| 1 | 不同盐胁迫处理下番茄种子萌发期的耐盐性研究(英文)显示文摘[Objective] The aim of this study was to provide the theoretical basis for screening and utilizing salt-tolerant tomato varieties as well as for cultivating salt-resistance.[Method] Salinity tolerance of tomato during seed germination under simple salt sodium chloride and double salt calcium nitrate or sodium chloride stress were studied by Petri dish culturing.[Result] As the two kinds salt concentration increased,the germination regularity,the germination rate,the germination index and the growing vigor index of tomato seedlings decreased,but the germination losing rate increased.When salt concentration was from 0.2% to 0.4%,there was little difference among all indexes under two kinds of salt stress.However,when salt concentration was from 0.6% to 1.0%,the difference among all indexes under two kinds of salt stress was significant.[Conclusion] Salinity tolerance of tomato seeds under double salt calcium nitrate or sodium chloride stress was higher than that under simple salt sodium chloride stress. | 马洪英 郭锐 李洪安 张远芳 | 2008 | Agricultural Science & Technology2008，9，4： | 32 |
| 2 | Selected suitable seed cell, scaffold and growth factor could maximize the repair effect using tissue engineering method in spinal cord injury显示文摘Spinal cord injury usually leads to permanent disability, which could cause a huge financial problem to the patient. Up to now there is no effective method to treat this disease. The key of the treatment is to enable the damage zone axonal regeneration and luckily it could go through the damage zone; last a connection can be established with the target neurons. This study attempts to combine stem cell, material science and genetic modification technology together, by preparing two genes modified adipose-derived stem cells and inducing them into neuron direction; then by compositing them on the silk fibroin/chitosan scaffold and implanting them into the spinal cord injury model, seed cells can have features of neuron cells. At the same time, it could stably express the brain-derived neurotrophic factor and neurotrophin-3, both of which could produce synergistic effects, which have a positive effect on the recovery of spinal cord. The spinal cord scaffold bridges the broken end of the spinal cord and isolates with the surrounding environment, which could avoid a scar effect on the nerve regeneration and provide three-dimensional space for the seed cell growth, and at last we hope to provide a new treatment for spinal cord injury with the tissue engineering technique. | Wen-Chen Ji Xiao-Wei Zhang Yu-Sheng Qiu | 2016 | World Journal of Experimental Medicine2016，6，3： | 23 |

| 9 | ZmMs30 Encoding a Novel GDSL Lipase Is Essential for Male Fertility and Valuable for Hybrid Breeding in Maize显示文摘Genic male sterility (GMS) is very useful for hybrid vigor utilization and hybrid seed production. Although a large number of GMS genes have been identified in plants, little is known about the roles of GDSL lipase members in anther and pollen development. Here, we report a maize GMS gene, ZmMs30, which encodes a novel type of GDSL lipase with diverged catalytic residues. Enzyme kinetics and activity assays show that ZmMs30 has lipase activity and prefers to substrates with a short carbon chain. ZmMs30 is specifically expressed in maize anthers during stages 7-9. Loss of ZmMs30 function resulted in defective anther cuticle, irregular foot layer of pollen exine, and complete male sterility. Cytological and lipidomics analyses demonstrate that ZmMs30 is crucial for the aliphatic metabolic pathway required for pollen exine formation and anther cuticle development. Furthermore, we found that male sterility caused by loss of ZmMs30 function was stable in various inbred lines with different genetic background, and that it didn't show any negative effect on maize heterosis and production, suggesting that ZmMs30 is valuable for crossbreeding and hybrid seed production. We then developed a new multi-control sterility system using ZmMs30 and its mutant line, and demonstrated it is feasible for generating desirable GMS lines and valu. able for hybrid maize seed production. Taken together, our study sheds new light on the mechanisms of anther and pollen development, and provides a valuable male-sterility system for hybrid breeding maize. | Xueli An Zhenying Dong Youhui Tian Ke Xie Suowei Wu Taotao Zhu Danfeng Zhang Van Zhou Canfang Niu Biao Ma Quancan Hou Jianxi Bao Simiao Zhang Ziwen Li Yanbo Wang Tingwei Yan Xiaojing Sun Yuwen Zhang Jinping Li Xiangyuan Wan | 2019 | Molecular Plant2019，12，3： | 15 |
