Cassava mosaic disease: a curse to food security in subSaharan Africa
Banana bunchy top virus (BBTV) was first reported from sub-Saharan Africa (SSA) from Democratic Republic of Congo (DRC) in the 1950s, has become invasive and spread into 11 countries in the region. To determine the potential threat of BBTV to the production of bananas and plantains (Musa spp.) in...

Cassava mosaic disease (CMD) in Africa is caused by six distinct cassava mosaic viruses (family eminiviridae, genus Begomovirus). Among them, African cassava mosaic virus (ACMV) and East African cassava mosaicCameroon virus (EACMCV) have been reported in CMD-infected cassava plants in Nigeria. Ba...

A multiplex PCR was developed for simultaneous detection of African cassava mosaic virus (ACMV) and
East African cassava mosaic Cameroon virus (EACMCV) in cassava affected with cassava mosaic disease
(CMD). One set of three primers consisting of an upstream primer common for both viruses and two

Cassava mosaic disease (CMD) caused by African cassava mosaic virus (ACMV) and East African cassava mosaic Cameroon virus (EACMCV) is the major constraint to cassava production in Nigeria. Sequences of the DNA-A component of ACMV and EACMCV isolates from leguminous plant species (Senna occidental...
African cassava mosaic virus (ACMV; genus Begomovirus, family Geminiviridae) is one of six viruses documented in cassava (Manihot
esculenta Crantz.) plants showing cassava mosaic disease in sub-Saharan Africa (SSA). In addition to cassava, the natural host range of
ACMV includes a few wild Maniho...

Two new ‘legumoviruses’ (genus Begomovirus; family Geminiviridae) naturally infecting soybean (Glycine max L. Merr.) in Nigeria were molecularly characterized. Based on characteristic symptoms in soybean, the two viruses are provisionally designated as Soybean mild mottle virus (SbMMV) and Soybea...
