1ABNORMAL 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 2020Science China(Life Sciences)2020,63,2:10
2The 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 2016Journal of Integrative Plant Biology2016,58,6:4
3Rapid 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 2019Rice science2019,26,2:3
4Genome-wide association study and transcriptome analysis reveal new QTL and candidate genes for nitrogen-deficiency tolerance in rice显示文摘The development of rice cultivars with improved nitrogen use efficiency(NUE)is desirable for sustainable agriculture.Achieving this goal depends in part on understanding how rice responds to low soil nitrogen(N)and identifying causative genes underlying this trait.To identify quantitative trait loci(QTL)or genes associated with low N response,we conducted a genome-wide association study(GWAS)using a diverse panel of 230 rice accessions and performed a transcriptomic investigation of rice accessions with differential responses to low N stress at two N levels.We detected 411 GWAS-associated genes in 5 QTL and 2722 differentially expressed genes in response to low N,of which 24 were identified by both methods and ranked according to gene annotations,literature queries,gene expression,and genetic diversity analysis.The large-scale datasets obtained from this study reveal low N-responsive characteristics and provide insights towards understanding the regulatory mechanisms of N-deficiency tolerance in rice,and the candidate genes or QTL would be valuable resources for increasing rice NUE via molecular biotechnology.Qing Li Xueli Lu Changjian Wang Lan Shen Liping Dai Jinli He Long Yang Peiyuan Li Yifeng Hong Qiang Zhang Guojun Dong Jiang Hu Guangheng Zhang Deyong Ren Zhenyu Gao Longbiao Guo Qian Qian Li Zhu Dali Zeng 2022The Crop Journal2022,10,4:3
5LRG1 maintains sterile lemma identity by regulating OsMADS6 expression in rice显示文摘Dear Editor,Spikelet is the unique structural unit of grass panicles with florets and diverse glume-like organs.In rice,a normal spikelet usually has two pairs of glume-like organs,including a pair of sterile lemmas and a pair of rudimentary glumes.Generally,the sterile lemma is considered to be the severely degenerated bract,but its origin is still controversial.Qiankun Xu Xiaoqi Yu Yuanjiang Cui Saisai Xia Dali Zeng Qian Qian Deyong Ren 2021Science China(Life Sciences)2021,64,7:2
6OsPPR9 encodes a DYW-type PPR protein that affects editing efficiency of multiple RNA editing sites and is essential for chloroplast development显示文摘Photosynthesis occurs mainly in chloroplasts,whose development is regulated by proteins encoded by nuclear genes.Among them,pentapeptide repeat(PPR)proteins participate in organelle RNA editing.Although there are more than 450 members of the PPR protein family in rice,only a few affect RNA editing in rice chloroplasts.Gene editing technology has created new rice germplasm and mutants,which could be used for rice breeding and gene function study.This study evaluated the functions of OsPPR9 in chloroplast RNA editing in rice.The osppr9 mutants were obtained by CRISPR/Cas9,which showed yellowing leaves and a lethal phenotype,with suppressed expression of genes associated with chloroplast development and accumulation of photosynthetic-related proteins.In addition,loss of OsPPR9 protein function reduces the editing efficiency of rps8-C182,rpoC2-C4106,rps14-C80,and ndhB-C611 RNA editing sites,which affects chloroplast growth and development in rice.Our data showed that OsPPR9 is highly expressed in rice leaves and encodes a DYW-PPR protein localized in chloroplasts.Besides,the OsPPR9 protein was shown to interact with OsMORF2 and OsMORF9.Together,our findings provide insights into the role of the PPR protein in regulating chloroplast development in rice.CHEN Chang-zhao WANG Ya-liang HE Meng-xing LI Zhi-wen SHEN Lan LI Qing REN Deyong HU Jiang ZHU Li ZHANG Guang-heng GAO Zhen-yu ZENG Da-li GUO Long-biao QIAN Qian ZHANG Qiang 2023Journal of Integrative Agriculture2023,22,4:0
7Identifi cation of targets and mechanisms for Eleutheroside E in the treatment of cancer显示文摘Eleutheroside E(EE)is a monomer compound isolated from Acanthopanax senticosus,which has functions of antifatigue,antioxidation,and immune regulation.However,the function of EE in inhibiting cancer has rarely been reported.In this study,we used bioinformatics to determine the role and mechanisms of EE in inhibiting breast cancer(BRCA),prostate cancer(PRAD),lung cancer(LUAD),and bladder cancer(BLCA).Finally,the MTT method was used to evaluate the inhibitory effect of EE on breast cancer MDA-MB-231 cells,and the target genes were determined by qRT-PCR.The results showed that the survival rate of MDA-MB-231 cells was reduced by 27.33%after 400μg/mL EE treatment.The results of qRT-PCR showed that EE down-regulated target genes in breast cancer