| 1 | Long-term trend and abrupt events of the Holocene Asian monsoon inferred from a stalagmiteδ^(18)O record from Shennongjia in Central China显示文摘A high-resolution oxygen-isotope record from a thorium-uranium-dated stalagmite from Shanbao Cave at Shennongjia reflects variations in the amount of monsoon precipitation for the period from 11.5 to 2.1 ka (1 ka = 1000 cal aBP). Between 11.5 and 9.3 ka, a sharp decrease in δ18O indicates a rapid increase in monsoon precipitation. An interval of generally high monsoon precipitation is observed between 9.3 and 4.4 ka. An arid period has prevailed between 4.4 and 2.1 ka. The long-term trend of Shanbao record appears to follow summer insolation at 33°N latitude. An abrupt decrease in monsoon precipitation around 4.3 ka is synchronous with the collapse of Neolithic culture in central China. This abrupt change could have resulted from the amplifi- cation of the gradually decreased summer insolation by the positive vegetation-atmosphere-aerosol feed- back. The weakened Asian monsoon events were in concert with decreased Greenland temperature dur- ing the early Holocene, centered at 8.2, 8.6, 9.3, 10.2 and 11.0 ka. This correlation suggests that changes in low-latitude monsoon are connected with climate change in high-latitude polar region. | SHAO Xiaohua WANG Yongjin CHENG Hai KONG Xinggong WU Jiangying EDWARDS R.

| 2 | Effects of Transgenic Tobacco Plants Expressing ACA Gene from Amaranthus caudatus on the Population Development of Myzus persicae显示文摘To investigate the possible function of the agglutinin from Amaranthus caudatus L. (ACA) in plant defending against insect pests, ACA cDNA was cloned by RT-PCR and the 5' and 3' sequences were confirmed by rapid amplification of cDNA ends (RACE). The phloem-specific expression vector of ACA gene, pBCACAc, was constructed based on the plant binary vector pBC438 and transfered into tobacco plants via Agrobacterium-mediated transformation method. Results from PCR and Southern blotting analysis showed that AOA gene was integrated into the genomes of transformed plants and the transgene integration varied from one to four estimated copies per genome. Western blotting analysis indicated that ACA gene was transcribed and translated in the transgenic plants. The bioassay of Myzus persicae Sulzer on detached leaves demonstrated that the 78% transgenic tobacco plants displayed an average aphid-resistant rate of more than 75%. Some apterous progeny of M. persicae were found dead on the resistant plants. These results indicate that ACA gene should be an effective aphid-resistant gene and could be valuable for application in crop breeding for aphid resistance. | GUOHong-Nian JIAYan-Tao ZHOUYong-Gang ZHANGZhen-Shan OUYANGQing JIANGYing TIANYing-Chuan | 2004 | Acta Botanica Sinica2004，46，9： | 12 |
| 3 | Abrupt climate change of EastAsian Monsoon at 130 kaBP inferred from a high resolu-tion stalagmite δ^(18)O record显示文摘230Th ages and oxygen isotope data of a stalagmite from Shanbao Cave in Hubei Province characterize thEast Asian Monsoon precipitation from 133 to127 ka. Thdecadal-scale high-resolution δ18O record reveals a detailedtransitional process from the Penultimate Glaciation to thLast Interglaciation. As established with 230Th dates, the agof the Termination II is determined to be 129.5±1.0 kaBPwhich supports the Northern Hemisphere insolation as thtriggers for the ice-age cycles. In our δ18O record, the glacialinterglacial fluctuation reaches about 4‰, almost the samlevel as in other Asian Monsoon cave stalagmite δ18O recordThe transition of the glacial/interglacial period in our recordcan be recognized as four stepwise stages, among which, arapid rise of monsoon precipitation follows the stage o“Termination II pause”. The rapid rise is synchronous withthe abrupt change of global methane concentration, whichreflects that an increase in both Asian Monsoon precipitationand tropical wetland plays an important role in the globaclimate changes. | JIANG Xiuyang WANG Yongjin KONG Xinggong WU Jiangying SHAO Xiaohua XIA Zhifeng CHENG Hai | 2005 | Chinese Science Bulletin2005，50，23： | 9 |
