| 2 | Genetic analysis and gene mapping of a dominant presenescing leaf gene PSL3 in rice (Oryza sativa L.)显示文摘Leaf senescence as an active process is essential for plant survival and reproduction.However,premature senility is harmful to agricultural production.In this study,a rice mutant,named as psl3 (presescing leaf 3) isolated from EMS-treated Jinhui 10,displays obvious premature senility features both in morphological and physiological level.Genetic analysis showed that mutant trait was controlled by a single dominant gene (PSL3),which was located on rice chromosome 7 between SSR marker c7sr1 and InDel marker ID10 with an interval of 53.5 kb.The result may be useful for the isolation of the PSL3 gene. | FANG LiKui LI YunFeng GONG XiaoPing SANG XianChun LING YingHua WANG XiaoWen CONG YunFei HE GuangHua | 2010 | Chinese Science Bulletin2010，55，23： | 20 |
| 3 | Geothermal data analysis at the high-temperature hydrothermal area in Western Sichuan显示文摘The western Sichuan hydrothermal area is located at the northeastern margin of the eastern syntaxis of the Qinghai-Tibet Plateau, which is also the eastern end of the Mediterranean-Himalayan geothermal activity zone. There are 248 warm or hot springs in this area, and 11 have temperatures beyond the local boiling temperature. Most of these hot springs are distributed along the Jinshajiang, Dege-Xiangcheng, Ganzi-Litang, and Xianshuihe faults, forming a NW-SE hydrothermal belt. A geothermal analysis of this high-temperature hydrothermal area is an important basis for understanding the deep geodynamic process of the eastern syntaxis of the Qinghai-Tibet Plateau. In addition, this study offers an a priori view to utilize geothermal resources, which is important in both scientific research and application. We use gravity, magnetic, seismic, and helium isotope data to analyze the crust-mantle heat flow ratio and deep geothermal structure. The results show that the background terrestrial heat flow descends from southwest to northeast. The crustal heat ratio is not more than 60%. The high temperature hydrothermal active is related to crustal dynamics processes. Along the Batang-Litang-Kangding line, the Moho depth increases eastward, which is consistent with the changing Qc/Qm(crustal/mantle heat flow) ratio trend. The geoid in the hydrothermal zone is 4–6 km higher than the surroundings, forming a local 'platform'. The NW-SE striking local tensile stress zone and uplift structure in the upper and middle crust corresponds with the surface hydrothermal active zone. There is an average Curie Point Depth(CPD) of 19.5–22.5 km in Batang, Litang, and Kangding. The local shear-wave(S-wave) velocity is relatively low in the middle and lower crust. The S-wave shows a low velocity trap(Vs<3.2 km s.1) at 15–30 km, which is considered a high-temperature partial melting magma, the crustal source of the hydrothermal active zone. We conclude that the hydrothermal system in this area can be divided into Batang-type and Kangding-type, both of which rely on a crustal heating cycle of atmospheric precipitation and surface water along the fracture zone. The heat is derived from the middle and lower crust: groundwater penetrates the deep faults bringing geothermal energy back to the surface and forming high-temperature springs. | ZHANG Jian LI WuYang TANG XianChun TIAN Jiao WANG YingChun GUO Qi PANG ZhongHe | 2017 | Science China Earth Sciences2017，60，8： | 17 |
| 4 | Notch signaling in blood vessels: from morphogenesis to homeostasis显示文摘Notch signaling is an evolutionarily conserved intercellular signaling pathway that plays numerous crucial roles in vascular development and physiology.Compelling evidence indicates that Notch signaling is vital for vascular morphogenesis including arterial and venous differentiation and endothelial tip and stalk cell specification during sprouting angiogenesis and also vessel maturation featured by mural cell differentiation and recruitment.Notch signaling is also required for vascular homeostasis in adults by keeping quiescent phalanx cells from re-entering cell cycle and by modulating the behavior of endothelial progenitor cells.We will summarize recent advances of Notch pathway in vascular biology with special emphasis on the underlying molecular mechanisms. | ZHANG Ping YAN XianChun CHEN Yan YANG ZiYan HAN Hua | 2014 | Science China(Life Sciences)2014，57，8： | 15 |
