Resistance of tomato CCD8Cas9-edited T1 lines to the parasite infestation as compared to the wild type. To evaluate host resistance to the parasite, host roots of the tomato wild-type (WT) and CCD8Cas9 mutated T1 lines were rinsed after 3 months of infestation with P. aegyptiaca seeds. Tubercles larger than 2 mm in diameter were considered for analysis. (a) Number of P. aegyptiaca tubercles and shoots attached to the mutant and non-mutant tomato plants in the pot assay. Bars represent average of two experiments with four independent plants of each T1 line (irrespective of type of mutation, either homozygous or biallelic within the lines) ±SE values. (b) Representative images of parasite infestation of the host plant; WT shows number of parasites attached to the root while CCD8Cas9 mutants have reduced parasite infection. (c) Whole plant images of mutant lines 5 and 11 showing the parasite shoots and tubercles developed on those roots as compared to the WT plants. Red triangle indicates P. aegyptiaca shoots developed on host plant line 11, while host plant line 5 is free of P. aegyptiaca infestation.