| 4 | A high-resolution stalagmite O-C isotope record from Nanjing and its rapid response to climatic events显示文摘Here we discussed rapid response of the cave temperature and vegetation to the four Dansgaard-Oeschger cold and warm cycles during 50-40 kaBP based on results of oxygen and carbon stable isotopic compositions from a stalagmite in Tangshan, Nanjing. It is found that the amount of C3 vegetation relative to C4-type declines during the D-O warm events, indicating the decrease of the effective mete-oric precipitation. Compared with O-isotope records of the Greenland ice core, the stalagmite record displays a very similar pattern to Greenland ice core record over the dec-ade-century time scale, suggesting that the changes of the East Asian monsoon climate are in accordance with the high-latitude polar climate in the short-term time scale. The age of the ice-rafted H5 event in the stalagmite record, how-ever, preceded that of Greenland ice cores by 2 ka. This out of phase between the remote areas cannot be yet proven be-cause the two time scales were determined from different dating methods. | WU Jiangying WANG Yongjin CHENG Hai CHEN Jun | 2002 | Chinese Science Bulletin2002，47，2： | 7 |
| 5 | IMPRINT OF SOLAR ACTIVITY ON NANJING STALAGMITE ANNUAL LAYER THICKNESS SEQUENCE DURING THE LAST GLACIAL MAXIMUM显示文摘A 3000-year-long stalagmite chronology from Hulu Cave near Nanjing was established by counting annual layers under microscope. Based on the 230Th age, this chronology covers the period 24-21 kaBP, within the Last Glacial Maximum (LGM). Two proxies, annual layer thickness and gray level were measured along the growth axis of the stalag-mite profile in order to establish a high-resolution East Asian monsoon history during the LGM. The high correlation coefficient (r = 0.55) between the two proxies suggests that both of them were controlled by a common factor, possibly reflecting changes in the strength of summer monsoon circulation and its pre-cipitation. Low frequency variations of the annual layer thickness, ranging from centennial to millennial scales, are approximately in agreement with the 10Be-flux recorded in the Greenland ice core, indi-cating that changes in East Asian monsoon strength might be forced by solar outputs during the LGM pe-riods. In support of this, Fourier power spectrum analysis of the annual layer thickness showed certain decadal to centennial-scale cycles that agree well with the periodicities of solar activity. | WU Jiangying SHAO Xiaohua KONG Xinggong WANG Yongjin | 2006 | Chinese Science Bulletin2006，51，4： | 5 |

| 7 | Roles of pre-formed martensite in below-Ms bainite formation,microstructure,strain partitioning and impact absorption energies of low-carbon bainitic steel显示文摘The roles of pre-formed martensite(PM)in below-Ms bainite formation,microstructure,crystallography,strain partitioning and mechanical properties of a low-carbon bainitic steel were investigated using electron-backscattered diffraction,transmission electron microscopy,micro digital image correlation technique and mechanical tests.It is demonstrated that the pre-formation of martensite eliminates the incubation time for bainite transformation at various austempering temperatures below Ms,indicative of its acceleration effect at the early stage of transformation.This effect is mainly attributed to the surfaces or tips of the PM acting as the nuclei of subsequently-formed bainite,with initial bainite tending to form around the PM.However,the finishing time for below-Ms bainite transformation,especially at even lower temperatures,is retarded,owing to the dividing effect of PM on parent austenite grains,the decreasing effect of lowered isothermal temperature on the diffusion rate of carbon atoms and the strengthening effect of lowered isothermal temperature on supercooled austenite.PM and its adjacent bainitic laths have nearly the same crystallographic orientation and belong to the same block.The