Chinese wheat mosaic virus (CWMV)
This is a rod-shaped virus which infects wheat in China. The symptoms include stunting and leaf mosaic. It is a soil-borne virus and is transmitted by the slime mold Polymyxa graminis. CWMV has a bipartite single-stranded positive sense RNA genome. RNA1 is 7147 nt long and encodes three proteins required for viral replication and movement. RNA2 is 3564 nt long and believed to encode four proteins: the major capsid protein (CP, 19 kDa); two minor CP-related proteins (N-CP, 23 kDa and CP-RT, 84 kDa), as well as a cysteine-rich RNA-silencing suppressor (CRP, 19 kDa). Full-length cDNA clones of RNA1 and RNA2 have been constructed and are infectious in both wheat and N. benthamiana plants.
