Study on inhibitory effects of plant KELP proteins interacting with virus movement proteins on virus infection

为了培育抗病毒植物，有必要在分子水平上阐明植物固有的抗性基因是如何发挥作用的。在这项研究中，我们进行了KELP基因的功能分析，这已被证明是限制病毒感染传播。我们的研究结果表明，KELP，在广泛的植物物种中保守，与至少两种不同病毒的病毒因子（运动蛋白）相互作用，干扰其先天功能，从而限制病毒传播。

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.
