1Identification of plasma microRNA-21 as a biomarker for early detection and chemosensitivity of non-small cell lung cancer显示文摘Studies have shown cell-free microRNA(miRNA) circulating in the serum and plasma with specific expression in cancer,indicating the potential of using miRNAs as biomarkers for cancer diagnosis and therapy.This study was to investigate whether plasma miRNA-21(miR-21) can be used as a biomarker for the early detection of non-small cell lung cancer(NSCLC) and to explore its association with clinicopathologic features and sensitivity to platinum-based chemotherapy.We used real-time RT-PCR to investigate the expression of miR-21 in the plasma of 63 NSCLC patients and 30 healthy controls and correlated the findings with early diagnosis,pathologic parameters,and treatment.Thirty-five patients(stages IIIB and IV) were evaluable for chemotherapeutic responses:11 had partial response(PR);24 had stable and progressive disease(SD+PD).Plasma miR-21 was significantly higher in NSCLC patients than in age-and sex-matched controls(P<0.001).miR-21 was related to TNM stage(P<0.001),but not related to age,sex,smoking status,histological classification,lymph node status,and metastasis(all P>0.05).This marker yielded a receiver operating characteristic(ROC) curve area of 0.775(95% CI:0.681-0.868) with 76.2% sensitivity and 70.0% specificity.Importantly,miR-21 plasma levels in PR samples were several folds lower than that in SD plus PD samples(P=0.049),and were close to that in healthy controls(P=0.130).Plasma miR-21 can serve as a circulating tumor biomarker for the early diagnosis of NSCLC and is related to the sensitivity to platinum-base chemotherapy.Juan Wei Wen Gao Cheng-Jun Zhu Yi-Qian Liu Zhu Mei Ting Cheng Yong-Qian Shu 2011Chinese Journal of Cancer2011,30,6:63
2The Reference Genome of Tea Plant and Resequencing of 81 Diverse Accessions Provide Insights into Its Genome Evolution and Adaptation显示文摘Tea plant is an important economic crop,which is used to produce the world's oldest and most widely consumed tea beverages.Here,we present a high-quality reference genome assembly of the tea plant(Camellia sinensis var.sinensis)consisting of 15 pseudo-chromosomes.LTR retrotransposons(LTR-RTs)account for 70.38%of the genome,and we present evidence that LTR-RTS play critical roles in genome size expansion and the transcriptional diversification of tea plant genes through preferential insertion in promoter regions and introns.Genes,particularly those coding for terpene biosynthesis pro-teins,associated with tea aroma and stress resistance were significantly amplified through recent tandem duplications and exist as gene clusters in tea plant genome.Phylogenetic analysis of the sequences of 81 tea plant accessions with diverse origins revealed three well-differentiated tea plant populations,support-ing the proposition for the southwest origin of the Chinese cultivated tea plant and its later spread to western Asia through introduction.Domestication and modern breeding left significant signatures on hundreds of genes in the tea plant genome,particularly those associated with tea quality and stress resis-tance.The genomic sequences of the reported reference and resequenced tea plant accessions provide valuable resources for future functional genomics study and molecular breeding of improved cul-tivars of tea plants.Enhua Xia Wei Tong Yan Hou Yanlin An Linbo Chen Qiong Wu Yunlong Liu Jie Yu Fangdong Li Ruopei Li Penghui Li Huijuan Zhao Ruoheng Ge Jin Huang Ali Inayat Mallano Yanrui Zhang Shengrui Liu Weiwei Deng Chuankui Song Zhaoliang Zhang Jian Zhao Shu Wei Zhengzhu Zhang Tao Xia Chaoling Wei Xiaochun Wan 2020Molecular Plant2020,13,7:51