cells,which was consistent with our predicted results.Moreover,our results indicated that EE may have impact on the transcription and translation of BLCA cells by targeting ADCY2,ADCY5 and JUN.In BRCA,we identified three targets for EE.In addition,EE affected DNA repair and the development of BRCA by affecting the expression of RAD51.In LUAD,we identified 9 targets for EE,8 of which were related to DNA repair.EE inhibited PRAD by targeting ADCY8.Our research was the first report on the targets and mechanisms of EE for suppressing cancer combined with clinical data.Our research also provides theoretical support for using EE to suppress cancer.Deyong Zeng Yi Xiong Yishu Yin Shan Shan Fangyuan Duan Xin Gao Chen Song Mengyao Liu Yingchun Zhang Weihong Lu 2022Journal of Future Foods2022,2,1:0
8Functional Analysis of Three Rice Chloroplast Transit Peptides显示文摘Chloroplast transit peptides(CTPs) can be used to transport non-chloroplastic proteins into the chloroplasts. Here, we studied the CTPs of three rice(Oryza sativa L.) chloroplast-localized proteins and found that their CTPs could be used to transport non-chloroplast-localized proteins into the chloroplasts. Fusion proteins lacking the CTP remained located in the cytoplasm. Furthermore, we constructed green fluorescent protein fusion vectors with the three CTPs and three non-chloroplast-localized proteins, Ghd10, MULTI-FLORET SPIKELET1(MFS1), and SHORTENED UPPERMOST INTERNODE 1(SUI1). After transforming these constructs into rice protoplasts, the fusion proteins all localized in the chloroplasts. Collectively, our results showed that these CTPs can transport non-chloroplast-localized proteins into the chloroplasts, and more importantly, these CTPs can be applied to engineer chloroplast metabolism.HE Lei CHEN Guang ZHANG Sen QIU Zhennan HU Jiang ZENG Dali ZHANG Guangheng DONG Guojun GAO Zhenyu REN Deyong SHEN Lan GUO Longbiao QIAN Qian ZHU Li 2019Rice science2019,26,1:0
9IL-1β regulates the mouse Fas ligand expression in corneal endothelial cells显示文摘Constitutively expressed Fas ligand (FasL) in several distinct epithelial cell types appears to protect tissues by inducing apoptosis of Fas+ immune cells during inflammatory reactions. To study the rela-tionship of FasL and inflammation process in cornea,we examined the effects of inflammatory cytokine IL-1β on the FasL production,expression and cytotoxic function in corneal endothelial cells. In this paper,we demonstrate that IL-1β inhibits the FasL production and expression in corneal endothelial cells. The promoter activities of FasL in these cells are reduced by IL-1β in a dose-dependent manner. Finally,we also find that IL-1β block the cytotoxic effects of FasL derived from corneal endothelial cells to the Fas+ target cells. These data support the view that FasL derived from corneal endothelial cells modulate inflammation within cornea.ZHANG Jie Yang Ke TAN DeYong ZENG JunYing Alan FINE 2007Chinese Science Bulletin2007,52,16:0
10Carotenoid isomerase regulates rice tillering and grain productivity by its biosynthesis pathway显示文摘Tillers are unique inflorescence-like branches in grasses,and their number determines the panicle number,plant architecture,and yield(Shang et al.,2021).Tiller formation mainly undergoes axillary meristem(AM)initiation and tiller bud outgrowth(Wang et al.,2018;Yan et al.,2023).The rice(Oryza sativa)KNOX gene OSH1 is expressed in AMs,and an osh1 mutant produces fewer tillers(Tanaka et al.,2015).Chaoqing Ding Zhengji Shao Yuping Yan Guangheng Zhang Dali Zeng Li Zhu Jiang Hu Zhenyu Gao Guojun Dong Qian Qian Deyong Ren 2024Journal of Integrative Plant Biology2024,66,2:0
11Effects of Space Flight on Expression of Key Proteins in Rice Leaves显示文摘As a unique form of abiotic stress, the environmental conditions of outer space are expected to induce changes in plant genomes, proteomes and metabolic pathways. However, the effect of outer space conditions on the overall physiology of plants at the protein level has yet to be reported. To investigate the effects of outer space conditions on the growth-and development-related physiological processes and metabolic pathways of rice different stages, the seeds of rice variety DN423 were sent into orbit for 12.5 d aboard the SJ-10 Returning Satellite, and then the seedlings of both treated and control rice were compared at the three-leaf stage(TLS) and tillering stage(TS). In addition to comparing plant growth and reactive oxygen species(ROS) levels, seedling proteomes were also compared using isobaric tags for relative and absolute quantitation(i TRAQ). Space flight increased TLS plant height by 20%, reduced and increased ROS levels of the TLS and TS seedlings, respectively, and affected the expression of 36 and 323 proteins in TLS and TS leaves, respectively. Furthermore, the functions of the differentially abundant proteins were mainly associated with metabolism, energy, and protein synthesis and degradation. These results suggested that the exposure of seeds to outer space conditions affects the subsequent abundance of key signaling proteins, gene expression, and the processes of protein synthesis and degradation, thereby affecting metabolic processes and promoting adaptation to the abiotic stress of outer space. As such, the present study sheds light on the effects of space flight on plants and contributes to a more comprehensive understanding of extraterrestrial biology.Zeng Deyong Cui Jie Yin Yishu Zhang Meng Shan Shan Gao Xin Zhang Yingchun Sun Yeqing Lu Weihong 2020Rice science2020,27,5:0
