| 1 | Multimodality treatment in hepatocellular carcinoma patients with tumor thrombi in portal vein显示文摘AIM To compare the therapeutic effect andsignificances of multimodality treatment forhepatocellular carcinoma (HCC) with tumorthrombi in portal vein (PVTT).METHODS HCC patients (n = 147) with tumortrombi in the main portal vein or the first branchof portal vein were divided into four groups bythe several therapeutic methods. There wereconservative treatment group in 18 out ofpatients (group A); and hepatic artery ligation(HAL) and/or hepatic artery infusion (HAl)group in 18 patients (group B), in whompostoberative chemoembolization was doneperiodically; group of removal of HCC with PVTTin 79 (group C) and group of transcatheterhepatic arterial chemoembolization (TACE) orHAl and/or portal vein infusion (PVI) afteroperation in 32 (group D).RESULTS The median survival period was 12months in our series and the 1-, 3-, and 5-yearsurvival rates were 44.3%, 24.5% and 15.2%,respectively. The median survival times were 2,5, 12 and 16 months in group A, B, C and D,respectively. The 1-, 3- and 5-year survival rateswere 5.6%, 0% and 0% in group A; 22.2%,5.6% and 0% in group B; 53.9%, 26.9% and16.6% in group C; 79.3%, 38.9% and 26.8% ingroup D, respectively. Significant differenceappeared in the survival rates among the groups(P<0.05).CONCLUSION Hepatic resection with removalof tumor thrombi and HCC should increase thecurative effects and be encouraged for theprolongation of life span and quality of life forHCC patients with PVTT, whereas the besttherapeutic method for HCC with PVTT is withregional hepatic chemotherapy orchemoemblization after hepatic resection withremoval of tumor thrombi. | Jia Fan Zhi Quan Wu Zhao You Tang Jian Zhou Shuang Jian Qiu Zeng Chen Ma Xin Da Zhou Sheng Long Ye Liver Cancer Institute, Zhongshan Hospital, Fudan University Medical Center (Former Shanghai University), 136 Yixueyuan Road, Shanghai 200032, China | 2001 | World Journal of Gastroenterology2001，7，1： | 80 |
| 2 | Significance and relationship between Yes-associated protein and survivin expression in gastric carcinoma and precancerous lesions显示文摘AIM:To analyze the differences and relevance of Yes-associated protein (YAP) and survivin, and to explore the correlation and signifi cance of their expression in gastric carcinoma and precancerous lesions.METHODS: The PV9000 immunohistochemical method was used to detect the expression of YAP and survivin in 98 cases of normal gastric mucosa, 58 intestinal metaplasia (IM), 32 dysplasia and 98 gastric carcinoma.RESULTS: The positive rates of YAP in dysplasia (37.5%) and gastric carcinoma (48.0%) were significantly higher than that in normal gastric mucosa (13.3%), P<0.01. The positive rates of survivin in IM (53.4%), dysplasia (59.4%) and gastric carcinoma (65.3%) were significantly higher than in normal gastric mucosa (11.2%), P<0.01. Survivin expression gradually increased from 41.7% in well differentiated adenocarcinoma through 58.3% in moderately differentiated adenocarcinoma to 75.6% in poorly differentiated adenocarcinoma, with significant Rank correlation, rk=0.279, P<0.01. The positive rate of survivin in gastric carcinoma of diffused type (74.6%) was significantly higher than that in intestinal type (51.3%), P<0.05. In gastric carcinoma with lymph node metastasis (76.9%), the positive rate of survivin was signifi cantly higher than that in the group without lymph node metastasis (41.2%), P<0.01. In 98 cases of gastric carcinoma, the expression of YAP and of survivin were positively correlated, rk=0.246, P<0.01.CONCLUSION: YAP may play an important role as a carcinogenic factor and may induce survivin expression. Detecting both markers together may help in early diagnosis of gastric carcinoma. | Chun-Li Da Yan Xin Jing Zhao Xiang-Dong Luo | 2009 | World Journal of Gastroenterology2009，15，32： | 53 |

