| Research Abstract |
In order to develop resistance plants for virus attacks, it is necessary to elucidate at molecular levels how inherent plant resistance genes act. In this study, we performed functional analyses of KELP genes, which had been shown to restrict virus infection spread. Our results have suggest that KELPs, conserved in a wide range of plant species, interact with a viral factor (movement protein) from at least two different viruses, interfere with their innate function, and consequently restrict virus spread.
