| 4 | 甘蔗NAD(P)H脱氢酶复合体O亚基基因克隆及其与甘蔗花叶病毒VPg互作显示文摘NAD(P)H脱氢酶(NDH)复合体介导循环电子传递,对于维持叶绿体高效的光合作用具有重要作用。甘蔗(Saccharum spp. hybrid)中NDH复合体应答及参与甘蔗花叶病毒(Sugarcane mosaic virus,SCMV)的侵染尚未见报道。本研究克隆了甘蔗NDH复合体的O亚基,命名为ScNdhO,其开放读码框(open reading frame,ORF)长度为471 bp,编码长度为156 aa的蛋白。生物信息学分析表明,ScNdhO为稳定的亲水性蛋白,不存在信号肽,无跨膜结构域;蛋白二级结构元件多为无规则卷曲,具有典型的NDH复合体O亚基结构域;系统进化树分析表明,该蛋白属于NDH复合体O亚基蛋白家族。实时荧光定量 PCR分析发现,ScNdhO基因的表达具有明显的组织特异性,在成熟甘蔗叶片中的表达量最高,在茎中的表达量最低,在根中几乎不表达;ScNdhO基因在SCMV侵染早期上调表达,后期下调表达。亚细胞定位分析表明,ScNdhO定位于叶绿体。酵母双杂交(yeast two hybrid,Y2H)和双分子荧光互补(bimolecular fluorescence complementation,BiFC)实验表明,ScNdhO与SCMV-VPg互作。推测ScNdhO被SCMV选择性利用,可能参与SCMV基因组复制及花叶病症状的产生。 | 翟玉山 赵贺 张海 邓宇晴 程光远 杨宗桃 王彤 彭磊 徐倩 董萌 徐景升 | 2019 | 作物学报2019，45，10： | 6 |
| 5 | 侵染广西甘蔗的1个SCMV分离物CP基因序列分析及地高辛标记探针制备显示文摘甘蔗花叶病毒(Sugarcane mosaic virus,SC- MV)引起的甘蔗花叶病是一种重要的世界性甘蔗病害,在我国各蔗区普遍发生,局部地区为害严重。本文报道侵染华南地区甘蔗的SCMV一个分离物CP基因片段克隆、序列分析、地高辛标记探针制备及其在病毒检测中应用的结果。 1 材料与方法 1.1 样品采集、病毒CP基因片段RT-PCR扩增、扩增产物回收及克隆测序自广西合浦田间采取表现典型花叶症状的甘蔗品种“新台糖22”病叶,华美(洛阳)生物工程公司总RNA抽提试剂盒(I)抽提总RNA。PCR引物 SCMV-F5:5'-GAAGAXGTYTTCCAYCAAFCXG- GAAC-3'(-18-+8,Y=C或T,X=T或A。 | 汤亚飞 宋晓兵 许东林 周国辉 | 2005 | 植物病理学报2005，35，S1： | 4 |
| 6 | 玉米矮花叶病毒分离物基因组克隆及多样性分析显示文摘玉米是重要的粮食和经济作物,在国民经济中占有重要地位。玉米矮花叶病毒(Sugercan mosaic virus,SCMV)广泛分布在世界各玉米主产区,严重威胁玉米的安全生产。系统研究SCMV的发生危害、遗传结构与进化机制,对病毒病的防治具有重要意义。从山西省4个玉米主产区采集122个玉米叶片样品(2015年62份,2016年60份)。经RT-PCR检测证实36个样品(2015年20个样品,2016年16个样品)为SCMV阳性,且广泛分布于山西省玉米各个产区。从这些阳性样品中分离、测序、克隆得到了一个新的SCMV分离物,该分离物(包括5’-UTR和3’-UTR端)基因组全长9 539 bp,编码3 063个氨基酸。该分离物与26个SCMV分离物(NCBI)进行一致率、系统发育分析表明SCMV存在较大遗传变异,27个分离物被划分为3个与地理位置无明显相关性的不同进化群体。选择压力分析表明,负向选择可能是SCMV遗传变异的原因之一。对变异位点统计分析发现,该结果将为评估SCMV在中国的流行病学特征奠定基础,有助于SCMV的长期可持续防控策略的制定。 | 张虎 景晓雅 孙柳清 崔爱民 张鹏华 单皓 陈伟 | 2019 | 中国农业科技导报2019，21，9： | 3 |
| 7 | 甘蔗ScCRT1基因克隆及其应答SCMV侵染分子机制的研究显示文摘钙网蛋白(calreticulin,CRT)在真核生物中广泛表达,是重要的分子伴侣和钙离子结合蛋白,参与调控Ca2+稳态、钙依赖信号、内质网质量控制、植物生长发育、免疫反应和逆境应答等多种生物学过程。甘蔗(Saccharum spp.hybrid)中CRT应答甘蔗花叶病毒(Sugarcane mosaic virus,SCMV)侵染尚未见报道。本研究从热带种Badila(S.officinarum)中克隆了1个CRT1/CRT2亚型的CRT编码基因,命名为ScCRT1。该基因开放读码框(open reading frame,ORF)长度为1281bp,编码长度为426aa的蛋白。生物信息学分析表明,ScCRT1具有典型的CRT蛋白结构域,为稳定的亲水性蛋白,其N端有一个信号肽,具有典型的跨膜结构域,C端有典型的内质网定位信号;二级结构多为无规则卷曲;系统进化树分析表明,该蛋白是典型的CRT蛋白,在单子叶和双子叶植物中具有明显的分化。亚细胞定位表明ScCRT1定位于内质网。实时荧光定量PCR分析发现,ScCRT1基因在甘蔗各组织中都有表达,在第8节间中的表达量最低,在心叶中的表达量较高;该基因在SCMV侵染早期表达量上调,后期下调表达。酵母双杂交(yeast two hybrid,Y2H)和双分子荧光互补(bimolecular fluorescence complementation,BiFC)试验表明,ScCRT1与SCMV-6K2蛋白互作。推测SCMV-6K2通过与ScCRT1互作调控钙离子稳态进而便于SCMV侵染。 | 张海 程光远 杨宗桃 王彤 刘淑娴 商贺阳 赵贺 徐景升 | 2021 | 作物学报2021，47，1： | 2 |
| 8 | Sugarcane mosaic virus infection of model plants Brachypodium distachyon and Nicotiana benthamiana显示文摘Sugarcane mosaic virus (SCMV;genus Potyvirus, family Potyviridae) is a causal pathogen of sugarcane mosaic disease, and it is widespread in regions where sugarcane (Saccharum spp. hybrids) is grown. It is difficult to investigate the molecular mechanism of pathogen infection in sugarcane because of limited genomic information. Here, we demonstrated that SCMV strain FZ1 can systemically infect