Characterization of a Viral Synergism in the Monocot Brachypodium distachyon Reveals Distinctly Altered Host Molecular Processes Associated with Disease

Panicum mosaic virus (PMV) and its satellite virus (SPMV) together infect several small grain crops, biofuel, and forage and turf grasses. Here, we establish the emerging monocot model Brachypodium (Brachypodium distachyon) as an alternate host to study PMV- and SPMV-host interactions and viral synergism. Infection of Brachypodium with PMV+SPMV induced chlorosis and necrosis of leaves, reduced seed set, caused stunting, and lowered biomass, more...
