Cacao yellow mosaic virus (CYMV) is a virus in the family Tymoviridae that infects cacao trees in Sierra Leone.
Description
CYMV, like other Tymoviridae are non-enveloped viruses, surrounded by a capsid approximately 30 nanometers wide.[1] The viral capsid has T = 3 symmetry.[1] Tymoviridae have positive-sense single-stranded RNA genomes approximately 6 kilobases long.[1]
Disease
In the cacao tree, CYMV infection leads to the appearance of large circular yellow blotches on the leaves. Infected trees are not killed or severely inhibited.[2]
Ecology and distribution
CYMV has only been found in Sierra Leone where it primarily infects the cacao tree Theobroma cacao. However, it can experimentally infect a number of other dicots including Chenopodium amaranticolor, Chenopodium quinoa, Tetragonia expansa, Vinca rosea, Nicotiana clevelandii, and Nicandra physalodes.[2]
