| 1 | An efficient papaya leaf distortion mosaic potyvirus vector for virus-induced gene silencing in papaya显示文摘Papaya(Carica papaya L.)is regarded as an excellent model for genomic studies of tropical trees because of its short generation time and its small genome that has been sequenced.However,functional genomic studies in papaya depend on laborious genetic transformations because no rapid tools exist for this species.Here,we developed a highly efficient virus-induced gene silencing(VIGS)vector for use in papaya by modifying an artificially attenuated infectious clone of papaya leaf distortion mosaic virus(PLDMV;genus:Potyvirus),PLDMV-E,into a stable Nimble Cloning(NC)-based PLDMV vector,pPLDMV-NC,in Escherichia coli.The target fragments for gene silencing can easily be cloned into pPLDMV-NC without multiple digestion and ligation steps.Using this PLDMV VIGS system,we silenced and characterized five endogenous genes in papaya,including two common VIGS marker genes,namely,phytoene desaturase,Mg-chelatase H subunit,putative GIBBERELLIN(GA)-INSENSITIVE DWARF1A and 1B encoding GA receptors;and the cytochrome P450 gene CYP83B1,which encodes a key enzyme involved in benzylglucosinolate biosynthesis.The results demonstrate that our newly developed PLDMV VIGS vector is a rapid and convenient tool for functional genomic studies in papaya. | Decai Tuo Pu Yan Guangyuan Zhao Hongguang Cui Guopeng Zhu Yang Liu Xiukun Yang He Wang Xiaoying Li Wentao Shen Peng Zhou | 2021 | Horticulture Research2021，8，1： | 2 |

| 3 | A Nimble Cloning-compatible vector system for high-throughput gene functional analysis in plants显示文摘Plant expression vectors are essential tools for gene functional analysis and molecular plant breeding.The gene of interest is transferred to the vector by molecular cloning technology.Nimble Cloning is a newly developed molecular cloning method with the advantages of simplicity,efficiency,and standardization.In this study,we developed a'pNC'vector system that contains 55 Nimble Cloning-compatible vectors for functional analysis of genes in plants.These vectors contain the NC frame flanked by unique adapters for one-step and standardized Nimble Cloning.We demonstrate that the pNC vectors are convenient and effective for the functional analysis of plant genes,including the study of gene ectopic expression,protein subcellular localization,protein-protein interaction,gene silencing(RNAi),virus-induced gene silencing,promoter activity,and CRISPR-Cas9-mediated genome editing.The'pNC'vector system represents a high-throughput toolkit that can facilitate the large-scale analysis of plant functional genomics. | Pu Yan Decai Tuo Wentao Shen Haida Deng Peng Zhou Xinzheng Gao | 2023 | Plant Communications2023，4，2： | 0 |
