The conditions determining conformational changes in the four ribonucleic acid components of cowpea chlorotic mottle virus have been studied. All four components have at least two electrophoretically separable conformers, the occurrence of which can be regulated by both monovalent and polyvalent cations. This phenomenon also occurs, in a much less striking way, in the ribonucleic acids of the two other members of the bromovirus group, brome mosaic virus and broad bean mottle virus. Although specific in some respects, these changes have much in common with effects which have been observed in tRNAs, 55 RNAs and rRNAs. A provisional interpretation of the conformational behaviour of the viral RNAs is given in terms which have been proposed for certain tRNAs which have been studied in great detail.
对豇豆褪绿斑驳病毒四种核糖核酸成分构象变化的决定条件进行了研究。所有四种成分至少有两种可通过电泳分离的构象异构体，其出现可由单价和多价阳离子调节。这种现象在雀麦花叶病毒组的另外两个成员，即雀麦花叶病毒和蚕豆斑驳病毒的核糖核酸中也有发生，但程度要小得多。尽管在某些方面具有特异性，但这些变化与在转运核糖核酸、55核糖核酸和核糖体核糖核酸中观察到的效应有许多共同之处。根据对某些已进行详细研究的转运核糖核酸所提出的术语，对病毒核糖核酸的构象行为进行了初步解释。
