Cacao yellow mosaic virus (CYMV) is a virus in the family Tymoviridae that infects cacao trees in Sierra Leone.
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]
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]
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 .
