Deficient copper availability on organoleptic and nutritional quality of tomato fruit

Copper (Cu) is an essential micronutrient for plants because it functions as a redox-active cofactor in vital processes inside the cells. Arable lands are often deficient in micronutrient contents and require the application of enriched fertilisers, whose overuse poses a high risk for human health, the environment and the food safety. Here, we aimed to decipher the effects of Cu deficiency during fruit growth on Cu and other micronutrients contents and on the fruit nutritional value and quality of tomato, the most consumed fruit worldwide, throughout the maturation process. Changes in the contents of important micronutrients for fruit physiology and human health, such as Fe and Mn, occurred in response to Cu deficient growing conditions at different fruit ripening stages, while lower Cu levels were detected in those fruit along the whole maturation process. Cu deficiency delayed changes in lycopene content and fruit colour, but increased acidity, and advanced the rise in antioxidant capacity and vitamin C content during fruit colour change from green to light red in the Moneymaker tomato; although this time lag eventually caught up in the most mature fruit stage. Cu deficiency also increased total phenolic and flavonoid contents only in green fruit.
