Cocksfoot mottle virus (CfMV) is a pathogenic plant virus belonging to the genus Sobemovirus. The virus appears in southern and central England . It is transmitted by beetles Lema melanopa and Lema lichenis and is common in crops of cocksfoot and cocksfoot/legume mixtures.[1]
Molecular biology
CfMV's P1 protein, required for infection, has been found to interfere with RNAi pathways in plants species such as Nicotiana benthamiana and Nicotiana tabacum.[2]
The polyprotein coat of CfMV is made up of two proteins, encoded by overlapping open reading frames (2a and 2b) which are transcribed through a ribosomal frameshift mechanism.[3] This mechanism is reliant upon a small stem-loop structure and a 'slippery' repeat sequence which allows programmed ribosomal frameshifting.[4]
