Genotypic variability of carotenoids in traditional tomato cultivars.
Traditional varieties constitute a wide source of genetic variation that can be used per se or to obtain new cultivars with high consumer appeal and nutritional value. This work focuses on the carotenoid and chlorophyll profiles and contents of 53 traditional tomato cultivars, paying particular attention to compounds with recognized health-promoting properties. The study includes fruits with different shapes (oblate, slightly flattened, rounded, heart-shaped, long oblong and pyriform), colors (yellow, pink and red) and sizes (very small to very large). In addition, black colored tomato fruits with yellow, pink or red background color were studied. The highest concentrations of lycopene, β-carotene, phytoene and phytofluene were found in pink and red tomatoes, while the highest concentrations of lutein, violaxanthin, neoxanthin and chlorophylls were found in fruits with a dark coloration, regardless of their background coloration. Finally, the highest concentrations of the studied compounds as a whole (except β-carotene) were found in red- and pink-black varieties. Findings will hopefully contribute to recovering many tomato traditional varieties for use, directly in the field or as donor parents for breeding programs, to increase the nutraceutical properties of commercial varieties.

The roles of isomers of phytoene, phytofluene and zeta-carotene in carotenoid biosynthesis by a mutant strain of Scenedesmus obliquus.
Considerable changes in pigment composition occur during a period of 10 h when dark-grown cultures of PG1, a zeta-carotenic strain of Scenedesmus obliquus, are illuminated. These changes are consistent with a biosynthetic pathway in which 15-cis-phytoene is converted via 15-cis-phytofluene and 15-cis-zeta-carotene into all-trans-zeta-carotene and trans-bicyclic carotenoids. The findings also support the view that the xanthophylls lutein and zeaxanthin are formed from the corresponding carotenes and are especially important in the development of a normal chloroplast structure.
