| 1 | Genetic Analysis and Fine Mapping of Two Genes for Grain Shape and Weight in Rice显示文摘To identify genetic loci controlling grain weight,an elite indica rice variety,Baodali,with large grains was identified and used in this study.Its derived F2,F3 and BC2F2 with another japonica rice variety Zhonghua 11 were used as mapping populations.Linkage analyses demonstrated that two genes controlling grain weight,designated as GW3 and GW6,were mapped to chromosome 3 and chromosome 6,respectively.Fine mapping delimited GW3 to a 122 kb physical distance between two sequence tagged site markers(WGW16 and WGW19) containing 16 open reading frames annotated by The Institute for Genomic Research(http://www.tigr.org).GW6 was further mapped between two simple sequence repeat markers(RM7179 and RM3187).These results are useful for both marker assisted selection of grain weight,and for further cloning of GW genes,which will contribute to the dissection of the molecular mechanism underlying grain weight in rice. | Longbiao Guo Lilian Ma Hua Jiang Dali Zeng Jiang Hu Liwen Wu Zhenyu Gao Guangheng Zhang Qian Qian | 2009 | Journal of Integrative Plant Biology2009，51，1： | 13 |
| 2 | Quantitative Trait Loci for Panicle Layer Uniformity Identified in Doubled Haploid Lines of Rice in Two Environments显示文摘Uniformity of stem height in rice directly affects crop yield potential and appearance,and has become a vital index for rice improvement.In the present study,a doubled haploid(DH) population,derived from a cross between japonica rice Chunjiang 06 and indica rice TN1 was used to analyze the quantitative trait locus(QTL) for three related traits of paniclelayer-uniformity;that is,the tallest panicle height,the lowest panicle height and panicle layer disuniformity in two locations:Hangzhou(HZ) and Hainan(HN).A total of 16 QTLs for three traits distributed on eight chromosomes were detected in two different environments.Two QTLs,qTPH-4 and qTPH-8 were co-located with the QTLs for qLPH-4 and qLPH-8,which were only significant in the HZ environment,whereas the qTPH-6 and qLPH-6 located at the same interval were only significant in the HN environment.Two QTLs,qPLD-10-1 and qPLD-10-2,were closely linked to qTPH-10,and they might have been at the same locus.One QTL,qPLD-3,was detected in both environments,explaining more than 23% of the phenotypic variations.The CJ06 allele of qPLD-3 could increase the panicle layer disuniformity by 9.23 and 4.74 cm in the HZ and HN environments.Except for qPLD-3,almost all other QTLs for the same trait were detected only in one environment,indicating that these three traits were dramatically affected by environmental factors.The results may be useful for elucidation of the molecular mechanism of panicle-layer-uniformity and marker assisted breeding for super-rice. | Liangyong Ma Jinsong Bao Longbiao Guo Dali Zeng Ximing Li Zhijuan Ji Yingwu Xia Changdeng Yang Qian Qian | 2009 | Journal of Integrative Plant Biology2009，51，9： | 7 |
| 3 | A super pan-genomic landscape of rice显示文摘Pan-genomes from large natural populations can capture genetic diversity and reveal genomic complexity.Using de novo longread assembly,we generated a graph-based super pan-genome of rice consisting of a 251-accession panel comprising both cultivated and wild species of Asian and African rice.Our pan-genome reveals extensive structural variations(SVs)and gene presence/absence variations.Additionally,our pan-genome enables the accurate identification of nucleotide-binding leucine-rich repeat genes and characterization of their inter-and intraspecific diversity.Moreover,we uncovered grain weight-associated SVs which specify traits by affecting the expression of their nearby genes.We characterized genetic variants associated with submergence tolerance,seed shattering and plant architecture and found independent selection for a common set of genes that drove adaptation and domestication in