pre-formation of martensite largely refines the bainitic blocks/laths and retained austenite.The specimens with PM show relatively uniform strain partitioning among various phases,contrasting with the specimens without PM,for which strains are highly concentrated in the bainite region nearby fresh martensite/austenite(M/A)blocks or between adjacent M/A blocks.The impact absorption energies of the specimens with PM,when austempered at 30-60℃ below Ms,are more than twice higher than those of the specimens without PM,at no expense of tensile properties. | Lihe Qian Zhi Li Tongliang Wang Dongdong Li Fucheng Zhang Jiangying Meng | 2022 | Journal of Materials Science & Technology2022，，1： | 4 |
| 8 | A new loss-of-function allele 28y reveals a role of ARGONAUTE1 in limiting asymmetric division of stomatal lineage ground cell显示文摘In Arabidopsis thaliana L., stomata are produced through a series of divisions including asymmetric and symmetric divisions. Asymmetric entry division of meristemoid mother cell produces two daughter cells, the smaller meristemoid and the larger sister cell, a stomatal lineage ground cell(SLGC). Stomatal lineage ground cells can differentiate into epidermal pavement cells but have the potential to divide asymmetrically, spacing divisions, to create satellite meristemoids. Peptide ligands and TOO MANY MOUTHS(TMM) and ERECTA family receptors regulate the initiation of stomatal lineages, activity, and orientation of spacing divisions. Here, we reported that a natural mutant 28 y displayed an increased stomatal density and index. Using map-based cloning, we identified mutation in ARGONAUTE1(AGO1)as the cause of 28 y phenotypes. Time-lapse tracing of stomatal lineage cells reveals that stomatal overproduction in 28 y is caused by the excessive asymmetric spacing division of SLGCs.Further genetic results demonstrated that AGO1 acts downstream of TMM and negatively regulates the SPCH transcripts,but in a brassinosteroid-independent manner. Upregulation of AGAMOUS-LIKE16(AGL16) in 28 y mutants suggests that AGO1 is required to restrict AGL16-mediated stomatal spacing divisions,an miRNA pathway in addition to ligand-receptor signaling modules. | Kezhen Yangy Min Jiangy Jie Le | 2014 | Journal of Integrative Plant Biology2014，56，6： | 3 |

| 12 | Nogo-A and Nogo-A receptor expression in periventricular white matter of experimental autoimmune encephalomyelitis rats显示文摘BACKGROUND:Previous studies have focused on the correlation between Nogo-A expression and multiple sclerosis or between Nogo-A receptor(NgR) expression and multiple sclerosis in the central nervous system.Expression patterns of Nogo-A and NgR remain poorly understood in rat models of experimental autoimmune encephalomyelitis(EAE).OBJECTIVE:To observe dynamic changes in Nogo-A and NgR protein expression,and to verify the correlation between Nogo-A and NgR protein,as well as expression patterns at various time points,in periventricular tissue of EAE rats.DESIGN,TIME AND SETTING:A neuroimmunological,randomized,controlled experiment was performed at the Clinical Institute of Hunan People's Hospital of China from September to November 2008.MATERIALS:Immunohistochemistry(streptavidin-biotin-peroxidase complex method) kit was purchased from Boster,China.METHODS:A total of 60 female,Wistar rats,aged 6-8 weeks,were randomly assigned to EAE and control groups(n = 30,respectively).Guinea pig spinal cord homogenate,self-made complete Freund's adjuvant(0.2 mL/100 g),and pertussis vaccine(0.2 mL) were subcutaneously injected into the hindlimb foot pad of rats from the EAE group to create rat models of EAE.Complete Freund's adjuvant(0.2 mL) was infused into rats from the control group.MAIN OUTCOME MEASURES:Nogo-A and NgR protein expression was determined in periventricular white matter using immunohistochemical methods.Neurological scores were determined in all rats.RESULTS:Rats from the EAE group developed acute-onset EAE following immunization.The pathogenetic symptoms reached a peak on day 15,and neurological scores were also