  • 본 논문에서는 종자전염 식물병원세균을 규정하였다. 국내 금지병해충 목록에서 세균 4종 및 파이토플라즈마 2종, 그리고 관리병해충 목록 중 세균 35종 및 파이토플라즈마 17종을 대상으로 종자내부 또는 유묘에서 병원세균을 검출한 문헌조사를 실시하였다. 금지 식물병원세균 2종, 관리 식물병원세균 18종 및 관리 파이토플라즈마 1종이 종자전염 식물병원세균으로 판명되었다. 이에 이들 종자전염 식물병원세균들에 대한 근거를 제시하였으며, 향후 수입종자의 검역을 위한 기본자료로 활용될 수 있을 것으로 생각된다.

  • The occurrence of potato(Sotanum tuberosum) viral diseases caused by Potato virus X(PVX), Potato virus Y (PVY), Potato leafroll virus(PLRV), Potato vims S(PVS), Potato virus M(PVM), Potato virus A(PVA), Potato virus T(PVT), Alfalfa mosic virus(AIMV), Tobacco mosic virus(TMV), Potato mop top virus(PMTV) Tobacco rattle virus(TRV) and Potato spindle tuber viroid(PSTVd), potato witches' broom phytoplasma, have been identified so far in Korea. Major viral diseases such as PVX, PVY and PLRV had been studied more deeply, however, the others are just identified and only partially characterized since the first study on the relation between PVX nucleic acid and virus protein by Kim in 1961. The most studies on potato viral diseases are mainly focused on the problems of seed potato production. The National Alpine Agricultural Experiment Station(NAAES), since it began its activities in 1961, has given special attention to this problem by doing studies to identify, characterize and control potato virus diseases. This effort resulted in the development of new potato virus detection methods as a basis for elaborating new method of control, such as the production of seed potato free of virus and the selection of new virus-resistant transgenic potatoes. The further studies of potato viral diseases required would be fallowings: the continuous monitoring for the occurrence of identified or not identified potato viruses in Korea, the isolation of resistant viral genes, the development of control method for the non-persistently transmitted viruses like PVY, special vectors such as nematode and fungus transmitted viruses, TRV and PMTV and the development of control methods against potato viral diseases by viral cross protection, therapy, transgenic plant, and the use of the agents or molecules, such as virus inhibitors and antiviral proteins, etc., blocking viral replication.