| 4 | Neutrophil extracellular traps mediate the crosstalk between glioma progression and the tumor microenvironment via the HMGB1/RAGE/IL-8 axis显示文摘Objective:Neutrophil extracellular traps(NETs)produced by tumor-infiltrating neutrophils(TINs)are associated with poor prognosis in patients with several types of cancer.However,the mechanisms underlying the involvement of NETs in glioma progression remain largely unknown.This study aimed to elucidate the roles of NETs in biological processes that drive the crosstalk between glioma progression and the tumor microenvironment.Methods:Neutrophil infiltration and NETs formation were investigated in glioma tissue through immunohistochemistry,and their relationships with clinicopathological features and outcomes were statistically evaluated.The effects of NETs on glioma cell progression were studied in a co-culture system.In vivo and in vitro experiments validated the reactive oxygen species activity and cytokine production of TINs,as well as the ERK signaling pathway activation and the metastasis of gliomas.Results:Neutrophil infiltration and NETs formation were induced in high-grade glioma compared with low-grade glioma.NETs induced by TINs were determined to be an oncogenic marker of high-grade gliomas and to be involved in cell proliferation and invasion.NETs overproduction promoted glioma cell proliferation,migration,and invasion.Furthermore,HMGB1 was found to bind to RAGE and activate the NF-κB signaling pathway in vitro.In addition,NETs stimulated the NF-κB signaling pathway,thus promoting IL-8 secretion in glioblastoma.Subsequently,IL-8 recruited neutrophils which in turn mediated NETs formation via the PI3 K/AKT/ROS axis in TINs.Conclusions:Our results suggest that NETs produced by TINs mediate the crosstalk between glioma progression and the tumor microenvironment by regulating the HMGB1/RAGE/IL-8 axis.Targeting NETs formation or IL-8 secretion may be an effective approach to inhibit glioma progression. | Caijun Zha Xiangqi Meng Lulu Li Shan Mi Da Qian Ziwei Li Pengfei Wu Shaoshan Hu Shihong Zhao Jinquan Cai Yanhong Liu | 2020 | Cancer Biology & Medicine2020，17，1： | 19 |
| 5 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014，27，5： | 17 |

| 7 | Removal of copper ions from aqueous solution by calcium alginate immobilized kaolin显示文摘Kaolin has been widely used as an adsorbent to remove heavy metal ions from aqueous solutions.However,the lower heavy metal adsorption capacity of kaolin limits its practical application.A novel environmental friendly material,calcium alginate immobilized kaolin (kaolin/CA),was prepared using a sol-gel method.The effects of contact time,pH,adsorbent dose,and temperature on Cu 2+ adsorption by kaolin/CA were investigated.The Langmuir isotherm was used to describe the experimental adsorption,the maximum Cu 2+ adsorption capacity of the kaolin/CA reached up to 53.63 mg/g.The thermodynamic studies showed that the adsorption reaction was a spontaneous and endothermic process. | Yanhui Li Bing Xia Quansheng Zhao Fuqiang Liu Pan Zhang Qiuju Du DechangWang Da Li ZonghuaWang Yanzhi Xia | 2011 | Journal of Environmental Sciences2011，23，3： | 14 |
| 8 | Degradation Mechanism of Cationic Red X-GRL by Ozonation显示文摘The degradation mechanism of Cationic Red X-GRL was investigated when the intermediates, the nitrate ion and the pH were analyzed in the ozonation. The degradation of the Cationic Red X-GRL includes the de-auxochrome stage, the decolour stage, and the decomposition of fragment stage. During the degradation process, among the six nitrogen atoms of Cationic Red X-GRL, one is transferred into a nitrate ion, one becomes the form of an amine compound, and the rest four are transformed into two molecules of nitrogen. In the course of the ozonation of Cationic Red X-GRL, the direct attack of ozone is the main decolour effect. | Wei Rong ZHAO*, Xin Hua XU, Hui Xiang SHI, Da Hui WANG Department of Environmental Engineering, Zhejiang University, Hangzhou 310027 | 2003 | Chinese Chemical Letters2003，14，12： | 14 |
