Figure 4From: Recombination hotspots and host susceptibility modulate the adaptive value of recombination during maize streak virus evolutionFitness assay of parental MSV genomes and recombinant MSV viruses. The viability of recombinant viruses compared to that of their chimaeric parents, and the wild-type viruses MSV-MatA and MSV-VW. Recombinants recovered from MSV-sensitive plants (cv. Golden Bantam) after agroinoculation with the pair MatMPCPVW+VWMPCPMat (A) and MatMPCPLIRVW+VWMPCPLIRMat (B) were tested in moderately-resistant maize (cv. STAR 7714). Mean chlorotic leaf areas (and the 95% confidence intervals of these estimates indicated by error bars) observed on leaves 4, 5 and 6 of symptomatic plants. Shown in blue and pink on the genome schematic are regions derived from MSV-VW and MSV-MatA, respectively. The genome regions are as indicated in the legend of Figure 1.Back to article page
