| 1 | Wheat streak mosaic virus: incidence in field crops, potential reservoir within grass species and uptake in winter wheat cultivars显示文摘Wheat streak mosaic virus(WSMV)has become a re-emerging pathogen in cereal crops in the Czech Republic.WSMV was first reported in the former Czechoslovakia in the early 1980s,and then no record of the virus was documented until 2009.The incidence of the virus was recorded in recent years in several winter wheat fields and many grass species.Here,we surveyed the incidence of WSMV in cereal crops.The results demonstrated the existence of the virus in winter wheat and volunteer wheat during each year of the monitoring period,which spanned from 2013–2016.Although the range of infected samples was low(6.4%of the total tested samples),a high incidence of well-distributed virus was recorded.In at least six fields,the virus reached severe and potentially epidemic levels.In accordance with our previous report detailing WSMV infection of native grasses,we tested several grass species commonly grown in the Czech Republic.We found that some grass species acted as experimental hosts and possible reservoirs of the virus;these included Anthoxanthum odoratum(sweet vernal grass),Arrhenatherum elatius(false oat-grass),Lolium multiflorum(Italian rye-grass),Bromus japonicus(Japanese chess),Echinochloa crus-galli(barnyard grass),Holcus lanatus(meadow soft grass)and Holcus mollis(creeping soft grass).Some of these grass species are also important weeds of cereals,which may be the potential source of WSMV infection in cereal crops.Several widely used winter wheat cultivars were tested in the field after artificial inoculation with WSMV to evaluate virus titre by RT-qPCR.Overall,the tested cultivars had a low virus titre,which is associated with mild disease symptoms and may provide a good level of crop resistance to WSMV. | Jana Chalupniková Jiban Kumar Kundu Khushwant Singh Pavla Bartaková Eva Beoni | 2017 | Journal of Integrative Agriculture2017，16，3： | 4 |

| 4 | Molecular diversity of barley yellow dwarf virus-PAV from China and the Czech Republic显示文摘Wheat yellow dwarf disease(BYD),caused by different species of barley/cereal yellow dwarf viruses(B/CYDVs),is one of the most serious cereal diseases in China and the Czech Republic.Because genetic diversity of the virus directly influences disease epidemiology,the molecular diversity and population structure of 24 Chinese isolates and 16 the Czech Republic isolates of BYDV-PAV from different regions in two countries were analyzed by sequencing their coat protein(CP)and readthrough protein(RTP)domain(RTD)genes and comparing the sequences with six CP and 16 RTP sequences of BYDVPAV isolates from the NCBI database based on nucleotide identity position,phylogenetic analysis and nucleotide diversity.Nucleotide identities between the Chinese and the Czech Republic isolates for the CP were 76.6–99.4%,73.9–89.1%for RTD(ORF5),respectively.The Chinese and the other country isolates showed 74.7–99.2%nucleotide identity for RTP(ORF3+ORF5).Phylogenetic analysis of CP sequences showed that 20 Chinese isolates clustered in the same clade,but the other four Chinese isolates clustered in another clade with the isolates from the Czech Republic and other counties.The population of BYDV-PAV in China had greater nucleotide variability and was more divergent than that in the Czech Republic.Geographical and ecological factors but not hosts might contribute to the population differences in the two countries. | May Oo KHINE Brozenka MICHAELA LIU Yan Jiban Kumar KUNDU WANG Xi-feng | 2020 | Journal of Integrative Agriculture2020，19，11： | 1 |

