Other claims from this paper (7)
- Observation Walnut cultivar HT-14 had the highest embryogenic induction (53.33%) among the cultivars screened.
- Observation Walnut cultivar HT-14 had the highest regeneration efficiency (85.33%) among the cultivars screened.
- Observation The 35S:RUBY construct was effectively expressed in somatic embryos of the HT-14 genotype.
- Intervention effect Endogenous promoters significantly increased walnut mutation efficiencies compared with commonly used exogenous promoters.
- Observation The JrU3-chr3 promoter achieved an editing efficiency of 58.82% in walnut.
- Intervention effect Endogenous promoters promoted higher frequencies of homozygous and biallelic mutations than exogenous promoters.
- Intervention effect Endogenous promoters promoted greater mutation diversity in walnut.
