Panicum Mosaic Satellite Virus
Lambert M. SurhoneISBN: 978-6-1329-2602-9;
Panicum mosaic satellite virus (SPMV) is a plant satellite virus. It only infects grasses which are infected by Panicum mosaic virus. One study found that 72% of Stenotaphrum secundatum (St Augustine grass) infected with panicum mosaic virus was also infected with SPMV. In addition to SPMV, many plants infected with panicum mosaic virus are also infected with satellite RNAs.A satellite is a subviral agent composed of nucleic acid that depends on the coinfection of a host cell with a helper or master virus for its multiplication. When a satellite encodes the coat protein in which its nucleic acid is encapsidated it is referred to as a satellite virus. A satellite virus of mimivirus that inhibits the replication of its host has been termed a virophage.
