| 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 | Developing disease-resistant thermosensitive male sterile rice by multiplex gene editing显示文摘High-quality and disease-resistant male sterile lines have great potential for applications in hybrid rice breeding.We introduced specific mutations into the TMS5,Pi21,and Xa13 genes in Pinzhan intermediate breeding material using the CRISPR/Cas9 multiplex genome editing system.We found that the transgenefree homozygous triple tms5/pi21/xa13 mutants obtained in the T1 generation displayed characteristics of thermosensitive genic male sterility(TGMS)with enhancedresistance to rice blast and bacterial blight.Our study provides a convenient and effective way of converting breeding intermediate material into TGMS lines through multiplex gene editing,which could significantly accelerate the breeding of sterile lines. | Sanfeng Li Lan Shen Ping Hu Qing Liu Xudong Zhu Qian Qian Kejian Wang Yuexing Wang | 2019 | Journal of Integrative Plant Biology2019，61，12： | 11 |
| 4 | 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 |
| 5 | MULTI-TILLERING DWARF1, a new allele of BRITTLE CULM 12, affects plant height and tiller in rice显示文摘Plant height and tillering are crucial factors determining rice plant architecture and influencing rice grain production. In this study, multi-tillering dwarf1(mtd1), a stable multi-tiller and dwarf mutant, was screened from the ethylmethane sulfonate-treated japonica rice variety Wuyunging7. Compared with the wild type, mtd1 mutant exhibited pleiotropic phenotypes, including dwarfism, more tillers, brittle culms and delayed heading date.By employing map-based cloning strategy, the gene MTD1 was finally mapped to an approximately 66-kb region on the short arm of chromosome 9. Sequencing results showed that the gene LOC_Os09g02650(BC12) in mtd1 mutant had a single nucleotide substitution(G to A), which generated a premature translation stop. Over-expressing MTD1/BC12 coding sequence rescued all the phenotypes of mtd1 mutants including plant height and tillers, which confirms that BC12 is the mutated gene in mtd1 mutant.Quantitative reverse transcription-PCR analysis showed that MTD1/BC12 could negatively regulate the expression of MONOCULM 1, IDEAL PLANT ARCHITECTURE1 and Tillering and Dwarf 1, and control rice tillering. Remarkably, a-amylase activity analysis and gibberellic acid(GA)treatment showed that the dwarf phenotype of mtd1 mutant was dependent on GA biosynthesis pathway. These results facilitated to further uncover the molecular mechanism of the growth and development in rice. | Haiping Yu Deyong Ren Yangzhou Zhu Jiangmin Xu Yuexing Wang Ruifang Liu Yunxia Fang Zhenyuan Shi Jiangjie Pan Mei Lu Bojun Ma Jiang Hu Yuchun Rao | 2016 | Science Bulletin2016，61，23： | 3 |
| 6 | Tracking the multiple-step formation of an iron(Ⅲ) complex and its application in photodynamic therapy for breast cancer显示文摘A tandem reaction of pyridin-2-ylmethanamine(L1′) with 8-hydroxyquinoline-2-carbaldehyde(HL1) assisted by FeCl_3 was observed to give the new nitrogen heterocycle HL3(HL3=2-(imidazo[1,5-a]pyridin-3-yl)quinolin-8-ol) as its Fe(Ⅲ) complex,[Fe(L3)Cl_2](Fe1). Electrospray ionization mass spectrometry(ESI-MS) reveals its formation involves three steps:(1) coordination of both HL1 and L1′ to Fe,(2) aldehyde-amine coupling, and(3) ring closure. The results of electronic absorption spectroscopy, cyclic voltammetry, and density functional theory(DFT) calculations show the proximity of the optical transition energy to that of the excitation of ~3O_2 to ~1O_2, which prompted us to explore its application as a photosensitizer for photodynamic therapy(PDT). Photo-toxicity studies show that Fe1 exhibits the highest anti-proliferation efficiency in human breast cancer MDA-MB-231 cells under light irradiation. Moreover, studies with orthotopic models of breast cancer further expounded the anti-tumor activity of Fe1 with no significant toxicity to other organs and low retention in the body. | Zhong-Hong Zhu Qian Hu Hui-Ling Pan Yuexing Zhang Haibing Xu Mohamedally Kurmoo Jin Huang Ming-Hua Zeng | 2019 | Science China Chemistry2019，62，6： | 2 |

