PCR detection of CMV from cassava plantations in China. DNA gel electrophoresis of PCR amplification from cassava samples collected from different provinces in China using primer pairs of UPA/UPB (a) and SPA/SPB (b). GD, Guangdong Province; GZ, Guizhou Province; HN, Hainan Province; GX, Guangxi Province; FJ, Fujian Province; C–, healthy cassava; C+, SLCMV-Col-infected cassava; M, DNA marker (2000 bp). c DNA sequencing chromatogram of PCR product for a single cassava sample (HN10, HN24, FJ2, or FJ4). A few double peaks in the chromatogram (marked by red arrows in AC1 gene) indicate co-infection of SLCMV-Col and SLCMV-HN7 in a single sample. Alignment of SLCMV-HN7 and SLCMV-Col AC1 nucleotide acid sequence shown in bottom panel