| 5 | Breeding wheat for resistance to Fusarium head blight in the Global North: China, USA, and Canada显示文摘The objective of this paper is to review progress made in wheat breeding for Fusarium head blight(FHB) resistance in China, the United States of America(USA), and Canada. In China,numerous Chinese landraces possessing high levels of FHB resistance were grown before the 1950 s. Later, pyramiding multiple sources of FHB resistance from introduced germplasm such as Mentana and Funo and locally adapted cultivars played a key role in combining satisfactory FHB resistance and high yield potential in commercial cultivars.Sumai 3, a Chinese spring wheat cultivar, became a major source of FHB resistance in the USA and Canada, and contributed to the release of more than 20 modern cultivars used for wheat production, including the leading hard spring wheat cultivars Alsen, Glenn, Barlow and SY Ingmar from North Dakota, Faller and Prosper from Minnesota, and AAC Brandon from Canada. Brazilian wheat cultivar Frontana, T. dicoccoides and other local germplasm provided additional sources of resistance. The FHB resistant cultivars mostly relied on stepwise accumulation of favorable alleles of both genes for FHB resistance and high yield,with marker-assisted selection being a valuable complement to phenotypic selection. With the Chinese Spring reference genome decoded and resistance gene Fhb1 now cloned, new genomic tools such as genomic selection and gene editing will be available to breeders, thus opening new possibilities for development of FHB resistant cultivars. | Zhanwang Zhu Yuanfeng Hao Mohamed Mergoum Guihua Bai Gavin Humphreys Sylvie Cloutier Xianchun Xia Zhonghu He | 2019 | The Crop Journal2019，7，6： | 12 |
| 6 | Effect of TiO_2 on Crystallization of the Glass Ceramics Prepared from Granite Tailings显示文摘The effect of TiO2 on the crystallization behaviors of the glass ceramics prepared from granite tailings was investigated by differential scanning calorimetry(DSC), X-ray diffraction(XRD), and field emission scanning electron microscopy(FESEM). The results showed that the crystallization peak temperature decreased firstly, and then increased with the increase of TiO2 content. The optimum addition amount of TiO2 was 8 wt%. With a single-step heat treatment at 924 ℃ for 1 h, augite precipitated as the only crystalline phase both on the surface and in the interior. The avrami parameter of the sample was 3.25, suggesting a twodimensional crystallization mechanism. The activation energies for phase separation and crystallization of augite were 321.75 and 698.83 k J/mol, respectively. | 程金树 KANG Junfeng LOU Xianchun ZHANG Xiaoman LIU Kai WANG Wentian HUAI Xuguang | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，1： | 9 |
| 7 | Responses of vegetation cover to the Grain for Green Program and their driving forces in the He-Long region of the middle reaches of the Yellow River显示文摘The implementation of the Grain for Green Program is a great breakthrough in the history of China's ecological environment construction,which can control soil erosion effectively,increase land productivity and improve the ecological environment.To investigate the eco-environmental benefits brought by the Grain for Green Program,the spatiotemporal variations of vegetation cover in the growing season from 2000 to 2010 across the Hekou-Longmen(He-Long) region were analyzed by using remote sensing information,meteorological data and land use data.Moreover,the impacts of climate and human activities on vegetation change were evaluated objectively.Annual vegetation cover in the growing season increased very significantly.Increased vegetation cover occurred in 98.7% of the region,of which the area for vegetation cover improved slightly constituted 79.8% of the whole area.Vegetation moderately improved was mainly distributed in the south of the He-Long region,covering 9.6% of the area,and the area for vegetation basically unchanged concentrated in the middle and upper