Asian and African rice.This super pan-genome facilitates pinpointing of lineage-specific haplotypes for trait-associated genes and provides insights into the evolutionary events that have shaped the genomic architecture of various rice species. | Lianguang Shang Xiaoxia Li Huiying He Qiaoling Yuan Yanni Song Zhaoran Wei Hai Lin Min Hu Fengli Zhao Chao Zhang Yuhua Li Hongsheng Gao Tianyi Wang Xiangpei Liu Hong Zhang Ya Zhang Shuaimin Cao Xiaoman Yu Bintao Zhang Yong Zhang Yiqing Tan Mao Qin Cheng Ai Yingxue Yang Bin Zhang Zhiqiang Hu Hongru Wang Yang Lv Yuexing Wang Jie Ma Quan Wang Hongwei Lu Zhe Wu Shanlin Liu Zongyi Sun Hongliang Zhang Longbiao Guo Zichao Li Yongfeng Zhou Jiayang Li Zuofeng Zhu Guosheng Xiong Jue Ruan Qian Qian | 2022 | Cell Research2022，32，10： | 3 |
| 4 | Association of microRNA polymorphisms with the risk of head and neck squamous cell carcinoma in a Chinese population:a case-control study显示文摘Background:MicroRNA(miRNA) polymorphisms may alter miRNA-related processes,and they likely contribute to cancer susceptibility.Various studies have investigated the associations between genetic variants in several key miRNAs and the risk of human cancers;however,few studies have focused on head and neck squamous cell carcinoma(HNSCC) risk.This study aimed to evaluate the associations between several key miRNA polymorphisms and HNSCC risk in a Chinese population.Methods:In this study,we genotyped five common single-nucleotide polymorphisms(SNPs) in several key miRNAs(miR-149 rs2292832,miR-146 a rs2910164,miR-605 rs2043556,miR-608 rs4919510,and miR-196a2 rs11614913) and evaluated the associations between these SNPs and HNSCC risk according to cancer site with a case-control study including 576 cases and 1552 controls,which were matched by age and sex in a Chinese population.Results:The results revealed that miR-605 rs2043556[dominant model:adjusted odds ratio(OR) 0.71,95%confidence interval(CI) 0.58-0.88;additive model:adjusted OR 0.74,95%CI 0.62-0.89]and miR-196a2 rs11614913(dominant model:adjusted OR 1.36,95%C11.08-1.72;additive model:adjusted OR 1.28,95%C11.10-1.48) were significantly associated with the risk of oral squamous cell carcinoma(OSCC).Furthermore,when these two loci were evaluated together based on the number of putative risk alleles(rs2043556 A and rs11614913 G),a significant locus-dosage effect was noted on the risk of OSCC(P_(trend) < 0.001).However,no significant association was detected between the other three SNPs(miR-149 rs2292832,miR- 146 a rs2910164,and miR-608 rs4919510) and HNSCC risk.Conclusion:Our study provided the evidence that miR-605 rs2043556 and miR-196a2 rs11614913 may have an impact on genetic susceptibility to OSCC in Chinese population. | Limin Miao Lihua Wang Longbiao Zhu Jiangbo Du Xun Zhu Yuming Niu Ruixia Wang Zhibin Hu Ning Chen Hongbing Shen Hongxia Ma | 2016 | Chinese Journal of Cancer2016，35，11： | 2 |

| 8 | Interface synergistic effects induced multi-mode luminescence显示文摘Mechanoluminescence(ML)has become the most promising material for broad applications in display and sensing devices,in which ZnS is the most commonly studied one due to its stable and highly repetitive ML performances.In this work,we have successfully prepared the biphase ZnS on a large scale through the facile in-air molten salt protection strategy.The obtained biphase has the best ML properties,which is mainly attributed to the synergistic effects of piezo-photonic,defect,and interface dislocations.DFT calculations have confirmed that the defects activate the local S and Zn sites and reduce the energy barrier for electron transfer.The much stronger X-ray induced luminescence than the commercial scintillator is also reached.The application of ZnS particles in both papers and inks delivers superior performance.Meanwhile,ZnS particles based screen printing ink is able to directly print on paper,plastic and other carriers to form clear marks.These proposed paper and ink hold great potentials in applications of information security and anti-counterfeiting based on the multi-mode luminescence properties.This work provides a new avenue to understand and realize the high-performance multi-mode luminescence,inspiring more future works to extend on other ML materials and boosting their practical applications. | Ronghua Ma Chunfeng Wang Wei Yan Mingzi Sun Jianxiong Zhao Yuantian Zheng Xu Li Longbiao Huang Bing Chen Feng Wang Bolong Huang Dengfeng Peng | 2022 | Nano Research2022，15，5： | 1 |
