| 1 | Factors Affecting Sensory Quality of Cooked japonica Rice显示文摘The sensory quality of cooked rice is an important factor in determining its market price, as well as consumer acceptance and breeding efforts aimed at improvement of rice grain quality. In this study,the sensory quality and physicochemical properties of three japonica rice varieties harvested in two different growing locations(Xiangshui and Hangzhou of China) were compared to determine the most important factors affecting the sensory quality. All the three varieties had higher scores for overall sensory quality in Xiangshui than in Hangzhou, indicating that the growing location is a key factor in determining the sensory quality of cooked japonica rice. In addition to growing location, variety(genotype) also had an important effect. Longdao 18 scored the highest for overall sensory quality in the two locations, whereas Longdao 30 had the lowest score in Xiangshui, and both Longdao 20 and Longdao 30 had the lowest scores in Hangzhou. Many physicochemical properties, such as apparent amylose content, protein content, thermal properties and free amino acid contents, showed significant differences between the two locations. Correlation analysis showed that apparent amylose content and protein content had contrasting effects on all the sensory attributes. The overall sensory quality was negatively correlated with protein content(r =-0.89, P < 0.01) and positively correlated with gel hardness(r = 0.91, P < 0.01),indicating that the protein content and hardness are important physicochemical properties for predicting the sensory quality of japonica rice. These findings will provide guidance for selection from the diverse genotypes available to develop new varieties with the desired eating and cooking quality. | XU Yanjie YING Yining OUYANG Shuhong DUAN Xiaoliang SUN Hui JIANG Shukun SUN Shichen BAO Jinsong | 2018 | Rice science2018，25，6： | 23 |
| 2 | Integrating eye-movement analysis and the semantic differential method to analyze the visual effect of a traditional commercial block in Hefei, China显示文摘Eye-movement analysis was adopted to evaluate the visual perception of Chinese traditional commercial blocks,and the Chenghuangmiao block in Hefei,China,was selected as a typical case.Eye-movement data from 40 respondents viewing 14 sample pictures were recorded.The spatial elements of the sample pictures,including landmarks and commercial brands,were further extracted to analyze the visual characteristics of spatial elements and the factors that affect the respondents’perceptions of those elements.Then,the semantic differential method was used to analyze the relationship between visual preferences and psychological perceptions of spatial elements.Seventeen pairs of opposing adjectives were selected to score the intrinsic properties and visitors,feelings of spaces.The software SPSS 22.0 was used to analyze these data.Results showed that distinctive spatial elements,such as street corridors,Ma Tau Walls,and various landmarks,were the most visually attractive.In addition,the location of a given element within a picture was an important factor affecting eye movements.On this basis,strategies for improving spatial-visual effects are proposed.The strategies include emphasizing the visual characteristics of different spatial elements,considering the overall layout of spatial elements,and creating diversified spaces based on different spatial categories. | Zao Li Xia Sun Shichen Zhao Hongwei Zuo | 2021 | Frontiers of Architectural Research2021，10，2： | 5 |
| 3 | Variations in OsSPL10 confer drought tolerance by directly regulating OsNAC2 expression and ROS production in rice显示文摘Drought is a major factor restricting the production of rice(Oryza sativa L.).The identification of natural variants for drought stress-related genes is an important step toward developing genetically improved rice varieties.Here,we characterized a member of the SQUAMOSA PROMOTER BINDING PROTEIN-LIKE(SPL)family,OsSPL10,as a transcription factor involved in the regulation of drought tolerance in rice.OsSPL10 appears to play a vital role in drought tolerance by controlling reactive oxygen species(ROS)production and stomatal movements.Haplotype and allele frequency analyses of OsSPL10 indicated that most upland rice and improved lowland rice varieties harbor the OsSPL10Hap1allele,whereas the OsSPL10Hap2allele was mainly present in lowland and landrace rice varieties.Importantly,we demonstrated that the varieties with the OsSPL10Hap1allele showed low expression levels of OsSPL10 and its downstream gene,OsNAC2,which decreases the expression of OsAP37 and increases the expression of OsCOX11,thus preventing ROS accumulation and programmed cell death(PCD).Furthermore,the knockdown or knockout of OsSPL10 induced fast stomatal closure and prevented water loss,thereby improving drought tolerance in rice.Based on these observations,we propose that OsSPL10 confers drought tolerance by regulating OsNAC2 expression and that OsSPL10Hap1could be a valuable haplotype for the genetic improvement of drought tolerance in rice. | Yingxiu Li Shichen Han Xingming Sun Najeeb Ullah Khan Qun Zhong Zhanying Zhang Hongliang Zhang Feng Ming Zichao Li Jinjie Li | 2023 | Journal of Integrative Plant Biology2023，65，4： | 2 |