reaches of the Wuding River.Precipitation was found to be an important natural factor influencing vegetation cover change.The area of vegetation cover showing a significantly positive correlation with precipitation occupied 22.14% of the region.As driven by policies from the Grain for Green Program,forestland increased significantly and land use structure became more intensive.Human activities played a positive and effective role in the protection,restoration and improvement of vegetation in the places where vegetation cover was basically unchanged,even though precipitation declined greatly,and vegetation improved moderately with massive increases of forestland and grassland. | JianXiang LIU ZhiGuang LI XiaoPing ZHANG Rui LI XianChun LIU HanYang ZHANG | 2013 | Journal of Arid Land2013，5，4： | 7 |
| 8 | Inclusion of the Eastern Asia endemic genus Sorolepidium in Polystichum (Dryopteridaceae):Evidence from the chloroplast rbcL gene and morphological characteristics显示文摘The taxonomic status of the Eastern Asia endemic Sorolepidium is controversial. Some authors accept it as member of the large diverse genus Polystichum, whereas others suggest that it is an independent genus separated from the later by the exindusiate sorus and the absence of aristate teeth at the pinnae margins. Here we infer phylogenetic relationship of Sorolepidium using DNA sequences of the chloro-plast rbcL gene. Phylogenies were inferred using maximum-parsimony, maximum-likelihood, and Bayesian inference methods. Molecular data establish that Sorolepidium is deeply nested within the large genus Polystichum and has a close relationship with P. duthiei and P. lachenense in the model-based analyses. The Kimura 2-parameter distances of the rbcL sequences between S. glaciale and P. duthiei and P. lachenense were 0.1 and 0.2%, respectively. Furthermore, S. glaciale differed from P. duthiei by a single nucleotide in their rbcL sequences. Close relationships between S. glaciale and P. duthiei and P. lachenense are also supported by the shared spore ornamentation with echinate fenes-trate folds. | LIU HongMei ZHANG XianChun CHEN ZhiDuan QIU YinLong | 2007 | Chinese Science Bulletin2007，52，5： | 6 |
| 9 | Promoting Effects of Pt on the Catalytic Performance of Supported NiB Amorphous Alloy Catalysts for Benzene Hydrogenation显示文摘A support(denoted AM) was prepared using pseudo-boehmite and mordenite.Ni-B and NiPtB amorphous catalysts were prepared on the support by the impregnation method followed by chemical reduction with a KBH4 solution.And the catalysts were characterized by X-ray diffraction(XRD),environment scanning electron microscope(ESEM),inductively coupled plasma(ICP),H2-temperature programmed reduction(H2-TPR),differential thermal analysis(DTA),and BET.Benzene hydrogenation was used as a probe reaction to evaluate the effect of addition of small quantities of Pt on the NiB/AM catalyst.The results show that Pt can promote the reduction of NiO and the formation of active sites,leading to smaller catalyst particles and better dispersion of active metal particles on the support.The catalytic activity,sulfur resistance and thermal stability were remarkably improved by Pt doping of the NiB/AM catalyst. | SONG Hua WU Xianchun WANG Huaiyuan LI Feng | 2011 | Chinese Journal of Chemical Engineering2011，19，4： | 6 |

| 11 | Development of image-based wheat spike counter through a Faster R-CNN algorithm and application for genetic studies显示文摘Spike number(SN) per unit area is one of the major determinants of grain yield in wheat. Development of high-throughput techniques to count SN from large populations enables rapid and cost-effective selection and facilitates genetic studies. In the present study, we used a deep-learning algorithm, i.e., Faster Region-based Convolutional Neural Networks(Faster R-CNN) on Red-Green-Blue(RGB) images to explore the possibility of image-based detection of SN and its application to identify the loci underlying SN. A doubled haploid population of 101 lines derived from the Yangmai 16/Zhongmai 895 cross was grown at two sites for SN phenotyping and genotyped using the high-density wheat 660 K SNP array.Analysis of manual spike number(MSN) in the