Purple Tomatoes: Longer Lasting, Less Disease, and Better for You
نویسنده
چکیده
A new study demonstrates that tomato fruits engineered for high anthocyanin accumulation have extended shelf life and are less susceptible to a fungal pathogen. These phenotypes are related to the increased antioxidant capacity of the fruits and shed light on the role of oxidative processes in the later stages of fruit ripening.

P35: How to Manage Anxiety
Anxiety is a mental state that is elicited in anticipation of threat or potential threat. Sensations of anxiety are a normal part of human experience, but excessive or inappropriate anxiety can become an illness. Anxiety is part of the normal human experience. We may speculate that it served human survival during evolution by enhancing preparedness and alertness. However, anxious manifestations...
متن کاملDiallel Analysis for Lycopene Content in the Hybrids Derived from Different Colored Parents in Tomato
Lycopene is a red pigment in tomato with purported antioxidant properties. As the amount of lycopene has been reported to differ in different colored tomatoes or even absent in non-red tomatoes, the objective of this study was to investigate the inheritance of lycopene content and the color parameters of hybrids using a 10 parent diallel excluding reciprocals. Parents differed in general combin...
متن کاملAnthocyanins Double the Shelf Life of Tomatoes by Delaying Overripening and Reducing Susceptibility to Gray Mold
Shelf life is an important quality trait for many fruit, including tomatoes. We report that enrichment of anthocyanin, a natural pigment, in tomatoes can significantly extend shelf life. Processes late in ripening are suppressed by anthocyanin accumulation, and susceptibility to Botrytis cinerea, one of the most important postharvest pathogens, is reduced in purple tomato fruit. We show that re...
متن کاملCarbon nanotubes provide longer lasting gastroprotective effects for anandamide in stress-induced gastric ulcer in rat
Introduction: Anandamide (AEA) has shown a wide spectrum of pharmacological activities including the effects against the peptic ulcer, meanwhile, the poor solubility or short half-life may negatively affect the effectiveness of this valuable cannabinoid. Based on the superior properties of carbon nanotubes (CNTs) for controlled drug delivery, we aimed to prepare AEA-CNTs complex and evaluat...
متن کاملPurple as a tomato: towards high anthocyanin tomatoes.
Anthocyanins are naturally occurring pigments ubiquitously present in plants and, as such, part of the human diet. Owing to their biological activity, anthocyanins have beneficial health effects but, unfortunately, are not present in some important crop plants, such as tomatoes. Recently, a 'purple' tomato, highly enriched with anthocyanins, was produced by the ectopic expression of two selecte...
