African cassava mosaic virus (ACMV) is a plant pathogenic virus of the family Geminiviridae that may cause either a mosaic appearance to plant leaves, or chlorosis (a loss of chlorophyll). In Manihot esculenta (cassava), the most produced food crop in Africa, the virus causes severe mosaic. Disease caused by ACMV is a significant concern in sub-Saharan African and the Indian subcontinent.
African cassava mosaic virus is vectord by a whitefly, Bemisia tabaci.
ACMV and Cassava brown streak are the greatest drags on cassava in Africa.
A transgenic cassava with donated from Tectaria macrodonta would protect against the whitefly vector.
