| 1 | CRISPR/Cas9-mediated base-editing system efficiently generates gain-of-function mutations in Arabidopsis显示文摘Dear Editor,The CRISPR/Cas9(clustered regularly interspaced short palindromic repeats/CRISPR associated protein 9)system is revolutionizing genome editing due to its high efficiency,low cost,design simplicity and versatility.However,introduction of a point mutation at a desired position remains a great challenge in plant genome engineering.Currently,point mutation in plants was achieved by incorporating | Yiyu Chen Zhiping Wang Hanwen Ni Yong Xu Qijun Chen Linjian Jiang | 2017 | Science China(Life Sciences)2017，60，5： | 40 |
| 2 | Generating broad-spectrum tolerance to ALS-inhibiting herbicides in rice by base editing显示文摘Herbicide-tolerant rice varieties generated by genome editing are highly desirable for weed control.We have used a cytosine base editor to create a series of missense mutations in the P171 and/or G628 codons of the acetolactate synthase(ALS)gene to confer herbicide tolerance in rice.The four different missense mutations in the P171 codon,P171S,P171A,P171Yand P171F,exhibited different patterns of tolerance towards five representative herbicides from five chemical families of ALS inhibitors.For example,P171S and P171A had lower levels of tolerance than P171Y and P171F to bispyribac but not to the other herbicides.Interestingly,a novel triple mutant(P171F/G628E/G629S)had the highest tolerance to all five tested herbicides.Field trials showed that both P171F and P171F/G628E/G629S could potentially be used with nicosulfuron.Our work illustrates an effective way of using base editing to generate herbicide tolerance in elite rice varieties. | Rui Zhang Sha Chen Xiangbing Meng Zhuangzhuang Chai Delin Wang Yuge Yuan Kunling Chen Linjian Jiang Jiayang Li Caixia Gao | 2021 | Science China(Life Sciences)2021，64，10： | 4 |
| 3 | Erratum to:Generating broad-spectrum tolerance to ALS-inhibiting herbicides in rice by base editing显示文摘This paper contains an error in Figure 2, where P171Y and P171A under treatment of pyroxsulam have a duplicated picture.This picture is for P171Y but not for P171A.We provide the correct picture for P171A as follows. This new picture does not affect the conclusion of this article. | Rui Zhang Sha Chen Xiangbing Meng Zhuangzhuang Chai Delin Wang Yuge Yuan Kunling Chen Linjian Jiang Jiayang Li Caixia Gao | 2022 | Science China(Life Sciences)2022，65，6： | 1 |
| 4 | Single-cell transcriptomics reveals cell type diversity of human prostate显示文摘Extensive studies have been performed to describe the phenotypic changes occurring during malignant transformation of the prostate.However,the cell types and associated changes that contribute to the development of prostate diseases and cancer remain elusive,largely due to the heterogeneous composition of prostatic tissues.Here,we conduct a comprehensive evaluation of four human prostate tissues by singlecell RNA sequencing(sc RNA-seq)to analyze their cellular compositions.We identify 18 clusters of cell types,each with distinct gene expression profiles and unique features;of these,one cluster of epithelial cells(Ep)is found to be associated with immune function.In addition,we characterize a special cluster of fibroblasts and aberrant signaling changes associated with prostate cancer(PCa).Moreover,we provide insights into the epithelial changes that occur during the cellular senescence and aging.These results expand our understanding of the unique functional associations between the diverse prostatic cell types and the contributions of specific cell clusters to the malignant transformation of prostate tissues and PCa development. | Yang Chen Peng Zhang Jinling Liao Jiwen Cheng Qin Zhang Tianyu Li Haiying Zhang Yonghua Jiang Fangxing Zhang Yanyu Zeng Linjian Mo Haibiao Yan Deyun Liu Qinyun Zhang Chunlin Zou Gong-Hong Wei Zengnan Mo | 2022 | Journal of Genetics and Genomics2022，49，11： | 0 |
| 5 | Programmed sequential cutting endows Cas9 versatile base substitution capability in plants显示文摘Dear Editors,CRISPR/Cas9-mediated genome editing techniques have triggered a revolution in biology research(Jinek et al.,2012).Cas9 coupled with guide RNAs cuts DNA at precise positions,and the resulting double stranded breaks(DSB)were effectively repaired by non-homologous end joining(NHEJ)pathway in higher eukaryotic cells,including animals and plants. | Wei Yang Wei Qi Yucai Li Jiyao Wang Yanmin Luo Dehui Ding Sudong Mo Bo Chen Yu Lu Huarong Li Linjian Jiang | 2021 | Science China(Life Sciences)2021，64，6： | 0 |
| 6 | Parasitic plant dodder(Cuscuta spp.):a new natural Agrobacterium-to-plant horizontal gene transfer species显示文摘Dear Editor,Horizontal gene transfer(HGT)has long been recognized as asexual means of DNA transfer between different species.Although HGT is common to prokaryotes,it remains uncommon in higher eukaryotic species(Beiko et al.,2005). | Yuexia Zhang Delin Wang Yubin Wang Huirong Dong Yuge Yuan Wei Yang Daowan Lai Mingcai Zhang Linjian Jiang Zhaohu Li | 2020 | Science China(Life Sciences)2020，63，2： | 0 |
