| 2 | Control of Bird Feeding Behavior by Tannin1 through Modulating the Biosynthesis of Polyphenols and Fatty Acid-Derived Volatiles in Sorghum显示文摘Bird predation during seed maturation causes great loss to agricultural production.In this study,through GWAS analysis of a large-scale sorghum germplasm diversity panel,we identified that Tannin1,which encodes a WD40 protein functioning in the WD40/MYB/bHLH complex,controls bird feeding behavior in sorghum.Metabolic profiling analysis showed that a group of sorghum accessions preferred by birds contain mutated tan1-a/b alleles and accumulate significantly lower levels of anthocyanins and condensed tannin compounds.In contrast,a variety of aromatic and fatty acid-derived volatiles accumulate at significantly higher levels in these bird-preference accessions.We subsequently conducted both sparrow feeding and sparrow volatile attractant assays,which confirmed,respectively,the antifeedant and attractant functions of these differentially accumulated metabolites.In addition,the connection between the biosynthesis pathway of anthocyanin and proanthocyanidin and the pathway of fatty acid–derived volatile biosynthesis was demonstrated by discovering that Tannin1 complex modulates fatty acid biosynthesis by regulating the expression of SbGL2 in sorghum,thus affecting the accumulation of fatty acid-derived volatiles.Taken together,our study identified Tannin1 as the gene underlying the major locus controlling bird feeding behavior in sorghum,illustrating an example of the identification of an ecologically impactful molecular mechanism from field observation and providing significant insights into the chemistry of bird–plant ecological interactions. | Peng Xie Jiayang Shi Sanyuan Tang Chengxuan Chen Aimal Khan Fengxia Zhang Ying Xiong Chao Li Wei He Guodong Wang Fumin Lei Yaorong Wu Qi Xie | 2019 | Molecular Plant2019，12，10： | 8 |
| 3 | Estrogen and insulin synergistically promote endometrial cancer progression via crosstalk between their receptor signaling pathways显示文摘Objective: Despite evidence that estrogens and insulin are involved in the development and progression of many cancers, their synergistic role in endometrial carcinoma(EC) has not been analyzed yet.Methods: Here, we investigated how estrogens act synergistically with insulin to promote EC progression. Cell growth in vitro and in vivo, effects of estradiol and insulin on apoptosis and cell cycle distribution, and expression and activation of estrogen receptor(ER), insulin receptor(InsR), and key proteins in the PI3K and MAPK pathways were examined after combined stimulation with estradiol and insulin.Results: Compared to EC cells treated with estradiol or insulin alone, those treated with both estradiol and insulin exhibited stronger stimulation. Estradiol significantly induced phosphorylation of InsR-β and IRS-1, whereas insulin significantly induced phosphorylation of ER-α. In addition, treatment with both insulin and estradiol together significantly increased the expression and phosphorylation of Akt, MAPK, and ERK. Notably, InsR-β inhibition had a limited effect on estradiol-dependent proliferation,cell cycle, and apoptosis, whereas ER-α inhibition had a limited insulin-dependent effect, in EC cell lines. Insulin and estradiol individually and synergistically promoted EC xenograft growth in mice.Conclusions: Estrogen and insulin play synergistic roles in EC carcinogenesis and progression by activating InsR-β and ER-α,promoting a crosstalk between them, and thereby resulting in the activation of downstream PI3K/Akt and MAPK/ERK signaling pathways. | Wenyan Tian Fei Teng Jinping Gao Chao Gao Guoyan Liu Yanfang Zhang Shizhu Yu Wei Zhang Yingmei Wang Fengxia Xue | 2019 | Cancer Biology & Medicine2019，16，1： | 6 |
