Hypothesis
Can we identify the genetic basis for red flesh and foliage color in apple?
Conclusion
The study provides genetic evidence that red coloration in the fruit core and red foliage are controlled by a single locus named Rni.
Supporting Evidence
- The MdMYB10 gene co-segregates with the Rni locus.
- Red color in apple fruit and foliage is controlled by a single locus.
- Marker-assisted selection can accelerate the development of new apple varieties.
Takeaway
Scientists found a gene in apples that controls the red color of both the fruit and the leaves, which can help in breeding better apple varieties.
Methodology
The study involved mapping candidate genes in segregating populations and assessing phenotypic segregation for red color traits.
Limitations
The study did not identify a second gene controlling red cortex in the absence of red foliage.