3Diagnosis and treatment recommendations for pediatric respiratory infection caused by the 2019 novel coronavirus显示文摘Since December 2019,an epidemic caused by novel coronavirus (2019-nCoV) infection has occurred unexpectedly in China.As of 8 pm,31 January 2020,more than 20 pediatric cases have been reported in China.Of these cases,ten patients were identified in Zhejiang Province,with an age of onset ranging from 112 days to 17 years.Following the latest National recommendations for diagnosis and treatment of pneumonia caused by 2019-nCo V (the 4th edition) and current status of clinical practice in Zhejiang Province,recommendations for the diagnosis and treatment of respiratory infection caused by 2019-nCoV for children were drafted by the National Clinical Research Center for Child Health,the National Children's Regional Medical Center,Children's Hospital,Zhejiang University School of Medicine to further standardize the protocol for diagnosis and treatment of respiratory infection in children caused by 2019-nCoV.Zhi-Min Chen Jun-Fen Fu Qiang Shu Ying-Hu Chen Chun-Zhen Hua Fu-Bang Li Ru Lin Lan-Fang Tang Tian-Lin Wang Wei Wang Ying-Shuo Wang Wei-Ze Xu Zi-Hao Yang Sheng Ye Tian-Ming Yuan Chen-Mei Zhang Yuan-Yuan Zhang 2020World Journal of Pediatrics2020,16,3:45

5SlMYB75,an MYB-type transcription factor,promotes anthocyanin accumulation and enhances volatile aroma production in tomato fruits显示文摘Genetic manipulation of genes to upregulate specific branches of metabolic pathways is a method that is commonly used to improve fruit quality.However,the use of a single gene to impact several metabolic pathways is difficult.Here,we show that overexpression of the single gene SlMYB75(SlMYB75-OE)is effective at improving multiple fruit quality traits.In these engineered fruits,the anthocyanin content reached 1.86mg g−1 fresh weight at the red-ripe stage,and these SlMYB75-OE tomatoes displayed a series of physiological changes,including delayed ripening and increased ethylene production.In addition to anthocyanin,the total contents of phenolics,flavonoids and soluble solids in SlMYB75-OE fruits were enhanced by 2.6,4,and 1.2 times,respectively,compared to those of wild-type(WT)fruits.Interestingly,a number of aroma volatiles,such as aldehyde,phenylpropanoid-derived and terpene volatiles,were significantly increased in SlMYB75-OE fruits,with some terpene volatiles showing more than 10 times higher levels than those in WT fruits.Consistent with the metabolic assessment,transcriptomic profiling indicated that the genes involved in the ethylene signaling,phenylpropanoid and isoprenoid pathways were greatly upregulated in SlMYB75-OE fruits.Yeast one-hybrid and transactivation assays revealed that SlMYB75 is able to directly bind to the MYBPLANT and MYBPZM cis-regulatory elements and to activate the promoters of the LOXC,AADC2 and TPS genes.The identification of SlMYB75 as a key regulator of fruit quality attributes through the transcriptional regulation of downstream genes involved in several metabolic pathways opens new avenues towards engineering fruits with a higher sensory and nutritional quality.Wei Jian Haohao Cao Shu Yuan Yudong Liu Juanfang Lu Wang Lu Ning Li Jianhui Wang Jian Zou Ning Tang Chan Xu Yulin Cheng Yanqiang Gao Wanpeng Xi Mondher Bouzayen Zhengguo Li 2019Horticulture Research2019,6,1:39
6Prognostic value of preoperative serum tumor markers in gastric cancer显示文摘AIM:To evaluate the prognostic value of preoperative carcinoembryonic antigen(CEA), carbohydrate antigen(CA)19-9, and CA50 in patients undergoing D2 resection.METHODS:We evaluated 363 patients with gastric cancer who underwent gastrectomy at our hospital from January 2006 to December 2009. Blood samples were obtained from each patient within 1 wk before surgery. The cut-off values for serum CEA, CA19-9,and CA50 were 5 ng/mL, 37 U/mL, and 20 U/mL, respectively. The correlation between preoperative tumor marker levels and prognosis was studied by means of univariate and multivariate analyses.RESULTS:The preoperative serum positive rates of CEA, CA19-9 and CA50 were 24.0%, 18.9% and24.5%, respectively. The positivity rate of serum CEA was significantly correlated with age(P < 0.001), sex(P = 0.022), tumor size(P = 0.007) and depth of invasion(P = 0.018); CA19-9 with tumor size(P = 0.042)and lymph node metastasis(P < 0.001); and CA50 onlywith lymph node metastasis(P = 0.001). In multivariate analysis, tumor size, T category, N category, vascular or neural invasion, and adjuvant chemotherapy were independent prognostic factors for overall survival. CA19-9 had an independent prognostic significance in patients without adjuvant chemotherapy(P = 0.027).CONCLUSION:Preoperative serum CEA, CA19-9 and CA50 are prognostic in patients with gastric cancer. Only CA19-9 is an independent prognostic factor after surgery without adjuvant chemotherapy.Ze-Bo Huang Xin Zhou Jun Xu Yi-Ping Du Wei Zhu Jian Wang Yong-Qian Shu Ping Liu 2014World Journal of Clinical Oncology2014,5,2:30
7Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy.Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen 2021Cancer Communications2021,41,11:29
8The spatial distribution of forest carbon sinks and sources in China显示文摘Forest ecosystems play an important role in the global carbon cycle.The implementation of the United Nations Framework Convention on Climate Change(UNFCCC) and the Kyoto Protocol has made the study of forest ecosystem carbon cycling a hot topic of scientific research globally.This paper utilized Chinese national forest inventory data sets(for the periods 1984-1988 and 1999-2003),the vegetation map of China(1:1000000),and the spatially explicit net primary productivity(NPP) data sets derived with the remote sensing-based light use efficiency model(CASA model).We quantitatively estimated the spatial distribution of carbon sinks and sources of forest vegetation(with a resolution of 1 km) using the spatial downscaling technique.During the period 1984 to 2003 the forest vegetation in China represented a carbon sink.The total storage of carbon increased by 0.77 PgC,with a mean of 51.0TgCa 1.The total carbon sink was 0.88PgC and carbon source was 0.11 PgC during the study period.The carbon sink and carbon source of forest vegetation in China showed a clear spatial distribution pattern.Carbon sinks were mainly located in subtropical and temperate regions,with the highest values in Hainan Province,Hengduan mountain ranges,Changbai mountain ranges in Jilin,and south and northwest of the Da Hinggan Mountains;carbon sources were mainly distributed from the northeast to southwestern areas in China,with the highest values mainly concentrated in southern Yunnan Province,central Sichuan Basin,and northern Da Hinggan Mountains.Increase in NPP was strongly correlated with carbon sink strength.The regression model showed that more than 80% of the variation in the modeled carbon sinks in Northeast,Northern,Northwest and Southern China were explained by the variation in NPP increase.There was a strong relationship between carbon sink strength and forest stand age.LIU ShuangNa ZHOU Tao WEI LinYan SHU Yang 2012Chinese Science Bulletin2012,57,14:27
9Grenvillian orogeny in the Southern Cathaysia Block:Constraints from U-Pb ages and Lu-Hf isotopes in zircon from metamorphic basement显示文摘Metamorphic basement rocks in the Cathaysia Block are composed mainly of meta-sediments with different ages. New zircon U-Pb geochronological results from the meta-sedimentary rocks exposed in the Zengcheng and Hezi areas, southern Cathaysia Block, show that they consist dominantly of early Neoproterozoic (1.0―0.9 Ga) materials with minor Paleo- to Mesoproterozoic and late Neoproterozoic (0.8―0.6 Ga) components, suggesting that the detritus mostly come from a Grenvillian orogen. The youngest detrital zircon ages place a constraint on the deposition time of these sediments in Late Neoproterozoic. Zircon Hf isotopic compositions indicate that the Grenvillian zircons were derived from the reworking of Mesoproterozoic arc magmatic rocks and Paleoproterozoic continental crust, implying an arc-continent collisional setting. Single-peak age spectra and the presence of abundant euhedral Grenvillian zircons suggest that the sedimentary provenance is not far away from the sample location. Thus, the Grenvillian orogen probably preexisted along the southern margin of the Cathaysia Block, or very close to the south. Similarity in the ages of Grenvillian orogeny and the influence of the assembly of Gondwana in South China with India and East Antarctic are discussed, with suggestion that South China was more likely linked with the India-East Antarctica continents in Early Neoproterozoic rather than between western Laurentia and eastern Australia.WANG LiJuan YU JinHai S.Y.