| 9 | Clinical significance of telomerase activity in peritoneal lavage fluid from patients with gastric cancer and its relationship with cellular proliferation显示文摘AIM: To evaluate the efficacy of telomerase activity assay and peritoneal lavage cytology (PLC) examination in peritoneal lavage fluid for the prediction of peritoneal metastasis in gastric cancer patients, and to explore the relationship between telomerase activity and proliferating cell nuclear antigen expression. METHODS: Telomeric repeated amplification protocol (TRAP)-enzyme-linked immunosorbent assay (ELISA) was performed to measure the telomerase activity in 60 patients with gastric cancer and 50 with peptic ulcer. PLC analysis of the 60 patients with gastric cancer was used for comparison. The proliferating cell nuclear antigen (PCNA) in gastric carcinoma was immunohistochemically examined. RESULTS: The telomerase activity and PLC positive rate in peritoneal lavage fluid from patients with gastric cancer was 41.7/ (25/60), and 25.0/ (15/60), respectively. The positive rate of telomerase activity was significantly higher than that of PLC in the group of pT4 (15/16 vs 9/16, P < 0.05), P1-3 (13/13 vs 9/13, P < 0.05) and diffuse type (22/42 vs 13/42, P < 0.05). The patients with positive telomerase activity, peritoneal metastasis, and serosal invasion had signifi cantly higher levels of average PCNA proliferation index (PI), (55.00 ± 6.59 vs 27.43 ± 7.72, 57.26 ± 10.18 vs 29.15 ± 8.31, and 49.82 ± 6.74 vs 24.65 ± 7.33, respectively, P < 0.05).CONCLUSION: The TRAP assay for telomerase activity is a useful adjunct for cytologic method in the diagnosis of peritoneal micrometastasis and well related to higher proliferating activity of gastric cancer. The results of this study also suggest a promising future therapeutic strategy for treating peritoneal dissemination based on telomerase inhibition. | Ming-Xu Da Xiao-Ting Wu Tian-Kang Guo Zi-Guang Zhao Ting Luo Kun Qian Ming-Ming Zhang Jie Wang | 2007 | World Journal of Gastroenterology2007，13，22： | 11 |
| 10 | Geochemical features and genesis of the natural gas and bitumen in paleo-oil reservoirs of Nanpanjiang Basin, China显示文摘Bitumen from the Nanpanjiang Basin occurs mainly in the Middle Devonian and Upper Permian reef limestone paleo-oil reservoirs and reserves primarily in holes and fractures and secondarily in minor matrix pores and bio-cavities. N2 is the main component of the natural gas and is often associated with pyrobitumen in paleo-oil reservoirs. The present study shows that the bitumen in paleo-oil reservoirs was sourced from the Middle Devonian argillaceous source rock and belongs to pyrobitumen by crude oil cracking under high temperature and pressure. But the natural gas with high content of N2 is neither an oil-cracked gas nor a coal-formed gas generated from the Upper Permian Longtan Formation source rock, instead it is a kerogen-cracked gas generated at the late stage from the Middle Devonian argilla- ceous source rock. The crude oil in paleo-oil reservoirs completely cracked into pyrobitumen and methane gas by the agency of hugely thick Triassic deposits. After that, the abnormal high pressure of methane gas reservoirs was completely destroyed due to the erosion of 2000--4500-m-thick Triassic strata. But the kerogen-cracked gas with normal pressure was preserved under the relatively sealed condition and became the main body of the gas shows. | ZHAO MengJun ZHANG ShuiChang ZHAO Lin DA Jiang | 2007 | Science China Earth Sciences2007，50，5： | 11 |
