| 1 | A Rare Allele of GS2 Enhances Grain Size anc Grain Yield in Rice显示文摘谷物尺寸决定谷物重量并且影响谷物质量。调整谷物尺寸的几主要量的特点 loci (QTL ) 被克隆;然而,我们调整米饭谷物的尺寸的内在的机制的理解仍然保持碎片。这里,我们报导克隆和主导的 QTL 的描述,染色体 2 上的谷物尺寸(GS2 ) 编码调整生长的因素 4,一个 transcriptional 管理者。GS2 本地化到原子核并且可以充当抄写使活跃之物。影响 microRNA 的有约束力的地点的 GS2 的一个稀罕变化, OsmiR396c,原因提高了 GS2/OsGRF4 的表示。GS2 表示的增加导致更大的房间和房间的增加的数字,它因此提高谷物重量和产量。进米饭栽培变种的 GS2/OsGRF4 的这稀罕等位基因的介绍能显著地提高谷物重量和增加谷物产量,用在引起产量很高的米饭变化的可能的应用。 | Jiang Hu Yuexing Wang Yunxia Fang Longjun Zeng Jie Xu Haiping Yu Zhenyuan Shi Jiangjie Pan Dong Zhang Shujing Kang Li Zhu Guojun Dong Longbiao Guo Dali Zeng Guangheng Zhang Lihong Xie Guosheng Xiong Jiayang Li Qian Qian | 2015 | Molecular Plant2015，8，10： | 57 |
| 2 | A Strigolactone Biosynthesis Gene Contributed to the Green Revolution in Rice显示文摘Plant architecture is a complex agronomic trait and a major factor of crop yield,which is affected by several important hormones.Strigolactones(SLs)are identified as a new class hormoneinhibiting branching in many plant species and have been shown to be involved in various developmental processes.Genetical and chemical modulation of the SL pathway is recognized as a promising approach to modify plant architecture.However,whether and how the genes involved in the SL pathway could be utilized in breeding still remain elusive.Here,we demonstrate that a partial loss-of-function allele of the SL biosynthesis gene,HIGH TILLERING AND DWARF 1/DWARF17(HTD1/D17),which encodes CAROTENOID CLEAVAGE DIOXYGENASE 7(CCD7),increases tiller number and improves grain yield in rice.We found that the HTD1 gene had been widely utilized and co-selected with Semidwarf 1(SD1),both contributing to the improvement of plant architecture in modern rice varieties since the Green Revolution in the 1960s.Understanding how phytohormone pathway genes regulate plant architecture and how they have been utilized and selected in breeding will lay the foundation for developing the rational approaches toward improving crop yield. | Yuexing Wang Lianguang Shang Hong Yu Longjun Zeng Jiang Hu Shen Ni Yuchun Rao Sanfeng Li Jinfang Chu Xiangbing Meng Lei Wang Ping Hu Jijun Yan Shujing Kang Minghao Qu Hai Lin Tao Wang Quan Wang Xingming Hu Hongqi Chen Bing Wang Zhenyu Gao Longbiao Guo Dali Zeng Xudong Zhu Guosheng Xiong Jiayang Li Qian Qian | 2020 | Molecular Plant2020，13，6： | 23 |
| 3 | 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://gffzzb05470f0357b4fe5h5nnkb5nq5okx66nb.ffgz.tsg.suse.edu.cn).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 |
| 4 | ALK,the Key Gene for Gelatinization Temperature,is a Modifier Gene for Gel Consistency in Rice显示文摘Gelatinization temperature(GT) is an important parameter in evaluating the cooking and eating quality of rice.Indeed,the phenotype,biochemistry and inheritance of GT have been widely studied in recent times.Previous map-based cloning revealed that GT was controlled by ALK gene,which encodes a putative soluble starch synthase II-3.Complementation vector and RNAi vector were constructed and transformed into Nipponbare mediated by Agrobacterium.Phenotypic and molecular analyses of transgenic lines provided direct evidence for ALK as a key gene for GT.Meanwhile,amylose content,gel consistency and pasting properties were also affected in transgenic lines.Two of four nonsynonymous single nucleotide polymorphisms in coding sequence of ALK were identified as essential for GT.Based on the single nucleotide polymorphisms(SNPs),two new sets of SNP markers combined with one cleaved amplified polymorphic sequence marker were developed for application in rice quality breeding. | Zhenyu Gao Dali Zeng Fangmin Cheng Zhixi Tian Longbiao Guo Yan Su Meixian Yan Hua Jiang Guojun Dong Yuchen Huang Bin Han Jiayang Li Qian Qian | 2011 | Journal of Integrative Plant Biology2011，53，9： | 13 |
