Cheraviruses, Sadwaviruses and Torradoviruses (Secoviridae)

Viruses that are classified to the genera Cheravirus, Sadwavirus and Torradovirus share many common properties with other viruses in the subfamily Comovirinae, in the family Secoviridae. Each genus is distinguished from the others by it’s specific genomic organization, biological properties and phylogenetic relationships. Main hosts include pome fruits and stone fruits for cheraviruses, citrus for sadwaviruses and tomato for torradoviruses, although other crops are seriously damaged by some viruses and their strains. Some cheraviruses and torradoviruses are transmitted by nematodes and whiteflies, respectively, while no vector is known for sadwaviruses, although soil transmission is suspected
