Abstract:

The aims were to obtain the pathogenic sequence of mulberry mosaic dwarf disease in Ankang area, and provide more information on the control of the disease. The pathogen of mulberry mosaic dwarf disease in Ankang area was isolated by RT-PCR, and the secondary structure was predicted in Mfold web. The length of the pathogen, MMDVd-201110151 (GenBank accession number: JQ809700), was 357 bp, and the GC percent was 50.7% in it. The 38 bp behind 219 bp had 85% identity with cscRNA1.150. The secondary structure of MMDVd-201110151 was predicted in Mfold web, 58.3% pairs in the secondary structure, and the two ends in it were both branched. The pathogen of mulberry mosaic dwarf disease in Ankang area was isolated successfully.