| 11 | A study of hydrate plug formation in a subsea natural gas pipeline using a novel high-pressure flow loop显示文摘The natural gas pipeline from Platform QK18-1 in the southwest of Bohai Bay to the onshore processing facility is a subsea wet gas pipeline exposed to high pressure and low temperature for a long distance. Blockages in the pipeline occur occasionally. To maintain the natural gas flow in the pipeline, we proposed a method for analyzing blockages and ascribed them to the hydrate formation and agglomeration. A new high-pressure flow loop was developed to investigate hydrate plug formation and hydrate particle size, using a mixture of diesel oil, water, and natural gas as experimental fluids. The influences of pressure and initial flow rate were also studied. Experimental results indicated that when the flow rate was below 850 kg/h, gas hydrates would form and then plug the pipeline, even at a low water content (10%) of a water/oil emulsion. Furthermore, some practical suggestions were made for daily management of the subsea pipeline. | Li Wenqing Gong Jing Lü Xiaofang Zhao Jiankui Feng Yaorong Yu Da | 2013 | Petroleum Science2013，10，1： | 11 |

| 14 | mi R-192-5p regulates lipid synthesis in non-alcoholic fatty liver disease through SCD-1显示文摘AIM To evaluate the levels of mi R-192-5 p in non-alcoholic fatty liver disease(NAFLD) models and demonstrate the role of mi R-192-5 p in lipid accumulation. METHODS Thirty Sprague Dawley rats were randomly divided into three groups, which were given a standard diet, a high-fat diet(HFD), and an HFD with injection of liraglutide. At the end of 16 weeks, hepatic mi R-192-5 p and stearoyl-Co A desaturase 1(SCD-1) levels were measured. Mi R-192-5 p mimic and inhibitor and SCD-1 si RNA were transfected into Huh7 cells exposed to palmitic acid(PA). Lipid accumulation was evaluated by oil red O staining and triglyceride assays. Direct interaction was validated by dual-luciferase reporter gene assays.RESULTS The HFD rats showed a 0.46-fold decrease and a 3.5-fold increase in hepatic mi R-192-5 p and SCD-1 protein levels compared with controls, respectively, which could be reversed after disease remission by liraglutide injection(P < 0.01). The Huh7 cells exposed to PA also showed down-regulation and up-regulation of mi R-192-5 p and SCD-1 protein levels, respectively(P < 0.01). Transfection with mi R-192-5 p mimic and inhibitor in Huh7 cells induced dramatic repression and promotion of SCD-1 protein levels, respectively(P < 0.01). Luciferase activity was suppressed and enhanced by mi R-192-5 p mimic and inhibitor, respectively, in wild-type SCD-1(P < 0.01) but not in mutant SCD-1. Mi R-192-5 p overexpression reduced lipid accumulation significantly in PA-treated Huh7 cells, and SCD-1 si RNA transfection abrogated the lipid deposition aggravated by mi R-192-5 p inhibitor(P < 0.01).CONCLUSION This study demonstrates that mi R-192-5 p has a negative regulatory role in lipid synthesis, which is mediated through its direct regulation of SCD-1. | Xiao-Lin Liu Hai-Xia Cao Bao-Can Wang Feng-Zhi Xin Rui-Nan Zhang Da Zhou Rui-Xu Yang Ze-Hua Zhao Qin Pan Jian-Gao Fan | 2017 | World Journal of Gastroenterology2017，23，46： | 10 |
| 15 | Chronic niacin overload may be involved in the increased prevalence of obesity in US children显示文摘AIM: To investigate nicotinamide’s action on glucose metabolism, and the association between niacin consumption and obesity prevalence. METHODS: Dynamic nicotinamide’s effect on plasma hydrogen peroxide and glucose metabolism was in- vestigated using oral glucose tolerance tests with or without nicotinamide in the same five healthy subjects.Lag-regression analysis was used to examine the association between the niacin consumption and the obesity prevalence among US children using the data from the Economic Research Service of the US Department of Agriculture and from US Centers for Disease Control and Prevention, respectively. RESULTS: Compared with the control oral glucose tolerance test, the 1-h plasma hydrogen peroxide (1.4 ± 0.1 μmol/L vs 1.6 ± 0.1 μmol/L, P = 0.016) and insulin levels (247.1 ± 129.0 pmol/L vs 452.6 ± 181.8 pmol/L, P = 0.028) were signif icantly higher, and the 3-h blood glucose was signif icantly lower (5.8 ± 1.2 mmol/L vs 4.5 ± 1.1 mmol/L, P = 0.002) after coadministration of glucose and 300 mg nicotinamide. The obesity prevalence among American children increased with the increasing per capita niacin consumption, the increasing grain contribution to niacin due to niacin-fortification, and