Maximizing saffron apocarotenoid production in varied tomato fruit carotenoid contexts

Abstract

SUMMARYSaffron spice owes its commercial appreciation to its specific apocarotenoids: crocins, picrocrocin, and safranal. In Crocus sativus, these compounds are biosynthesized from zeaxanthin through oxidative cleavage by the carotenoid cleavage dioxygenase 2 (CCD2). Transgenic tomato plants expressing CsCCD2 in the fruit, named Tomaffron, accumulate high levels of saffron apocarotenoids despite the low substrate availability for CsCCD2. In the present study, CsCCD2 has been introduced into Xantomato; this tomato variety accumulates high levels of zeaxanthin and β‐carotene in ripe fruit due to a combination of four mutant alleles. Xantomato and Tomaffron genotypes have been combined to optimize apocarotenoid production. The best transgenic lines accumulated 15 and 14 times more crocins and picrocrocin than Tomaffron, alongside a fourfold increase in β‐carotene compared to Xantomato, albeit at a cost in fruit yield. Segregation of the four mutations has been carried out to find the best combination for obtaining high levels of saffron apocarotenoids without adverse effects on fruit yield. Plants harboring the high‐pigmented 3 (hp3) and BETA (BSh) mutations accumulated 6 and 15 times more crocins and picrocrocin than Tomaffron, without observable pleiotropic effects. Additionally, those high levels of saffron apocarotenoids were obtained in fruit accumulating high levels of both lycopene and β‐carotene independently or in combination, suggesting a regulatory role for the apocarotenoids produced and indicating that it is possible to increase the levels of both types of healthy promoting molecules simultaneously.
