| 1 | Construction of a cucumber genetic linkage map with SRAP markers and location of the genes for lateral branch traits显示文摘Using SRAP (sequence-related amplified polymorphism) markers a genetic linkage map of cucumber was constructed with a population consisting of 138 F2 individuals derived from a cross of the two cucumber lines, S06 and S52. In the survey of parental polymorphisms with 182 primer combinations, 64 polymorphism-revealing primer pairs were screened out, which generated totally 108 polymorphic bands with an average of 1.7 bands per primer pair and at most 6 bands from one primer pair. The constructed molecular linkage map included 92 loci, distributed in seven linkage groups and spanning 1164.2 cM in length with an average genetic distance of 12.6 cM between two neighboring loci. Based on this linkage map, the quantitative trait loci (QTL) for the lateral branch number (lbn) and the lateral branch average length (lbl) in cucumber were identified by QTLMapper1.6. A major QTL lbn1 located between ME11SA4B and ME5EM5 in LG2 could explain 10.63% of the total variation with its positively effecting allele from S06. A major QTL lbl1 located between DC1OD3 and DC1EM14 in LG2 could account for 10.38% of the total variation with its positively effecting allele from S06. | WANG Gang PAN Junsong LI Xiaozun HE Huanle WU Aizhong CAI Run | 2005 | Science China(Life Sciences)2005，48，3： | 24 |
| 2 | Construction of a BAC library from cucumber (Cucumis sativus L.) and identification of linkage group specific clones显示文摘A bacterial artificial chromosome (BAC) library consisting of 19,200 clones with an average insert size of 105 kb has been constructed from a cucumber (Cucumis sativus L.) inbred line S94,derived from a cultivar in North China. The entire library was equivalent to approximately 5 haploid cucumber genomes. To facilitate chromosome engineering and anchor the cucumber genetic linkage map to its chromosomes,15 sequence-characterized ampli?ed regions (SCAR) and seven simple sequence repeats (SSR) markers from each link-age group of cucumber were used to screen an ordered array of pooled BAC DNA with polymerase chain reaction (PCR). Fifteen mark-ers gave at least two positive clones. As a result,22 BAC clones representing 7 linkage groups of cucumber were identified,which further validated the genome coverage and utility of the library. This BAC library and linkage group specific clones provide essential resources for future research of the cucumber genome. | Yuan Guan Qi Chen Junsong Pan Zheng Li Huanle He Aizhong Wu Rentao Song Run Cai | 2008 | Progress in Natural Science:Materials International2008，18，2： | 7 |
| 3 | Quantitative trait locus analysis of lateral branch-related traits in cucumber(Cucumis sativus L.)using recombinant inbred lines显示文摘A group of 224 recombinant inbred lines (RILs) was derived from a narrow cross between 2 cucumber (Cucumis sativus L.) lines, namely, S94 (Northern China type with weak lateral branch growth potential and early lateral branch sprouting time) and S06 (Northern European type with strong lateral branch growth potential and late lateral branch sprouting time). These lines were then used for investigating lateral branch-related traits. A total of 36 quantitative trait loci (QTLs) were detected for the following 4 lateral branch-related traits: lateral branch average length (LBAL), lateral branch total length (LBTL), lateral branch number (LBN), and first lateral branch node (FLBN). Further, each QTL explained 3.1% (lbtl2.1, spring) to 32.3% (lbn2.3, spring) of the observed phenotypic variance. Eleven QTLs (lbal1.1, lbtl1.1, lbn1.2, flbn1.2, etc.) for different traits were found to be clustered on the e23m18d-ME23EM6c section (7.4 cM) of linkage group (LG) 1; further, 15 QTLs (lbal2.1, lbtl2.1, lbn2.1, flbn2.1, etc.) were found to be clustered on the S94A1-ME4SA4a section (13.9 cM) of LG2. Twenty-one QTLs explained more than 10% of the phenotypic variance. Moreover, lbtl1.3 (autumn, 26.2%, logarithm of odds (LOD) = 17.4; spring, 26.9%, LOD = 17.9) had stable position and contribution in both seasons. Several se-quence-anchor markers (CMBR40, F, CS30, S94A1, CSWTA11B, etc.) were closely linked with some QTLs for LBAL, LBTL, LBN, and FLBN, which can be used for the marker-assisted selection to improve the plant architecture in cucumber breeding. | JIANG Su YUAN XiaoJun PAN JunSong HE HuanLe CAI Run | 2008 | Science China(Life Sciences)2008，51，9： | 5 |
| 4 | Rapid isolation and immune profiling of SARS-CoV-2 specific memory B cell in convalescent COVID-19 patients via LIBRA-seq显示文摘B cell response plays a critical role against SARS-CoV-2 infection.However,little is known about the diversity and frequency of the paired SARS-CoV-2 antigen-specific BCR repertoire after SARS-CoV-2 infection.Here,we performed single-cell RNA sequencing and VDJ sequencing using the memory and plasma B cells isolated from five convalescent COVID-19 patients,and analyzed the spectrum and transcriptional heterogeneity of antibody immune responses.Via linking BCR to antigen specificity through sequencing(LIBRA-seq),we identified a distinct activated memory B cell subgroup(CD11c^(high) CD95^(high))had a higher proportion of SARS-CoV-2 antigen-labeled cells compared with memory B cells.Our results revealed the diversity of paired BCR repertoire and the non-stochastic pairing of SARS-CoV-2 antigen-specific immunoglobulin heavy and light chains after SARS-CoV-2 infection.The public antibody clonotypes were shared by distinct convalescent individuals.Moreover,several antibodies isolated by LIBRA-seq showed high binding affinity against SARS-CoV-2 receptor-binding domain(RBD)or nucleoprotein(NP)via ELISA assay.Two RBD-reactive antibodies C14646P3S and C2767P3S isolated by LIBRA-seq exhibited high neutralizing activities against both pseudotyped and authentic SARS-CoV-2 viruses in vitro.Our study provides fundamental insights into B cell response following SARS-CoV-2 infection at the single-cell level. | Bing He Shuning Liu Yuanyuan Wang Mengxin Xu Wei Cai Jia Liu Wendi Bai Shupei Ye Yong Ma Hengrui Hu Huicui Meng Tao Sun Yanling Li Huanle Luo Mang Shi Xiangjun Du Wenjing Zhao Shoudeng Chen Jingyi Yang Haipeng Zhu Yusheng Jie Yuedong Yang Deyin Guo Qiao Wang Yuwen Liu Huimin Yan Manli Wang Yao-Qing Chen | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 2 |
| 5 | E3 ligase FBXW7 aggravates TMPD-induced systemic lupus erythematosus by promoting cell apoptosis显示文摘Systemic lupus erythematosus(SLE)is a systemic autoimmune disease,and the pathogenesis of SLE has not been fully elucidated.The E3 ubiquitin ligase FBXW7 has been well characterized in cancer as a tumor suppressor that can promote the ubiquitination and subsequent degradation of various oncoproteins;however,the potential role of FBXW7 in autoimmune diseases is unclear.In the present study,we identified that FBXW7 is a crucial exacerbating factor for SLE development and progression in a mouse model induced by 2,6,10,14-tetramethylpentadecane(TMPD).Myeloid cell-specific FBXW7-deficient(Lysm+FBXW7f/f)C57BL/6 mice showed decreased immune complex accumulation,glomerulonephritis,glomerular mesangial cell proliferation,and basemembrane thickness in the kidney.Lysm+FBXW7f/f mice produced fewer anti-Sm/RNP and anti-ANA autoantibodies and showed a decreased MHC II expression in B cells.In Lysm+FBXW7f/f mice,we observed that cell apoptosis was reduced and that fewer CD11b+Ly6Chi inflammatory monocytes were recruited to the peritoneal cavity.Consistently,diffuse pulmonary hemorrhage(DPH)was also decreased in Lysm+FBXW7f/f