Anthocyanin concentration is an important determinant of the colour of many fruits. In apple (Malus x domestica), centuries of breeding have produced numerous varieties in which levels of anthocyanin pigment vary widely and change in response to environmental and developmental stimuli. The apple fruit cortex is usually colourless, although germplasm does exist where the cortex is highly pigment...

Using RNA-seq, this study analysed an apple (Malus×domestica) anthocyanin-deficient yellow-skin somatic mutant 'Blondee' (BLO) and its red-skin parent 'Kidd's D-8' (KID), the original name of 'Gala', to understand the molecular mechanisms underlying the mutation. A total of 3299 differentially expressed genes (DEGs) were identified between BLO and KID at four developmental stages and/or between...

MdMYB10 gene expression results in accumulation of anthocyanin in many tissues including flesh of applefruit. The MdMYB1 and MdMYBA genes are close homologues to MdMYB10 gene and both are responsiblefor red color phenotype in apple fruit skin. In the current study, an apple genome sequence draft analysisindicated that these three genes are located in a unique contig. Further a...

Background: Integrating plant genomics and classical breeding is a challenge for both plant breeders and molecular biologists. Marker-assisted selection (MAS) is a tool that can be used to accelerate the development of novel apple varieties such as cultivars that have fruit with anthocyanin through to the core. In addition, determining the inheritance of novel alleles, such as the one responsib...

In apple (Malus domestica), red coloration is an attractive trait for consumers. The color of fruit skin determined by the distribution carotenoids and anthocyanins in tissue. ‘Fuji’ apples have stripes over a yellow-green background, ‘Mishima’, bud sport variety, has superior compared to its parent. To investigate genetic mechanism underlying enhanced pigmentation ‘Mishima’ skin, we characteri...

Apple is a major fruit crop grown worldwide and provides humans with an essential diet health benefits. One of the benefits related to accumulation anthocyanin, which also attractive red colour. It known that MdMYB10 allele containing transposable element (TE) insertion in its promoter (termed Red-TE allele) underlies anthocyanin colouration skin cultivated apples. However, distribution this wi...
