Nweke, F.; Lutete, D.; Dixon, A.; Ugwu, B.; Ajobo, O.; Kalombo, N.; Bukaka, B. (2000)The importance of cassava relative to other crops in the cropping system was almost total; cassava was present in 70% of arable fields; maize and beans or peas were each present in 13% of arable fields and all other crops were present in 4%. Cassava was produced mostly for sale, yet it was not as important around market centers as in remote areas because imported rice and wheat products were easily accessible. Cassava land area was not expanding in many of the villages visited because of low-level ...
Molecular biodiversity of cassava begomoviruses in Tanzania: evolution of cassava geminiviruses in Africa and evidence for East Africa being a center of diversity of cassava geminiviruses Ndunguru, J.; Legg, J.P.; Aveling, T.; Thompson, G.; Fauquet, Claude M. (2005)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 virus, originally described in West Africa. The complete nucleotide sequence ...
