Reoviridae is a large family of viruses that can infect fungi, vertebrates, invertebrates, and plants. Within this family, members of the Phytoreovirus, Oryzavirus, and Fijivirus genera can multiply in several plant species and in arthropod vectors. In plants, they cause severe diseases that threaten crop production worldwide. Mal de Río Cuarto virus (MRCV) is a member of the genus Fijivirus that causes important losses in maize production in Argentina. This virus infects also wheat, barley, oat, and several grass weed species which constitute reservoirs of the virus throughout the year. In this virus the protein P9 is an essential part of the viroplasm. One of the major biological functions of viroplasm proteins is that they can recruit viral RNA transcripts for the synthesis of genomic dsRNA. Here you can see a recent low resolution cryoEM stucture of the P9 protein from the Mal del Rio Cuarto virus. The protein has a dodecamer structure formed by two hexameric stacked rings (PDB code: 7KVD)