the increasing niacin-fortified ready-to-eat cereal consumption, with a 10-year lag. The regression analyses showed that the obesity prevalence in the US children of all age groups was determined by niacin consumption (R2 = 0.814, 0.961 and 0.94 for 2-5 years, 6-11 years and 12-19 years age groups, respectively). CONCLUSION: The appetite-stimulating effect of nicotinamide appears to involve oxidative stress. Excess niacin consumption may be a major factor in the increased obesity prevalence in US children. | Li, Da Sun, Wu-Ping Zhou, Yi-Ming Liu, Qi-Gui Zhou, Shi-Sheng Luo, Ning Bian, Fu-Ning Zhao, Zhi-Gang Guo, Ming | 2010 | World Journal of Gastroenterology2010，16，19： | 10 |
| 16 | Clinicopathological significance of B-cell-specific Moloney murine leukemia virus insertion site 1 expression in gastric carcinoma and its precancerous lesion显示文摘AIM: To explore the relation between B-cell-specific Moloney murine leukemia virus insertion site 1 (Bmi-1) expression and the clinicopathological features of gastric carcinoma (GC). METHODS: Immunohistochemistry was used to detect the expression of Bmi-1 and ki-67. Double-labeling staining was used to display the distribution of Bcl-2+/ki-67- cells in 162 cases of GC and its matched normal mucosa and precancerous lesion. RESULTS: The positive rate of Bmi-1 expression in GC (52.5%) was significantly higher than that in normal gastric mucosa (21.6%, χ2 = 33.088, P < 0.05). The Bmi-1 expression in GC was closely related with the Lauren's and Borrmann's classification and clinical stage (χ2 = 4.400, 6.122 and 11.190, respectively, P < 0.05). The expression of ki-67 was related to the Borrmann's classification (χ2 = 13.380, P < 0.05). Bcl-2 expression was correlated with the Lauren's classification (χ2 = 4.725, P < 0.05), and the Bmi-1expression both in GC (rk = 0.157, P < 0.05) and in intestinal metaplasia (rk = 0.270, P < 0.05). CONCLUSION: Abnormal Bmi-1 expression in GC may be involved in cell proliferation, apoptosis and cancerization. This marker can objectively indicate the clinicopathological characteristics of GC. | Jing Zhao Xiang-Dong Luo Chun-Li Da Yan Xin | 2009 | World Journal of Gastroenterology2009，15，17： | 9 |
| 17 | Nicotinamide overload may play a role in the development of type 2 diabetes显示文摘AIM: To investigate whether nicotinamide overload plays a role in type 2 diabetes. METHODS: Nicotinamide metabolic patterns of 14diabetic and 14 non-diabetic subjects were compared using HPLC. Cumulative effects of nicotinamide and N1-methylnicotinamide on glucose metabolism, plasma H2O2 levels and tissue nicotinamide adenine dinucleotide (NAD) contents of adult Sprague-Dawley rats were observed. The role of human sweat glands and rat skin in nicotinamide metabolism was investigated using sauna and burn injury, respectively. RESULTS: Diabetic subjects had significantly higher plasma N 1-methylnicotinamide levels 5 h after a 100-mg nicotinamide load than the non-diabetic subjects (0.89 ± 0.13 μmol/L vs 0.6 ± 0.13 μmol/L, P < 0.001). Cumulative doses of nicotinamide (2 g/kg) significantly increased rat plasma N 1-methy lnico-tinamide concentrations associated with severe insulin resistance, which was mimicked by N1-methy-lnicotinamide. Moreover, cumulative exposure to N1-methylnicotinamide (2 g/kg) markedly reduced rat muscle and liver NAD contents and erythrocyte NAD/NADH ratio, and increased plasma H2O2 levels. Decrease in NAD/NADH ratio and increase in H2O2 generation were also observed in human erythrocytes after exposure to N1-methylnicotinamide in vitro. Sweating eliminated excessive nicotinamide (5.3-fold increase in sweat nicotinamide concentration 1 h after a 100-mg nicotinamide load). Skin damage or aldehyde oxidase inhibition with tamoxifen or olanzapine, both being notorious for impairing glucose tolerance, delayed N1-methylnicotinamide clearance. CONCLUSION: These f indings suggest that nicotinamide overload, which induced an increase in plasma N 1-methylnicotinamide, associated with oxidative stress and insulin resistance, plays a role in type 2 diabetes. | Shi-Sheng Zhou Da Li Wu-Ping Sun Ming Guo Yong-Zhi Lun Yi-Ming Zhou Fu-Cheng Xiao Li-Xin Jing Shen-Xia Sun Li-Bin Zhang Ning Luo Fu-Ning Bian Wei Zou Lai-Bin Dong Zhi-Gang Zhao Sheng-Fan Li Xiao-Jie Gong Zeng-Guo Yu Chang-Bin Sun Cong-Long Zheng Dong-Ju Jiang Zheng-Ning Li | 2009 | World Journal of Gastroenterology2009，15，45： | 8 |
