Molecular breeding of a novel orange-brown tomato fruit with enhanced beta-carotene and chlorophyll accumulation
BACKGROUND Tomatoes provide a significant dietary source of the carotenoids, lycopene and β-carotene. During ripening, carotenoid accumulation determines the fruit colors while chlorophyll degradation. These traits have been, and continue to be, a significant focus for plant breeding efforts. Previous work has found strong evidence for a relationship between CYC-B gene expression and the orange...
متن کاملInheritance of Beta Carotene Content in the Wild Tomato Species Lycoporsicon cheesmanii
Beta carotene and lycopene, the two principal colored carotenoids present in tomato fruit, were measured in mature fruit of parental, F,, F2, and backcross populations derived from an initial cross of an orange-fruited accession of the wild tomato species Lycopersicon cheesmann Riley with the cultivated tomato L esculentum Mill. Segregation patterns for fruit pigmentation and percentage beta ca...

متن کاملCarotene Hydroxylase Activity Determines the Levels of Both α-Carotene and Total Carotenoids in Orange Carrots.
The typically intense carotenoid accumulation in cultivated orange-rooted carrots (Daucus carota) is determined by a high protein abundance of the rate-limiting enzyme for carotenoid biosynthesis, phytoene synthase (PSY), as compared with white-rooted cultivars. However, in contrast to other carotenoid accumulating systems, orange carrots are characterized by unusually high levels of α-carotene...
متن کاملBeta-carotene content of certain organs from two patients receiving high doses of beta-carotene.
We measured carotene in the livers of two patients receiving beta-carotene therapy for photosensitivity. In both patients, the amount of carotene was within reported ranges for patients on normal diets; no abnormal amounts of beta-carotene had accumulated in the livers after oral administration of large amounts of beta-carotene. Light-microscopic examination of the liver (specimen obtained at c...