mice.Mechanistically,we clarified that FBXW7 promoted TMPD-induced cell apoptosis by catalyzing MCL1 degradation through K48-linked ubiquitination.Our work revealed that FBXW7 expression in myeloid cells played a crucial role in TMPD-induced SLE progression in mice,which may provide novel ideas and theoretical support for understanding the pathogenesis of SLE. | Zhenlu Chong Chunjing Bao Jia He Tianxiao Chen Lijia Zhong Gaopeng Li Huanle Li Lutong Fang Yinjing Song Guoxiang Fu Xuyan Yang Lihua Lai Yang Liu Qingqing Wang | 2018 | Cellular & Molecular Immunology2018，15，12： | 2 |

| 7 | Study of micro-trichome (mict) reveals novel connections between transcriptional regulation of multicellular trichome development and specific metabolism in cucumber显示文摘Trichomes that cover the epidermis of aerial plant organs play multiple roles in plant protection.Compared with a unicellular trichome in model plants,the development mechanism of the multicellular trichome is largely unclear.Notably,variations in trichome development are often accompanied by defects in the biosynthesis of cuticle and secondary metabolites;however,major questions about the interactions between developmental differences in trichomes and defects in metabolic pathways remain unanswered.Here,we characterized the glabrous mutant mict/csgl1/cstbh via combined metabolomic and transcriptomic analyses to extend our limited knowledge regarding multicellular trichome development and metabolism in cucumber.Mict was found to be explicitly expressed within trichome cells.Transcriptomic analysis indicated that genes involved in flavonoid and cuticle metabolism are significantly downregulated in mict mutants.Further metabolomic analysis confirmed that flavonoids,lipids,and cuticle compositions are dramatically altered in mict mutants.Additional studies revealed that Mict regulates flavonoid,lipid,and cuticle biosynthesis by likely directly binding to downstream functional genes,such as CsTT4,CsFLS1,CsCER26,and CsMYB36.These findings suggest that specific metabolic pathways(e.g.,flavonoids and cuticle components)are co-regulated by Mict and provide insights into transcriptional regulation mechanisms of multicellular trichome development and its specific metabolism in cucumber. | Jian Pan Leyu Zhang Guanqun Chen Haifan Wen Yue Chen Hui Du Junlong Zhao Huanle He Hongli Lian Huiming Chen Jianxin Shi Run Cai Gang Wang Junsong Pan | 2021 | Horticulture Research2021，8，1： | 1 |
| 8 | Efficient Transposition of the Retrotransposon Tnt1 in Cucumber(Cucumis sativus L.)显示文摘Tnt1 is an active retrotransposon originally identified in tobacco(Nicotiana tabacum L.)(Grandbastien et al.,1989),but its transposition activity could be activated through tissue culture in other plant species.The insertions are stable and inheritable in the progeny,which has made it a valuable and versatile tool for developing insertional mutagenesis libraries in several plant species.Here,we explored its utility for mutagenesis in cucumber(Cucumis sativus L.).T_3 Tnt1 transgenic cucumber plants were subjected to tissue culture to regenerate self-pollinated progeny.With PCR and analyses and Southern hybridization,we found regenerated plants maintained the original Tnt1 insertion and created new insertions suggesting characteristic re-transposition activity of Tnt1 during this process.Using genome walking,some flanking sequences of Tnt1 insertions were recovered in regenerated plants.The results demonstrated that Tnt1 could be stably inherited and re-transposable during tissue culture in cucumber and that it is feasible to use for developing an insertional mutagenesis library for cucumber. | ZHANG Qi DU Hui LV Duo XIAO Tingting PAN Jian HE Huanle WANG Gang CAI Run WENG Yiqun PAN Junsong | 2018 | Horticultural Plant Journal2018，4，3： | 0 |
