| 1 | MicroRNAs in tomato plants显示文摘MicroRNAs (miRNAs) are a specialized class of small silencing RNAs that regulate gene expression in eukaryotes.In plants,miRNAs negatively regulate target mRNAs containing a highly complementary sequence by either mRNA cleavage or translational repression.As a model plant to study fleshy fruit ripening,miRNA studies in tomato have made great progress recently.MiRNAs were predicted to be involved in nearly all biological processes in tomato,particularly development,differentiation,and biotic and abiotic stress responses.Surprisingly,several miRNAs were verified to be involved in tomato fruit ripening and senescence.Recent studies suggest that miRNAs are related to host-virus interactions,which raises the possibility that miRNAs can be used as diagnostic markers for response to virus infection in tomato plants.In this review,we summarize our current knowledge systematically and advance future directions for miRNA research in tomato. | ZUO JinHua WANG YunXiang LIU HaiPing MA YuanZheng JU Zheng ZHAI BaiQiang FU DaQi ZHU Yi LUO YunBo ZHU BenZhong | 2011 | Science China(Life Sciences)2011，54，7： | 13 |
| 2 | Virus-induced Gene Silencing in Eggplant(Solanum melongena)显示文摘Eggplant(Solanum melongena)is an economically important vegetable requiring investigation into its various genomic functions.The current limitation in the investigation of genomic function in eggplant is the lack of effective tools available for conducting functional assays.Virus-induced gene silencing(VIGS)has played a critical role in the functional genetic analyses.In this paper,TRV-mediated VIGS was successfully elicited in eggplant.We first cloned the CDS sequence of PDS(PHYTOENE DESATURASE) in eggplant and then silenced the PDS gene.Photo-bleaching was shown on the newly-developed leaves four weeks after agroinoculation,indicating that VIGS can be used to silence genes in eggplant.To further illustrate the reliability of VIGS in eggplant,we selected Chl H,Su and CLA1 as reporters to elicit VIGS using the high-pressure spray method.Suppression of Chl H and Su led to yellow leaves,while the depletion of CLA1 resulted in albino.In conclusion,four genes,PDS,Chl H,Su(Sulfur),CLA1,were down-regulated significantly by VIGS,indicating that the VIGS system can be successfully applied in eggplant and is a reliable tool for the study of gene function. | Haiping Liu Daqi Fu Benzhong Zhu Huaxue Yan Xiaoying Shen Jinhua Zuo Yi Zhu Yunbo Luo | 2012 | Journal of Integrative Plant Biology2012，54，6： | 11 |
| 3 | A NAC transcription factor, NOR-like1, is a new positive regulator of tomato fruit ripening显示文摘Ripening of the model fruit tomato(Solanum lycopersicum)is controlled by a transcription factor network including NAC(NAM,ATAF1/2,and CUC2)domain proteins such as No-ripening(NOR),SlNAC1,and SlNAC4,but very little is known about the NAC targets or how they regulate ripening.Here,we conducted a systematic search of fruit-expressed NAC genes and showed that silencing NOR-like1(Solyc07g063420)using virus-induced gene silencing(VIGS)inhibited specific aspects of ripening.Ripening initiation was delayed by 14 days when NOR-like1 function was inactivated by CRISPR/Cas9 and fruits showed obviously reduced ethylene production,retarded softening and chlorophyll loss,and reduced lycopene accumulation.RNA-sequencing profiling and gene promoter analysis suggested that genes involved in ethylene biosynthesis(SlACS2,SlACS4),color formation(SlGgpps2,SlSGR1),and cell wall metabolism(SlPG2a,SlPL,SlCEL2,and SlEXP1)are direct targets of NOR-like1.Electrophoretic mobility shift assays(EMSA),chromatin immunoprecipitation-quantitative PCR(ChIP-qPCR),and dual-luciferase reporter assay(DLR)confirmed that NOR-like1 bound to the promoters of these genes both in vitro and in vivo,and activated their expression.Our findings demonstrate that NOR-like1 is a new positive regulator of tomato fruit ripening,with an important role in the transcriptional regulatory network. | Ying Gao Wei Wei Xiaodan Zhao Xiaoli Tan Zhongqi Fan Yiping Zhang Yuan Jing Lanhuan Meng Benzhong Zhu Hongliang Zhu Jianye Chen Cai-Zhong Jiang Donald Grierson Yunbo Luo Da-Qi Fu | 2018 | Horticulture Research2018，5，1： | 9 |
