1Role of ethylene signaling in the production of rice volatiles induced by the rice brown planthopper Nilaparvata lugens显示文摘Ethylene signaling pathway plays an important role in induced plant direct defense against herbivores and pathogens; however, up to now, only few researches have focused on its role in induced plant indirect defense, i.e. the release of herbi- vore-induced volatiles, and the results are variable. Using a model system consisting of rice plants, the rice brown planthopper Nilaparvata lugens and its egg parasitoid Anagrus nilaparvatae, we examined the role of ethylene signaling in the production of rice volatiles induced by N. lugens by measuring both the timing of herbivore-induced ethylene levels and the relationships between ethylene, rice volatiles and attraction of the parasitoid. N. lugens infestation sig- nificantly enhanced the release of ethylene during 2―24 h after infestation. Plants treated with eth- ephon, a compound that breaks down to release ethylene at cytoplasmic pH, released volatiles profiles similar to those released by N. lugens-infested plants, and both of them showed an equal attraction of the parasitoid. Moreover, pretreatment with 1-MCP, an inhibitor of ethylene perception, reduced the release of most of rice volatiles whose amount was enhanced by N. lugens infestation and decreased the attrac- tiveness to the parasitoid. These results demonstrate that ethylene signaling is required for the production of rice volatiles induced by N. lugens.LU Yujie WANG Xia LOU Yonggen CHENG Jiaan 2006Chinese Science Bulletin2006,51,20:12
2Differential gene expression profiling in the developed ovaries between the parthenogenetic and bisexual female rice water weevils,Lissorhoptrus oryzophilus Kuschel(Coleoptera:Curculionidae)显示文摘The rice water weevil,Lissorhoptrus oryzophilus Kuschel(Coleoptera:Curculionidae),reproduces by sex in the Southeastern United States,but reproduces by parthenogenesis in California and other invaded regions in Asia and Europe.The objective of this study was to create a parthenogenetic gene expression profile of the rice water weevil in order to gain a better insight into the molecular mechanisms of parthenogenesis in the weevil.Suppression subtractive hybridization(SSH) technique was employed for profiling differential gene expression in the developed ovary between the parthenogenetic and bisexual female rice water weevils.A total of 70 contigs were obtained,and the BLASTX search identified putatively 28 genes with differential functions.According to the cytological process of parthenogenesis,the tubulin alpha-1 chain and signal transduction genes etc.were selected for real time quantitative RT-PCR analyses,and their possible functions related to the molecular mechanism of parthenogenesis were discussed.The tubulin alpha-1 chain and some signal transduction genes may be related to the molecular mechanisms of parthenogenesis of the rice water weevil.YANG Pu ZHOU WenWu ZHANG Qin CHENG JiaAn ZHU ZengRongx WAY MO 2009Chinese Science Bulletin2009,54,20:8
3β-Glucosidase treatment and infestation by the rice brown planthopper Nilaparvata lugens elicit similar signaling pathways in rice plants显示文摘β-Glucosidase has been reported to induce the production of herbivore-induced plant volatiles. How-ever, how it works remains unclear. Here, we investigated the levels of salicylic acid (SA), jasmonic acid (JA), ethylene, and H2O2, all of which are known signaling molecules that play important roles in in-duced plant defense in rice plants treated with β-glucosidase, and compared these to levels in plants infested by the rice brown planthopper Nilaparvata lugens (Stl). Results showed that wounding and treatment by β-glucosidase increased the levels of SA, ethylene, and H2O2, but not JA, in all plants compared to control plants. The signaling pathways activated by β-glucosidase treatment are similar to those activated by an infestation by N. lugens, although the magnitude and timing of the signals elicited by the two treatments are different. This may explain why both treatments have similar volatile profiles and are equally attractive to the parasitoid Anagrus nilaparvatae Pang et Wang.WANG Xia ZHOU GuoXin XIANG CaiYu DU MengHao CHENG JiaAn LIU ShuSheng LOU YongGen 2008Chinese Science Bulletin2008,53,1:5
4Salicylic acid and ethylene signaling pathways are involved in production of rice trypsin proteinase inhibitors induced by the leaf folder Cnaphalocrocis medinalis(Guenée)显示文摘The roles of signaling pathways in the production of trypsin proteinase inhibitors(TrypPIs)in rice infested by the leaf folder(LF) Cnaphalocrocis medinalis were studied.Infestation by LF increased TrypPI levels in the leaves of rice plants at the tillering,booting and flowering stages but decreased TrypPI levels at the ripening stage;TrypPI levels in rice stems did not increase at any developmental stage.Infestation by LF at the tillering stage systemically increased TrypPI levels in leaves but not in stems;it also enhanced salicylic acid(SA)levels in leaves and stems,and the ethylene level released from plants.However,LF infestation did not increase JA concentrations.Exogenous application of SA or ethylene enhanced TrypPI levels in the leaves and stems of plants at the tillering stage,whereas treatment with both SA and ethylene induced lower levels of TrypPIs than treatment with SA or ethylene alone,suggesting an antagonistic effect of SA and ethylene on TrypPIs induction.The results suggest that both SA and ethylene signaling pathways are involved in the production of TrypPIs in rice induced by LF;moreover,the antagonistic effect of SA and ethylene may explain the changes in TrypPI levels seen at different plant developmental stages and in different organs.WANG Xia HU LiuCheng ZHOU GuoXin CHENG JiaAn LOU YongGen 2011Chinese Science Bulletin2011,56,22:5
