Other claims from this paper (5)
- Association Genetic linkage in a biparental population confirmed that the same interval was linked to the PF phenotype.
- Observation Ten putative candidate genes were identified in the PF region.
- Observation Allele mining of 17 genotypes highlighted a CCCH-type zinc finger gene and a ubiquitin-specific protease gene as high-priority candidates.
- Observation Regulatory 3' UTR polymorphisms were identified in the zinc finger homolog.
- Method / resource Two KASP markers predicted the PF phenotype with over 96% accuracy in 494 tetraploid blackberries.