field, image-based spike number(ISN), and verification of spike number(VSN) by Faster R-CNN revealed significant variation(P < 0.001) among genotypes, with high heritability ranged from 0.71 to 0.96. The coefficients of determination(R^(2)) between ISN and VSN was 0.83, which was higher than that between ISN and MSN(R^(2)= 0.51), and between VSN and MSN(R^(2)= 0.50). Results showed that VSN data can effectively predict wheat spikes with an average accuracy of 86.7% when validated using MSN data. Three QTL Qsnyz.caas-4 DS, Qsnyz.caas-7 DS, and QSnyz.caas-7 DL were identified based on MSN, ISN and VSN data, while QSnyz.caas-7 DS was detected in all the three data sets. These results indicate that using Faster R-CNN model for image-based identification of SN per unit area is a precise and rapid phenotyping method, which can be used for genetic studies of SN in wheat. | Lei Li Muhammad Adeel Hassan Shurong Yang Furong Jing Mengjiao Yang Awais Rasheed Jiankang Wang Xianchun Xia Zhonghu He Yonggui Xiao | 2022 | The Crop Journal2022，10，5： | 5 |
| 12 | Genetic analysis and molecular mapping of a novel gene for zebra mutation in rice (Oryza sativa L.)显示文摘A novel zebra mutant,zebra-15,derived from the restorer line Jinhui10(Oryza sativa L. ssp. indica) treated by EMS,displayed a distinctive zebra leaf from seedling stage to jointing stage. Its chlorophyll content decreased(55.4%) and the ratio of Chla/Chlb increased(90.2%) significantly in the yellow part of the zebra-15,compared with the wild type. Net photosynthetic rate and fluorescence kinetic parameters showed that the decrease of chlorophyll content significantly influenced the photosynthetic efficiency of the mutant. Genetic analysis of F2 segregation populations derived from the cross of Xinong1A and zebra-15 indicated that the zebra leaf trait is controlled by a single recessive nuclear gene. Ninety-eight out of four hundred and eighty pairs of SSR markers showed the diversity between the Xinong1A and the zebra-15,their F2 population was then used for gene mapping. Zebra-15(Z-15) gene was primarily restricted on the short arm of chromosome 5 by 150 F2 recessive individuals,19.6 cM from marker RM3322 and 6.0 cM from marker RM6082. Thirty-six SSR markers were newly designed in the restricted location,and the Z-15 was finally located between markers nSSR516 and nSSR502 with the physical region 258 kb by using 1,054 F2 recessive individuals. | Qiushi Wang,Xianchun Sang,Yinghua Ling,Fangming Zhao,Zhenglin Yang,Yunfeng Li,Guanghua He Key Laboratory of Biotechnology and Crop Quality Improvement,Ministry of Agriculture Rice Research Institute,Southwest University,Chongqing 400716,China | 2009 | Journal of Genetics and Genomics2009，36，11： | 5 |
| 13 | Lodging resistance and yield potential of winter wheat:effect of planting density and genotype显示文摘Improved lodging resistance is important for achieving high yield in irrigated environments.This study was conducted to determine genotypic variation in lodging resistance and related morphological traits among winter wheat cultivars planted at two densities,and to identify key traits associated with lodging resistance.Lodging performance of 28 genotypes,including 24 released cultivars and four advanced lines,was evaluated at 250 plants per square meter and 500 plants per square meter in Shandong province during the 2008–2009 and 2009–2010 crop seasons.At the higher density,the average grain yield was 2.6%higher,even though lodging score rose by as much as 136%.The higher planting density increased lodging through increased leaf area index(LAI),plant height,center of gravity and length of basal internodes,and reduced grain weight per spike and diameter of the lower two stem internodes.LAI,center of gravity and diameter of first internodes,as the important indicators for lodging resistance,were significantly correlated with lodging score,with R=0.62,0.59 and–0.52(P<0.01),respectively.Plant pushing resistance was significantly associated with diameter and length of the first internodes(R=0.71–0.77,P<0.01),indicating it could be used to assess the strength of the lower stem.Higher planting density could be used to select genotypes with lodging resistance in irrigated environments.Cultivars carrying high plant density tolerance and high yield potential,such as Jimai 22 and Liangxing 66,were recommended as leading cultivars for production as well as elite crossing parents for further increasing yield potential in the Yellow and Huai Valleys Winter Wheat Zone in China. | Yonggui XIAO Jianjun LIU Haosheng LI Xinyou CAO Xianchun XIA Zhonghu HE | 2015 | Frontiers of Agricultural Science and Engineering2015，2，2： | 5 |