Brachypodium distachyon inbred line Bd21 and Nicotiana benthamiana through inoculation, double antibody sandwich enzyme-linked immunosorbent, transmission electron microscopy, and reverse transcription PCR assays. The leaves of Bd21 developed mosaic symptoms, while the leaves of N. benthamiana showed no obvious symptoms under the challenge of SCMV-FZ1. We concluded that B. distachyon inbred line Bd21 is a promising experimental model plant compared with N. benthamiana for study on the infectivity of SCMV. This is the first report on the SCMV infection of model plants B. distachyon inbred line Bd21 and N. benthamiana, which will shed light on the mechanism of SCMV infection of sugarcane and benefit sugarcane breeding against sugarcane mosaic disease. | XU Jing-sheng DENG Yu-qing CHENG Guang-yuan ZHAI Yu-shan PENG Lei DONG Meng XU Qian YANG Yong-qing | 2019 | Journal of Integrative Agriculture2019，18，10： | 2 |
| 9 | Multiomic investigation of Sugarcane mosaic virus resistance in sugarcane显示文摘Sugarcane mosaic virus(SCMV)is the main etiological agent of sugarcane mosaic disease,which affects sugarcane and other grass crops.Despite the extensive characterization of quantitative trait loci controlling resistance to SCMV in maize,the genetic basis of this trait in sugarcane is largely unexplored.Here,a genome-wide association study was performed and machine learning coupled with feature selection was used for genomic prediction of resistance to SCMV in a diverse sugarcane panel.Nine single-nucleotide polymorphisms(SNPs)explained up to 29.9%of the observed phenotypic variance and a 73-SNP set predicted resistance with high accuracy,precision,recall,and F1 scores(the harmonic mean of precision and recall).Both marker sets were validated in additional sugarcane genotypes,in which the SNPs explained up to 23.6%of the phenotypic variation and predicted resistance with a maximum accuracy of 69.1%.Synteny analyses suggested that the gene responsible for the majority of SCMV resistance in maize is absent in sugarcane,explaining why this major resistance source has not been identified in this crop.Finally,using sugarcane RNA-Seq data,markers associated with resistance to SCMV were annotated,and a gene coexpression network was constructed to identify the predicted biological processes involved in resistance.This network allowed the identification of candidate resistance genes and confirmed the involvement of stress responses,photosynthesis,and the regulation of transcription and translation in resistance to SCMV.These results provide a practical marker-assisted breeding approach for sugarcane and identify target genes for future studies of SCMV resistance. | Ricardo JoséGonzaga Pimenta Alexandre Hild Aono Roberto Carlos Villavicencio Burbano Marcel Fernando da Silva Ivan Antônio dos Anjos Marcos Guimarães de Andrade Landell Marcos Cesar Gonçalves Luciana Rossini Pinto Anete Pereira de Souza | 2023 | The Crop Journal2023，11，6： | 0 |
