Review Citation - WoS: 10Citation - Scopus: 12Genetic and Biotechnological Approaches To Improve Fruit Bioactive Content: a Focus on Eggplant and Tomato Anthocyanins(Mdpi, 2024) Cammareri, Maria; Frary, Amy; Frary, Anne; Grandillo, SilvanaAnthocyanins are a large group of water-soluble flavonoid pigments. These specialized metabolites are ubiquitous in the plant kingdom and play an essential role not only in plant reproduction and dispersal but also in responses to biotic and abiotic stresses. Anthocyanins are recognized as important health-promoting and chronic-disease-preventing components in the human diet. Therefore, interest in developing food crops with improved levels and compositions of these important nutraceuticals is growing. This review focuses on work conducted to elucidate the genetic control of the anthocyanin pathway and modulate anthocyanin content in eggplant (Solanum melongena L.) and tomato (Solanum lycopersicum L.), two solanaceous fruit vegetables of worldwide relevance. While anthocyanin levels in eggplant fruit have always been an important quality trait, anthocyanin-based, purple-fruited tomato cultivars are currently a novelty. As detailed in this review, this difference in the anthocyanin content of the cultivated germplasm has largely influenced genetic studies as well as breeding and transgenic approaches to improve the anthocyanin content/profile of these two important solanaceous crops. The information provided should be of help to researchers and breeders in devising strategies to address the increasing consumer demand for nutraceutical foods.Article Citation - WoS: 179Citation - Scopus: 229Health Benefits and Bioactive Compounds of Eggplant(Elsevier, 2018) Gürbüz, Nergiz; Uluışık, Selman; Frary, Anne; Frary, Amy; Doğanlar, SamiEggplant is a vegetable crop that is grown around the world and can provide significant nutritive benefits thanks to its abundance of vitamins, phenolics and antioxidants. In addition, eggplant has potential pharmaceutical uses that are just now becoming recognized. As compared to other crops in the Solanaceae, few studies have investigated eggplant's metabolic profile. Metabolomics and metabolic profiling are important platforms for assessing the chemical composition of plants and breeders are increasingly concerned about the nutritional and health benefits of crops. In this review, the historical background and classification of eggplant are shortly explained; then the beneficial phytochemicals, antioxidant activity and health effects of eggplant are discussed in detail.Article Citation - WoS: 187Citation - Scopus: 212A Comparative Genetic Linkage Map of Eggplant (solanum Melongena) and Its Implications for Genome Evolution in the Solanaceae(Genetics Society of America, 2002) Doğanlar, Sami; Frary, Anne; Daunay, Marie-Christine; Lester, Richard N.; Tanksley, Steven D.A molecular genetic linkage map based on tomato cDNA, genomic DNA, and EST markers was constructed for eggplant, Solanum melongena. The map consists of 12 linkage groups, spans 1480 cM, and contains 233 markers. Comparison of the eggplant and tomato maps revealed conservation of large tracts of colinear markers, a common feature of genome evolution in the Solanaceae and other plant families. Overall, eggplant and tomato were differentiated by 28 rearrangements, which could be explained by 23 paracentric inversions and five translocations during evolution from the species' last common ancestor. No pericentric inversions were detected. Thus, it appears that paracentric inversion has been the primary mechanism for chromosome evolution in the Solanaceae. Comparison of relative distributions of the types of rearrangements that distinguish pairs of solanaceous species also indicates that the frequency of different chromosomal structural changes was not constant over evolutionary time. On the basis of the number of chromosomal disruptions and an approximate divergence time for Solanum, ∼0.19 rearrangements per chromosome per million years occurred during the evolution of eggplant and tomato from their last ancestor. This result suggests that genomes in Solanaceae, or at least in Solanum, are evolving at a moderate pace compared to other plant species.Article Citation - WoS: 196Citation - Scopus: 214Conservation of Gene Function in the Solanaceae as Revealed by Comparative Mapping of Domestication Traits in Eggplant(Genetics Society of America, 2002) Doğanlar, Sami; Frary, Anne; Daunay, Marie-Christine; Lester, Richard N.; Tanksley, Steven D.Quantitative trait loci (QTL) for domestication-related traits were identified in an interspecific F2 population of eggplant (Solanum linnaeanum × S. melongena). Although 62 quantitative trait loci (QTL) were identified in two locations, most of the dramatic phenotypic differences in fruit weight, shape, color, and plant prickliness that distinguish cultivated eggplant from its wild relative could be attributed to six loci with major effects. Comparison of the genomic locations of the eggplant fruit weight, fruit shape, and color QTL with the positions of similar loci in tomato, potato, and pepper revealed that 40% of the different loci have putative orthologous counterparts in at least one of these other crop species. Overall, the results suggest that domestication of the Solanaceae has been driven by mutations in a very limited number of target loci with major phenotypic effects, that selection pressures were exerted on the same loci despite the crops' independent domestications on different continents, and that the morphological diversity of these four crops can be explained by divergent mutations at these loci.