| 10 | Super absorbent polymer seed coatings promote seed germinationand seedling growth of Caragana korshinskii in drought显示文摘Coating seeds with water absorbent materials can improve their survival, especially for those planted indrought or barren areas. In this study, effects of five kinds of super absorbent polymers (SAPs) on seed germinationand seedling growth of Caragana korshinskii under drought conditions were investigated. Our results showed that SAPcoatings could significantly improve the percentage and energy of seed germination, as well as reduce the relativeelectrical conductivity (REC), proline, malondialdehyde (MDA), H202 content, and peroxidase (POD) activity duringgermination. These results implied that seeds could uptake moisture from SAP coatings to alleviate drought-inducedoxidative stress and membrane damage, thus exhibiting a better vigor and germination performance. After coating C.korshinskii seeds with SAPs, more seedlings emerged and grew better. Under the combined influence of the waterabsorption capacity of SAP and other factors, the efficiencies of five SAP coatings are in the sequence D〉E〉B〉A〉C.The function of the SAP coating on promoting seedling survival was confirmed in Mu Us Sandy Land in Ordos, InnerMongolia Autonomous Region, China. The average seedling number of SAP D-coated seeds increased twofold on thatof naked seeds. Our results are expected to be helpful in understanding and utilizing SAP seed coatings in improvingplant survival under drought conditions. | Li-qiang SU Jia-guo LI Hua XUE Xiao-feng WANG | 2017 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2017，18，8： | 15 |
| 11 | Inhibitory Effects of Grape Seed Proanthocyanidin Extract on Selenite-induced Cataract Formation and Possible Mechanism显示文摘This study investigated the inhibitory effect of grape seed proanthocyanidin extract(GSPE) on selenite-induced cataract formation in rats and the possible mechanism.Eighty 8-day-old Sprague-Dawley rats were divided randomly into 5 groups:control group,model group,three GSPE groups(low dose,medium dose and high dose).Control group received subcutaneous injection of physiological saline.Model group was given subcutaneous injection of sodium selenite(20 μmol/kg body weight) on the postpartum day 10,and once every other day for consecutive three times thereafter.GSPE treated groups were respectively administered GSPE at doses of 50,100,and 200 mg/kg body weight intragastrically 2 days prior to the selenite injection(that was,on the postpartum day 8),and once daily for fourteen consecutive days thereafter.The opacity of lenses was observed,graded and photographed under the slit lamp microscopy and the maximal diameter of the nuclear cataract plaques was measured.The lenses were analyzed for superoxide dismutase(SOD),catalase(CAT),glutathione peroxidase(GSH-PX),malondialdehyde(MDA),calcium(Ca 2+),nitric oxide(NO) and anti-hydroxyl radical ability(anti-OH).The histomorphology of lenses was observed with HE staining under a light microscope.The levels of calpainⅡ,and iNOS protein and mRNA expression in lenses were detected by using immunohistochemistry and real-time quantitative RT-PCR.The results showed subcutaneous injection of sodium selenite led to severe nuclear cataract in model group,and the achievement ratio of model group was 100%.As compared with model group,the degree of lenses opacity and the maximal diameter of nuclear cataract plaques were significantly reduced in GSPE-treated groups.Moreover,we observed selenite treatment caused a significant decrease in the activities of antioxidative enzymes(SOD,CAT,GSH-PX) and anti-OH ability,accompanied by a significant increase in the levels of MDA,NO,Ca 2+ as well as iNOS,and calpainⅡ protein and mRNA expression.Administration of GSPE could dose-dependently preserve the activities of these antioxidative enzymes and anti-OH ability,accompanied by a significant reduction in the levels of MDA,NO,Ca 2+ as well as iNOS,and calpainⅡ protein and mRNA expression.These results suggested that GSPE markedly prevented selenite-induced cataract formation probably by suppressing the generation of lipid peroxidation and free radicals as well as the activation of iNOS,and calpainⅡ in the lenses. | 张璇 胡义珍 | 2012 | Journal of Huazhong University of Science and Technology(Medical Sciences)2012，32，4： | 14 |
| 12 | Central role of the LEAFY COTYLEDON1 transcription factor in seed development显示文摘Seed development is a complex period of the flowering plant life cycle.After fertilization,the three main regions of the seed,embryo,endosperm and seed coat,undergo a series of developmental processes that result in the production of a mature seed that is developmentally arrested,desiccated,and metabolically quiescent.These processes are highly coordinated,both temporally and spatially,to ensure the proper growth and development of the seed.The transcription factor,LEAFY COTYLEDON1(LEC1),is a central regulator that controls several aspects of embryo and endosperm development,including embryo morphogenesis,photosynthesis,and storage reserve accumulation.Thus,LEC1 regulates distinct sets of genes at different stages of seed development.Despite its critical importance for seed development,an understanding of the mechanisms underlying LECi's multifunctionality is only beginning to be obtained.Recent studies describe the roles of specific transcription factors and the hormones,gibberellic acid and abscisic acid,in controlling the activity and transcriptional specificity of LEC1 across seed development.Moreover,studies indicate that LEC1 acts as a pioneer transcript!on factor to promote epigenetic reprogramming during embryogenesis.In this review,we discuss the mechanisms that enable LEC1 to serve as a central regulator of seed development. | Leonardo Jo Julie M.Pelletier John J.Harada | 2019 | Journal of Integrative Plant Biology2019，61，5： | 14 |