| 18 | Interaction between cyclooxygenase-2,Snail,and E-cadherin in gastric cancer cells显示文摘AIM:To investigate the mechanisms of how cyclooxygenase-2(COX-2)regulates E-cadherin in gastric cancer cells.METHODS:COX-2 expression in human gastric cancer cell lines SGC-7901,BGC-823,MGC-803 and AGS were measured at the mRNA and protein level.COX-2 rich cell line SGC-7901 was chosen for subsequent experiments.siRNA mediated gene knockdown was used to investigate the impact of COX-2 on nuclear factor-κB (NF-κB),Snail,and E-cadherin in gastric cancer cells.Gene expression was determined by Western blot and real-time polymerase chain reaction.To analyze whether NF-κB inhibition could interrupt the modulatory effect of COX-2 or prostaglandin E2(PGE2)on E-cadherin,gastric cancer cells were treated with celecoxib or PGE2,in the presence of NF-κB specific siRNA.RESULTS:Highest expression level of COX-2 was found in SGC-7901 cells,both at mRNA and protein levels.siRNA mediated down-regulation of COX-2 led to a reduced expression of NF-κB and Snail,but an increased expression of E-cadherin in SGC-7901 cells.siRNA mediated down-regulation of NF-κB also led to a reduced expression of E-cadherin and Snail in SGC-7901 cells.However,COX-2 expression did not alter after cells were treated with NF-κB specific siRNA in SGC-7901 cells.Treatment of SGC-7901 cells with celecoxib led to a reduced expression of Snail but an increased expression of E-cadherin.In contrast,treatment of SGC-7901 cells with PGE2 led to an increased Snail and a decreased E-cadherin.However,siRNAmediated knockdown of NF-κB partially abolished the effect of celecoxib and PGE2 on the regulation of E-cadherin and Snail in SGC-7901 cells.CONCLUSION:COX-2 likely functions upstream of NF-κB and regulates the expression of E-cadherin via NF-κB/Snail signaling pathway in gastric cancer cells. | Xiao-Jun Liu Zhao-Feng Chen Hai-Long Li Ze-Nan Hu Min Liu Ai-Ping Tian Da Zhao Jing Wu Yong-Ning Zhou Liang Qiao | 2013 | World Journal of Gastroenterology2013，19，37： | 8 |

| 20 | The origin of Wx^(la) provides new insights into the improvement of grain quality in rice显示文摘Appearance and taste are important factors in rice(Oryza sativa) grain quality. Here, we investigated the taste scores and related eating-quality traits of533 diverse cultivars to assess the relationships between—and genetic basis of—rice taste and eating-quality. A genome-wide association study highlighted the Wx gene as the major factor underlying variation in taste and eating quality. Notably, a novel waxy(Wx) allele, Wx^(la), which combined two mutations from Wx^(b) and Wx^(in), exhibited a unique phenotype. Reduced GBSSI activity conferred Wx^(la) rice with both a transparent appearance and good eating quality. Haplotype analysis revealed that Wx^(la) was derived from intragenic recombination. In fact,the recombination rate at the Wx locus was estimated to be 3.34 kb/c M, which was about 75-fold higher than the genome-wide mean, indicating that intragenic recombination is a major force driving diversity at the Wx locus. Based on our results, we propose a new network for Wx evolution, noting that new Wx alleles could easily be generated by crossing genotypes with different Wx alleles. This study thus provides insights into the evolution of the Wx locus and facilitates molecular breeding for quality in rice. | Hao Zhou Duo Xia Da Zhao Yanhua Li Pingbo Li Bian Wu Guanjun Gao Qinglu Zhang Gongwei Wang Jinghua Xiao Xianghua Li Sibin Yu Xingming Lian Yuqing He | 2021 | Journal of Integrative Plant Biology2021，63，5： | 8 |