| 14 | Endothelial cells-targeted soluble human Delta-like 4 suppresses both physiological and pathological ocular angiogenesis显示文摘Due to its essential roles in angiogenesis, Notch pathway has emerged as an attractive target for the treatment of pathologic angiogenesis. Although both activation and blockage of Notch signal can impede angiogenesis, activation of Notch signal may be more promising because it was shown that long-term Notch signal blockage resulted in vessel neoplasm. However, an in vivo deliverable Notch ligand with highly efficient Notch-activating capacity has not been developed. Among all the Notch ligands, Delta-like4(Dll4) is specifically involved in angiogenesis. In this study, we generated a novel soluble Notch ligand h D4 R, which consists of the Delta-Serrate-Lag-2 fragment of human Dll4 and an arginine-glycine-aspartate(RGD) motif targeting endothelial cells(ECs). We demonstrated that h D4 R could bind to ECs through its RGD motif and effectively triggered Notch signaling in ECs. Further, we confirmed that h D4 R could suppress angiogenesis in vitro as manifested by network formation assay and sprouting assay. More importantly, h D4 R efficiently repressed neonatal retinal angiogenesis and laser-induced choroidal neovascularization(CNV) as well in vivo. In conclusion, we have developed an in vivo deliverable Notch ligand h D4 R, which suppresses angiogenesis both in vitro and in vivo, thus providing a new approach to tackle excessive angiogenesis relevant disease such as CNV. | YAN XianChun YANG ZiYan CHEN Yan LI Na WANG Li DOU GuoRui LIU Yuan DUAN JuanLi FENG Lei DENG SanMing HAN Hua ZHANG Ping | 2015 | Science China(Life Sciences)2015，58，5： | 5 |
| 15 | Genome-wide association mapping of vitamins B1 and B2 in common wheat显示文摘Vitamin B is essential for maintaining normal life activities in humans and animals who have to intake the microelement from the outside, especially from cereal products. In the present study 166 Chinese and foreign wheat cultivars planted in two environments were characterized for variation in vitamin B1 and B2 contents. A genome-wide association study(GWAS) using the wheat 90 K SNP assay identified 17 loci for vitamin B1 and 7 for vitamin B2 contents. Linear regression analysis showed a significantly positive correlation of the number of favorable alleles with vitamin B1 and B2 contents. Marker-trait associations(MTAs) at IWB43809(6AS, 0cM) and IWB69903(6AS, 13cM) were new and stable, and significantly associated with vitamin B1 content across two environments. The loci identified in this study and associated SNP markers could be used for improvement of vitamin B1 and B2 contents to obtain superior quality along with grain yield in wheat. | Jieyun Li Jindong Liu Wei'e Wen Pingzhi Zhang Yingxiu Wan Xianchun Xia Yan Zhang Zhonghu He | 2018 | The Crop Journal2018，6，3： | 4 |
| 16 | Identification and gene mapping of a narrow and upper-albino leaf mutant in rice(Oryza sativa L.)显示文摘The leaf blade consists of color and shape traits.Studies of leaf-blade development are important for improvement of rice yield and quality because it is an essential organ for photosynthesis.A narrow and upper-albino leaf mutant(nul1) was identified from among progeny of the indica restorer line Jinhui10 raised from seeds treated with ethyl methane sulfonate.Under field conditions,the mutant displayed narrow and upper-albino leaf blades with significantly decreased photosynthetic pigment contents throughout their development.The narrow-leaf trait is caused by a decreased number of small veins.In contrast to the wild type,the growth period was extended by approximately 8 d and agronomic traits,such as effective panicle number,percentage seed