oolong tea cultivar,providing fundamental genomic resources to study evolution and domestication for the economically important tea crop. | Pengjie Wang Jiaxin Yu Shan Jin Shuai Chen Chuan Yue Wenling Wang Shuilian Gao Hongli Cao Yucheng Zheng Mengya Gu Xuejin Chen Yun Sun Yuqiong Guo Jiangfan Yang Xingtan Zhang Naixing Ye | 2021 | Horticulture Research2021，8，1： | 4 |
| 3 | Identification of PAL genes related to anthocyanin synthesis in tea plants and its correlation with anthocyanin content显示文摘The phenylalanine ammonia-lyase(PAL)gene family in tea plants(Camellia sinensis L.)encodes the enzyme that catalyzes the first reaction of the phenylpropane metabolic pathway.The present study aimed to characterize the PAL genes in tea plants,and get better insights on the CsPALs in anthocyanins accumulation.Seven CsPAL genes were identified and characterized in tea plants by bioinformatics analysis.Systematic analysis of CsPALs was conducted for its phylogenetic relationship,gene structure,chromosomal location,and protein conserved motifs based on tea plant genome.The cis-elements of CsPALs were responsive to light,abiotic stress,hormone,and MYB-binding site.Furthermore,tissuespecific expression analysis showed that CsPAL4 was expressed preferentially in young leaves and buds.Correlation analysis was performed in purple-leaf tea with anthocyanin components,and it was suggested that CsPAL4 was closely related with different anthocyanin accumulated,especially with cyanidin 3-O-galactoside,cyanidin 3-O-glucoside,and delphinidin 3-O-glucoside.Additionally,the putative upstream regulation factors CsMYBs(CsMYB59,CsARR1,CsSRM1,CsMYB101,and CsMYB52)and CsbHLHs(CsbHLH104,CsbHLH3,CsbIM1,CsTCP14,and CsPIF4)could bind to the promoter of CsPALs,thereby activating its transcription.This study provides a theoretical basis for further research to elucidate the functions of the CsPAL genes. | Xuejin Chen Pengjie Wang Mengya Gu Binghao Hou Churan Zhang Yucheng Zheng Yun Sun Shan Jin Naixing Ye | 2022 | Horticultural Plant Journal2022，8，3： | 4 |
| 4 | Stereoselective C(sp^3)-C(sp^2) Negishi coupling of (2-amido-1-phenylpropyl)zinc compounds through the steric control of β-amido group显示文摘A controllable diastereoselective C(sp2)-C(sp3) Negishi coupling reaction of secondary benzylic zinc reagents with aryl bromides has been demonstrated for the first time, forming medicinally important 1-arylphenylethylamines. In the presence of Pd(OAc) 2 and S-phos, open-chain (2-amido-1-phenylethyl)zinc reagents bearing a -NHAc or NHCHO group underwent cross-coupling reaction to give syn 1-arylphenylethylamine as the major products, whereas the zinc reagents bearing a sterically hindered-NHCOC(CH3)2 OTBS group specifically yielded anti 1-arylphenylethylamines. | TANG Shi LI ShuHua ZHOU Dong ZENG HuiQiong WANG NaiXing | 2013 | Science China Chemistry2013，56，9： | 3 |
| 5 | Geometry Effects on Aerodynamics Performance of a Low Aspect Ratio Turbine Nozzle显示文摘This paper describes the influence of some geometric parameters on aerodynamics performance of a low-aspect-ratio turbine blading designed by a novel method developed at the Institute of Engineering Thermophysics, Chinese Academy of Sciences. This is a part of the study on aerodynamics optimization of turbomachinery. It follows the development of the basic ideas in the turbomachinery aerodynamics research project at the institute. The present paper concentrates mainly on the effects of geometry, such as stagger angle, leading and trailing edge thickness, maximum thickness and its location on adiabatic efficiency, total pressure ratio and mass flow rate. The study was performed and assessed for a low-aspect ratio turbine nozzle using 3D steady Reynolds-averaged N.S. solver. Using the knowledge of the flow physics analysis an optimized turbine nozzle was obtained. | Naixing Chen Hongwu Zhang Yanji Xu Weiguang Huang | 2004 | Journal of Thermal Science2004，13，4： | 3 |