| 4 | Diversity and redundancy of the ripening regulatory networks revealed by the fruitENCODE and the new CRISPR/Cas9 CNR and NOR mutants显示文摘Tomato is considered as the genetic model for climacteric fruits,in which three major players control the fruit ripening process:ethylene,ripening transcription factors,and DNA methylation.The fruitENCODE project has now shown that there are multiple transcriptional circuits regulating fruit ripening in different species,and H3K27me3,instead of DNA methylation,plays a conserved role in restricting these ripening pathways.In addition,the function of the core tomato ripening transcription factors is now being questioned.We have employed CRISPR/Cas9 genome editing to mutate the SBP-CNR and NAC-NOR transcription factors,both of which are considered as master regulators in the current tomato ripening model.These plants only displayed delayed or partial non-ripening phenotypes,distinct from the original mutant plants,which categorically failed to ripen,suggesting that they might be gain-of-function mutants.Besides increased DNA methylation genome-wide,the original mutants also have hyper-H3K27me3 in ripening gene loci such as ACS2,RIN,and TDR4.It is most likely that multiple genetic and epigenetic factors have contributed to their strong non-ripening phenotypes.Hence,we propose that the field should move beyond these linear and twodimensional models and embrace the fact that important biological processes such as ripening are often regulated by highly redundant network with inputs from multiple levels. | Ying Gao Ning Zhu Xiaofang Zhu Meng Wu Cai-Zhong Jiang Donald Grierson Yunbo Luo Wei Shen Silin Zhong Da-Qi Fu Guiqin Qu | 2019 | Horticulture Research2019，6，1： | 7 |
| 5 | Tomato DCL2b is required for the biosynthesis of 22-nt small RNAs, the resulting secondary siRNAs, and the host defense against ToMV显示文摘The tomato encode four functional DCL families,of which DCL2 is poorly studied.Here,we generated loss-of-function mutants for a tomato DCL2 gene,dcl2b,and we identified its major role in defending against tomato mosaic virus in relation to both natural and manual infections.Genome-wide small RNA expression profiling revealed that DCL2b was required for the processing 22-nt small RNAs,including a few species of miRNAs.Interestingly,these DCL2b-dependent 22-nt miRNAs functioned similarly to the DCL1-produced 22-nt miRNAs in Arabidopsis and could serve as triggers to generate a class of secondary siRNAs.In particular,the majority of secondary siRNAs were derived from plant defense genes when the plants were challenged with viruses.We also examined differentially expressed genes in dcl2b through RNA-seq and observed that numerous genes were associated with mitochondrial metabolism and hormone signaling under virus-free conditions.Notably,when the loss-of-function dcl2b mutant was challenged with tomato mosaic virus,a group of defense response genes was activated,whereas the genes related to lipid metabolism were suppressed.Together,our findings provided new insights into the roles of tomato DCL2b in small RNA biogenesis and in antiviral defense. | Tian Wang Zhiqi Deng Xi Zhang Hongzheng Wang Yu Wang Xiuying Liu Songyu Liu Feng Xu Tao Li Daqi Fu Benzhong Zhu Yunbo Luo Hongliang Zhu | 2018 | Horticulture Research2018，5，1： | 4 |
| 6 | Lycopene Accumulation Affects the Biosynthesis of Some Carotenoid-related Volatiles Independent of Ethylene in Tomato显示文摘For elucidating the regulatory mechanism of ethylene on carotenoid-related volatiles (open chain) compounds and the relationship between lycopene and carotenoid-related volatiles, transgenic tomato fruits in which ACC synthase was suppressed were used. The transgenic tomato fruit showed a significant reduction of lycopene and aroma volatiles with low ethylene production. 6-methyl-5-hepten-2-one, 6-methyl-5-hepten-2-ol and geranylacetone, which were suspected to be lycopene degradation products, were lower than those in wild type tomato fruits. In order to identify whether lycopene accumulation effects the biosynthesis of some carotenoid-related volatiles independent of ethylene in tomato or not, the capability of both wild type and transgenic tomato fruits discs to convert lycopene into carotenoid-related volatiles was evaluated. The data showed that external lycopene could convert into 6-methyl-5-hepten-2-one and 6-methyl-5-hepten-2-ol in vivo, indicating that the strong inhibition of ethylene production had no effect on enzymes in the biosynthesis pathway of some carotenoid-related volatiles. Therefore, in ACS-suppression transgenic tomato fruits, the low levels of 6-methyl-5-hepten-2-one, 6-methyl-5-hepten-2-ol was due to decreased lycopene accumulation, not ethylene production. Ethylene only affected the accumulation of lycopene, and then indirectly influenceed the level of lycopene-related volatiles. | Hongyan Gao Hongliang Zhu Yi Shao Anjun Chen Chengwen Lu Benzhong Zhu Yunbo Luo | 2008 | Journal of Integrative Plant Biology2008，50，8： | 3 |
