African cassava mosaic virus (ACMV, ICTV approved acronym) 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.

Cassava is a staple food crop in many places throughout the tropics and subtropics as a source of carbohydrates, but the transmission and severity of disease for cassava in Africa is greatest with ACMV.

[clarification needed] African cassava mosaic virus is vectord by a whitefly, Bemisia tabaci.

[1] A transgenic cassava with Tma12 donated from Tectaria macrodonta would protect against the whitefly vector.
