    Abstract/Description
    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 occidentalis, Leucana leucocephala and Glycine max), castor oil plant (Ricinus communis), a weed host (Combretum confertum) and a wild species of cassava (Manihot glaziovii) were determined. All ACMV isolates from these hosts showed 96–98% nucleotide sequence identity with cassava isolates from West Africa. EACMCV was found only in four hosts (S. occidentalis, L. leucocephala, C. confertum, M. glaziovii), and sequences of these isolates showed 96–99% identity with cassava isolates from West Africa. These results provide definitive evidence for the natural occurrence of ACMV and EACMCV in plant species besides cassava.

      The occurrence of African cassava mosaic virus and East African cassava mosaic Cameroon virus in natural hosts other than cassava in Nigeria 

      Alabi, O.J.; Ogbe, F.O.; Bandyopadhyay, Ranajit; Dixon, Alfred G.O.; Hughes, J.; Naidu, R.A. (2007)
      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. Based on PCR tests using virus-specific primers, a leguminous plant Senna occidentalis and the weed Combreturn confertumwere previously identified as natural hosts for ACMV and EACMCV and castor oil plant ...

      Multiplex PCR for the detection of African cassava mosaic virus and East African cassava mosaic Cameroon virus in cassava 

      Alabi, O.J.; Kumar, P.L.; Naidu, R.A. (2008)
      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 down stream virus-specific primers were designed for simultaneous amplification of 368 base pair (bp) and 650 bp DNA fragments specific to the replicase gene of ACMV and EACMCV, respectively. Similarly, ...

      First report of the occurrence of African cassava mosaic virus in a mosaic disease of soybean in Nigeria 

      Mgbechi-Ezeri, J.U.; Alabi, O.J.; Naidu, R.A.; Kumar, P.L. (2008)
      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 Manihot species, Jatropha multifida, and Ricinus communis L. in Euphorbiaceae, and Hewittia sublobata in Convolvulaceae. The experimental host range of ACMV includes Nicotiana sp. and Datura sp. in the Solanaceae ...