10Large Scale Photochemical Synthesis of M@TiO_(2) Nanocomposites (M = Ag, Pd, Au, Pt) and Their Optical Properties, CO Oxidation Performance, and Antibacterial Effect显示文摘Well-dispersed M@TiO_(2)(M=Ag,Pd,Au,Pt)nanocomposite particles with a diameter of 200-400 nm can be synthesized on a large scale by a clean photochemical route which does not require any additives using spherical rutile nanoparticles as a support.The sizes of Pt,Au,and Pd nanoparticles formed on the surface of TiO_(2) particles are about 1 nm,5 nm,and 5 nm,respectively,and the diameter of Ag nanoparticles is in the range 2-20 nm.Moreover,the noble metal nanoparticles have good dispersity on the particles of the TiO_(2) support,resulting in excellent catalytic activities.Complete conversion in catalytic CO oxidation is reached at temperatures as low as 333 and 363 K,respectively,for Pt@TiO_(2) and Pd@TiO_(2) catalysts.In addition,the antibacterial effects of the as-synthesized TiO_(2) nanoparticles,silver nanoparticles,and Au@TiO_(2) and Ag@TiO_(2) nanocomposites have been tested against Gram-negative Escherichia coli(E.coli)bacteria.The results demonstrate that the presence of the TiO_(2) matrix enhances the antibacterial effect of silver nanoparticles,and the growth of E.coli can be completely inhibited even if the concentration of Ag in Ag@TiO_(2) nanocomposite is very low(10μg/mL).Shao Feng Chen Jian Ping Li Kun Qian Wei Ping Xu Yang Lu Wei Xin Huang Shu Hong Yu 2010Nano Research2010,3,4:20
11Numerical modeling and dynamic analysis of the 2017 Xinmo landslide in Maoxian County, China显示文摘A catastrophic landslide occurred at Xinmo village in Maoxian County, Sichuan Province,China, on June 24, 2017. A 2.87×106 m3 rock mass collapsed and entrained the surface soil layer along the landslide path. Eighty-three people were killed or went missing and more than 103 houses were destroyed. In this paper, the geological conditions of the landslide are analyzed via field investigation and high-resolution imagery. The dynamic process and runout characteristics of the landslide are numerically analyzed using a depth-integrated continuum method and Mac Cormack-TVD finite difference algorithm.Computational results show that the evaluated area of the danger zone matchs well with the results of field investigation. It is worth noting that soil sprayed by the high-speed blast needs to be taken into account for such kind of large high-locality landslide. The maximum velocity is about 55 m/s, which is consistent with most cases. In addition, the potential danger zone of an unstable block is evaluated. The potential risk area evaluated by the efficient depthintegrated continuum method could play a significant role in disaster prevention and secondary hazard avoidance during rescue operations.OUYANG Chao-jun ZHAO Wei HE Si-ming WANG Dong-po ZHOU Shu AN Hui-cong WANG Zhong-wen CHENG Duo-xiang 2017Journal of Mountain Science2017,14,9:19
12Survival of transplanted neurotrophin-3 expressing human neural stem cells and motor function in a rat model of spinal cord injury显示文摘<正>BACKGROUND:Many methods have been attempted to repair nerves following spinal cord injury, including peripheral nerve transplantation,Schwann cell transplantation,olfactory ensheathing cell transplantation,and embryonic neural tissue transplantation.However,there is a need for improved outcomes. OBJECTIVE:To investigate the repair feasibility for rat spinal cord injury using human neural stem cells(hNSCs) genetically modified by lentivirus to express neurotrophin-3. DESIGN,TIME AND SETTING:In vitro cell biological experiment and in vivo randomized,controlled, genetic engineering experiment were performed at the Third Military Medical University of Chinese PLA and First People's Hospital of Yibin,China from March 2006 to December 2007. MATERIALS:A total of 64 adult,female,Wistar rats were used for the in vivo study.Of them,48 rats were used to establish models of spinal cord hemisection,and were subsequently equally and randomly assigned to model,genetically modified hNSC,and normal hNSC groups.The remaining 16 rats served as normal controls. METHODS:hNSCs were in vitro genetically