Rosaceae is the most important fruit-producing clade, and its key commercially relevant genera (Fragaria, Rosa, Rubus and Prunus) show broadly diverse growth habits, fruit types and compact diploid genomes. Peach, a diploid Prunus species, is one of the best genetically characterized deciduous trees. Here we describe the high-quality genome sequence of peach obtained from a completely homozygous genotype. We obtained a complete chromosome-scale assembly using Sanger whole-genome shotgun methods. We predicted 27,852 protein-coding genes, as well as noncoding RNAs. We investigated the path of peach domestication through whole-genome resequencing of 14 Prunus accessions. The analyses suggest major genetic bottlenecks that have substantially shaped peach genome diversity. Furthermore, comparative analyses showed that peach has not undergone recent whole-genome duplication, and even though the ancestral triplicated blocks in peach are fragmentary compared to those in grape, all seven paleosets of paralogs from the putative paleoancestor are detectable.

The present study investigates the genetic determinism of flowering and maturity dates, two traits highly affected by global climate change. Flowering and maturity dates were evaluated on five progenies from three Prunus species, peach, apricot and sweet cherry, during 3–8 years. Quantitative trait locus (QTL) detection was performed separately for each year and also by integrating data from all years together. High heritability estimates were obtained for flowering and maturity dates. Several QTLs for flowering and maturity dates were highly stable, detected each year of evaluation, suggesting that they were not affected by climatic variations. For flowering date, major QTLs were detected on linkage groups (LG) 4 for apricot and sweet cherry and on LG6 for peach. QTLs were identified on LG2, LG3, LG4 and LG7 for the three species. For maturity date, a major QTL was detected on LG4 in the three species. Using the peach genome sequence data, candidate genes underlying the major QTLs on LG4 and LG6 were investigated and key genes were identified. Our results provide a basis for the identification of genes involved in flowering and maturity dates that could be used to develop cultivar ideotypes adapted to future climatic conditions.

Peach flesh color is a monogenic trait with the white phenotype being dominant over the yellow; its expression has been reported to be determined by a carotenoid degradative enzyme. In the present study, a carotenoid cleavage dioxygenase (ccd4) gene was analyzed to test whether it can be responsible for the flesh color determinism. The analysis was conducted on chimeric mutants with white and yellow sectors of the fruit mesocarp; it was then extended to a pool of cultivars and a segregating F1 population. A ccd4 functional allele is consistently associated with the ancestral white flesh color; on the other hand, the yellow phenotype originated from at least three independent mutations disrupting ccd4 function, thus preventing carotenoid degradation. In addition, retro-mutations recovering ccd4 function and re-establishing the ancestral white flesh color were detected. Our results show that ccd4 is the gene controlling flesh color in peach; its expression results in the degradation of carotenoids in white-fleshed genotypes, while the yellow color arises as a consequence of its inactivation.

In apricot the bitter flavor of seeds is determined by the amount of amygdalin, a cyanogenic glucoside whose cleavage by endogenous enzymes, upon seed crushing, releases toxic hydrogen cyanide. The presence of such a poisonous compound is an obstacle to the use and commercialization of apricot seeds for human or animal nutrition. To investigate the genetic loci involved in the determination of the bitter phenotype a combined genetic and biochemical approach was used, involving a candidate gene analysis and a fine phenotyping via quantitative nuclear magnetic resonance, on an F1 apricot progeny. Seven functional markers were developed and positioned on the genetic maps of the parental lines Lito and BO81604311 and seven putative QTLs for the bitterness level were determined. In conclusion, this analysis has revealed some loci involved in the shaping of the bitterness degree; has proven the complexity of the bitter trait in apricot, reporting an high variance of the QTLs found over the years; has showed the critical importance of the phenotyping step, whose precision and accuracy is a pre-requisite when studying such a multifactorial character.

Within the ISAFRUIT European Integrated Project, a work package (6.1) is dedicated to the genetic bases of fruit quality and health properties. It is subdivided into six main tasks, two of them for the apricot and peach quality attributes: task 1 Identification and mapping of candidate genes for fruit quality in saturated maps of peach and apricot and task 3 QTLs analysis of fruit quality. Six laboratories are involved in theses tasks on Prunus species and 4 Prunus progenies of 120 seedlings each are being used: two apricot progenies grown in Avignon (F) and Bologna (I), and two peach progenies grown in Avignon and Bordeaux (F). Fruit quality characterization is based on (i) physical measurements (fruit weight, colour, firmness), (ii) biochemical measurements (soluble solids content, titratable acidity) and (iii) fine metabolic profiling based on 1 H RMN 1D targeting the major metabolites, associated with a phenolic compound characterization by HPLC. Saturated genetic linkage maps have been constructed for each progeny both in apricot and peach, and the phenotypic datasets will be joined with the genetic map for localising the associated QTLs. Identification and mapping of candidate genes for fruit quality traits will be the subsequent step. Particular attention will be paid to the co-linearity between species.
