Panicum mosaic virus (PMV) induces a mild mottle on millet plants, but the addition of its satellite virus (SPMV) causes a severe chlorosis and stunting. Immunoblots, RNA blots, and sucrose density gradient analyses revealed increases of PMV RNA and its p8 and capsid proteins when plants were co-infected with SPMV. A unique feature associated with this satellite virus interaction was an increased rate of systemic infection of PMV.
