Maize chlorotic mottle virus (MCMV) infection causes chlorosis and necrosis in maize leaves. a Genomic organization of MCMV. The heavy line indicates the genomic RNA and the thinner lines represent the subgenomic RNA1/2 (sgRNA1/2). Boxes indicate the coding regions and their open reading frames. The vertical lines (asterisks in red) indicate the leaky stop codons leading to translational readthrough. The dashed line (P7b) represents a non-AUG start codon. CP: coat protein. b, c Phenotypes in the first systemically infected maize leaves of mock-inoculated (b) or MCMV-inoculated (c) maize plants at 10 days post-inoculation (dpi). The red arrows indicate the necrotic regions. Bar, 10 cm
