Table showing disease severity for wild type and selected Tn5 mutants of Pfv based on their rating score in C. quinoa plants. A two-tailed, paired ‘t’ test with 95% of confidence intervals for independent means was performed between the wild type and each of Tn5 mutants. ^a; significant difference to WT at P <0.05.