greatest at this time point.Neurological scores decreased with recovery of the illness.Nogo-A was shown to be expressed in neuronal cells and oligodendrocytes,and expression increased 11 days after immunization(P < 0.01),decreased by day 13(P < 0.01),and then increased again by day 15.Nogo-A expression remained greater in the EAE group compared with the control group at day 30(P < 0.01).In the EAE group,NgR protein was primarily expressed on the surface of neuronal bodies and axons.NgR expression increased 13-18 days after immunization(P < 0.01 or P < 0.05).CONCLUSION:Nogo-A and NgR protein expression altered with disease course in periventricular white matter of EAE rats.Results suggested that Nogo-A and NgR were involved in EAE occurrence. | Liming Tan Ying Chi Chunyu Wang1, Jun Wu1, Hainan Zhang1, Xiangmin Shen1, ShujuanDuan1, Bo JiangI Jun Wu Hainan Zhang Xiangmin Shen Shujuan Duan Bo Jiang | 2010 | Neural Regeneration Research2010，5，8： | 2 |
| 13 | Peroxidase from foxtail millet bran exerts anticolorectal cancer activity via targeting cellsurface GRP78 to inactivate STAT3 pathway显示文摘Molecular targeted therapy has become an emerging promising strategy in cancer treatment,and screening the agents targeting at cancer cell specific targets is very desirable for cancer treatment.Our previous study firstly found that a secretory peroxidase of class III derived from foxtail millet bran(FMBP)exhibited excellent targeting anti-colorectal cancer(CRC)activity in vivo and in vitro,whereas its underlying target remains unclear.The highlight of present study focuses on the finding that cell surface glucose-regulated protein 78(cs GRP78)abnormally located on CRC is positively correlated with the anti-CRC effects of FMBP,indicating it serves as a potential target of FMBP against CRC.Further,we demonstrated that the combination of FMBP with the nucleotide binding domain(NBD)of cs GRP78interfered with the downstream activation of signal transducer and activator of transcription 3(STAT3)in CRC cells,thus promoting the intracellular accumulation of reactive oxygen species(ROS)and cell grown inhibition.These phenomena were further confirmed in nude mice tumor model.Collectively,our study highlights cs GRP78 acts as an underlying target of FMBP against CRC,uncovering the clinical potential of FMBP as a targeted agent for CRC in the future. | Shuhua Shan Jinping Niu Ruopeng Yin Jiangying Shi Lizhen Zhang Caihong Wu Hanqing Li Zhuoyu Li | 2022 | Acta Pharmaceutica Sinica B2022，12，3： | 2 |
| 14 | Disease-tolerance of transgenic tobacco plants expressing Ah-AMP gene of Amaranthus hypochondriacus显示文摘An antimicrobial peptide gene from Amaranthus hypochondriacus, Ah-AMP, was amplified by PCR and cloned. Sequence analysis results revealed that this gene is 261 bp in length encoding a precursor polypeptide of 87 amino acid residues. Ah-AMP gene was inserted in the binary vector pBin438 to construct a plant expression vector pBinAH916. Leave explants of Nicotiana tabacum var. SR1 were transformed with Agrobacterium tumefaciens LBA4404 harboring the above expression vector. Results from PCR, Southern and Northern blot analyses confirmed that the Ah-AMP gene had been integrated into the tobacco genome and was transcribed at mRNA level. Two bacterial-resistant transgenic plants were selected by inoculating the plants with Pseudomonas solanacearum and statistic analysis of two T1 lines showed that the resistance increased by 2.24 and 1.62 grade and the disease index decreased by 49.6% and 37.3% respectively when compared with the non-transformed control plants SR1. The results from challenging the plants with inoculums of Phytophthora parasitica showed that the symptom development was delayed and disease index was significantly reduced. These results suggest that Ah-AMP gene may be a potentially valuable gene for genetic engineering of plant for disease-resistance. | CHENYan GUOHongnian JIANGYing LIChangqing ZHAOWenming TIANYingchuan | 2003 | Progress in Natural Science:Materials International2003，13，5： | 2 |
