Title

Other claims from this paper (5)
- Observation Several DAM genes were identified on different chromosomes of the apple genome sequence.
- Observation Apple trees lacking functional MdDAM1 or MdDAM4 failed to enter dormancy.
- Observation Of 732 regenerated shoot lines from CRISPR/Cas editing of MdDAM1, 60 showed mutations.
- Observation None of the mutated lines had both alleles of MdDAM1 mutated.
- Observation A second regeneration step yielded 17 lines with uniform biallelic MdDAM1 mutations.