| 4 | Overaccumulation of glycine betaine makes the function of the thylakoid membrane better in wheat under salt stress显示文摘Wheat(Triticum aestivum L.) lines T1, T4, and T6 were genetically modified to increase glycine betaine(GB) synthesis by introduction of the BADH(betaine aldehyde dehydrogenase, BADH)gene from mountain spinach(Atriplex hortensis L.). These transgenic lines and WT of wheat(T. aestivum L.) were used to study the effect of increased GB synthesis on wheat tolerance to salt stress. Salt stress due to 200 mmol L-1Na Cl impaired the photosynthesis of the four wheat lines, as indicated by declines in net photosynthetic rate(Pn), stomatal conductance(Gs),maximum photochemical efficiency of PSII(Fv/Fm), and actual photochemical efficiency of PSII(ФPSII) and an increase in intercellular CO2concentration(Ci). In comparison with WT, the effect of salinity on the three transgenic lines was mild. Salt stress caused disadvantageous changes in lipids and their fatty acid compositions in the thylakoid membrane of the transgenic lines and WT. Under salt stress, the three transgenic lines showed slightly higher chlorophyll and carotenoid contents and higher Hill reaction activities and Ca2+-ATPase activity than WT. All the results suggest that overaccumulation of GB resulting from introduction of the BADH gene can enhance the salt tolerance of transgenic plants, especially in the protection of the components and function of thylakoid membranes, thereby making photosynthesis better. Changes in lipids and fatty acid compositions in the thylakoid membrane may be involved in the increased salt stress tolerance of the transgenic lines. | Fengxia Tian Wenqiang Wang Chao Liang Xin Wang Guiping Wang Wei Wang | 2017 | The Crop Journal2017，5，1： | 4 |
| 5 | miR-506: a regulator of chemo-sensitivity through suppression of the RAD51-homologous recombination axis显示文摘Ovarian carcinoma is the most lethal gynecologic malignancy. Resistance to platinum is considered the major problem afecting prognosis. Our recent study established that micro RNA-506(mi R-506) expression was closely associated with progression-free survival and overall survival in two independent patient cohorts totaling 598 epithelial ovarian cancer cases. Further functional study demonstrated that mi R-506 could augment the response to cisplatin and olaparib through targeting RAD51 and suppressing homologous recombination in a panel of ovarian cancer cell lines. Systemic delivery of mi R-506 in an orthotopic ovarian cancer mouse model signiicantly augmented the cisplatin response, thus recapitulating the clinical observation. Therefore, mi R-506 plays a functionally important role in homologous recombination and has important therapeutic value for sensitizing cancer cells to chemotherapy, especially in chemo-resistant patients with attenuated expression of mi R-506. | Guoyan Liu Fengxia Xue Wei Zhang | 2015 | Chinese Journal of Cancer2015，34，11： | 4 |

The new IFV project combines the advantage of running the shell and tube heat exchangers at high pressure with the advantage of compact space of heat exchangers. Thermal analysis on the two processes of forced convection and vaporization type heat transfer in the spiral wound tubes and vapor condensation /re-boiling type of heat transfer via intermediate fluid in shell side shows the feasibility of this promising technology. | Liu Fengxia Dai Yuqiang Wei Wei Zou Jiupeng Zhu Che Dong Chao Hu Dapeng | 2013 | China Petroleum Processing & Petrochemical Technology2013，15，1： | 2 |

| 8 | Transparent flexible thin-film p-n junction thermoelectric module显示文摘Transparent and flexible thermoelectrics has been highly sought after for future wearable devices.However,the main stumbling block to prevent its widespread adoption is the lack of p-type transparent thermoelectrics and the stringent criteria of electrical and thermal properties matching appropriately between p-legs and n-legs.This work demonstrates the fabrication of p-type PEDOT:PSS films whose optical properties,electrical conductivity,thermal conductivity,and Seebeck coefficient were engineered to perfectly match the n-type indium tin oxide(ITO)counterparts.The dense p-type PEDOT:PSS and n-type ITO thin films show a thermoelectric figure of merit of zT=0.30 and 0.29 at 450 K,and a thermal conductivity of 0.22 and 0.32 W m^(−1) K^(−1),respectively.A flexible thermoelectric generator(TEG)module with a high transmittance of>81%in the visible wavelength range of 400-800 nm is fabricated using 10 pairs of p-type PEDOT:PSS and n-type ITO thin film legs.An ultra-high power density of 22.2 W m^(−2) at a temperature gradient of 80 K was observed,which is the highest power density reported for organic/hybrid-based flexible TEGs so far.Our transparent flexible thin-film p-n junction thermoelectric module with exceptionally high power generation may take a tremendous step forward towards multi-functional wearable devices. | Xizu Wang Ady Suwardi Siew Lay Lim Fengxia Wei Jianwei Xu | 2020 | npj Flexible Electronics2020，4，1： | 2 |

