팥 바이러스병에 대한 기초자료를 얻고자 병징의 유형과 생육 단계별 감량정도 및 수량에 미치는 영향을 조사하고 병징 유형별 바이러스를 분리 동정한 결과는 다음과 같다. 1. 팥에 발생되는 바이러스병의 병징은 크게 mosaic, yellow mosaic 및 severe mosaic의 3가지 군으로 분류되었으며 병징별 분포는 mosaic＞severe mosaic＞yellow mosaic 순이었다. 2. 성숙기까지 매개충 차단 재배시의 이병률은 1.5%(방임구 20.7%)로서 생육 후기에 감량될수록 이병률이 낮았으며 10a당 수량도 171kg으로서 방임구에 비하여 45% 증수되었다. 3. 지표식물 검정 결과 mosaic 유형은 CMV, yellow mosaic 유형은 AMV, severe mosaic 유형은 AzMV의 기주범위와 유사하였다. 4. 항혈청에 의한 각 병징별 반응결과 yellow mosaic 유형의 시요는 AMV 항 혈청과 mosaic 유형의 시요는 CMV의 항혈청과 침강선이 형성되어 각각 AMV 및 CMV의 한 계통으로 판정되었다. 5. 병징 유형별 전자현미경 관찰결과 yellow mosaic유형은 18~58$\times$18nm의 타원형 입자가 다수 관찰되었고 mosaic 증상의 시요에서는 직경 30nm의 구형 입자, severe mosaic병징의 시요에서는 730$\times$12nm의 사상형 입자와 봉입자가 관찰되었다.

Gentian plants (Gentiana spp.) showing yellow ringspot, mosaic, necrotic fleck and malformation were collected from their growing areas in Taegu, Kyungpook province and Alpine Agricultural Experiment Station, Korea. Three viruses isolated from the naturally infected gentian were identified as broad bean wilt virus (BBWV), cucumber mosaic virus (CMV) and clover yellow vein virus identified as broad bean wilt virus (CIYVV) by their host range, immunosorbent electron microscopy (ISEM) and electron microscopy. Electron microscopic examination of negatively stained preparations showed that BBWV and CMV are spherical particles of 28 nm and 30 nm in diameter, and CIYVV is filamentous particles of ca. 780 nm in length. By ISEM, BBWV was detected mainly in gentian showing yellow ringspot and mottle, CIYVV in necrotic fleck leaf of gentian and CMV in narrow and distorted mosaic leaf of gentian. BBWV and CMV are the most prevalent in the cultivated gentian. In ultrathin sections of BBWV infected tissues, large aggregates of crystalline array of virus particles and vesicular body were found in the cytoplasm and vacuole of mesophyll cells. In case of CIYVV, pinwheel- and laminated aggregate-type inclusions as well as filamentous virus particles were observed in the cytoplasm of mesophyll cells.

A virus causing chlorotic ringspot, yellow mosaic and vein clearing symptoms was prevalent on mungbean plants around Taean, Korea. The isolate caused mosaic on Chenopodium quinoa, Nicotiana benthamiana, Phaseolus vulgaris and Vida laba but no symptoms on peanut plants. Inclusion bodies such as scroll, pinwheel and laminated aggregates induced by the virus in the host cells were similar to those produced by members of the Potyvirus subdivision III. Multiple alignment as well as cluster dendrograms of the 709 nucleotide region comprising part of the coat protein gene and 3'untranslated region (UTR) showed that the isolate belongs to the BCMV-PSt subgroup. Altogether, these results support the identification of the causal virus as peanut stripe strain of Bean common mosaic virus (BCMV-PSt).

Gladioli (Gladiolus hybridus) showing flower colour breaking, leaf mosaics, necrotic fleck, and dwarfing or lack of visible symptoms were collected from gladioli growing areas in Taegu and Kyungpook province, Korea. The two viruses isolated from the naturally infected gladioli were identified as ban yellow mosaic virus (BYMV) and clover yellow vein virus (CIYVV) by their host range, immunosorbent electron microscopy (ISEM), enzyme-linked immunosorbent assay (ELISA), direct tissue blotting immunoassay (DTBIA) and intracellural symptoms. In ultrathin sections of BYMV and CIYVV infected tissues, laminated aggregate-type inclusions, cytopalsmic bodies and nuclear inclusions as well as filamentous virus particles were observed in the cytoplasm of parenchyma cells. By DTBIA and ISEM, BYMV was detected in all tested gladiolus plants showing severe or mild mosaic symptoms, whereas CIYVV were mainly detected from those of mild mosaic symptoms. BYMV is the most prevalent in commercial gladioli and present major production problems. Detection sensitivity of BYMV and CIYVV in crude sap of infected gladiolus leaves by ISEM was about twice compared with ELISA. In a comparison of ELISA, ISEM, DTBIA, BYMV was detected in same degree by DTBIA in samples where sap extracts were positive in both ELISA and ISEM. DTBIA provides a specific, rapid, and simple tool for large-scale diagnosis of BYMV.