modified by lentivirus to secrete both green fluorescence protein and neurotrophin-3.Neurotrophin-3 expression was measured by Western blot. Genetically modified hNSC or normal hNSC suspension(5×10~5) was injected into the rat spinal cord following T_(10) spinal cord hemisection.A total of 5μL Dulbecco's-modified Eagle's medium was infused into the rat spinal cord in the model group.Transgene expression and survival of transplanted hNSCs were determined by immunohistochemistry.Motor function was evaluated using the Basso,Beattie,and Bresnahan(BBB) scale. MAIN OUTCOME MEASURES:The following parameters were measured:expression of neurotrophin-3 produced by genetically modified hNSCs,transgene expression and survival of hNSCs in rats,motor function in rats. RESULTS:hNSCs were successfully genetically modified by lentivirus to stably express neurotrophin-3.The transplanted hNSCs primarily gathered at,or around,the injection site two weeks following transplantation,and gradually migrated towards the surrounding tissue. Transplanted hNSCs were observed 7.0-8.0 mm away from the injection site.In addition,hNSCs were observed 10 weeks after transplantation.At week 4,BBB locomotor scores were significantly greater in the genetically modified hNSC and normal hNSC groups,compared with the model group (P<0.05),and scores were significantly greater in the genetically modified hNSC group compared with the normal hNSC group(P<0.05). CONCLUSION:hNSCs were genetically modified with lentivirus to stably secrete neurotrophin-3. hNSCs improved motor function recovery in rats following spinal cord injury.Peiqiang Cai Guangyun Sun Peishu Cai Martin Oudega Rui Xiao Xuewen Wang Wei Li Yunbing Shu Cheng Cai Haihao Yang Xuebing Shan Wuhua Luo 2009Neural Regeneration Research2009,4,7:18
13A Theoretical Framework and Methodology for Urban Activity Spatial Structure in E-society: Empirical Evidence for Nanjing City, China显示文摘The existing researches on the influence of information and communication technology(ICT) are mainly focused on human activity, whilst with few efforts on urban space. In the e-society, the widespread adoption of ICT devices not only affects almost every aspect of people′s daily life and thereby reshapes the spatial development of regions and cities, but also generates a large amount of real-time activity data with location information. These georeferenced data, however, have relatively recently attracted attention from geographers. Adapted from Lynch′s framework based on people′s perceptions, this paper proposes a framework of urban spatial structure based on people′s actual activity, including five elements, namely activity path, activity node, central activity zone(CAZ), activity district, and activity edge. In the empirical study, by using one week′s check-in tweets(from February 25 to March 3 in 2013) collected in Nanjing City, the five elements are recognized and analyzed. Through the comparison between our results and urban spatial structure based on population(and land use), we argue that ICT uses: 1) lead to polarize, rather than to smooth, the urban structural hierarchy, due to the dual role of distance; 2) enable a partial decoupling of activity and activity space node, which challenges our conventional understanding of the role of home and the utility of travel; 3) blur the boundaries of activity districts and hence may play a positive role in enriching districts′ functions, which should not be overlooked in the current urban transformation in China.WANG Bo ZHEN Feng WEI Zongcai GUO Shu CHEN Tingting 2015Chinese Geographical Science2015,25,6:17