5Characterization and validation of somatic mutation spectrum to reveal heterogeneity in gastric cancer by single cell sequencing显示文摘Gastric cancer(GC) is a highly heterogeneous disease with multiple cellular types and poor prognosis.However, the cellular evolution and molecular basis of GC at the individual intra-tumor level has not been well demonstrated. We performed single-cell whole exome sequencing to detect somatic singlenucleotide variants(SNVs) and significantly mutated genes(SMGs) among 34 tumor cells and 9 normal cells from a patient with GC. The Complete Prediction for Protein Conformation(CPPC) approach directly predicting the folding conformation of the protein 3D structure with Protein Folding Shape Code, combined with functional experiments were used to confirm the characterization of mutated SMGs in GC cells. We identified 201 somatic SNVs, including 117 non-synonymous mutations in GC cells. Further analysis identified 24 significant mutated genes(SMGs) in single cells, for which a single amino acid change might affect protein conformation. Among them, two genes(CDC27 and FLG) that were mutated only in single cells but not in the corresponding tumor tissue, were recurrently present in another GC tissue cohort, and may play a potential role to promote carcinogenesis, as confirmed by functional characterization. Our findings showed a mutational landscape of GC at intra-tumor level for the first time and provided opportunities for understanding the heterogeneity and individualized target therapy for this disease.Lihua Peng Rui Xing Dongbing Liu Li Bao Wenxiang Cheng Hongyi Wang Yuan Yu Xiaofeng Liu Lu Jiang Yan Wu Zhongxue An Qiaoyi Liang Ryong Nam Kim Young Kee Shin Huanming Yang Jian Wang Jun Yu Xiuqing Zhang Xun Xu Jiaan Yang Kui Wu Shida Zhu Youyong Lu 2019Science Bulletin2019,64,4:3

7Wave-front correction of high-intensity fs laser beams by using closed-loop adaptive optics system显示文摘We developed an adaptive optics system to correct the wave-front distortion of an intense fs laser beam from our multi-TW laser system, Jiguang II. In this paper, the instruments of the adaptive optical system are described and the experimental results of the closed-loop wave-front correction are presented. A distorted laser wave-front of 20 wavelengths of P-V values was corrected to 0.15 wavelength of P-V values. The beam quality of the laser system varies from 3.5 diffraction limit to 1.5 diffraction limit.WANG Zhaohua JIN Zhan ZHENG Jiaan WANG Peng WEI Zhiyi ZHANG Jie 2005Science China(Physics,Mechanics & Astronomy)2005,48,1:2
8Microstructures and mechanical properties of extruded Mg-2Sn-xYb(x=0,0.1,0.5 at.%)sheets显示文摘Microstructures and mechanical properties of extruded Mg-2Sn-xYb(x=0,0.1,0.5 at.%)sheets were investigated.The grain size of as-cast Mg-2Sn alloy is significantly reduced with increasing Yb concentration.In addition toα-Mg and Mg_(2)Sn phase,some fine Mg_(2)(Sn,Yb)particles are observed in as-cast Mg-2Sn-0.5Yb alloy,but these fine particles are not observed in as-cast Mg-2Sn-0.1Yb alloy due to a high solubility of Yb in Mg matrix.Tensile tests demonstrated that extruded Mg-2Sn-0.5Yb sheet exhibited the highest tensile strength and available elongation to failure at room temperature,while extruded Mg-2Sn-0.1Yb alloy exhibited the highest tensile properties at 100°C and 200°C.The difference in the tensile properties of extruded sheets mainly arises from the different strengthening roles of grain refinement,solid solution strengthening and precipitation strengthening of particles.Jing Jiang Guangli Bi Jiaan Liu ChunChun Ye Jianshe Lian Zhonghao Jiang 2014Journal of Magnesium and Alloys2014,2,3:2

17Optically probing molecular shuttling motion of[2]rotaxane by a conformation-adaptive fluorophore显示文摘A bistable[2]rotaxane with a conformation-adaptive macrocycle bearing a 9,14-diphenyl-9,14-dihydrodibenzo[a,c]phenazine(DPAC)unit was synthesized,which could be utilized to optical probe the molecular shuttling motion of the functionalized rotaxane system.The UV-vis,^(1) H NMR and PL spectroscopic data clearly demonstrated that the DPAC ring was interlocked onto the thread and the fluorescence intensity of the DPAC unit in the macrocycle was effectively regulated by the location change of the macrocycle along the thread under acid/base stimulation,which was attributed to the modulation of the intramolecular photo-induced electron transfer between the DPAC unit and the methyltriazole(MTA)unit.This bistable rotaxane system containing a conformation-adaptive fluorophore unit in the macrocycle moiety opens an alternative way to design functional bistable mechanically interlocked molecules.Chengyuan Yu Xiaodong Wang Cai-Xin Zhao Shun Yang Jiaan Gan Zhuo Wang Zhanqi Cao Da-Hui Qu 2022Chinese Chemical Letters2022,33,11:1