| 9 | Transgenic plum Prunus domestica L., clone C5(cv. Honey Sweet) for protection against sharka disease显示文摘Sharka caused by Plum pox virus(PPV)is the most harmful disease of stone fruits in Europe and elsewhere in the world.There is no highly PPV resistant cultivar of plum.Biotech approach has led to the development of resistance through genetic engineering.In this study,we evaluated a transgenic plum Prunus domestica L.,clone C5(cv.Honey Sweet),where the PPV resistance is based on RNA interference(RNAi).Resistance in C5 plums has been evaluated for PPV,Prune dwarf virus(PDV),and Apple chlorotic leaf spot virus(ACLSV)in a regulated field trial in the Czech Republic for 12 years(2002–2013).Even under high and permanent infection pressure introduced through graft inoculation of the viruses,PPV has been detected in C5 trees only in several leaves situated close to the point of inoculum grafting in the first nine years.Mild symptoms of PPV disappeared year by year.No PPV symptoms were observed in the last three years and results of ELISA detection were negative.Similar results were obtained,when RT-PCR was used for PPV detection.No natural infection of PPV by aphids was recorded in C5 plums,even if PPV infected plants were growing in the same experimental field in close vicinity.Co-infections of PPV with PDV and/or ACLSV had practically no influence on stability of resistance in C5 trees.Twelve years of field testing in the Czech Republic clearly demonstrated the high level of resistance of C5 either to PPV infection by graft inoculation or natural infection through aphid vectors. | Jaroslav Polák Jiban K Kundu Boris Krska Eva Beoni Petr Komínek Jitka Pívalová Jana Jarosová | 2017 | Journal of Integrative Agriculture2017，16，3： | 1 |

| 15 | Virome identification in wheat in the Czech Republic using small RNA deep sequencing显示文摘High-throughput deep-sequencing technology and bioinformatics analysis of the small RNA(sRNA)population isolated from plants allows universal virus detection and complete virome reconstruction for a given sample.In the present sRNA deep-sequencing analysis of virus-infected wheat samples in the Czech Republic,samples were firstly tested for barley yellow dwarf viruses(BYDVs),wheat streak mosaic virus(WSMV)and wheat dwarf virus(WDV)using ELISA,RT-PCR and PCR.Subsequent sRNA sequencing of these samples yielded more than^60 million single-end 50-bp reads with high confidence for nine field samples of wheat.Overall,16.5%of reads were virus-specific and 83.5%were mapped to the host.More 21-nt reads(-7.7E+06 reads)were found than 24-nt(~6.20E+06 reads)or 22-nt(-4.30E+06 reads)reads.De novo assembly of the high-quality contigs revealed the presence of three earlier repoted viruses in the Czech Republic:BYDVs(31.48%),WSMV(24.23%)and WDV(2666%).We also showed the presence of cereal yellow dwarf virus(14.33%;two species CYDV-RPS and CYDV-RPV family Luteoviridae/Polerovirus)and wheat yellow dwarf virus(WYDV,3.30%;Luteoviridae).Phylogenetic analysis showed CYDV and WYDV grouped separately from BYDVs.Furthermore,several recombination breakpoints were found among the groups of yellow dwarf viruses(BYDVs,CYDV,and WYDV).Using RNA deep sequencing,we confirmed the presence of the three known viruses(BYDVs,WSMV,and WDV)and the first record of two species of CYDV and WYDV in wheat in the Czech Republic. | Khushwant SINGH Jana JAROSOVA Jan FOUSEK CHEN Huan Jiban Kumar KUNDU | 2020 | Journal of Integrative Agriculture2020，19，7： | 1 |
| 16 | Viral pathogens and plant parasitic nematode显示文摘This special focus is dedicated to three parts:i)One of the most ubiquitous viral pathogens of stone fruit tree,Plum pox virus(PPV);ii)a re-emerging pathogen,Wheat streak mosaic virus(WSMV)of cereal crops in Central Europe;and iii)a less studied plant parasitic,cyst-forming nematode in cereal crops Heterodera avenae.The pathogens described here are a serious concern for fruit growers | Jiban Kumar Kundu | 2017 | Journal of Integrative Agriculture2017，16，3： | 0 |
