| 2 | Bioaccumulation and translocation of cadmium in cole (Brassica campestris L.) and celery (Apium graveolens) grown in the polluted oasis soil,Northwest of China显示文摘A pot experiment was conducted to study the bioaccumulation and translocation of cadmium (Cd) in cole (Brassica campestris L.) and celery (Apium graveolens) grown in the Cd-polluted oasis soil,Northwest of China.The results showed that Cd in the unpolluted oasis soil was mainly bound to carbonate fraction (F2) and Fe-Mn oxide fraction (F3).However,marked change of Cd fractions was observed with increasing soil Cd concentrations,in which the concentration of Cd in F1 (exchangeable fraction),F2 and F3 increased significantly (p<0.001 for F1,F2 and F3).The growth of cole and celery could be facilitated by low concentrations of Cd,but inhibited by high concentrations.The correlation analysis between the fraction distribution coefficient of Cd in the soil and Cd concentration accumulated in the two vegetables showed that Cd in F1 in the soil made the greatest contribution on the accumulation of Cd in the two vegetables.The high bio-concentration factor and the translocation factor of Cd in both cole and celery were observed,and Cd had higher accumulation in the edible parts of the two vegetables.Therefore,both cole and celery grown in Cd-polluted oasis soil have higher risk to human health.And the two vegetables are not suitable to be cultivated as vegetables consumed by human in the Cd-polluted oasis soil. | Yiming Yang Zhongren Nan Zhuanjun Zhao Zhaowei Wang Shengli Wang Xia Wang Wangqiang Jin Cuicui Zhao | 2011 | Journal of Environmental Sciences2011，23，8： | 8 |
| 3 | Potato absorption and phytoavailability of Cd, Ni, Cu, Zn and Pb in sierozem soils amended with municipal sludge compost显示文摘Effects of sludge utilization on the mobility and phytoavailability of heavy metals in soil-plant systems have attracted broad attention in recent years. In this study, we analyzed the effects of municipal sludge compost(MSC) on the solubility and plant uptake of Cd, Ni, Cu, Zn and Pb in a soil-potato system to explore the mobility, potato plant uptake and enrichment of these five heavy metals in sierozem soils amended with MSC through a potato cultivation trial in Lanzhou University of China in 2014. Ridge regression analysis was conducted to investigate the phytoavailability of heavy metals in amended soils. Furthermore, CaCl_2, CH_3 COONH_4, CH_3COOH, diethylene triamine pentacetic acid(DTPA) and ethylene diamine tetraacetic acid(EDTA) were used to extract the labile fraction of heavy metals from the amended soils. The results show that the MSC could not only improve the fertility but also increase the dissolved organic carbon(DOC) content of sierozem soils. The total concentrations and labile fraction proportions of heavy metals increase with increasing MSC percentage in sierozem soils. In amended soils, Cd has the highest solubility and mobility while Ni has the lowest solubility and mobility among the five heavy metals. The MSC increases the concentrations of heavy metals in the root, stem, peel and tuber of the potato plant, with the concentrations being much higher in the stem and root than in the peel and tuber. Among the five heavy metals, the bioconcentration factor value of Cd is the highest, while that of Ni is the lowest. The complexing agent(DTPA and EDTA) extractable fractions of heavy metals are the highest in terms of phytoavailability. Soil properties(including organic matter, p H and DOC) have important impacts on the phytoavailability of heavy metals. Our results suggest that in soil-potato systems, although the MSC may improve soil fertility, it can also increase the risk of soils exposed to heavy metals. | LIU Zheng NAN Zhongren ZHAO Chuanyan YANG Yang | 2018 | Journal of Arid Land2018，10，4： | 4 |
| 4 | Cloning and Functional Analysis of the MADS-box CiMADS9 Gene from Carya illinoinensis显示文摘A MADS-box gene,CiMADS9,was cloned from the male flowers of Carya illinoinensis by rapid amplification of cDNA ends. The gene was 1 077 bp with a 768 bp open reading frame encoding 255 amino acids. Multiple sequence comparisons revealed that Ci MADS9 is a typical MIKC-type MADS-box gene with a MADS-box domain and a K semi-conserved region. Phylogenetic analysis indicated that CiMADS9 belongs to the AGL15 group of the MADS-box gene family. Quantitative reverse transcription polymerase chain reaction analysis indicated that the expression levels in reproductive organs(i.e.,flowers and young fruits) were considerably higher than in vegetative tissues(i.e.,leaves and branches). The highest expression levels were observed in male flowers. An overexpression vector for CiMADS9 was constructed and the gene was inserted into the Arabidopsis thaliana genome. CiMADS9 expression was confirmed in all transgenic lines. Compared with wild-type plants,transgenic A. thaliana plants overexpressing CiMADS9 exhibited delayed flowering and an increased number of leaves. | ZHANG Jiyu MO Zhenghai LI Yongrong WANG Gang XUAN Jiping JIA Xiaodong GUO Zhongren QIAN Meihua | 2015 | Horticultural Plant Journal2015，1，1： | 3 |