| 9 | A Non-Convex Optimization Approach to Dynamic Coverage Problem of Multi-agent Systems in an Environment with Obstacles显示文摘In this paper,a cooperative region reconnaissance problem is investigated where a group of agents are required to fly across and detect events occur in an environment with static obstacles until an effective coverage is achieved.First,the region reconnaissance is formulated as a non-convex optimization problem.A coverage performance index with additional collision and obstacle avoidance constraints is given.Since the optimization index is an implicit function of state variables and cannot be used to compute gradients on state variables directly,an approximate optimization index is selected.Then,a non-convex optimization-based coverage algorithm is proposed to find the optimal reconnaissance location for each agent and guarantee no collisions trajectories among agents and obstacles.Finally,simulation experiments are performed to verify the effectiveness of the proposed approach. | MA Longbiao HE Fenghua WANG Long LI Changxi YAO Yu | 2020 | Journal of Systems Science & Complexity2020，33，2： | 0 |
| 10 | A centromere map based on super pan-genome highlights the structure and function of rice centromeres显示文摘Rice(Oryza sativa)is a significant crop worldwide with a genome shaped by various evolutionary factors.Rice centromeres are crucial for chromosome segregation,and contain some unreported genes.Due to the diverse and complex centromere region,a comprehensive understanding of rice centromere structure and function at the population level is needed.We constructed a high-quality centromere map based on the rice super pangenome consisting of a 251-accession panel comprising both cultivated and wild species of Asian and African rice.We showed that rice centromeres have diverse satellite repeat CentO,which vary across chromosomes and subpopulations,reflecting their distinct evolutionary patterns.We also revealed that long terminal repeats(LTRs),especially young Gypsy-type LTRs,are abundant in the peripheral CentO-enriched regions and drive rice centromere expansion and evolution.Furthermore,high-quality genome assembly and complete telomere-to-telomere(T2T)reference genome enable us to obtain more centromeric genome information despite mapping and cloning of centromere genes being challenging.We investigated the association between structural variations and gene expression in the rice centromere.A centromere gene,OsMAB,which positively regulates rice tiller number,was further confirmed by expression quantitative trait loci,haplotype analysis and clustered regularly interspaced palindromic repeats(CRISPR)/CRISPR-associated protein9 methods.By revealing the new insights into the evolutionary patterns and biological roles of rice centromeres,our finding will facilitate future research on centromere biology and crop improvement. | Yang Lv Congcong Liu Xiaoxia Li Yueying Wang Huiying He Wenchuang He Wu Chen Longbo Yang Xiaofan Dai Xinglan Cao Xiaoman Yu Jiajia Liu Bin Zhang Hua Wei Hong Zhang Hongge Qian Chuanlin Shi Yue Leng Xiangpei Liu Mingliang Guo Xianmeng Wang Zhipeng Zhang Tianyi Wang Bintao Zhang Qiang Xu Yan Cui Qianqian Zhang Qiaoling Yuan Noushin Jahan Jie Ma Xiaoming Zheng Yongfeng Zhou Qian Qian Longbiao Guo Lianguang Shang | 2024 | Journal of Integrative Plant Biology2024，66，2： | 0 |