14Antigenic variation of the human influenza A(H3N2) virus during the 2014–2015 winter season显示文摘The human influenza A(H3N2) virus dominated the 2014–2015 winter season in many countries and caused massive morbidity and mortality because of its antigenic variation. So far, very little is known about the antigenic patterns of the recent H3N2 virus. By systematically mapping the antigenic relationships of H3N2 strains isolat ed since 2010, we discov ered that two groups with obvious antigenic divergence, named SW13(A/Switzerland/9715293/2013-like strains) and HK14(A/Hong Kong/5738/2014-like strains), co-circulated during the 2014–2015 winter season. HK14 group co-circulated with SW13 in Europe and the United States during this season, while there were few strains of HK14 in China's Mainland, where SW13 has dominated since 2012. Furthermore, we found that substitutions near the receptor-binding site on hemagglutinin played an important role in the antigenic variation of both the groups. These findings provide a comprehensive understanding of the recent antigenic evolution of H3N2 virus and will aid in the selection of vaccine strains.HUA Sha LI XiYan LIU Mi CHENG YanHui PENG YouSong HUANG WeiJuan TAN MinJu WEI HeJiang GUO JunFeng WANG DaYan WU AiPing SHU YueLong JIANG TaiJiao 2015Science China(Life Sciences)2015,58,9:17

19Changes in count and function of splenic lymphocytes from patients with portal hypertension显示文摘AIM: To investigate changes in numbers and proliferative function of splenic lymphocytes in patients with hypersplenism due to portal hypertension (PH), to provide evidence for further study of immune status of the spleen during PH. METHODS: Twelve spleens from patients with hypersplenism due to PH served as the PH group, and four spleens from cases of traumatic spleen rupture were regarded as the control group. After weighing the spleen, lymphocytes were separated and counted using a cell counting plate to calculate the lymphocyte count per gram of spleen tissue (relative quantity) and total lymphocyte count in whole spleen (absolute quantity). The immunohistochemical SP method was used to observe the density and distribution of lymphocytes in the spleen. The MTT method was used to observe changes in lymphocyte proliferative function. RESULTS: As compared to the control group, the splenic lymphocytes in the PH group showed that: (1) There was no difference in distribution but a significant decreasein density; (2) the number of lymphocytes per gram of spleen (relative quantity) decreased significantly (0.822 ± 0.157) × 108 vs (1.174 ± 0.254) × 108, P < 0.01]; (3) with the significant increase in the weight of the PH spleen (832.6 ± 278.2 g vs 211.7 ± 85.6 g, P < 0.01), the total quantity of lymphocytes (absolute quantity) increased significantly (0.685 ± 0.072) × 1011 vs (0.366 ± 0.057) × 1011, P < 0.01]; and (4) the proliferative function of lymphocytes was enhanced: T lymphocytes, (0.022 ± 0.005 vs 0.015 ± 0.003, P < 0.05), and B lymphocytes (0.034 ± 0.006 vs 0.023 ± 0.001, P < 0.01). CONCLUSION: Although lymphocyte density in the spleen decreased in patients with PH, the total quantity of lymphocytes increased because spleen weight increased greatly, along with the proliferating function. With respect to changes in lymphocytes, PH spleens may still have immune function, although it may be disordered. However, complete evaluation of the immune function of the spleen in PH requires more research.Zong-Fang Li Shu Zhang Gao-Bo Lv Ying Huang Wei Zhang Song Ren Jun Yang Shuang-Suo Dang 2008World Journal of Gastroenterology2008,14,15:13
20Genotype × environmental interaction by AMMI and GGE biplot analysis for the provenances of Michelia chapensis in South China显示文摘A provenance trial of Michelia chapensis Dandy in the south of China was carried out in three sites to assess yield and stability analyses. The trials were conducted as randomized, complete block designs with four replications at each site. Additive main effects and multiplicative interaction(AMMI) and genotype main effect and genotype 9 environment interaction(GGE) were employed in the evaluation of provenances; AMMI analyses showed that significant genotype 9 environment interaction effects(P \ 0.05) existed between provenances, capturing 15.11 % of the total sum of squares. The AMMI stability value revealed that provenance 2 was stable, but had low yield. GGE-biplot models showed that provenances 7, 8, 10, and 11 were more stable and highyielding. The GGE results also confirmed that among the three sites, site Jiu Qu Shui was the most ideal environment for representation and discrimination.Runhui Wang Dehuo Hu Huiquan Zheng Shu Yan Ruping Wei 2016Journal of Forestry Research2016,27,3:13