| 14 | A Regulatory Module Controlling CA-Mediated Endosperm Cell Expansion Is Critical for Seed Germination in Arabidopsis显示文摘A key component of seed germination is the interplay of mechanical forces governing embryo growth and the surrounding restraining endosperm tissue.Endosperm cell separation is therefore thought to play a critical role in the control of this developmental transition.Here we demonstrate that in Arabidopsis thaliana seeds,endosperm cell expansion is a key component of germination.Endosperm cells expand to accommodate embryo growth prior to germination.We show that this is an actively regulated process supported by spatiotemporal control of the cell expansion gene EXPANSIN 2 (EXPA2).The NAC transcription factors NAC25 and NACIL were identified as upstream regulators of EXPA2 expression,gibbereliinmediated endosperm expansion,and seed germination.The DELLA protein RGL2 repressed activation of the EXPA2 promoter by NAC25/NACIL.Taken together,our findings uncover a key role of the GA/ DELLA-NAC25/NACIL-EXPA2 network in regulating endosperm cell expansion to control the seed-toseedling transition. | Rocio Sanchez-Montesino Laura Bouza-Morcillo Julietta Marquez Melania Ghita Salva Duran-Nebreda Luis Gomez Michael J.Holdsworth George Bassel Luis Onate-Sanchez | 2019 | Molecular Plant2019，12，1： | 11 |
| 15 | Advances in fabrication of ceramic corundum abrasives based on sol–gel process显示文摘Corundum abrasives with good chemical stability can be fabricated into various free abrasives and bonded abrasive tools that are widely used in the precision machining of various parts.However,these abrasives cannot satisfy the machining requirements of difficult-to-machine materials with high hardness,high strength,and strong wearing resistance.Although superhard abrasives can machine the above-mentioned materials,their dressing and manufacturing costs are high.By contrast,ceramic corundum abrasives fabricated by sol–gel method is a costeffective product between conventional and superhard abrasives.Ceramic corundum abrasives exhibit self-sharpening and high toughness.In this review,the optimization methods of ceramic corundum abrasive properties are introduced from three aspects:precursor synthesis,particle shaping,and sintering.Firstly,the functional mechanism of seeds and additives on the microstructural and mechanical properties of abrasives is analyzed.Specifically,seeds can reduce the phase transition temperature and improve fracture toughness.The grain size and uniformly dense structure can be controlled by applying an appropriate amount of multicomponent additives.Then,the urgent need of engineering application and machinability of special shape ceramic corundum abrasives is reviewed,and three methods of abrasive shaping are summarized.The micromold replication technique is highly advanced and can be used to prepare functional abrasives.Additionally,the influence of a new sintering method,namely,two-step sintering technique,on the microstructural and mechanical performance of ceramic corundum abrasives is summarized.Finally,the challenge and developmental trend of the optimization of ceramic corundum abrasives are prospected. | Baoteng HUANG Changhe LI Yanbin ZHANG Wenfeng DING Min YANG Yuying YANG Han ZHAI Xuefeng XU Dazhong WANG Sujan DEBNATH Muhammad JAMIL Hao Nan Li Hafiz Muhammad ALI Munish Kumar GUPTA Zafar SAID | 2021 | Chinese Journal of Aeronautics2021，34，6： | 11 |
| 16 | Preliminary investigation on the antibacterial activity of mango(Mangifera indica L:Anacardiaceae) seed kernel显示文摘Objective:To evaluate the antibacterial activity of the methanolic extract of mango(Mangifera indica L) seed kernel.Methods:Chokanan mango seed kernel and seed kernels from assorted mango varieties were collected,cleaned,dried and powered.Crude methanolic extracts of mango seed kernel were analyzed for the phytochemical constituents.The free radical scavenging activity was determined by 2,2-Diphenyl-1-picrylhydrazyl(DPPH) assay.Antibacterial activity was evaluated by disc diffusion assay with three medically important bacterial pathogens such as methicillin resistant Staphylococcus aureus(S.aureus)(MRSA),Escherichia coli(E.coli) and