Figure 2. Tomato SNPs assay for crossover and non-crossover events.

Figure 2

(a) An homozygote M82 CRISPR mutant (+A, +A) expressing 35S:Cas9 and u6-26:Ps#2-sgRNA was crossed with S. pimpinellifoliumLA1578. The F1 is expected to give red fruits without DNA DSB and yellow fruit in case that the break was repaired by NHEJ, non-crossover or crossover. The SNPs pattern is allowing differentiating between repair mechanisms. Triangles are for SNPs; lightning mark the DSB site; blue line is for NHEJ indels. (b) Analysis of DNA DSB flanking markers in F2 and F3 plants. Red- homozygote for S. pimpinellifoliumLA1578 SNPs; yellow- homozygote for M82 SNPs (including the +A CRISPR-Cas9 mutant); orange- heterozygote; empty cells are for missing data; lightning- DSB site.