| 10 | Evaluation of abundant hydrocarbon-generation depressions in the deepwater area of Qiongdongnan Basin,South China Sea显示文摘It has been confirmed that the key source rocks of Qiongdongnan Basin are associated with the Yacheng Formation, which was deposited in a transitional marine-continental environment. Because the distribution and evolution patterns of the source rocks in the major depressions are different, it is important to determine the most abundant hydrocarbon-generation depressions in terms of exploration effectiveness. Based on an analysis of organic matter characteristics of the source rocks, in combination with drilling data and seismic data, this paper establishes a model to evaluate the hydrocarbon-generation depressions in the deepwater area of Qiongdongnan Basin. First of all, by using the method of seismic-facies model analysis, the distribution of sedimentary facies was determined. Then, the sedimentary facies were correlated with the organic facies, and the distribution of organic facies was predicted. Meanwhile, the thickness of source rocks for all the depressions was calculated on the basis of a quantitative analysis of seismic velocity and lithology. The relationship between mudstone porosity and vitrinite reflectance(Ro) was used to predict the maturity of source rocks. Second, using the parameters such as thickness and maturity of source rocks, the quantity and intensity of gas generation for Yacheng and Lingshui Formations were calculated. Finally, in combination with the identified hydrocarbon resources, the quantity and intensity of gas generation were used as a guide to establish an evaluation standard for hydrocarbon-generation depressions, which was optimized for the main depressions in the Central Depression Belt. It is proposed that Lingshui, Ledong, Baodao and Changchang Depressions are the most abundant hydrocarbon depressions, whilst Songnan and Beijiao Depressions are rich hydrocarbon depressions. Such an evaluation procedure is beneficial to the next stage of exploration in the deep-water area of Qiongdongnan Basin. | LIU Zhen SUN Zhipeng WANG Zisong ZHANG Wei LI Tingan HE Weijun LI Fengxia CAO Shang LIU Jingjing LIN Lu | 2016 | Acta Oceanologica Sinica2016，35，2： | 1 |

| 12 | Enhanced thermoelectric performance and atomic-resolution interfacial structures in BiSbTe thermo-electro-magnetic nanocomposites incorporating magnetocaloric LaFeSi nanoparticles显示文摘Incorporating magnetic nanoparticles in thermoelectric(TE)materials introduce magnetic interfaces with additional electron and phonon scattering mechanism for high TE performance.However,the influence of heterogeneous interfaces between magnetic nanoparticles and TE matrix on electronic and thermal transport remains elusive in the thermo-electric-magnetic nanocomposites.Here,using p-type TE material Bi_(0.3)Sb_(1.7)Te_(3)(BST)as matrix and magnetocaloric(MC)material La(Fe_(0.92)Co_(0.08))_(11.9)Si_(1.1)(LFS)nanoparticles as a second phase,TE/MC nanocomposites xLFS/BST(x=0.1%,0.2%,0.3% and 0.4%)were synthesized using spark plasma sintering method.The atomic-resolution interfacial structures demonstrate that Te vacancies originating from LFS-BST interfacial reaction decreases the hole concentration of the LFS/BST nanocomposites and enhances the Seebeck coefficient.The LFS/BST nanocomposites exhibit lower thermal conductivity due to enhanced phonon scattering by interfaces and defects.All the nanocomposites have higher ZT than BST matrix,with 0.2% LFS/BST nanocomposite achieving highest ZT=1.11 at 380 K.At working current 1.4 A,the device fabricated using 0.2% LFS/BST nanocomposite achieves maximal cooling temperature 4.9 K,which is 58% higher than the matrix.Moreover,the MC properties are retained in all the nanocomposites,which make them a promising candidate to achieve high TE performance and dual TE/MC properties for future applications. | Lin Xing Wenjun Cui Xiahan Sang Fengxia Hu Ping Wei Wanting Zhu Xiaolei Nie Qingjie Zhang Wenyu Zhao | 2021 | Journal of Materiomics2021，7，5： | 1 |
