| 3 | 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 |
| 4 | BEAK-SHAPED GRAIN 1/TRIANGULAR HULL 1,a DUF640 gene,is associated with grain shape,size and weight in rice显示文摘Grain shape and size both determine grain weight and therefore crop yield.However,the molecular mechanisms controlling grain shape and size are still largely unknown.Here,we isolated a rice mutant,beak-shaped grain1(bsg1),which produced beak-shaped grains of decreased width,thickness and weight with a loosely interlocked lemma and palea that were unable to close tightly.Starch granules were also irregularly packaged in the bsg1 grains.Consistent with the lemma and palea shapes,the outer parenchyma cell layers of these bsg1 tissues developed fewer cells with decreased size.Map-based cloning revealed that BSG1 encoded a DUF640 domain protein,TRIANGULAR HULL 1,of unknown function.Quantitative PCR and GUS fusion reporter assays showed that BSG1 was expressed mainly in the young panicle and elongating stem.The BSG1 mutation affected the expression of genes potentially involved in the cell cycle and GW2,an important regulator of grain size in rice.Our results suggest that BSG1 determines grain shape and size probably by modifying cell division and expansion in the grain hull. | YAN DaWei ZHOU Ya YE ShengHai ZENG LongJun ZHANG XiaoMing HE ZuHua | 2013 | Science China(Life Sciences)2013，56，3： | 20 |

| 7 | Characterization and mapping of a novel mutant sms1 (senescence and male sterility 1) in rice显示文摘Plant senescence plays diverse important roles in development and environmental responses.However,the molecular basis of plant senescence is remained largely unknown.A rice spontaneous mutant with the character of early senescence and male sterility (sms) was found in the breeding line NT10-748.In order to identify the gene SMS1 and the underlying mechanism,we preliminarily analyzed physiological and biochemical phenotypes of the mutant.The mutant contained lower chlorophyll content compared with the wild type control and was severe male sterile with lower pollen viability.Genetic analysis showed that the mutant was controlled by a single recessive gene.By the map-based cloning approach,we fine-mapped SMS1 to a 67 kb region between the markers Z3-4 and Z1-1 on chromosome 8 using 1,074 F2 recessive plants derived from the cross between the mutant sms1 (japonica) × Zhenshan 97 (indica),where no known gene involved in senescence or male sterility has been identified.Therefore the SMS1 gene will be a novel gene that regulates the two developmental processes.The further cloning and functional analysis of the SMS1 gene is under way. | Wenyi Yan Shenghai Ye Qingsheng Jin Longjun Zeng Yu Peng Dawei Yan Weibing Yang Donglei Yang Zuhua He Yanjun Dong Xiaoming Zhang | 2010 | Journal of Genetics and Genomics2010，37，1： | 6 |
| 8 | 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 |
| 9 | 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 |
| 10 | OsWR2 recruits HDA704 to regulate the deacetylation of H4K8ac in the promoter of OsABI5 in response to drought stress显示文摘Drought stress is a major environmental factor that limits the growth, development, and yield of rice(Oryza sativa L.). Histone deacetylases(HDACs) are involved in the regulation of drought stress responses. HDA704 is an RPD3/HDA1 class HDAC that mediates the deacetylation of H4K8(lysine 8of histone H4) for drought tolerance in rice. In this study, we show that plants overexpressing HDA704(HDA704-OE) are resistant to drought stress and sensitive to abscisic acid(ABA), whereas HDA704 knockout mutant(hda704) plants displayed decreased drought tolerance and ABA sensitivity.Transcriptome analysis revealed that HDA704 regulates the expression of ABA-related genes in response to drought stress. Moreover, HDA704 was recruited by a drought-resistant transcription factor,WAX SYNTHESIS REGULATORY 2(Os WR2), and co-regulated the expression of the ABA biosynthesis genes NINE-CIS-EPOXYCAROTENOID DIOXYGENASE 3(NCED3), NCED4, and NCED5 under drought stress. HDA704 also repressed the expression of ABA-INSENSITIVE 5(Os ABI5) and DWARF AND SMALL SEED 1(Os DSS1) by regulating H4K8ac levels in the promoter regions in response to polyethylene glycol 6000 treatment. In agreement, the loss of Os ABI5 function increased resistance to dehydration stress in rice. Our results demonstrate that HDA704 is a positive regulator of the drought stress response and offers avenues for improving drought resistance in rice. | Yalu Guo Yiqing Tan Minghao Qu Kai Hong Longjun Zeng Lei Wang Chuxiong Zhuang Qian Qian Jiang Hu Guosheng Xiong | 2023 | Journal of Integrative Plant Biology2023，65，7： | 1 |

| 12 | Amphibian-derived peptide homodimer OA-GL17d promotes skin wound regeneration through the miR-663a/TGF-β1/Smad axis显示文摘Background:Amphibian-derived peptides exhibit considerable potential in the discovery and development of new therapeutic interventions for clinically challenging chronic skin wounds.MicroRNAs(miRNAs)are also considered promising targets for the development of effective therapies against skin wounds.However,further research in this field is anticipated.This study aims to identify and provide a new peptide drug candidate,as well as to explore the underlying miRNA mechanisms and possible miRNA drug target for skin wound healing.Methods:A combination of Edman degradation,mass spectrometry and cDNA cloning were adopted to determine the amino acid sequence of a peptide thatwas fractionated from the secretion of Odorrana andersonii frog skin using gel-filtration and reversed-phase high-performance liquid chromatography.The toxicity of the peptide was evaluated by Calcein-AM/propidium iodide(PI)double staining against human keratinocytes(HaCaT cells),hemolytic activity against mice blood cells and acute toxicity against mice.The stability of the peptide in plasma was also evaluated.The prohealing potency of the peptide was determined by MTS,scratch healing and a Transwell experiment against HaCaT cells,full-thickness injury wounds and scald wounds in the dorsal skin of mice.miRNA transcriptome sequencing analysis,enzyme-linked immunosorbent assay,real-time polymerase chain reaction and western blotting were performed to explore the molecular mechanisms.Results:A novel peptide homodimer(named OA-GL17d)that contains a disulfide bond between the 16th cysteine residue of the peptide monomer and the sequence‘GLFKWHPRCGEEQSMWT’was identified.Analysis showed that OA-GL17d exhibited no hemolytic activity or acute toxicity,but effectively promoted keratinocyte proliferation and migration and strongly stimulated the repair of full-thickness injury wounds and scald wounds in the dorsal skin of mice.Mechanistically,OA-GL17d decreased the level of miR-663a to increase the level of transforming growth factor-β1(TGF-β1)and activate the subsequent TGF-β1/Smad signaling pathway,thereby resulting in accelerated skin wound re-epithelialization and granular tissue formation.Conclusions:Our results suggest that OA-GL17d is a new peptide drug candidate for skin wound repair.This study emphasizes the importance of exogenous peptides as molecular probes for exploring competing endogenous RNA mechanisms and indicates that miR-663a may be an effective target for promoting skin repair. | Yue Zhang Ying Wang Lin Zeng Yixiang Liu Huiling Sun Shanshan Li Siyu Wang Longjun Shu Naixin Liu Saige Yin Junsong Wang Dan Ni Yutong Wu Ying Yang Li He Buliang Meng Xinwang Yang | 2022 | Burns & Trauma2022，10，1： | 0 |
