  • A Korean isolate of Pepper mild mottle virus (PMMoV-Kr) was isolated from a diseased hot pepper plant and its biological and molecular properties were compared to that of PMMoV-J and PMMo V -So The genomic RNA of PMMoV-Kr consists of 6,356 nucleotides. The nucleotide and amino acid sequences identities of four viral proteins and two noncoding regions among PMMoV-Kr, PMMoV-S and PMMoV-J were $96.9\%\;to\;100.0\%\;and\;97.5\%\;to\;98.6\%$, respectively. Full-length cDNA amplicon of PMMoV-Kr was directly amplified by RT-PCR with a set of 5'-end primer anchoring T7 RNA promoter sequence and 3'-end virus-specific primer. Capped transcript RNAs from the full-length cDNA clone were highly infectious and caused characteristic symptoms of wild type PMMoV when mechanically inoculated to systemic host plants such as Nicotiana benthamiana and pepper plants.

  • The commercial cultivars of red pepper were screened against Tobacco mosaic virus (TMV), Pepper mild mottle virus (PMMoV) and Pepper mottle virus (PepMoV) by seedling test. Tn single infection of TMV or PMMoV, mosaic symptom was produced on the cultivars of 'Cheongyang'and 'Wangshilgun'. However, in cultivars of 'Manilla'and 'Bugang', symptoms were not occurred. In single infection of PepMoV, symptoms of mottle and malformation were produced on the tested cultivars of 'Manilla', 'Bugang', 'Cheongyang'and 'Wangshilgun' In the cultivars of 'Cheongyang'and 'Wangshilgun', synergistic symptoms of stunt and lethal death were induced by mixed infections in the two combinations of TMV+PepMoV and PMMoV+PepMoV. However, in cultivars of 'Manilla'and 'Bugang', synergistic symptom was not occurred as mottle which was milder than that of single infection. Cells were single infected with TMV and PMMoV the cultivars of 'Cheongyang'and 'Wangshilgun', respectively, had typical ultrastructures of tobamovirus as the stacked-band structure and multiple spiral aggregate (SA). Ultrastructures of cell and tissues infected with PepMoV on the cultivars of 'Cheongyang', 'Wangshilgun', 'Manilla'and 'Bugang', the potyvirus inclusions of pinwhills, scrolls, lamminated aggregates and amorphous inclusion were observed. Infected cells with a combination of TMV+PepMoV and PMMoV+PepMoV, the virus particles and inclusions of the two different viruses were found only mixed infection in the same cytoplasm and the amounts of viruses in mixed infections were abundant than in single infection. The angled-layer aggregates (ALA) was observed in the cells infected mixedly with TMV and PepMoV

  • A Korean isolate of Pepper mild mottle virus (PMMoV-Kr) was isolated from a diseased pepper crop in Chunchon, Korea. The isolate was biologically purified on Nicoticaa tabacum cv. Xanthi-nc by successive single local transfer steps, and propagated on N. tabacum cv. Samsun. PMMoV-Kr could systemically infect on N. glauca, N. benthmiana, N. occidentalis and Lycopersicon esculentum, which is typical of known isolates of PMMoV. PMMoV-Kr belongs to the pathotype P1,2 based on pepper-tobamoviral indicator experiments; Capsicn chinone harboring L3 gene revealed resistant (necrotic local lesion on inoculated leaf, HR) whereas L+, L1 and L2 pepper plants expressed susceptible reactions of mosaic systemic symptoms for the isolate. To confirm the pathology and delineate symptom determinant of the isolate, full-length cDNAs of PMMoV-Kr were amplified by RT-PCR with a primer set corresponding to the 5'- and 3'-ends of PMMoV. The RT-PCR molecules amplified from genome RNA of the isolate was cloned into the pUC18 vector. Full-length cDNA clones constructed under the control of the T7 RNA promoter could be successfully transcribed to produce in vitro transcript RNA. Infectivity of the capped transcripts and its progeny virus was verified by Western blot and RT-PCR analyses.