set and 1000-grain weight,declined significantly in the nul1 mutant.Genetic analysis suggested that the narrow and upper-albino leaf characteristics showed coseparation and were controlled by one recessive gene.The Nul1 gene was mapped onto chromosome 7 between the Indel marker Ind07-1 and the Simple Sequence Repeat marker RM21637.The physical distance between the markers was 75 kb and eight genes were annotated in this region based on the rice Nipponbare genome sequence.These results provide a foundation for cloning and function analysis of Nul1. | WANG Feng TANG YanQiang MIAO RunLong XU FangFang LIN TingTing HE GuangHua SANG XianChun | 2012 | Chinese Science Bulletin2012，57，28： | 4 |
| 17 | A novel graphene oxide-carbon nanotubes anchored α-FeOOH hybrid activated persulfate system for enhanced degradation of Orange Ⅱ显示文摘Persulfate activation has been applied as one of the efficient advanced oxidation processes(AOPs) to remediate polluted environments. In this study, a novel α-FeOOH anchored by graphene oxide(GO)-carbon nanotubes(CNTs) aerogel(α-FeOOH@GCA) nanocomposite activated persulfate system(α-FeOOH@GCA + K2S2O8) was applied for decolorization of Orange Ⅱ(OⅡ). The decolorization of OⅡ was remarkably enhanced to a level of ~ 99% in this system compared with that of pristine α-FeOOH(~ 44%) or GO-CNTs(~18%). The enhanced catalytic activity of α-FeOOH@GCA was due to the formation of a heterojunction byα-FeOOH and GO-CNTs as confirmed by the presence of Fe–O–C chemical bonds. The degradation intermediates of OⅡ were comprehensively identified. The proposed degradation pathway of OⅡ begins with the destruction of the conjugated structures of OⅡ by the dominant reactive oxygen species, surface-bound SO4·-. The decolorization efficiency of OⅡ by the α-FeOOH@GCA activated persulfate system decreased from the first to third cycle of recycling. Ultraviolet(UV) irradiation or introduction of a small amount of Fe2+ could restore the activation of this system. The results show that the α-FeOOH@GCA persulfate activation system promises to be a highly efficient environmental remediation method for organic pollutants. | Shanshan Su Yuyang Liu Wei He Xianchun Tang Wei Jin Yaping Zhao | 2019 | Journal of Environmental Sciences2019，31，9： | 4 |

| 19 | Morphological and physiological analysis of narrow and striped leaf 1(nsl1) mutant of rice(Oryza sativa L.) and the gene mapping显示文摘The shape and color of rice leaves are important agronomic traits that directly influence the proportion of sunlight energy utilization and ultimately affect the yield and quality.A new mutant exhibiting stable inheritance was identified as derived from ethyl methane sulfonate(EMS)-treated restorer Jinhui 10,tentatively named as narrow and striped leaf 1(nsl1).The nsl1 displayed pale white leaves at the seeding stage and then white striped leaves in parallel to the main vein at the jointing stage.Meanwhile,its leaf blades are significantly narrower than the control group of Jinhui 10.The chloroplast structures of cells in the white striped area of the nsl1 mutant break down,and the photosynthetic pigments are significantly lower than that of the wild type.Moreover,fluorescence parameters,such as F0,F v/F m,U psII,qp,and ETR,in the nsl1 mutant are significantly lower than those of the wild type,and the photosynthetic efficiency is also significantly decreased.These changes in leaf color and shape,together with physiological changes in the nsl1,result in smaller plant height and a decrease in the most important agronomic traits,such as the number of grains per panicle,grain weight,etc.Genetic analysis shows that the narrow and striped traits of the nsl1 mutant are controlled by a single recessive nuclear gene,which is located between InDel 16and InDel 12 in chromosome 3.The physical distance is204 kb.So far,no similar genes of such leaf color and shape in this area have been reported.This study has laid a solid foundation for the gene cloning and function analysis of NSL1. | Fangming Zhao Yong Zhang Yanru Wu Tongming Wang Ling Ma Zhenglin Yang Xia Wei Xianchun Sang Yinghua Ling Nan Wang Changwei Zhang Guanghua He | 2014 | Chinese Science Bulletin2014，59，9： | 3 |