| 7 | Deciphering Ascorbic Acid Regulatory Pathways in Ripening Tomato Fruit Using a Weighted Gene Correlation Network Analysis Approach显示文摘Genotype is generally determined by the co-expression of diverse genes and multiple regulatory pathways in plants.Gene co-expression analysis combining with physiological trait data provides very important information about the gene function and regulatory mechanism.L-Ascorbic acid(AsA),which is an essential nutrient component for human health and plant metabolism,plays key roles in diverse biological processes such as cell cycle,cell expansion,stress resistance,hormone synthesis,and signaling.Here,we applied a weighted gene correlation network analysis approach based on gene expression values and AsA content data in ripening tomato(Solanum lycopersicum L.)fruit with different AsA content levels,which leads to identifcation of AsA relevant modules and vital genes in AsA regulatory pathways.Twenty-four modules were compartmentalized according to gene expression profling.Among these modules,one negatively related module containing genes involved in redox processes and one positively related module enriched with genes involved in AsA biosynthetic and recycling pathways were further analyzed.The present work herein indicates that redox pathways as well as hormone-signal pathways are closely correlated with AsA accumulation in ripening tomato fruit,and allowed us to prioritize candidate genes for follow-up studies to dissect this interplay at the biochemical and molecular level. | Chao Gao Zheng Ju Shan Li Jinhua Zuo Daqi Fu Huiqin Tian Yunbo Luo Benzhong Zhu | 2013 | Journal of Integrative Plant Biology2013，55，11： | 3 |

| 19 | Nanozyme Enhanced Colorimetric Immunoassay for Naked-Eye Detection of Salmonella Enteritidis显示文摘Salmonella Enteritidis is a major public health threat of global proportions,while it is still a serious challenge to develop point-of-care detection assay.In this study,nanozymes(Fe-MOF nanoparticles)were successfully synthesized and applied as signal in a colorimetric immunoassay for naked-eye detection of Salmonella Enteritidis.After optimization,the proposed assay was able to detect Salmonella Enteritidis with a detection limit of 34 CFU/mL.The coefficients of variation(CV)of the test were less than 7.0%after 30 days storage at 4°C.The estimated recoveries in milk samples of the colorimetric immu-noassay range from 94.68 to 124%,which indicated the developed method is capable of detecting Salmonella Enteritidis in real samples.This method provides a potential platform for Salmonella detection with naked eyes,which has a significant application value for foodborne pathogen analysis at the point-of-care. | Nan Cheng Chengzhou Zhu Yinling Wang Dan Du Mei-Jun Zhu Yunbo Luo Wentao Xu Yuehe Lin | 2019 | Journal of Analysis and Testing2019，3，1： | 1 |
| 20 | Computational identification of microRNAs and their targets in wheat (Triticum aestivum L.)显示文摘microRNAs (miRNAs) are a class of endogenous, non-coding, short (~21 nt) RNAs directly involved in regulating gene expression at the post-transcriptional level. Previous reports have noted that plant miRNAs in the plant kingdom are highly conserved, which provides the foundation for identification of conserved miRNAs in other plant species through homology alignment. Conserved miRNAs in wheat are identified using EST (Expressed Sequence Tags) and GSS analysis. All previously known miRNAs in other plant species were blasted against wheat EST and GSS sequences to select novel miRNAs in wheat by a series of filtering criteria. From a total of 37 conserved miRNAs belonging to 18 miRNA families 10 conserved miRNAs comprising 4 families were reported in wheat. MiR395 is found to be a special family, because three members belonging to the same miR395 family are clustered together, similar to animal miRNAs. MiRNA targets are transcription factors involved in wheat growth and development, metabolism,and stress responses. | HAN YouSheng, LUAN FuLei, ZHU HongLiang, SHAO Yi, CHEN AnJun, LU ChengWen, LUO YunBo & ZHU BenZhong Laboratory of Fruit Biotechnology, College of Food Science and Nutritional Engineering, China Agricultural University, Beijing 100083, China | 2009 | Science China(Life Sciences)2009，52，11： | 1 |