  • In single infection of Tobacco mosaic virus-U1 (TMV­U1) or Pepper mild mottle virus (PMMoV), mosaic symptoms were produced on the chili pepper cultivars of 'Cheongyang' and 'Wangshilgun'. However, in cultivars of 'Manitta' and 'Bugang', no symptoms were occurred. In single infection of Pepper mottle virus (PepMoV), symptoms of mottle and malformation were produced on the tested cultivars of 'Manitta', 'Bugang', 'Cheongyang', and 'Wangshilgun'. In the cultivars of 'Cheongyang' and 'Wangshilgun', synergistic symptoms of stunt and lethal death were induced by mixed infections in the two combinations of TMV-U1 + PepMoV and PMMoV+PepMoV. However, in cultivars of 'Manitta' and 'Bugang', synergistic symptoms were not noted, but mottling which was milder than that of single infection was produced. Cells infected singly with TMV-U1 and PMMoV in the cultivars of 'Cheongyang' and 'Wangshilgun', respectively, had the typical ultra-structures of tobamovirus as the stacked-band structure and multiple spiral aggregate (SA). In the cells and tissues infected with PepMoV on the cultivars of 'Cheongyang', 'Wangshilgun', 'Manitta' and 'Bugang', the potyvirus inclusions of pinwheels, scrolls, lamminated aggregates and amorphous inclusion were observed. In the cells infected mixedly with combinations of TMV­U1+PepMoV and PMMoV+PepMoV, the virus particles and inclusions of the two different viruses were found simultaneously in the same cytoplasm. The amounts of virus particles in mixed infections were more abundant than in single infection. The angled-layer aggregates (ALA) were observed only in the cells infected with both TMV-U1 and PepMoV.

  • We conducted a survey on pepper virus diseases in 31 regions in Korea from November 2001 to December 2004. Using electron microscopy, test plant reaction, rapid immuno-filter paper assay (RIPA), reverse transcription-polymerase chain reaction (RT-PCR) and/or analysis of viral nucleotide sequences, we found a number of viruses from 1,056 samples that we collected. These included Cucumber mosaic virus (CMV), Pepper mottle virus (PepMoV), Pepper mild mottle virus (PMMoV), Broad bean wilt virus 2 (BBWV2), Tobacco mild green mosaic virus (TMGMV), and Tomato spotted wilt virus (TSWV). Of the samples analyzed, $343(32.5\%)$ were infected with CMV, $209(19.8\%)$ with PepMoV, $141(13.4\%)$ with PMMoV, $12(1.1\%)$ with BBWV2, $40(3.8\%)$ with TMGMV, $5(0.5\%)$ with TSWV, $153(14.5\%)$ with CMV and PepMoV, $54 (5.1\%)$ with CMV and PMMoV, $31(2.9\%)$ with PepMoV and PMMoV, $3(0.3\%)$ with CMV and BBWV2, $1(0.1\%)$ with CMV, PepMoV and BBWV2, $8(0.8\%)$ with CMV, PepMoV and PMMoV, and $30 (2.8\%)$ samples were infected with viruses which were not identified. CMV was the most predominant virus in all inspected fields and the number of the samples infected with PMMoV was relatively low as compared PepMoV infection level in pepper. TMGMV was only found in the southern part of Korea, while TSWV was isolated in Anyang and Yesan. However, we did not encounter in this survey the Alfalfa mosaic virus (AMV), Potato virus Y (PVY), Tobacco mosaic virus (TMV), and Pepper vein chlorosis virus (PVCV).

  • The pepper mild mottle virus (PMMoV), belonging to the tobamovirus genus, is currently one of the most destructive pathogens in pepper production. Tobamoviruses have been classified in terms of increased pathogenicity as pathotypes P0, P1, P1,2, P1,2,3 and P1,2,3,4, based on their ability to infect systemically Capsicum L0 , L1 , L2 , L3 and L4 resistant plants, respectively. Two hundred eighty pepper germplasms and 5 reference accessions known as resistant L alleles, were analyzed to select the resistance cultivars against PMMoV- P1,2,3 (CV130614-2) using bioassay and genetic markers. The susceptible accessions showed systemic symptom when inoculated with PMMoV- P1,2,3. However, accessions including IT223737, were resistant as they developed necrotic local lesions only on inoculated leaves, whereas no symptoms were observed on the upper leaves. Moreover, RT-PCR results for detecting the presence of virus were also negative. Thus, those accessions will be used as a novel source to facilitate introduction the resistant gene into commercial cultivars of pepper.

  • 닭을 이용한 egg yolk immunoglobulin (IgY)의 생산과 이용 가능성을 조사하기 위하여 pepper mild mottle virus (PMMoV)로 닭을 면역하였다. Ring-test로 달걀의 난황에서 분리 정제한 IgY의 역가를 조사한 결과 IgY의 최고 역가는 1:2,560이었고 달걀 l 개에서 대략 $60{\sim}80 mg$의 IgY를 얻을 수 있었다. 최고역가를 갖는 IgY를 이용하여 Gelrite gel 이중확산법, 효소면역항체법 (ELISA), 조직자국면역반응법을 실시한 결과 간접면역효소항체법의 PMMoV 검출 감도는 1 ng/ml 이었고, 검정법의 바이러스 검출감도와 특이도는 IgG와 비슷한 경향을 보였다. 그러므로 한 마리의 닭으로부터 대량으로 생산 가능한 IgY는 식물바이러스에 대한 항체생산과 혈청학적 검정에 유용할 것으로 생각한다.
