Development of zeaxanthin‐rich tomato fruit through genetic manipulations of carotenoid biosynthesis

This work employed two genetic approaches in order to enhance zeaxanthin biosynthesis in tomato fruit: a transgenic metabolic engineering and classical genetic breeding, which resulted in a nontransgenic tomato line, named ‘Xantomato’, which comprised ca.

Natural variation for carotenoids in fresh kernels is controlled by uncommon variants in sweet corn

Genomic prediction models with genome‐wide markers obtained moderately high predictive abilities for the carotenoid traits, especially lutein, and outperformed models with less markers that targeted candidate genes implicated in the synthesis, retention, and/or genetic control of kernel carotanoids.

Unravelling the Effect of Provitamin A Enrichment on Agronomic Performance of Tropical Maize Hybrids

The study showed that breeding for enhanced provitamin A content had no adverse effect on grain yield in the biofortified hybrids evaluated in the regional trials, and highlighted the possibility of developing broadly adapted hybrids containing high levels of beneficial carotenoids for commercialization in areas with variable maize growing conditions in Africa.

Vegetable breeding as a strategy of biofortification in carotenoids and prevention of vitamin A deficiency

The objective of this review is addressing the problems resulting from vitamin A deficiency and the adoption potential of horticulture species by genetic breeding programs aiming the biofortification in carotenoids.

Thermal Isomerization and Degradation Behaviours of Carotenoids in Simulated Sweet Corn Juice

The thermal behaviour of carotenoids may affect the nutritional value and flavour quality of sweet corn juice. In this study, carotenoid compositions and volatile components in simulated sweet corn

Variability in Prolificacy, Total Carotenoids, Lutein, and Zeaxanthin of Yellow Small-Ear Waxy Corn Germplasm

The variability of ear prolificacy, total carotenoids, lutein, zeaxanthin, and beta-carotene among yellow small-ear waxy corn accessions is explored to suggest that a higher chance of secondary ears becomes marketable ears with an increase of total ears per plant per hectare.

Postharvest Storage of Reddish-Purple Sweetcorn: Changes in Anthocyanin, Starch and Sugar Content during Ambient and Refrigerated Storage

Reddish-purple sweetcorn has recently been developed by our laboratory through the inclusion of an active anthocyanin biosynthesis pathway in white sweetcorn. Anthocyanin is not only responsible for

Biofortification of vegetables for the developed world

Increasing the nutritional value of fruits and vegetables through biofortification, or increasing their nutrient density, is an attractive means of increasing nutrition without necessarily increasing intake.

Screening sweetcorn for enhanced zeaxanthin concentration.

The use of a hue angle of 85 degrees as a maximum cut-off for liquid extraction will allow for much increased efficiency in screening further germplasm for high zeaxanthin lines.

Quantification of carotenoid and tocopherol antioxidants in Zea mays.

The observed genetic variability of carotenoids in fresh market sweet corn suggests profound differences in potential health promotion among genotypes and supports the feasibility of developing germplasm with enhanced levels of these antioxidant compounds at dosages that could promote health among the consuming public.

Increase in nutritionally important sweet corn kernel carotenoids following Mesotrione and atrazine applications.

It appears that mesotrione applications resulted in greater pools of kernel carotenoids once the sweet corn genotypes expressing moderate injury overcame the initial herbicidal photo-oxidative stress.

Biologic mechanisms of the protective role of lutein and zeaxanthin in the eye.

Although increasing the intake of lutein or zeaxanthin might prove to be protective against the development of age-related macular degeneration, a causative relationship has yet to be experimentally demonstrated.

Lutein and zeaxanthin dietary supplements raise macular pigment density and serum concentrations of these carotenoids in humans.

It remains to be demonstrated whether lutein or zeaxanthin dietary supplements reduce the incidence of AMD.

Natural Genetic Variation in Lycopene Epsilon Cyclase Tapped for Maize Biofortification

It is shown that variation at the lycopene epsilon cyclase (lcyE) locus alters flux down α-carotene versus β-Carotene branches of the carotenoid pathway, which will enable developing-country breeders to more effectively produce maize grain with higher provitamin A levels.

Lutein + zeaxanthin and omega-3 fatty acids for age-related macular degeneration: the Age-Related Eye Disease Study 2 (AREDS2) randomized clinical trial.

Addition of lutein + zeaxanthin, DHA + EPA, or both to the AREDS formulation in primary analyses did not reduce risk of progression to advanced AMD, but because of potential increased incidence of lung cancer in former smokers, luteIn + zexanthin could be an appropriate carotenoid substitute in the ARedS formulation.

Analysis of xanthophylls in corn by HPLC.

An HPLC method was developed using the C-30 carotenoid column to separate and identify the major xanthophylls in corn (lutein, zeaxanthin, and beta-cryptoxanthin). A photodiode array detector and a