| 5 | Responses of root growth of Alhagi sparsifolia Shap. (Fabaceae) to different simulated groundwater depths in the southern fringe of the Taklimakan Desert, China显示文摘Alhagi sparsifolia Shap. (Fabaceae) is a spiny, perennial herb. The species grows in the salinized, arid regions in North China. This study investigated the response characteristics of the root growth and the distribution of one-year-old A. sparsifolia seedlings to different groundwater depths in controlled plots. The ecological adaptability of the root systems of A. sparsifolia seedlings was examined using the artificial digging method. Results showed that: (1) A. sparsifolia seedlings adapted to an increase in groundwater depth mainly through increasing the penetration depth and growth rate of vertical roots. The vertical roots grew rapidly when soil moisture content reached 3%-9%, but slowly when soil moisture content was 13%-20%. The vertical roots stopped growing when soil moisture content reached 30% (the critical soil moisture point). (2) The morphological plasticity of roots is an important strategy used by A. sparsifolia seedlings to obtain water and adapt to dry soil conditions. When the groundwater table was shallow, horizontal roots quickly expanded and tillering increased in order to compete for light resources, whereas when the groundwater table was deeper, vertical roots developed quickly to exploit space in the deeper soil layers. (3) The decrease in groundwater depth was probably responsible for the root distribution in the shallow soil layers. Root biomass and surface area both decreased with soil depth. One strategy of A. sparsifolia seedlings in dealing with the increase in groundwater depth is to increase root biomass in the deep soil layers. The relationship between the root growth/distribution of A. sparsifolia and the depth of groundwater table can be used as guidance for harvesting A. sparsifolia biomass and managing water resources for forage grasses. It is also of ecological significance as it reveals how desert plants adapt to arid environments. | FanJiang ZENG Cong SONG HaiFeng GUO Bo LIU WeiCheng LUO DongWei GUI Stefan ARNDT DaLi GUO | 2013 | Journal of Arid Land2013，5，2： | 13 |
| 6 | ABNORMAL FLOWER AND GRAIN 1 encodes OsMADS6 and determines palea identity and affects rice grain yield and quality显示文摘The palea and lemma are floral organ structures unique to grasses;these structures form the hull and directly affect grain size and quality. However, the molecular mechanisms controlling the development of the hull are not well understood. In this study, we characterized the rice(Oryza sativa) abnormal flower and grain1(afg1) mutant, a new allele of OsMADS6. Similar to previously characterized osmads6 alleles, in the afg1 floret, the palea lost its marginal region and acquired the lemma identity. However, in contrast to other osmads6 alleles, the afg1 mutant showed altered grain size and grain quality, with decreased total starch and amylose contents, and increased protein and soluble sugar contents. The analysis of transcriptional activity suggested that AFG1 is a transcriptional activator and may affect grain size by regulating the expression levels of several genes related to cell expansion and proliferation in the afg1 mutant. These results revealed that AFG1 plays an important role in determining palea identity and affecting grain yield and quality in rice. | Xiaoqi Yu Saisai Xia Qiankun Xu Yuanjiang Cui Ming Gong Dali Zeng Qiang Zhang Lan Shen Guiai Jiao Zhenyu Gao Jiang Hu Guangheng Zhang Li Zhu Longbiao Guo Deyong Ren Qian Qian | 2020 | Science China(Life Sciences)2020，63，2： | 10 |
| 7 | Xiaowei, a New Rice Germplasm for Large-Scale Indoor Research显示文摘Dear Editor,Rice (Oryza sativa)is a model monocot plant for biological studies due to its relatively small genome,rich germplasm resources,and high-efficiency transformation methods.Although significant progress has been made in rice genomics and functional genomics research (Li et al.,2018),large-scale indoor research toward better understanding of rice biology is hampered by its long growth period and extreme dependence on the natural environment for cultivation.There are some rice germplasms that have a short growth period and short plant height,such as Kitaake. | Shikai Hu Xingming Hu Jiang Hu Lianguang Shang Guojun Dong Dali Zeng Longbiao Guo Qian Qian | 2018 | Molecular Plant2018，11，11： | 10 |
