植物病毒侵染宿主植物的一个重要过程是通过它在宿主体内的转移和传播,产生病害。植物病毒在宿主体内的转移主要有两种方式,一种是通过植物维管组织进行的系统转移,另一种是植物病毒在宿主细胞之间的转移,这种转移是通过植物细胞的胞间连丝实现的。实验表明,病毒自身编码的一种蛋白参与了这个转移过程,对烟草花叶病毒(TMV)而言,这种蛋白就是分子量为30kDa的运动蛋白。 An important process by which a plant virus infects a host plant is through its transfer and spread in the host. There are mainly two ways for the plant virus to be transferred in the host. One is systemic transfer through plant vascular tissues and the other is the transfer of plant viruses between host cells through the intercellular Even the wire to achieve. Experiments show that the virus itself encodes a protein involved in this process of transfer, for tobacco mosaic virus (TMV), this protein is the molecular weight of 30kDa motor protein.
