Abstract |
In surveys of weed occurrence undertaken from 2006 to 2007, near to the Daegu experimental fields of the National Institute of Crop Science, plants belonging to 31 families, 74 genera and 96 species were found. For the investigation of the natural or alternative hosts of Soybean yellow mottle mosaic virus (SYMMV), 495 plant samples belonging to 26 families 84 species were subjected to RT-PCR. SYMMV was detected only from legume plants such as Glycine soja, Vigna angularis var. nipponensis, Trifolium repens, and Lespedeza cuneata. Among legume plants tested, more than a third of G. soja (wild soybean) contained SYMMV, indicating that the wild soybean played an important role as a reservoir of SYMMV. Wild soybeans may be infected with SYMMV as early as mid-July. Considering the results of early infection and the high infection rate of seed and seed transmission of SYMMV in G. soja, wild soybeans may have played an important role in the completion of disease cycle of the virus. |
