This knowledge will provide valuable guidance for the breeding of high-quality red-skinned and red-fleshed apple cultivars.Īllan AC, Hellens RP, Laing WA (2008) MYB transcription factors that colour our fruit. Furthermore, we will offer insights into the molecular mechanisms underlying anthocyanin biosynthesis in apples. We will also discuss the regulation of apple color development by external environmental factors such as light, temperature, and water. We will also cover key transcription factors, such as MYB, bHLH, and WD40 that are involved in the regulation of anthocyanin synthesis and of fruit color development in apples. In this chapter, we will discuss research efforts on the coloration of the apple fruit, including the development of important genomic databases to identify important genomic regions and genes, genetic and transcriptional factors that regulate pigment accumulation, environmental factors influencing anthocyanin synthesis, and current goals for breeding for red-skinned and red-fleshed apples. Fruit color development in apples is a major focus for both breeders and researchers as consumers associate brightly colored red apples with ripeness and good flavor. Apple ( Malus × domestica Borkh.) is one of the most widely produced and economically important fruits in temperate regions.
