Abstract


KIM, Woon Soo & In Yong SO (Dept. of Biology, Sungkyunkwan Univ.) Studies with two plant viruses on the mechanism of synthesis, Kor. Jour. Bot. V(3):30-36 1962
The mechanism of synthesis of the toacco mosaic virus (TMV) and the potato virus X (PVX) was investigated using the methods of ultraviolet light irradiation and serological analysis.
In vitro irradiation of UV on the infected tobacco juice for 10 minutes caused the infectivity of TMV and PVX to decrease markedly on their respective local lesion indicator hosts, Nicotiana glutionsa L., and Gomphrena globasa L. indicating that UV destroys direct]y the infectivity of the virus particles.
Ten minutes after the UV was irradiated on the leaves of the two indicater hosts before inoculation, the infectivity of TMV decreased as it was irradiated in vitro, whereas that of PVX increased by 26% as compared with the unirradiated control.
When the two viruses were mix-inoculated in the common host of tobacco and the synthetic products were analyzed by serological methods for a two week infection period, it was found that both viruses were multiplying more rapidly and abundantly than they were singly inoculated into the same host species. Titers from mixed series were often two times as high as those of singly inoculated series. A mechanism of competition in the synthesis between the mixed viruses in the common host is postulated.