| 4 | Rice SPL10 positively regulates trichome development through expression of HL6 and auxin-related genes显示文摘Trichomes function in plant defenses against biotic and abiotic stresses;examination of glabrous lines,which lack trichomes,has revealed key aspects of trichome development and function.Tests of allelism in 51 glabrous rice(Oryza sativa)accessions collected worldwide identified OsSPL10 and OsWOX3B as regulators of trichome development in rice.Here,we report that OsSPL10 acts as a transcriptional regulator controlling trichome development.Haplotype and transient expression analyses revealed that variation in the approximately 700-bp OsSPL10 promoter region is the primary cause of the glabrous phenotype in the indica cultivar WD-17993.Disruption of OsSPL10 by genome editing decreased leaf trichome density and length in the NIL-HL6 background.Plants with genotype OsSPL10^(WD-17993)/HL6 generated by crossing WD-17993 with NIL-HL6 also had fewer trichomes in the glumes.HAIRY LEAF6(HL6)encodes another transcription factor that regulates trichome initiation and elongation,and OsSPL10 directly binds to the HL6 promoter to regulate its expression.Moreover,the transcript levels of auxin-related genes,such as OsYUCCA5 and OsPIN-FORMED1b,were altered in OsSPL10 overexpression and RNAi transgenic lines.Feeding tests using locusts(Locusta migratoria)demonstrated that non-glandular trichomes affect feeding by this herbivore.Our findings provide a molecular framework for trichome development and an ecological perspective on trichome functions. | Jinjie Li Bo Tang Yingxiu Li Chenguang Li Minjie Guo Haiyang Chen Shichen Han Jin Li Qijin Lou Wenqiang Sun Peng Wang Haifeng Guo Wei Ye Zhanying Zhang Hongliang Zhang Sibin Yu Long Zhang Zichao Li | 2021 | Journal of Integrative Plant Biology2021，63，8： | 2 |
| 5 | Propagation properties of foreshock cavitons: Cluster observations显示文摘Foreshock cavitons are transient phenomena observed in the terrestrial foreshock region.They are characterized by a simultaneous depression of magnetic field magnitude and plasma density,which are bounded with enhancements of these two parameters and surrounded by ultralow frequency(ULF)waves.Previous studies focused on the interplanetary magnetic field(IMF)conditions,solar wind(SW)conditions,and the growth of the foreshock waves related to the generation of foreshock cavitons.Previously,a multipoint spacecraft analysis method using Cluster data was applied to analyze only two foreshock cavitons,and this method did not consider uncertainties.In this study,multipoint spacecraft analysis methods,including the timing method,the minimum directional derivative(MDD)method,and the spatiotemporal difference(STD)method are applied to determine the velocity in both spacecraft and solar wind frames.The propagation properties show good agreement with previous results from simulations and observations that most cavitons move sunward in the solar wind frame,with the velocities larger than the Alfvén speed.The propagation properties of foreshock cavitons support the formation mechanism of cavitons in previous simulations,which suggested that cavitons are formed due to the nonlinear evolution of compressive ULF waves.We find that there is clear decreasing trend between the size of cavitons and their velocity in the solar wind frame.In addition,the timing method considering errors has been applied to study the evolution properties by comparing the velocities with errors of the leading and trailing edges,and we identify three stable cavitons and one contracting caviton,which has not been studied before.Most cavitons should remain stable when they travel toward the Earth’s bow shock.The relationship between the size of foreshock cavitons and their distance from the bow shock is also discussed. | WANG MengMeng YAO ShuTao SHI QuanQi ZHANG Hui TIAN AnMin DEGELING Alexander William ZHANG Shuai GUO RuiLong SUN WeiJie LIU Ji BAI ShiChen SHEN XiaoChen ZHU XiaoQiong FU SuiYan PU ZuYin | 2020 | Science China(Technological Sciences)2020，63，1： | 1 |