| 8 | Characterization and fine mapping of an early senescence mutant (es-t) in Oryza sativa L.显示文摘An es-t (early senescence-temporary) mutant, produced by ethylene methylsulfonate treatment of strain Nipponbare, was identified in rice. The leaves of es-t appeared yellow at the seedling stage, and had decreased chlorophyll content. Rust spots were found during growth in es-t, especially at the leaf margin and tip. The plants showed a typical early-senescence phenotype at the milky stage. The leaf surface of es-t appeared smoother than wild-type leaves under a scanning electron microscope, because the leaves lack siliceous protuberances around the stoma. Chloroplasts grow abnormally and are filled with many starch grains in es-t. Paraffin section analysis showed that the development of the sclerenchyma cells and vascular bundles were also abnormal in es-t. Genetic analysis indicated that es-t was controlled by a recessive gene, which was finely mapped to a 42-kb interval on chromosome 5. These results will facilitate the positional cloning and functional studies of the gene. | YANG YaoLong RAO YuChun LIU HuiJuan FANG YunXia DONG GuoJun HUANG LiChao LENG YuJia GUO LonBiao ZHANG GuangHeng HU Jiang GAO ZhenYu QIAN Qian ZENG DaLi | 2011 | Chinese Science Bulletin2011，56，23： | 8 |
| 9 | Development of nutritious rice with high zinc/selenium and low cadmium in grains through QTL pyramiding显示文摘Enriching zinc(Zn) and selenium(Se) levels,while reducing cadmium(Cd) concentration in rice grains is of great benefit for human diet and health.Large natural variations in grain Zn, Se, and Cd concentrations in different rice accessions enable Zn/Sebiofortification and Cd-minimization through molecular breeding. Here, we report the development of new elite varieties by pyramiding major quantitative trait loci(QTLs) that significantly contribute to high Zn/Se and low Cd accumulation in grains. A chromosome segment substitution line CSSLGCC7 with the PA64s-derived GCC7 allele in the 93-11 background, exhibited steadily higher Mn and lower Cd concentrations in grains than those of 93-11. This elite chromosome segment substitution line(CSSL) was used as the core breeding material to cross with CSSLs harboring other major QTLs for essential mineral elements, especially CSSLGZC6 for grain Zn concentration and CSSLGSC5 for grain Se concentration. The CSSLGCC7+GZC6 and CSSLGCC7+GSC5 exhibited lower Cd concentration with higher Zn and Se concentrations in grains, respectively. Our study thus provides elite materials for rice breeding targeting high Zn/Se and low Cd concentrations in grains. | Chaolei Liu Shilin Ding Anpeng Zhang Kai Hong Hongzhen Jiang Shenglong Yang Banpu Ruan Bin Zhang Guojun Dong Longbiao Guo Dali Zeng Qian Qian Zhenyu Gao | 2020 | Journal of Integrative Plant Biology2020，62，3： | 7 |
| 10 | 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 |
| 11 | Genetic analysis and fine-mapping of a dwarfing with withered leaf-tip mutant in rice显示文摘A dwarf mutant of rice(Oryza sativa L.) by mutagenesis of ethylene methylsulfonate(EMS) treatment from Nipponbare was identi-fied.The mutant exhibited phenotypes of dwarfism and withered leaf tip(dwl1).Based on the internode length of dwl1,this mutant be-longs to the dm type of dwarfing.Analysis of elongation of the second sheath and α-amylase activity in endosperm showed that the phe-notype caused by dwl1 was insensitive to gibberellin acid treatment.Using a large F2 population derived from a cross between the dwl1 and an indica rice variety,TN1,the DWL1 gene was mapped to the terminal region of the long arm of chromosome 3.Fine-mapping de-limited it into a 46 kb physical distance between two STS markers,HL921 and HL944,where 6 open reading frames were predicted.Cloning of DWL1 will contribute to dissecting molecular mechanism that regulates plant height in rice,which will be beneficial to mo-lecular assisted selection of this important trait. | Liang Jiang Longbiao Guo Hua Jiang Dali Zeng Jiang Hu Liwen Wu Jian Liu Zhenyu Gao Qian Qian | 2008 | Journal of Genetics and Genomics2008，35，12： | 7 |
| 12 | Methane dehydroaromatization with periodic CH_4-H_2 switch:A promising process for aromatics and hydrogen显示文摘Long-term stability test of Mo/HZSM-5-N catalysts(HZSM-5-N stands for nano-sized HZSM-5) in methane dehydroaromatization(MDA)reaction has been performed with periodic CH4-H2 switch at 1033-1073 K for more than 1000 h.During this test,methane conversion ranges from 13% to 16%,and mean yield to aromatics(i.e.benzene and naphthalene) exceeds 10%.N2-physisorption,XRD,NMR and TPO measurements were performed for the used Mo/HZSM-5 catalysts and coke deposition,and the results revealed that the periodic hydrogenation can effectively suppress coke deposition by removing the inert aromatic-type coke,thus ensuring Mo/HZSM-5 partly maintained its activity even in the presence of large amount of coke deposition.The effect of zeolite particle size on the catalytic activity was also explored,and the results showed that the nano-sized zeolite with low diffusion resistance performed better.It is recognized that the size effect was enhanced by reaction time,and it became more remarkable in a long-term MDA reaction even at a low space velocity. | Changyong Sun Guangzong Fang Xiaoguang Guo Yuanli Hu Shuqi Ma Tianhua Yang Jie Han Hao Ma Dali Tan Xinhe Bao | 2015 | Journal of Energy Chemistry2015，24，3： | 6 |
