“…To date, there have been several DNA markers that discriminate MdMYB1-1 from MdMYB1-2 to MdMYB1-3 (Takos et al 2006;Yuan et al 2014;Zhang et al 2014). However, there were inconsistencies between genotype and phenotype, even in major well-known green cultivars such as 'Granny Smith'.…”

“…Several DNA markers discriminate MdMYB1-1 from others Moriya et al, 2017;Takos et al, 2006;Yuan et al, 2014;Zhang et al, 2014). At the moment, Mdo.chr9.4 , a simple sequence marker developed 16 kbp downstream from the transcription start site of MdMYB1 is thought to be the best marker to correctly distinguish MdMYB1 alleles.…”

Anthocyanin accumulation is responsible for the red color of the skin and flesh of apple fruits (Malus × domestica Borkh.), and redder fruits are more marketable. Pigmentation in the skin of apple fruit varies among different cultivars and is influenced by environmental factors, including temperature conditions and the level of sunlight irradiation. Because warmer temperatures suppress anthocyanin synthesis in the skin of apple fruit, there are increasing concerns that global warming may be detrimental to fruit pigmentation. Recent molecular studies have revealed that the MdMYB1 gene, which encodes a transcription factor, plays a critical role in regulating anthocyanin synthesis in both the skin and flesh of apple fruits. A marker-assisted selection process has been developed to identify MdMYB1 genotypes and predict those fruits that will develop redder skin. These apples may be better adapted to a warmer global climate. The application of hormones can also increase the level of pigmentation in fruit skin, and plant growth regulators such as ethylene and jasmonate are commercially available. The mechanisms that regulate anthocyanin biosynthesis in the flesh of red-fleshed apple fruit appear to partially differ from those that function in the skin of red-skinned fruit. In the flesh of red-fleshed fruit, the pigment accumulates under dark conditions, whereas no anthocyanin is synthesized in the skin of bagged apple fruit. Conversely, in both red-skinned and red-fleshed apple fruits, warmer temperatures inhibit anthocyanin accumulation. Further studies on the regulation of anthocyanin synthesis in the flesh of red-fleshed apple fruit are necessary.

“…Biosynthesis of apple anthocyanins is controlled at the level of gene expression by the transcription factor MdMYB1 [Takos et al, 2006(also called MdMYBA in Ban et al, 2007] in cooperation with bHLH and WD40 transcription factors (Espley et al, 2007). This MYB gene also produces a red-fleshed phenotype in apple through the allelic variant MdMYB10 (Espley et al, 2007;Zhang et al, 2014).…”

ADDITIONAL INDEX WORDS. fruit color, anthocyanin biosynthesis, MYB transcription factors, controlled environment chambers ABSTRACT. The market value of the apple (Malus ·domestica Borkh.) cultivar Ambrosia is closely linked to the characteristic blush on the skin surface. For 'Ambrosia' orchards that produce consistently low levels of surface blush, the implementation of reflective rowcovering has improved surface coloration, but the reflected wavebands responsible for this enhanced color production have not been confirmed. This study consisted of two separate experiments: one conducted in the field to confirm reflective rowcovering efficacy and the other in a controlled environment cabinet to determine which waveband was enhancing red blush production. The red blush production in orchards with and without reflective rowcovering was then directly compared with the red blush produced on the surface of apples that were poorly colored at harvest and then exposed to visible, fluorescent, ultraviolet A (UVA), or ultraviolet B (UVB) light sources within the controlled environment chamber. Consequent analysis of the red blush color within the Commission Internationale de l'Eclairage a* and b* color space was conducted to evaluate the quality of the red blush pigment under each treatment in the field and the controlled environment chamber. The analysis revealed that the red blush that developed on apples from the reflective rowcover treatment most closely matched the red blush that developed in response to UVB exposure in the controlled environment cabinet. Further analysis of gene expression and anthocyanin contents in the 'Ambrosia' apples support the hypothesis that the primary driver for the characteristic red blush development, when reflective rowcovers are used, is increased exposure to UVB light.
