Fade into you: genetic control of pigmentation patterns in red-flesh apple (<i>Malus domestica</i>).

ABSTRACT: The genetic basis of type 1 red-flesh color development in apple (Malus domestica) depends upon a particular allele of the MdMYB10 gene. Interestingly, type 1 red-flesh apples are fully red after fruit set, but anthocyanin pigmentation in apple fruit cortex may decrease during fruit growth and maturation, leading to variable red patterning and intensities in the mature cortical flesh. We developed a histogram-based color analysis method to quantitatively estimate pigmentation patterns. This methodology was applied to investigate the phenotypic diversity in four hybrid F1 families segregating for red-flesh color. Pigmentation patterns were found to be heritable allowing the identification of a new locus by QTL analysis. To further investigate the mechanisms involved in the spa
