Sequencing results of T0 and T1 plants. In the T0 generation, DNA was extracted from a leaf for most plants and also from mixed tissues for some plants. The DNA was PCR amplified and sequenced. When the sequence was one type, the genotype was assumed to be homozygous mutants or WT. For the PCR products that contained mixed sequences, the DNA was cloned and each clone sequenced. In M/N, N is the number clones sequenced, and M is the number of clones showing a particular sequence. In the T1 generation, DNA was extracted and PCR amplified, and then sequenced without cloning. In M/N, N is the number of T1 plants examined, and M is the number of plants showing that particular genotype. WT, wild-type sequence with no mutation detected; d#, # of bp deleted from target site; d#a, same number of deletion at one site; d#b, same number of deletion at other sites; i#, # of bp inserted at target site; i#a, same number of insertion at one site; i#b, same number of insertion of different nucleotide at the same site; c#, combined mutation; s#, substitution; Non-homozygous mutation, more than one sequence detected in the sample and the sequencing chromatograms showed overlapped peaks. k: Lines in Kasalath background. The name of transgenic lines is in bold font. The mutations are marked using yellow color. The PAM motif (NGG) is marked by a grey box.
