Closteroviridae is a family of viruses. Plants serve as natural hosts. There are seven genera in this family. Diseases associated with this family include: yellowing and necrosis, particularly affecting the phloem.
Taxonomy

Genome type and transmission vector are two of the most important traits used for classification. Ampeloviruses and Closteroviruses have monopartite genomes and are transmitted by pseudococcid mealybugs (and soft scale insects) and aphids respectively. While Criniviruses are bipartite and transmitted by whiteflies.
