Sharka disease, caused by the plum pox virus (PPV), negatively impacts stone fruit production, resulting in economic losses. It has been demonstrated that grafting almond (Prunus dulcis (Miller) D.A.

This study characterizes the metabolomic profiles of three reference apricot cultivars ('Bergeron', 'Currot', and 'Goldrich') using 1H NMR spectroscopy untargeted UPLC-QToF MS/MS to support plant breeding by correlating data with fruit phenotyping. The primary objective was identify quantify key metabolites influencing quality from a nutraceutical perspective. analysis revealed significant differences in secondary among cultivars. 'Bergeron' 'Goldrich' exhibited higher concentrations organic acids (109 mg/g malate 202 citrate 'Goldrich'), flavonoids such as epicatechin (0.44 0.79 mg/g, respectively), sucrose (464 546 mg/g), contributing their acidity-to-sugar balance. Conversely, 'Currot' showed levels amino (24.44 asparagine) sugars, particularly fructose glucose (79 180 enhancing its characteristic sweetness. These findings suggest that profiling can provide valuable insights into biochemical pathways underlying traits, aiding selection desirable characteristics. integration phenotyping offers comprehensive approach understanding diversity, crucial for high-quality, nutritionally enriched fruits meet market demands.

The main objective of this study was to monitor apricot development and ripening through gene expression analysis key candidate genes using the RT-qPCR technique. Eight cultivars were selected analyze phenological genetic patterns from pre-ripening stages postharvest. In addition, 19 analyzed in contrasting 'Cebas Red' 'Rojo Pasión' different (two preharvest S1 S2, one harvest stage S3, two postharvest S4 S5). This pool included related fruit growth ripening, associated with color, linked fruit's nutraceutical aspects. Among studied genes,