| 13 | Genetic analysis of leaffolder resistance in rice显示文摘A double haploid(DH)population,which consists of 120 lines derived from anther culture of a typical indica and japonica hybrid 'CJ06'/'TN1',was used to investigate the genetic basis for rice leaffolder resistance.Using a constructed molecular linkage map,five QTLs for rolled leaves were detected on chromosomes 1,2,3,4,and 8.The positive alleles from CJ06 on chromosomes 3,4,and 8 in-creased the resistance to rice leaffolder,and the alleles from TN1 on chromosomes 1 and 2 also enhanced resistance to leaffolder.The interactions between QTLs were identified and tested,and four conditional interactions were acquired for resistance to rice leaffolder.These loci were located on chromosomes 2,9,10,and 11,respectively.QTL pyramiding indicated that the positive alleles affect resistance to leaffolder.The prospective application of this data in rice breeding was also discussed. | Yuchun Rao Guojun Dong Dali Zeng Jiang Hu Longjun Zeng Zhengyu Gao Guanghen Zhang Longbiao Guo Qian Qian | 2010 | Journal of Genetics and Genomics2010，37，5： | 6 |
| 14 | Quantitative Trait Loci Mapping of Flag-leaf Ligule Length in Rice and Alignment with ZmLG1 Gene显示文摘A doubled haploid(DH) population,which consists of 120 lines derived from anther culture of a typical indica and japonica hybrid 'CJ06'/'TN1',was used in this study.Ligule lengths of flag leaf were investigated for quantitative trait loci(QTL) mapping using the DH population.Five QTLs(qLL-2,qLL-4,qLL-6,qLL-10 and qLL-12) controlling the ligule length(LL) were detected on chromosomes 2,4,6,10 and 12,with the variances explained 11.4%,13.6%,27.8%,22.1% and 11.0%,respectively.Using four known genes of ZmGL1,ZmGL2,ZmGL3 and ZmGL4 in maize from the MaizeGDB,their homologs in rice were aligned and integrated into the existing simple sequence repeats linkage map by in silico mapping.A ZmLG1 homolog gene,OsLG1 encoding a squamosa promoter binding protein,was located between the markers RM255 and RM280,which is just identical to the interval of qLL-4 on the long arm of chromosome 4.The results are beneficial to dissection of the ligule molecular mechanism and the study of cereal evolution. | Dali Zeng Jiang Hu Guojun Dong Jian Liu Longjun Zeng Guangheng Zhang Longbiao Guo Yihua Zhou Qian Qian | 2009 | Journal of Integrative Plant Biology2009，51，4： | 6 |

| 16 | The pleiotropic ABNORMAL FLOWER AND DWARF1 affects plant height, floral development and grain yield in rice显示文摘Moderate plant height and successful establishment of reproductive organs play pivotal roles in rice grain production. The molecular mechanism that controls the two aspects remains unclear in rice. In the present study,we characterized a rice gene, ABNORMAL FLOWER AND DWARF1(AFD1) that determined plant height, floral development and grain yield. The afd1 mutant showed variable defects including the dwarfism, long panicle, low seed setting and reduced grain yield. In addition, abnormal floral organs were also observed in the afd1 mutant including slender and thick hulls, and hull-like lodicules.AFD1 encoded a DUF640 domain protein and was expressed in all tested tissues and organs. Subcellular localization showed AFD1-green fluorescent fusion protein(GFP) was localized in the nucleus. Meantime, our results suggested that AFD1 regulated the expression of cell division and expansion related genes. | Deyong Ren Yuchun Rao Liwen Wu Qiankun Xu Zizhuang Li Haiping Yu Yu Zhang Yujia Leng Jiang Hu Li Zhu Zhenyu Gao Guojun Dong Guangheng Zhang Longbiao Guo Dali Zeng Qian Qian | 2016 | Journal of Integrative Plant Biology2016，58，6： | 4 |

