Verbascum species as a new source of saffron apocarotenoids and molecular tools for the biotechnological production of crocins and picrocrocin

Abstract: SUMMARYCrocins are glucosylated apocarotenoids present in flowers and fruits of a few plant species, including saffron, gardenia, and Buddleja. The biosynthesis of crocins in these plants has been unraveled, and the enzymes engineered for the production of crocins in heterologous systems. Mullein (Verbascum sp.) has been identified as a new source of crocins and picrocrocin. In this work, we have identified eight enzymes involved in the cleavage of carotenoids in two Verbascum species, V. giganteum and V. sinu… Show more

“…10 Recently, the content of carotenoids and apocarotenoids was evaluated in the flowers of two Verbascum species, V. sinuatum and V. giganteum (Morote et al, 2023a). 43 Crocins concentration in the flowers of both species are around 11 to 14 mg g −1 DW. Both species have a broad distribution in the Iberian Peninsula and grow in two completely different habitats with a preference for dry soils.…”
