| Popis: | p lant viruses with single stranded plus-type RNA (ssRNA § genomes normally contain the information for only 3 to 10 proteins. Remarkably this limited information is often distributed over 2 (Bruening, 1977) or 3 (Van Vloten-Doting and Jaspars, 1977) RNA molecules. In the last 15 years the genome of viruses belonging to seven different groups (Table 1) was found to be multipartite. In contrast to most animal viruses with multipartite genomes, the genome parts of plant viruses are separately encapsidated into nucleoprotein particles. The requirement to infect a cell with more than one particle results in a less efficient mechanical transmission. This does not imply that in nature the transmission is also impaired. Plant viruses are often transmitted by seed or invertebrate vectors (Table 1) ensuring the introduction of rather large numbers of virus particles into one cell. |
