“…In the GWAS for fruit colour and flesh colour , the most significant SNPs were identified on chromosome 3, which was expected because in previous studies, chromosome 3 is a hot spot for regulation of sweet cherry fruit colour [ 17 – 19 ]. For example, several overlapping QTLs are on chromosome 3 [ 19 ].…”

“…Molecular markers for valuable sweet cherry traits are rare and thus need to be developed and validated. Previously, the most precise approaches to identify QTLs associated with important traits used the cherry 6 + 9 K SNP array [ 19 , 27 ], with approximately one SNP per 86 kbp of genome. With the whole-genome sequencing used in this study, resolution was refined to one SNP per ~200 bp.…”

“…According to Lin-Wang et al [ 18 ], the same gene was associated with regulation of the anthocyanin biosynthetic pathway, and not only in sweet cherry. Overlapping QTLs for fruit skin and flesh colours have also been identified on chromosome 3 [ 19 ]. In addition, PavMYB10.1 gene polymorphism has been proposed as causative for fruit colour [ 20 ].…”

“…Traditional genetic mapping was initially used to identify QTLs with SSRs and cleaved amplified polymorphic sequences (CAPS) as molecular markers [ 10 , 11 , 17 , 24 ]. Recently, universal 6 K [ 8 ] and 6 + 9 K [ 27 ] single nucleotide polymorphism (SNP) arrays have been used to map QTLs of sweet and sour cherries [ 13 , 19 , 21 – 23 ]. Nevertheless, those approaches provide limited resolution in the gene-rich cherry genome.…”

In sweet cherry (Prunus avium L.), quantitative trait loci have been identified for fruit maturity, colour, firmness, and size to develop markers for marker-assisted selection. However, resolution is usually too low in those analyses to directly target candidate genes, and some associations are missed. In contrast, genome-wide association studies are performed on broad collections of accessions, and assemblies of reference sequences from Tieton and Satonishiki cultivars enable identification of single nucleotide polymorphisms after whole-genome sequencing, providing high marker density. Two hundred and thirty-five sweet cherry accessions were sequenced and phenotyped for harvest time and fruit colour, firmness, and size. Genome-wide association studies were used to identify single nucleotide polymorphisms associated with each trait, which were verified in breeding material consisting of 64 additional accessions. A total of 1,767,106 single nucleotide polymorphisms were identified. At that density, significant single nucleotide polymorphisms could be linked to co-inherited haplotype blocks (median size ~10 kb). Thus, markers were tightly associated with respective phenotypes, and individual allelic combinations of particular single nucleotide polymorphisms provided links to distinct phenotypes. In addition, yellow-fruit accessions were sequenced, and a ~90-kb-deletion on chromosome 3 that included five MYB10 transcription factors was associated with the phenotype. Overall, the study confirmed numerous quantitative trait loci from bi-parental populations using high-diversity accession populations, identified novel associations, and genome-wide association studies reduced the size of trait-associated loci from megabases to kilobases and to a few candidate genes per locus. Thus, a framework is provided to develop molecular markers and evaluate and characterize genes underlying important agronomic traits.

“…Consistently, PpMYB10.1 was required for the transcriptional activation of PpGST1 ; thus, both the genes are indispensable for the red tinge in red peaches [ 73 ]. PavMYB10 , a transcriptional regulator associated with color regulation, was reported as a candidate gene in sweet cherries ( Prunus avium L.) along with other color QTLs detected on linkage groups (LGs) 4 and 7 [ 74 ]. Another key gene-encoding NAC domain transcription factor designated as BLOOD (BL) found in high levels of blood-fleshed peaches activates PpMYB10.1 by forming a heterodimer with PpNAC .…”

Fleshy fruits are the most demanded fruits because of their organoleptic qualities and nutritional values. The genus Prunus is a rich source of diversified stone/drupe fruits such as almonds, apricots, plums, sweet cherries, peaches, and nectarines. The fruit-ripening process in Prunus involves coordinated biochemical and physiological changes resulting in changes in fruit texture, aroma gain, color change in the pericarp, sugar/organic acid balance, fruit growth, and weight gain. There are different varieties of peaches with unique palatable qualities and gaining knowledge in the genetics behind these quality traits helps in seedling selection for breeding programs. In addition, peaches have shorter post-harvest life due to excessive softening, resulting in fruit quality reduction and market loss. Many studies have been executed to understand the softening process at the molecular level to find the genetic basis. To summarize, this review focused on the molecular aspects of peach fruit quality attributes and their related genetics to understand the underlying mechanisms.