| 7 | Chromatin accessibility and translational Iandscapes of tea plants under chilling stress显示文摘Plants have evolved regulatory mechanisms at multiple levels to regulate gene expression in order to improve their cold adaptability.However,limited information is available regarding the stress response at the chromatin and translational levels.Here,we characterize the chromatin accessibility,transcriptional,and translational landscapes of tea plants in vivo under chilling stress for the first time.Chilling stress signi ficantly affected both the transcription and translation levels as well as the translation efficiency of tea plants.A total of 3010 genes that underwent rapid and independent translation under chilling stress were observed,and they were signi ficantly enriched in the photosynthesis-antenna protein and phenylpropanoid biosynthesis pathways.A set of genes that were signi ficantly responsive to cold at the transcription and translation levels,including four(+)-neomenthol dehydrogenases(MNDs)and two(E)-nerolidol synthases(NESs)arranged in tandem on the chromosomes,were also found.We detected potential upstream open reading frames(uORFs)on 3082 genes and found that tea plants may inhibit the overall expression of genes by enhancing the translation of uORFs under chilling stress.In addition,we identi fied distal transposase hypersensitive sites(THSs)and proximal THSs and constructed a transcriptional regulatory network for tea plants under chilling stress.We also identi fied 13 high-con fidence transcription factors(TFs)that may play a crucial role in cold regulation.These results provide valuable information regarding the potential transcriptional regulatory network in plants and help to clarify how plants exhibit flexible responses to chilling stress. | Pengjie Wang Shan Jin Xuejin Chen Liangyu Wu Yucheng Zheng Chuan Yue Yongchun Guo Xingtan Zhang Jiangfan Yang Naixing Ye | 2021 | Horticulture Research2021，8，1： | 2 |

| 10 | The influence of macronitrogen (NO_3^- and NH_4^+) addition with U lva pertusa on dissolved inorganic carbon system显示文摘The influence of macronitrogen (NO - 3 and NH + 4 ) addition with Ulva pertusa on dissolved inorganic carbon system in seawater was studied. The results indicate that p(CO 2 ) and HCO 3 concentration decrease significantly, while pH and CO 2- 3 concentration increase significantly. When the concentration of NO 3 was less than 71 μmol/dm 3 or NH + 4 was less than 49.7 μmol/dm 3 , dissolved inorganic carbon (DIC) absorption rates by Ulva pertusa generally increased with the increasing of nitrogen concentration. The DIC decreased 151 μmol/dm 3 with the addition of 71 μmol/dm 3 NO 3 and decreased 232 μmol/dm 3 with the addition of 49.7 μmol/dm 3 NH + 4 after the experiment compared with DIC measured without nitrogen addition. A significant negative-correlation was found between c(DIC) and growth rate (μ) of Ulva pertusa (r = -0.91, P <0.000 1, n=11). NH + 4 had more influence on the species of inorganic carbon system than NO 3 . | ZHANG Naixing SONG Jinming CAO Conghua REN Rongzhu WU Fengcong ZHANG Shaoping SUN Xu | 2012 | Acta Oceanologica Sinica2012，31，1： | 1 |

| 16 | A Study of 3D Aerodynamic Design for a Transonic Compressor Blading Optimized by the Locations of Aerofoil Maximum Thickness and Maximum Camber显示文摘A design procedure for improving the efficiency of a transonic compressor blading was proposed based on a rapid generation method for three-dimensional blade configuration and computational meshes, a three-dimensional Navier-Stokes solver and an optimization approach. The objective of the present paper is to design a transonic compressor blading optimized only by selection of the locations of maximum camber and maximum thickness for the airfoils at different span heights and to study how do these two design parameters affect the blade performance. The blading configuration and the computational meshes can be obtained very rapidly for any given combination of maximum camber and maximum thickness. The computational grid system generated is used fox the Navier-Stokes solution to predict adiabatic efficiency, total pressure ratio and flow rate. As a main result of the optimization, adiabatic efficiency was successfully improved. | Naixing Chen Hongwu Zhang Yanji Xu Weiguang HuangInstitute of Engineering Thermophysics, Chinese Academy of Sciences, P.O.
