Sammanfattning

Tomato is the most widely consumed vegetable worldwide. Heirloom (traditional and open-pollinated germplasm) tomatoes are prized for their long shelf-life, juiciness, unique texture, flavors, shapes, colors, and taste. They show a wealth of diversity, passed down through generations by seed savers to carry the family tradition of preserving unique germplasm. Heirloom tomatoes are rich in phenolics, flavonoids, carotenoids, and volatile compounds that contribute to their unique flavor and taste. Over 400 volatile compounds, 60 primary and secondary metabolites, 17 associations influencing 13 primary and 19 secondary metabolites, 4 genomic regions housing clusters of associations controlling variations in metabolites, and potential candidate genes implicated in modulating the metabolites crucial for human diet and fruit consumptions were unlocked. Key alleles associated with unique tomato flavor were identified. These advances provide unique opportunities to restore some of the tomato flavor lost through domestication or because of the genetic improvement of modern tomatoes. Environmental conditions, crop management practices, postharvest, and processing technologies, in addition to genetics, contribute to unique tomato taste and flavor that must be taken care of while producing tomatoes for consumption. Cataloguing and profiling of heirloom germplasm for metabolites and textural traits must be done on a priority basis to preserve such unique landraces for enhancing flavor and taste of modern tomatoes. CRISPR/Cas9 systems hold great promise to accelerate the development of tomatoes with unique flavor and taste.
