Comparative Analysis of Antiviral Responses in Brachypodium distachyon and Setaria viridis Reveals Conserved and Unique Outcomes Among C₃ and C₄ Plant Defenses

Viral diseases cause significant losses in global agricultural production, yet little is known about grass antiviral defense mechanisms. We previously reported on host immune responses triggered by Panicum mosaic virus (PMV) and its satellite virus (SPMV) in the model C 3 grass Brachypodium distachyon. To aid comparative analyses of C 3 and C 4 grass antiviral defenses, here, we establish B. distachyon and Setaria viridis (a C 4 grass) as...