| 17 | Quantitative analysis of the interaction of heterologous viruses with Plum pox virus in C5 HoneySweet transgenic plums显示文摘Stone fruits are an important crop in most parts of the world and are heavily challenged by several viruses including Plum pox virus (PPV), Prune dwarf virus (PDV), Prunus necrotic ringspot virus (PNRSV), and Apple chlorotic leaf spot virus (ACLSV). We validated the PPV resistance in C5 plum plants (commercially known as HoneySweet) grown in the Czech Republic for more than 16 years in a field trial experiment under natural environmental conditions. We quantified single (PPV-Rec) and mixed viruses (PPV-Rec+ACLSV, PPV-Rec+PDV and PPV-Rec+ACLSV+PDV) in C5 transgenic plums inoculated for the period 2016 to 2018. The accumulation of PPV-Rec was high (~5.43E+05 copies) compared with that of ACLSV (~8.70E+04 copies) in the inoculated graft of C5 transgenic plants. Leaves close to the inoculum sources showed a differential level of virus titre in single and mixed infections (~10 to ~5×10^2 copies). C5 plants with permanent virus pressure showed 103- to 105-fold fewer copies of viruses than those of the inoculated graft. We observed high accumulation of conserved miRNAs such as miR167, miR69 and miR396 in C5 plants co-infected with PPV, ACLSV and PDV that are associated with its resistance against viruses. Overall, i) C5 transgenic plums showed high resistance to PPV infection, and a low level (~32 copies) of PPV only accumulated in some grafted plants, ii) high accumulation of PPV was found in inoculated grafts in single PPV infection and mixed infections, iii) heterologous virus infection sustained by ACLSV or PDV did not suppress PPV resistance, and iv) high and low conserved microRNAs accumulated in C5 plants. | Khushwant Singh Tereza Neubauerová Jiban Kumar Kundu | 2019 | Journal of Integrative Agriculture2019，18，10： | 0 |
| 18 | Texture coefficient and band gap tailoring of Fe-doped SnO_(2) nanoparticles via thermal spray pyrolysis显示文摘An investigation of Fe-doping effect on SnO_(2) thin films was performed in this study using thermal spray pyrolysis(TSP) method.The surface morphology and structural,optical and electrical properties were studied by field energy scanning electron microscope(FESEM),X-ray diffraction(XRD),ultraviolet-visible(UV-Vis) spectroscopy and four-point probe method.FES EM images demonstrate that the surface morphology of the as-deposited films varies when Fe-doping content varies.XRD studies reveal that crystallite size and preferential growth orientations of the films are dependent on Fe-doping concentrations.The grain size is found to decrease with the increase in Fe content.These studies also specify that the films have tetragonal rutile-type structure with mixed secondary phases.The texture coefficient value of(110) plane increases with the concomitant in-plane(220) decrease in higher doping concentrations.The resistivity and the optical absorbance are found to increase with Fe concentration.The direct optical band gap decreases from 3.94 to3.52 eV with increasing Fe content. | Majibul Haque Babu Bidhan Chandra Dev Jiban Podder | 2022 | Rare Metals2022，41，4： | 0 |
| 19 | Two mutations in the truncated Rep gene RBR domain delayed the Wheat dwarf virus infection in transgenic barley plants显示文摘Wheat dwarf virus(WDV), an important cereal pathogen, is closely related to maize streak virus(MSV), a model virus of the mastrevirus genus. Based on its similarity to known MSV resistance strategies, a truncated part of the WDV replicationassociated(RepA) gene(WDVRepA215) and the WDV RepA gene with a mutated retinoblastoma-related protein(RBR) interaction domain(WDVRepA215 RBR^(mut)) were cloned into the pIPKb002 expression vector and transformed into immature embryos of spring barley cv. Golden Promise plants through Agrobacterium-mediated transformation. A detailed study of T1-generation plants infected by leafhoppers(Psammotettix alienus) fed on infection sources of variable strength was performed over a 5-week period encompassing the initial stages of virus infection. A DNA WDV TaqMan qPCR assay normalized using the DNA puroindoline-b SYBR Green qPCR assay for samples on a per week basis revealed an approximately 2-week delay in WDVRepA215 RBR^(mut) plants to WDVRepA215 plants before significant increases in the WDV viral levels occurred. Both WDVRepA215 and WDVRepA215 RBR^(mut) plants showed similar levels of transgenic transcripts over the screened period; however, the transgenic plants also showed increased numbers of infected plants compared to the control plants. | Pavel Cejnar Ludmila Ohnoutkova Jan Ripl Tomas Vlcko Jiban Kumar Kundu | 2018 | Journal of Integrative Agriculture2018，17，11： | 0 |
