Limited Genetic Diversity

Worldwide, Cucumber mosaic virus (CMV) is the causal agent of many economically important diseases. Based on immunological or molecular analysis, three distinct subgroups of CMV isolates can be identified (IA, IB, and II). In addition, some CMV isolates are associated with satellite RNAs (satRNAs), a type of noncoding transcript that may alter the symptoms of CMV infections. This study presents an analysis of CMV isolates occurring in legumes in Greece in respect to their genetic diversity, and the presence and diversity of their satRNA. Phylogenetic analysis of the CMV coat protein sequence of 18 legume and 5 tomato CMV isolates collected throughout Greece classified them within subgroups IA and IB, with a limited genetic diversity. The CMV satRNAs found in nine field legumes exhibiting mild symptoms and in one tomato with a necrotic syndrome contained a functional necrogenic motif; therefore, they were grouped within the necrogenic group of CMV-satRNAs. The necrotic phenotype was expressed in all legume CMV isolates containing necrogenic satRNAs when mechanically inoculated onto tomato plants. To our knowledge, this is the first observation that legumes host necrogenic CMV-satRNAs. The possible role of legumes in the epidemiology of CMV and necrogenic satRNA complex is discussed.