Vibrio vulnificus(V.vulnificus).Results:Qualitative phytochemical analysis indicated the presence of important phytochemical compounds such as glycosides,saponins,flavanoids, tannins and alkaloids.There was no significant difference in the phytochemical content between the single and assorted mango seed kernels.However,the free radical scavenging study indicated that the assorted mango kernels showed slighdy higher activity than the single species(P<0.05). The crude methanolic extract of mango seed kernel at a concentration of 100 mg/mL is found to have potential antimicrobial activity against MRSA and E.coli compared to V.vulnificus. Study on the antibacterial activity also indicated that there was no significant difference in the antibacterial activity of the single and assorted mango seed kernel extracts.Conclusions:The present study conclusively demonstrates the free radical scavenging activity and antibacterial activities of mango seed kernel.In addition,the results also indicated that there is no significant difference in the phytochemical content and biological activity of mango kernels from single and assorted mango varieties. | Jasminder Kaur Xavier Rathinam Marimuthu Kasi Khoo Miew Leng Rajasekaran Ayyalu Kathiresan S Sreeramanan Subramaniam | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，9： | 11 |
| 17 | Role of endogenous hormones,glumes,endosperm and temperature on germination of Leymus chinensis(Poaceae)seeds during development显示文摘Aims Leymus chinensis is an original dominant plant in the Songnen grassland,and it has great value for restoration of severely degraded land.However,seeds are dormant,and low germination percentage is a problem for restoring L.chinensis grassland.The mechanism of seed dormancy is not been well understood.The primary aims of the present study were to investigate the dormancy mechanism of L.chinensis seeds(caryopses)with reference to the role of embryo-covering layers,endogenous hormones and temperature.Methods Changes in concentration of the endogenous hormones GA3,indoleacetic acid(IAA),zeatin riboside(ZR)and abscisic acid(ABA)in L.chinensis seeds fromanthesis to maturity weremeasured by the enzymelinked immunosorbent assay method.Germination at different stages of maturity were tested at 16/28C,5/28C and 5/35C for intact seeds with glumes(control),intact seeds with glumes removed(nakedwhole seeds)and intact seeds with glumes and one-half of the endosperm removed(naked-half seeds).Important Findings Of the four endogenous hormones monitored,only the concentration of ZR differed significantly between the beginning and the end of seed development(increased);the GA3/ABA ratio also did not differ.Rank of germination percentage of control at the three temperature regimens was 5/28C>16/28C>5/35C.Germination percentage of the naked-half seeds reached 100%under the three temperature regimens.We concluded that dormancy of L.chinensis seeds is not mainly controlled by endogenous hormones.Germination temperature,mechanical resistance of glumes and inhibition of endosperm are the main factors controlling dormancy and germination of L.chinensis seeds. | Hongyuan Ma Zhengwei Liang Haitao Wu Lihua Huang Zhichun Wang | 2010 | Journal of Plant Ecology2010，3，4： | 11 |
| 18 | A seed-specific AP2-domain transcription factor from soybean plays a certain role in regulation of seed ger-mination显示文摘Plant seed development and germination are under strict temporal and spatial regulation, and tran-scription factors play important roles in this regulation. In the present study we identified an EST ex-pressed specifically in the developing soybean seeds. The full length of the gene was obtained through further RACE analysis and the gene was named GmSGR. Sequence analysis revealed that this gene belonged to the AP2/ERF transcription factor family. Its AP2 domain had the highest similarity with that of the A-3 member AtABI4 of DREB subgroup in the AP2/ERF family in Arabidopsis. GmSGR did not exhibit transcriptional activation activity in the yeast assay system. GmSGR was overexpressed in Arabidopsis and the germination rates of the transgenic seeds were significantly higher than that of the wild type seeds under higher concentrations of ABA and glucose respectively. However, the germina-tion rates of the transgenic seeds were lower than that of control under salt stress. The expression of AtEm6 and AtRD29B was higher in the seedlings of the transgenic plants than that in the wild-type seedlings. These results suggest that GmSGR may confer reduced ABA sensitivity and enhanced salt sensitivity to the transgenic seeds through regulating the expression of AtEm6 and AtRD29B genes. | WANG ChunMei, WANG HuiWen, ZHANG JinSong & CHEN ShouYi National Key Laboratory of Plant Genomics, Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, Bei-jing 100101, China | 2008 | Science China(Life Sciences)2008，51，4： | 11 |
