Special Issue Information

Dear Colleagues,

Tomato (Solanum lycopersicum L.) is one of the most important horticultural crops worldwide due to its level of production and consumption. It is broadly recognized as a model crop for studying the genetics and physiology of climacteric fleshy fruits, as well as for the breeding methods of autogamous plant species. Morphological fruit traits influence the crop yield and determine the final commercial destination, either for fresh market use or processing. Tomato plays an important role in human nutrition since it has a reservoir of health-beneficial compounds, such as vitamins, essential amino acids, carotenoids, phytosterols, and minerals. Lycopene, the main carotenoid in the red tomato fruit, together with other phenolic compounds, has been shown to exhibit anti-inflammatory, antioxidant, and cardioprotective properties.

Today, tomato breeding for yield and its morphological and nutritional components is assisted by biotechnologies, such as the maker-assisted selection for mendelian traits and quantitative trait loci (QTL) analysis, genome-wide association studies (GWAS), map-based cloning, omics analysis, and gene or genome editing. Furthermore, the big data analytics that are emerging from high-throughput pheno- and genotyping are revealing new approaches and bioinformatics tools that will have a colossal impact on tomato breeding.

To highlight the state-of-the-art and recent advances in the field of genetics and breeding for fruit traits in tomato, this Special Issue welcomes novel research articles based on the utilization of bioinformatics tools, omic approaches, gene editing, and breeding methods used to improve biochemical and morphological fruit traits.

Insights into flavor formation during fruit ripening can guide the development of breeding strategies that balance consumer and producer needs. Cherry tomatoes possess a distinctive taste, yet research on quality formation is limited. Here, metabolomic and transcriptomic analyses were conducted on different ripening stages. The results revealed differentially accumulated metabolites during fruit ripening, providing candidate metabolites related to flavor. Interestingly, several key flavor-related metabolites already reached a steady level at the mature green stage. Transcriptomic analysis revealed that the expression levels of the majority of genes tended to stabilize after the pink stage. Enrichment analysis demonstrated that changes in metabolic and biosynthetic pathways were evident throughout the entire process of fruit ripening. Compared to disease resistance and fruit color genes, genes related to flavor and firmness may have a broader impact on the accumulation of metabolites. Furthermore, we discovered the interconversion patterns between glutamic acid and glutamine, as well as the biosynthesis patterns of flavonoids. These findings contribute to our understanding of fruit quality formation mechanisms and support breeding programs aimed at improving fruit quality traits. Full article

The elucidation of the ripening pathways of climacteric fruits helps to reduce postharvest losses and improve fruit quality. Here, we report an integrative study on tomato ripening for two near-isogenic lines (NIL115 and NIL080) with Solanum pimpinellifolium LA0722 introgressions. A comprehensive analysis using phenotyping, molecular, transcript, and protein data were performed. Both NILs show improved fruit firmness and NIL115 also has longer shelf life compared to the cultivated parent. NIL115 differentially expressed a transcript from the APETALA2 ethylene response transcription factor family (AP2/ERF) with a potential role in fruit ripening. E4, another ERF, showed an upregulated expression in NIL115 as well as in the wild parent, and it was located physically close to a wild introgression. Other proteins whose expression levels changed significantly during ripening were identified, including an ethylene biosynthetic enzyme (ACO3) and a pectate lyase (PL) in NIL115, and an alpha-1,4 glucan phosphorylase (Pho1a) in NIL080. In this study, we provide insights into the effects of several genes underlying tomato ripening with potential impact on fruit shelf life. Data integration contributed to unraveling ripening-related genes, providing opportunities for assisted breeding. Full article
