Cassava mosaic virus

英语百科

Cassava mosaic virus

The inflorescence of cassava (Manihot esculenta, Family Euphorbiaceae), a tropical tuber crop. Muruwere, Manica Province of Mozambique. The leaves show symptoms of cassava mosaic disease, caused by a virus.

African cassava mosaic virus (ACMV), East African cassava mosaic virus (EACMV), and South African cassava mosaic virus (SACMV) are distinct species of circular single-stranded DNA viruses that are whitefly-transmitted and primarily infect cassava plants. These have thus far only been reported from Africa; related species of viruses (Indian cassava mosaic virus, ICMV) are found in India and neighbouring islands (Sri Lankan cassava mosaic virus, SLCMV), though cassava is cultivated in Latin America as well as South East Asia. Nine species of cassava-infecting geminiviruses have been identified between Africa and India based on genomic sequencing and phylogenetic analysis. This number will probably grow due to a high rate of natural transformation associated with CMV.