| 6 | Upconversion nanoparticles regulated drug&gas dual-effective nanoplatform for the targeting cooperated therapy of thrombus and anticoagulation显示文摘Thromboembolism is the leading cause of cardiovascular mortality.Currently,for the lack of targeting,short half-life,low bioavailability and high bleeding risk of the classical thrombolytic drugs,pharmacological thrombolysis is usually a slow process based on micro-pumping.In addition,frequently monitoring and regulating coagulation functions are also required during(and after)the process of thrombolysis.To address these issues,a targeted thrombolytic and anticoagulation nanoplatform(UCATS-UK)is developed based on upconversion nanoparticles(UCNPs)that can convert 808 or 980 nm near-infrared(NIR)light into UV/blue light.This nanoplatform can target and enrich in the thrombus site.Synergistic thrombolysis and anticoagulation therapy thus could be realized through the controlled release of urokinase(UK)and nitric oxide(NO).Both in vitro and in vivo experiments have confirmed the excellent thrombolytic and anticoagulative capabilities of this multifunctional nanoplatform.Combined with the unique fluorescent imaging capability of UCNPs,this work is expected to contribute to the development of clinical thrombolysis therapy towards an integrated system of imaging,diagnosis and treatment. | Shichen Liu Yao Sun Teng Zhang Longtao Cao Zhiwei Zhong Haoxin Cheng Qingqing Wang Zhuang Qiu Weimin Zhou Xiaolei Wang | 2022 | Bioactive Materials2022，7，12： | 1 |

| 8 | Terbium-doped zinc oxide constructed dual-light-responsive nitric oxide-releasing platform for bacterial keratitis treatment显示文摘Bacterial keratitis(BK)is a principal factor contributing to corneal ulcers and ocular complications,and has become a significant killer of global vision health.Traditional antibiotic therapy has unsatisfactory therapeutic effect due to short residence time and low utilization rate of drug,and the long-term abuse of antibiotics can easily incur the prevalence of drug-resistant bacteria.Furthermore,antibiotics are not effective in addressing the excessive inflammatory response caused by infection.Here,we developed a terbium-doped zinc oxide constructed dual-light-responsive nitric oxide(NO)-releasing nanoparticle(ZT@P@B)and modified it on the surface of contact lenses(CL-ZT@P@B)to boost its bioavailability.In vitro and in vivo experimental results verified that ZT@P@B could simultaneously respond to green light(GL)and 808 nm near-infrared(NIR)without obvious damage to the eyes,releasing reactive oxygen species(ROS)and NO,which could effectively kill bacteria(including drug-resistant strains)and reduce inflammatory response.The platform provides a promising strategy for the prevention and treatment of BK. | Yue Sun Wei Zhang Menghui Wang Huijie Liu Qun Li Jiazhe Luo Mengzhen Zhao Shichen Liu Xiaolei Wang | 2023 | Nano Research2023，16，1： | 0 |
| 9 | Morphological modification of Mg_(2)Si phase and strengthening mechanism in Mg_(2)Si/Al composites by Eu addition and T6 heat treatment显示文摘In order to improve mechanical properties of Mg_(2)Si/Al composites,Eu element was added to mod-ify Mg_(2)Si morphology,and T6 heat treatment was used to control Mg_(2)Si morphology and precipitate strengthening phase.Microstructure and morphology of Mg_(2)Si were observed by synchrotron X-ray to-mography and TEM,and first-principles calculations were also performed to testify the effect of Eu mod-ification.Results show that the size of primary Mg_(2)Si particles decreases and eutectic Mg_(2)Si phase trans-forms from lamellar to fibrous by Eu addition.After heat treatment,sharp angles of primary Mg_(2)Si par-ticles passivate,and eutectic Mg_(2)Si dissolves and appears to be short dot-like.Meanwhile,nano-sizedβ'phase precipitates in the matrix.For morphology of Mg_(2)Si with Eu modification,TEM results show that Eu impedes the growing of Mg_(2)Si,which is verified by first-principles calculations that Eu atom preferentially adsorbs on Mg_(2)Si{100}facet.The adsorption and suppression growing of Mg_(2)Si transform the morphology of Mg_(2)Si and thus improve the elongation.UTS and elongation of the heat-treated Eu modified composites are 281 MPa and 8.4%,which improved 81%and 200%compared to the as-cast Al-15%Mg_(2)Si composite.The strengthening mechanism mainly results from precipitation strengthening of nano-sizedβ'precipitates in the heat-treated composite. | Yinling Jin Hongze Fang Ruirun Chen Jiwei Wang Shichen Sun Shu Wang Bin Shao Jingjie Guo | 2023 | Journal of Materials Science & Technology2023，，28： | 0 |