Bean yellow mosaic virus (BYMV; genus Potyvirus, family Potyviridae) causes severe losses to various legume species and a number of non-legume species, particularly freesia plants. In a survey of virus diseases in Gyeonggi province, Korea, BYMV isolates were identified from many cultivated freesia species. Here, we determined the complete nucleotide sequences of a BYMV freesia isolate (BYMV-Fr; accession number FJ492961). BYMV-Fr genome consists of 9,545 nucleotides (nt) excluding the poly (A) tail and encodes 3,057 amino acid (aa), with an AUG start and UAG stop codon, containing one open reading frame typical of a potyvirus polyprotein. The polyprotein of BYMV-Fr was divided to ten proteins and the cleavage sites of each protein were determined. The coat protein (CP) and polyprotein of BYMV-Fr were compared at the aa level with those of the previously reported 4 BYMV isolates. BYMV-Fr shared 90.1 to 97.1 and 91.0 to 92.5% at the CP and polyprotein homology. Interestingly, BYMV-Fr showed identities of a lower level at the nt level of 5' noncoding region (61.4 to 67.6%) and at the aa level of P1 (71.4 to 72.8%), comparing with four BYMV isolates. Based on the aa sequence diversity of CP and polyprotein, phylogenetic analysis with the four BYMV isolates showed two distinct groups and BYMV-Fr and most BYMV isolates were most closely related to the clover yellow vein virus among 52 potyviruses. To our knowledge, this is the first report of the complete genome sequence of BYMV freesia strain.

The coat protein gene of iris severe mosaic potyvirus, which was isolated in Korea, ISMV-K, from iris plant was cloned and its nucleotide sequence was determined. The coat protein of the virus contained 252 amino acid residues, including five potential N-glyxosylation site motifs. The coat protein of ISMV-K has 99.1% and 98.4% sequence identities with those of the Netherlands isolate of ISMV (ISMV-Ne) form crocus for the nucleotide and amino acids, respectively. The coat protein of ISMV-K has 50.4% to 60.3% nucleotide sequence identities and 47.3% to 55.7% amino acid identities with those of other 21 potyviruses, indicating ISMV to be a distinct species of the genus. The coat protein of ISMV-K was closely related with bean yellow mosaic virus and clover yellow vein virus in the phylogenetic tree analysis among the potyviruses analyzed. ISMV was easily and reliably detected from virus-infected iris leaves by RT-PCR with a set of the virus-specific primers.

그라디오러스에 발생하는 바이러스병을 포장에서 조사한 결과 이 병율이 $43.3\%$이었다. BYMV는 명아주에 엽맥괴사병징, 강남콩에 심한 모자익 병징 그리고 잠두에 모자익 병길을 일으켰다. CMV는 명아주에 국부병반, 담배와 오이에 모자익 병징을 일으켰다. 분류 동정된 두 바이러스는 모두 복숭아 혹진딧물에 의하여 전염되었다. 바이러스를 순화하여 흡광도를 측정한 결과 두 바이러스 모두 260nm에서 최고의 흡광도를 나타내었다. 한천내확산법을 이용한 항혈청과의 반응 결과 SDS를 처리한 BYMY와 CMV는 각각 그 바이러스의 항혈청과 뚜렷한 반응대를 형성하였다. 바이러스 입자의 진자현미경검경 과파 BYMV는 길이가 750nm였으며, CMV는 직경이 30nm이었다.

A virus causing vein banding, sometimes yellow mosaic and rugose symptoms on peanut was prevalent around Suwon, Korea. A survey conducted in the area found disease incidence, depending on cultivar, to range from 79 to $100\%$. The virus was found to be seed-transmissible in all the five peanut cultivars tested with transmission rates ranging from 2 to $16\%$. Host range analysis failed to differentiate 9 field isolates collected from different peanuts cultivars showing various symptoms. Inclusion bodies such as scroll, pinwheel and long laminated aggregates induced by the virus in host plant cells were similar to those induced by members of the Potyvirus subdivision III. The virus showed < $95\%$ homology with Bean common mosaic virus (BCMV), BCMV-BICMV/AzMV strains and only < $91\%$ with Desmodium mosaic virus. Based on biological characterization, electron microscopy and molecular analyses of a Korean isolate (Daewon 1), the virus was identified as peanut stripe strain of BCMV.
