Technical Abstract: Interpreting fruit metabolism, especially tree fruit, presents unique challenges. Long periods from tree establishment to fruiting render techniques directed towards reducing the complexity of metabolic mechanisms, such as genomic modification, relatively difficult. Consequently, holistic integrated genomics-based approaches have become attractive alternatives. Given the evident significance of gene-function and allosteric regulation by metabolites, comprehensive metabolic profiling or “metabolomics” is a necessary, integral facet of “omics” approaches. With an estimated 15,000 unique metabolites in a single plant species, metabolomics presents unique analytical challenges resulting from the extensive diversity of metabolite concentration, stability, polarity, solubility, and other physical properties. Instrument analysis and data extraction and evaluation techniques are, likewise, demanding. Nonetheless, comprehensive metabolic profiling can be used to reveal metabolic mechanisms, develop diagnostic biomarkers, and select markers to be employed for more informed breeding decisions.