| 18 | Rapid Creation of New Photoperiod-/Thermo-Sensitive Genic Male-Sterile Rice Materials by CRISPR/Cas9 System显示文摘Rice is an important food crop in China, and the development of hybrid rice is a crucial way to increase grain yield. The creation of dual-purpose nuclear-sterile lines for two-line hybrid breeding has become vital for commercial rice breeding. We constructed the pC1300-2 x35 S::Cas9-sgRNA^(PTGMS2-1) expression vector for editing the male fertility gene PTGMS2-1 in two widely compatible rice varieties, 93-11 and Huazhan, by using the CRISPR/Cas9 system. We obtained the marker-free photoperiod-/thermo-sensitive genic male-sterile(P/TGMS) lines in T_1 generation. According to the experiments in phytotron with four temperature and photoperiod treatments, we found the temperature is the main factor for restoring the pollen fertility of ptgms2-1 mutants in 93-11 and Huazhan, and the photoperiod also has some effects on pollen fertility in two different rice backgrounds. The application of cultivating new male-sterile lines by genome editing system will significantly accelerate the rice breeding process. | SHEN Lan DONG Guojun ZHANG Yu HU Guocheng ZHANG Qiang HU Guanglian XU Bo REN Deyong HU Jiang ZHU Li GAO Zhenyu ZHANG Guangheng GUO Longbiao ZENG Dali QIAN Qian | 2019 | Rice science2019，26，2： | 3 |
| 19 | Ecosystem service delivery in Karst landscapes: anthropogenic perturbation and recovery显示文摘Covering extensive parts of China, Karst landscapes are exceptional because rapid and intensive land use change has caused severe ecosystem degradation within only the last 50 years. The twentieth century intensification in food production through agriculture has led to a rapid deterioration of soil quality, evidenced in reduced crop production and rapid loss of soil. In many areas, a tipping point appears to have been passed as basement rock is exposed and 'rocky desertification' dominates. Through the establishment of the 'Soil processes and ecological services in the karst critical zone of SW China'(SPECTRA)Critical Zone Observatory(CZO) we will endevaour to understand the fundmental processes involved in soil production and erosion, and investigate the integrated geophysical-geochemical-ecological responses of the CZ to perturbations. The CZ spans a gradient from undisturbed natural vegetation through human perturbed landscapes.We seek to understand the importance of heterogeneity insurface and below-ground morphology and flow pathways in determining the spatial distribution of key stocks(soil,C, vegetation, etc.) and their control on ecosystem service delivery. We will assess the extent to which the highly heterogeneous critical zone resources can be restored to enable sustainable delivery of ecosystem services. This paper presents the CZO design and initial assessment of soil and soil organic carbon stocks and evidence for their stability based on caesium-137(^(137) Cs) data. | Timothy Quine Dali Guo Sophie M.Green Chenglong Tu Iain Hartley Xinyu Zhang Jennifer Dungait Xuefa Wen Zhaoliang Song Hongyan Liu Heather Buss Timothy Barrows Richard Evershed Penny Johnes Jeroen Meersmans | 2017 | Acta Geochimica2017，36，3： | 3 |
| 20 | Identification and characterization of Mini1, a gene regulating rice shoot development显示文摘The aerial parts of higher plants are generated from the shoot apical meristem(SAM). In this study, we isolated a small rice(Oryza sativa L.) mutant that showed premature termination of shoot development and was named mini rice 1(mini1). The mutant was first isolated from a japonica cultivar Zhonghua11(ZH11) subjected to ethyl methanesulfonate(EMS)treatment. With bulked segregant analysis(BSA) and map-based cloning method, Mini1 gene was finally fine-mapped to an interval of 48.6 kb on chromosome 9. Sequence analyses revealed a single base substitution from G to A was found in the region, which resulted in an amino acid change from Gly to Asp.The candidate gene Os09g0363900 was predicted to encode a putative adhesion of calyx edges protein ACE(putative HOTHEAD precursor) and genetic complementation experiment confirmed the identity of Mini1. Os09g0363900 contains glucose-methanol-choline(GMC) oxidoreductase and NAD(P)-binding Rossmann-like domain, and exhibits high similarity to Arabidopsis HOTHEAD(HTH). Expression analysis indicated Mini1 was highly expressed in young shoots but lowly in roots and the expression level of most genes involved in auxin biosynthesis and signal transduction were reduced in mutant.We conclude that Mini1 plays an important role in maintaining SAM activity and promoting shoot development in rice. | Yunxia Fang Jiang Hu Jie Xu Haiping Yu Zhenyuan Shi Guosheng Xiong Li Zhu Dali Zeng Guangheng Zhang Zhenyu Gao Guojun Dong Meixian Yan Longbiao Guo Yonghong Wang Qian Qian | 2015 | Journal of Integrative Plant Biology2015，57，2： | 3 |