| 5 | A PSO-SVM Model for Short-Term Travel Time Prediction Based on Bluetooth Technology显示文摘The accurate prediction of travel time along roadway provides valuable traffic information for travelers and traffic managers. Aiming at short-term travel time forecasting on urban arterials,a prediction model( PSOSVM) combining support vector machine( SVM) and particle swarm optimization( PSO) is developed. Travel time data collected with Bluetooth devices are used to calibrate the proposed model. Field experiments show that the PSO-SVM model 's error indicators are lower than the single SVM model and the BP neural network( BPNN) model. Particularly,the mean-absolute percentage error( MAPE) of PSO-SVM is only 9. 453 4 %which is less than that of the single SVM model( 12. 230 2 %) and the BPNN model( 15. 314 7 %). The results indicate that the proposed PSO-SVM model is feasible and more effective than other models for shortterm travel time prediction on urban arterials. | Qun Wang Zhuyun Liu Zhongren Peng | 2015 | Journal of Harbin Institute of Technology(New Series)2015，22，3： | 3 |
| 6 | Endoscopic ultrasound-guided fine-needle aspiration for the diagnosis of pancreatic cysts by combined cytopathology and cystic content analysis显示文摘Recent advances in imaging technology have resulted in an increase in incidental discoveries of pancreatic cystic lesions. Pancreatic cysts comprise a wide variety of lesions and include non-neoplastic cysts and neoplastic cysts. Because some pancreatic cysts have more of a malignant potential than others, it is absolutely essential that an accurate diagnosis is rendered so that effective care can be given to each patient. In many centers, endoscopic ultrasound(EUS)-guided fine-needle aspiration(FNA) has emerged as the modality of choice that enables one to distinguish between mucinous and non-mucinous lesion, diagnose malignancy and collect cyst fluid for further diagnostic studies, such as pancreatic enzyme levels, molecular analysis and other tumor biomarkers. The current review will focus on EUSguided FNA and the cytological diagnosis for pancreatic cysts. | Amanda K Martin Zhongren Zhou | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，15： | 3 |

| 9 | Chemical fractionations and bioavailability of cadmium and zinc to cole (Brassica campestris L.) grown in the multi-metals contaminated oasis soil,northwest of China显示文摘A pot experiment was conducted to study the relationship between distribution of cadmium (Cd) and zinc (Zn) and their availability to cole (Brassica campestris L.) grown in the multi-metal contaminated oasis soil in northwest of China.The results showed that Cd and Zn in the unpolluted oasis soil was mainly found in the residual fractionation,however,with increasing contents of Cd and Zn in the oasis soil,the distribution of Cd and Zn changed significantly.The growth of cole could be promoted by low Cd and Zn concentration,but significantly restrained by high concentrations.There was antagonistic effect among Cd and Zn in the multi-metals contaminated oasis soil.Stepwise regression analysis between fractionations distribution coefficients of the two meals in the soil and their contents in cole showed that both Cd and Zn in the exchangeable fractionation in the oasis soil made the most contribution on the uptake of Cd and Zn in cole.The bio-concentration factor (BCF) of Cd was greater than Zn in cole,and BCFs of the two metals in leaves were greater than those in roots.The translocation factors of the two metals in cole were greater than 1,and the two metals mainly accumulated in the edible parts in cole.Therefore,cole is not a suitable vegetable for the oasis soil because of the plants notable contamination by heavy metals. | Yiming Yang Zhongren Nan Zhuanjun Zhao Shengli Wang Zhaowei Wang Xia Wang | 2011 | Journal of Environmental Sciences2011，23，2： | 2 |