| 8 | Identification of natural allelic variation in TTL1 controlling thermotolerance and grain size by a rice super pan-genome∞显示文摘Continuously increasing global temperatures present great challenges to food security.Grain size,one of the critical components determining grain yield in rice(Oryza sativa L.),is a prime target for genetic breeding.Thus,there is an immediate need for genetic improvement in rice to maintain grain yield under heat stress.However,quantitative trait loci(QTLs)endowing heat stress tolerance and grain size in rice are extremely rare.Here,we identified a novel negative regulator with pleiotropic effects,Thermo‐Tolerance and grain Length 1(TTL1),from the super pan‐genomic and transcriptomic data.Loss‐of‐function mutations in TTL1 enhanced heat tolerance,and caused an increase in grain size by coordinating cell expansion and proliferation.TTL1 was shown to function as a transcriptional regulator and localized to the nucleus and cell membrane.Furthermore,haplotype analysis showed that hapL and hapS of TTL1 were obviously correlated with variations of thermotolerance and grain size in a core collection of cultivars.Genome evolution analysis of available rice germplasms suggested that TTL1 was selected during domestication of the indica and japonica rice subspecies,but still had much breeding potential for increasing grain length and thermotolerance.These findings provide insights into TTL1 as a novel potential target for the development of high‐yield and thermotolerant rice varieties. | Yarong Lin Yiwang Zhu Yuchao Cui Hongge Qian Qiaoling Yuan Rui Chen Yan Lin Jianmin Chen Xishi Zhou Chuanlin Shi Huiying He Taijiao Hu Chenbo Gu Xiaoman Yu Xiying Zhu Yuexing Wang Qian Qian Cuijun Zhang Feng Wang Lianguang Shang | 2023 | Journal of Integrative Plant Biology2023，65，12： | 0 |
| 9 | A Method for Effectively Overcoming Tight Functional Linkage Between Genes in Rice by CRISPR/Cas9 System显示文摘Anthocyanins are widely distributed in one or more parts of rice(Oryza sativa L.)plants,including seed coat,stigma,apiculus,leaf sheath and leaf blade,and are the main pigments used in rice to achieve different colors(Hou et al,2009;Aizza and Dornelas,2011).In rice,tissue-specific color traits(especially the color of apiculus,namely the lemma and palea of the spikelet)are not only important for rice variety identification but also important for linkage analysis and rice domestication research(Saitoh et al,2004;Fan et al,2007;Lin et al,2019).The apiculus color is controlled by the complementary functions of three pairs of dominant genes,C,A and P.Gene C(chromogen)is a pigment gene,which is the basic gene for producing pigments.Gene A(activator)activates gene C,converting the chromogen into anthocyanins,and gene P(purple)controls the distribution of anthocyanins in various organs(Reddy,1996;Sakamoto et al,2001). | LI Sanfeng SHEN Lan HU Ping WU Xianmei YUAN Qiaoling RAO Yuchun QIAN Qian WANG Kejian ZHU Xudong SHANG Lianguang WANG Yuexing | 2020 | Rice science2020，27，3： | 0 |

| 11 | Insulin-resistance and depression cohort data mining to identify nutraceutical related DNA methylation biomarker for type 2 diabetes显示文摘Insulin-resistance(IR)is one of the most important precursors of type 2 diabetes(T2D).Recent evidence suggests an association of depression with the onset of T2D.Accumu-lating evidence shows that depression and T2D share common biological origins,and DNA methylation examination might reveal the link between lifestyle,disease risk,and potential therapeutic targets for T2D.Here we hypothesize that integrative mining of IR and depression cohort data will facilitate predictive biomarkers identification for T2D.We utilized a newly proposed method to extract gene-level information from probe level data on genome-wide DNA methylation array.We identified a set of genes associated with IR and depression in clin-ical cohorts.By overlapping the IR-related nutraceutical-gene network with depression net-works,we identified a common subnetwork centered with Vitamin D Receptor(VDR)gene.Preliminary clinical validation of gene methylation set in a small cohort of T2D patients and controls was established using the Sequenome matrix-assisted laser desorption ionization-time flight mass spectrometry.A set of sites in the promoter regions of VDR showed a signifi-cant difference between T2D patients and controls.Using a logistic regression model,the optimal prediction performance of these sites was AUC Z 0.902,and an odds ratio Z 19.76.Thus,monitoring the methylation status of specific VDR promoter region might help stratify the high-risk individuals who could potentially benefit from vitamin D dietary sup-plementation.Our results highlight the link between IR and depression,and the DNA methyl-ation analysis might facilitate the search for their shared mechanisms in the etiology of T2D. | Fengji Liang Yuan Quan Andong Wu Ying Chen Ruifeng Xu Yuexing Zhu Jianghui Xiong | 2021 | Genes & Diseases2021，8，5： | 0 |
