Abstract Cassava is infected by numerous geminiviruses in Africa and India that cause devastating losses to poor farmers. We here describe the molecular diversity of seven representative cassava mosaic geminiviruses CMGs infecting cassava from multiple locations in Tanzania. We report for the first time the presence of two isolates in East Africa EACMCV- TZ1 and EACMCV- TZ7 of the species East African cassava mosaic Cameroon