| 10 | Interaction between Cd and Pb in the soil-plant system: a case study of an arid oasis soil-cole system显示文摘The Hexi Corridor,our study area,is located in Northwest China and is also the most developed area of oasis farming in arid regions of Northwestern China.However,the rapid development of metallurgy and chemical industries in this region poses a great threat to the accumulation of heavy metals in crops.The objectives of this study are(1)to determine the influence of heavy metals on plant growth;(2)to assess the translocation capability of heavy metals in soil-plant system;and(3)to investigate the interaction between heavy metals.Pot experiments were conducted on cole(Brassica campestris L.)grown in the arid oasis soils singly and jointly treated with cadmium(Cd)and lead(Pb).Nine treatments were applied into the pots.Under the same planting conditions,three scenarios of Cd,Pb and Cd–Pb were designed to compare the interaction between Cd and Pb.The results showed that the response of cole weights to Cd,Pb and Cd–Pb treatments was slight,while Cd and Pb uptakes in cole were more sensitive to the single effects of Cd and Pb concentration in soils from the lower treatment levels.Under the influence of the single Cd,Pb and joint Cd–Pb treatments,Cd concentrations were lower in the cole roots than in the shoots,while for Pb,the results were opposite.Comparison studies revealed that the interaction of Cd and Pb could weaken the cole’s ability to uptake,concentrate and translocate heavy metals in arid oasis soils. | ZhuanJun ZHAO ZhongRen NAN ZhaoWei WANG YiMing YANG Masayuki SHIMIZU | 2014 | Journal of Arid Land2014，6，1： | 2 |

| 13 | Comparative population genomics dissects the genetic basis of seven domestication traits in jujube显示文摘Jujube(Ziziphus jujuba Mill.)is an important perennial fruit tree with a range of interesting horticultural traits.It was domesticated from wild jujube(Ziziphus acidojujuba),but the genomic variation dynamics and genetic changes underlying its horticultural traits during domestication are poorly understood.Here,we report a comprehensive genome variation map based on the resequencing of 350 accessions,including wild,semi-wild and cultivated jujube plants,at a>15×depth.Using the combination of a genome-wide association study(GWAS)and selective sweep analysis,we identified several candidate genes potentially involved in regulating seven domestication traits in jujube.For fruit shape and kernel shape,we integrated the GWAS approach with transcriptome profiling data,expression analysis and the transgenic validation of a candidate gene to identify a causal gene,ZjFS3,which encodes an ethyleneresponsive transcription factor.Similarly,we identified a candidate gene for bearing-shoot length and the number of leaves per bearing shoot and two candidate genes for the seed-setting rate using GWAS.In the selective sweep analysis,we also discovered several putative genes for the presence of prickles on bearing shoots and the postharvest shelf life of fleshy fruits.This study outlines the genetic basis of jujube domestication and evolution and provides a rich genomic resource for mining other horticulturally important genes in jujube. | Mingxin Guo Zhongren Zhang Yanwei Cheng Sunan Li Peiyin Shao Qiang Yu Junjie Wang Gan Xu Xiaotian Zhang Jiajia Liu Linlin Hou Hanxiao Liu Xusheng Zhao | 2020 | Horticulture Research2020，7，1： | 2 |

| 16 | Expression and inhibitory activity analysis of a 25-kD Bowman-Birk protease inhibitor in rice显示文摘Rice Bowman-Birk inhibitors (RBBI), with one (8 kD) or two homologous domains (16 kD), were found to be effective trypsin inhibitors in vitro. In this study, we demonstrate that the 25-kD protein corresponding to the three-domain RBBI indeed ex- ists in rice in planta, and that the RBBIs are regulated by development and wounding. We also found by inhibitory activity assay that the 3:13 disulfide bond, but not the 4:5 disulfide bond, suppresses the tryp- sin-inhibitory activity, and the D3 domain of RBBI3-1 has no inhibitory activity against trypsin, chymotryp- sin, paparin or subtilisin. Mutation analyses showed that conversion from Lys to Leu or Tyr in the N-terminal P1 site in D1 domain did not create chy- motrypsin-inhibitory activity, suggesting that the structure of the reactive loop in D1 domain hinder the new inhibitory specificity at P1 site, and the chy- motrypsin-inhibitory activity might need the participa- tion of other structures, e.g. 3:13 disulfide bond. | CHEN Jun MAO Shengji XlE Yang CAO Zhongren ZHANG Yan LIU jing CHEN Zhangliang QU Lijia GU Hongya | 2006 | Chinese Science Bulletin2006，51，1： | 2 |
