Diversity of begomoviruses associated with mosaic disease of cultivated cassava (Manihot esculenta Crantz) and its wild relative (Manihot glaziovii Mull. Arg.) in Uganda
Cassava (Manihot esculenta) growing in Uganda during 2001–2002 has been screened for the presence of begomoviruses using PCR-RFLP, cloning full-length genomic components and nucleotide sequence analysis. In contrast with a recent survey in neighbouring Kenya, which identified three distinct strains...

| description | Cassava (Manihot esculenta) growing in Uganda during 2001–2002 has been screened for the
presence of begomoviruses using PCR-RFLP, cloning full-length genomic components and
nucleotide sequence analysis. In contrast with a recent survey in neighbouring Kenya, which
identified three distinct strains of East African cassava mosaic virus (EACMV, EACMV-UG and
EACMV-KE2) as well as East African cassava mosaic Zanzibar virus and the new species East
African cassava mosaic Kenya virus, only EACMV-UG and, to a lesser extent, African cassava
mosaic virus (ACMV) were found associated with cassava in Uganda. The integrity of the cloned
genomic components of representative virus isolates was confirmed by demonstrating their
infectivity in Nicotiana benthamiana and cassava using biolistic inoculation, providing a convenient
means to screen cassava varieties for disease resistance. Both EACMV-UG and ACMV were also
associated with Manihot glaziovii. Infectivity studies using cloned components confirmed that
viruses from one host could infect the other, suggesting that this wild relative of cassava might be
a reservoir host for the disease. The relatively low level of diversity of begomoviruses associated
with cassava mosaic disease in Uganda is consistent with reports that EACMV-UG has
displaced other begomovirus species and strains during the recent epidemic that swept through
the country. |
