: Inspection of the nucleotide sequences of the RNAs complementary to the coat protein mRNAs from two plant viruses with a tripartite genome: alfalfa mosaic virus and brome mosaic virus, showed the presence of open reading frames for 138 and 118 amino acids, respectively. A third virus (cowpea chlorotic mottle virus) from the same family (1) does not show this phenomenon. This suggests that if a protein is coded for by the open reading frames it may be not essential for virus multiplication. Alternatively the open reading frames have no coding function but result from structural requirements of the RNAs.
对具有三分体基因组的两种植物病毒（苜蓿花叶病毒和雀麦花叶病毒）的外壳蛋白 mRNA 的互补 RNA 的核苷酸序列进行检测，发现分别有 138 个和 118 个氨基酸的可读框。同一家族的第三种病毒（豇豆花叶病毒）（1）没有表现出这种现象。这表明，如果可读框编码一种蛋白质，它可能不是病毒增殖所必需的。或者，可读框没有编码功能，而是 RNA 结构要求的结果。
