Resumen:
Most of the commercial cultivated tomatoes in Argentina are imported hybrids. Given that these tomatoes have been mainly selected for long shelf life and pest resistance, consumers are complaining about their taste and flavor. Therefore, tomato populations cultivated by inhabitants from Argentine Andean Valleys were analyzed in this work in an attempt to incorporate these varieties with better consumer preferences to the local and regional breeding programs. For this purpose a transcriptomic approach was used to evaluate transcriptional differences in red fruit varieties of contrasting flavor as previously determined by sensory analysis. In a global analysis, we observed ca. 45% of genes with a significantly differential expression between a bad flavor variety and the others tested. Functional classification of the transcripts differentially expressed was performed using the tool MapMan. Interestingly, one of these accessions of salient organoleptic characteristics has an increment in expression of genes associated with cell wall degradation and AA transport. In addition, a global correlation between transcript and metabolite profiles evidencing relevant relationships among them will be presented
