Altered Levels of Aroma and volatiles by Metabolic Engineering of Shikimate Pathway Genes in Tomato Fruits
The tomato (Solanum lycopersicum) fruit is an excellent source of antioxidants, dietary fibers, minerals and vitamins and therefore has been referred to as a “functional food”. Ripe tomato fruits produce a large number of specialized metabolites including volatile organic compounds. These volatiles serve as key components of the tomato fruit flavor, participate in plant pathogen and herbivore d...
متن کاملMetabolic Fingerprinting to Assess the Impact of Salinity on Carotenoid Content in Developing Tomato Fruits
As the presence of health-promoting substances has become a significant aspect of tomato fruit appreciation, this study investigated nutrient solution salinity as a tool to enhance carotenoid accumulation in cherry tomato fruit (Solanum lycopersicum L. cv. Juanita). Hereby, a key objective was to uncover the underlying mechanisms of carotenoid metabolism, moving away from typical black box rese...
متن کاملXanthophyll (lutein, zeaxanthin) content in fruits, vegetables and corn and egg products
Lutein and zeaxanthin are carotenoids that are selectively taken up into themacula of the eye where they are thought to protect against the development of age-related macular degeneration. Current dietary databasesmake it difficult to ascertain their individual roles in eye health because their concentrations in foods are generally reported together. The objective of this work is to determine t...
متن کاملMetabolic engineering of tomato fruit organic acid content guided by biochemical analysis of an introgression line.
Organic acid content is regarded as one of the most important quality traits of fresh tomato (Solanum lycopersicum). However, the complexity of carboxylic acid metabolism and storage means that it is difficult to predict the best way to engineer altered carboxylic acid levels. Here, we used a biochemical analysis of a tomato introgression line with increased levels of fruit citrate and malate a...
متن کاملEnhanced levels of the aroma and flavor compound S-linalool by metabolic engineering of the terpenoid pathway in tomato fruits.
The aromas of fruits, vegetables, and flowers are mixtures of volatile metabolites, often present in parts per billion levels or less. We show here that tomato (Lycopersicon esculentum Mill.) plants transgenic for a heterologous Clarkia breweri S-linalool synthase (LIS) gene, under the control of the tomato late-ripening-specific E8 promoter, synthesize and accumulate S-linalool and 8-hydroxyli...