12LSL1 controls cell death and grain production by stabilizing chloroplast in rice显示文摘Lesion mutants can be valuable tools to reveal the interactions between genetic factors and environmental signals and to improve grain production.Here we identified a rice(Oryza sativa)mutant,lesion spotleaf1(lsl1),which produces necrotic leaf lesions throughout its life cycle.LSL1 encodes a protein of unknown function and belongs to a grass-specific clade.The lesion phenotype of the lsl1 mutant was sharply induced by shading,and its detached leaves incubated in 6-benzylamino purine similarly formed lesions in the dark.In addition,the lsl1 mutant exhibited reactive oxygen species accumulation and cell death.The terminal deoxynucleotidyl transferase d UTP nick end-labeling(TUNEL)and comet assays revealed that the lsl1 mutant contained severe DNA damage,resulting in reduced grain yield and quality.RNA sequencing,gene expression,and protein activity analyses indicate that LSL1 is required for chloroplast function.Furthermore,LSL1 interacts with Psa D and PAP10 to form a regulatory module that functions in chlorophyll synthesis and chloroplast development to maintain redox balance.Our results reveal that LSL1 maintains chloroplast structure,redox homeostasis,and DNA stability,and plays important roles in the interaction between genetic factors and environmental signals and in regulating grain size and quality.Deyong Ren Wei Xie Qiankun Xu Jiang Hu Li Zhu Guangheng Zhang Dali Zeng Qian Qian 2022Science China(Life Sciences)2022,65,11:0
13Genetic and environmental control of rice tillering显示文摘Increasing tiller number is a target of high-yield rice breeding. Identification of tiller-defect mutants and their corresponding genes is helpful for clarifying the molecular mechanism of rice tillering. Summarizing research progress on the two processes of rice tiller formation, namely the formation and growth of axillary meristem, this paper reviews the effects of genetic factors, endogenous hormones, and exogenous environment on rice tillering, finding that multiple molecular mechanisms and signal pathways regulating rice tillering cooperate rice tillering, and discusses future research objectives and application of its regulatory mechanism. Elucidation of theis mechanism will be helpful for breeding high-yielding rice cultivars with ideal plant type via molecular design breeding.Yuping Yan Chaoqing Ding Guangheng Zhang Jiang Hu Li Zhu Dali Zeng Qian Qian Deyong Ren 2023The Crop Journal2023,11,5:0
14Belief reliability modeling and analysis for planetary reducer considering multi-source uncertainties and wear显示文摘The planetary reducer is a common type of transmission mechanism,which can provide high transmission accuracy and has been widely used,and it is usually required with high reliability of transmission characteristics in practice.During the manufacturing and usage stages of planetary reducers,uncertainties are ubiquitous and wear is inevitable,which affect the transmission characteristics and the reliability of planetary reducers.In this paper,belief reliability modeling and analysis considering multi-uncertainties and wear are proposed for planetary reducers.Firstly,based on the functional principle and the influence of wear,the performance margin degradation model is established using the hysteresis error as the key performance parameter,where the degradation is mainly caused by the accumulated wear.After that,multi-source uncertainties are analyzed and quantified separately,including manufacturing errors,uncertainties in operational and environmental conditions,and uncertainties in performance thresholds.Finally,the belief reliability model is established based on the performance margin degradation model.A case study of a planetary reducer is applied and the reliability sensitivity analysis is implemented to show the practicability of the proposed method.The results show that the proposed method can provide some suggestions to the design and manufacturing phases of the planetary reducer.LI Yun JIANG Kaige ZENG Ting CHEN Wenbin LI Xiaoyang LI Deyong ZHANG Zhiqiang 2021Journal of Systems Engineering and Electronics2021,32,5:0