| 13 | Transformation of microstructure and phase of disodium guanosine 5′-monophosphate: Thermodynamic perspectives显示文摘Microstructure and phase transformation of disodium guanosine 5′-monophosphate(5′-GMPNa_2) are extremely important for controlling the process and understanding the mechanism of crystallization. In this work, the thermodynamic properties of polymorphous 5′-GMPNa_2 especially the solubility were studied, the solubility results show that 5′-GMPNa_2 is more soluble in ethanol–water(E–W) than in isopropanol–water(I–W). The amorphous form of 5′-GMPNa_2 is more soluble than the crystalline form at the same mole fraction and temperature. Meanwhile, the crystalline forms and morphologies of the residual solids were characterized by PXRD and SEM. The results indicate that solid forms of 5′-GMPNa_2 transformed spontaneously from amorphous to crystalline when the ethanol proportion is ≥20%. In addition, increasing the pH facilitates the dissolution of 5′-GMPNa_2 and helps to maintain the crystalline form. The associated Gibbs free energy values were calculated to verify the trend of transformation from amorphous to crystalline 5′-GMPNa_2. These results should help to guide the industrial crystallization process and to obtain the crystalline form of 5′-GMPNa_2. | Qiao Chen Fengxia Zou Pengpeng Yang Jingwei Zhou Jinglan Wu Wei Zhuang Hanjie Ying | 2018 | Chinese Journal of Chemical Engineering2018，26，10： | 1 |

| 18 | In vivo and in vitro development of Tibetan antelope(Pantholops hodgsonii)interspecific cloned embryos显示文摘The Tibetan antelope is endemic to the Tibetan Plateau,China,and is now considered an endangered species.As a possible rescue strategy,the development of embryos constructed by interspecies somatic cell nuclear transfer(iSCNT)was examined.Tibetan antelope fibroblast cells were transferred into enucleated bovine,ovine and caprine oocytes.These cloned embryos were then cultured in vitro or in the oviducts of intermediate animals.Less than 0.5%of the reconstructed antelope-bovine embryos cultured in vitro developed to the blastocyst stage.However,when the cloned antelope-bovine embryos were transferred to caprine oviducts,about 1.6%of the embryos developed to the blastocyst stage.In contrast,only 0.7%of the antelope-ovine embryos developed to the morula stage and none developed to blastocysts in ovine oviducts.The treatment of donor cells and bovine oocytes with trichostatin A did not improve the embryo development even when cultured in the oviducts of ovine and caprine.When the antelope-bovine embryos,constructed from oocytes treated with roscovitine or trichostatin A,were cultured in rabbit oviducts 2.3%and 14.3%developed to blastocysts,respectively.It is concluded that although some success was achieved with the protocols used,interspecies cloning of Tibetan antelope presents difficulties still to be overcome.The mechanisms resulting in the low embryo development need investigation and progress might require a deeper understanding of cellular reprogramming. | Guanghua SU Lei CHENG Yu GAO Kun LIU Zhuying WEI Chunling BAI Fengxia YIN Li GAO Guangpeng LI Shorgan BOU | 2014 | Frontiers of Agricultural Science and Engineering2014，1，1： | 1 |
| 19 | The genetic control of glabrous glume during African rice domestication显示文摘African cultivated rice,Oryza glaberrima,is characterized by its glabrous glumes.During domestication,the pubescent glumes of its wild ancestor,Oryza barthii,lost their trichomes,and in this study,we show that glabrous glume 5(GLAG5),a WUSCHEL-like homeobox transcription factor gene on chromosome 5,is required for trichome development.DNA methylation associated with an hATtransposable element inserted in the promoter region of GLAG5 is found to reduce its expression,leading to the formation of glabrous glumes and leaves in African cultivated rice.Among 82 African cultivated rice varieties investigated in this study,59(approximately 71%)lines exhibit glabrous glumes and harbor the hAT transposon;however,the other 23 varieties(approximately 29%),which exhibit pubescent glumes,lack the hAT transposon,indicating that glag5 had undergone strong artificial selection.Theπ;/π;ratios also show the hAT transposon insertions influence the genetic diversity of an approximately 150-kb interval encompassing the GLAG5 locus.The identification of the GLAG5 gene provides new insights into the domestication of cultivated rice in Africa.We speculate that the selection of varieties with mutations in their promoter regions is an important aspect of crop domestication. | Leqin Chang Min Hu Jing Ning Wei He Jiayu Gao Marie-Noelle Ndjiondjop Yongcai Fu Fengxia Liu Hongying Sun Ping Gu Chuanqing Sun Zuofeng Zhu | 2022 | Journal of Genetics and Genomics2022，49，5： | 1 |
