A coat-protein-free mutant of tobacco mosaic virus as well as mutants with a non-functional coat protein were found to interfere with the establishment and spread of challenging strains of TMV. The results do not support an earlier concept, according to which the genome of a related challenging virus could be captured by the coat protein of the virus introduced in advance. The presence of a viral coat protein is obviously not essential and a competition among the viral genomes for some specific site seems to be a more likely mechanism of cross protection.
烟草花叶病毒无衣壳蛋白突变体以及衣壳蛋白无功能的突变体被发现会干扰烟草花叶病毒挑战株的建立和传播。这些结果不支持早期的一个概念，即预先引入病毒的衣壳蛋白可以捕获相关挑战病毒的基因组。病毒衣壳蛋白的存在显然不是必需的，病毒基因组之间对某些特定位点的竞争似乎是一种更可能的交叉保护机制。
