A Foundation for Provitamin A Biofortification of Maize: Genome-Wide Association and Genomic Prediction Models of Carotenoid Levels
Efforts are underway for development of crops with improved levels of provitamin A carotenoids to help combat dietary vitamin A deficiency. As a global staple crop with considerable variation in kernel carotenoid composition, maize (Zea mays L.) could have a widespread impact. We performed a genome-wide association study (GWAS) of quantified seed carotenoids across a panel of maize inbreds rang...
متن کاملMetabolite sorting of a germplasm collection reveals the hydroxylase3 locus as a new target for maize provitamin A biofortification.
Vitamin A deficiency, a global health burden, can be alleviated through provitamin A carotenoid biofortification of major crop staples such as maize (Zea mays) and other grasses in the Poaceae. If regulation of carotenoid biosynthesis was better understood, enhancement could be controlled by limiting beta-carotene hydroxylation to compounds with lower or no nonprovitamin A activity. Natural mai...
متن کاملRetention of Provitamin A Carotenoids in Staple Crops Targeted for Biofortification in Africa: Cassava, Maize and Sweet Potato
HarvestPlus, part of the Consultative Group on Internation Agriculture research (CGIAR) Program on Agriculture for Nutrition and Health (A4NH) uses conventional plant breeding techniques to develop staple food crops that are rich in micronutrients, a food-based approach to reduce micronutrient malnutrition known as biofortification. The nutritional breeding targets are established based on the ...
متن کاملToxic Effects of Heavy Metals on Plant Growth and Metal Accumulation in Maize (Zea maysL.)
Background: A pot experiment was conducted to determine the toxic effects of some heavy metals on the plant growth and seed yield of maize (Zea mays L.). Materials and Metheds: Heavy metals Mn, Pb, Cd, Cr and Co individually and in combinations were added as chloride salts in solutions to the pots before sowing. The test plants for were harvested after 80 days of germination and evaluated f...
متن کاملGeneration of transgenic maize with enhanced provitamin A content
Vitamin A deficiency (VAD) affects over 250 million people worldwide and is one of the most prevalent nutritional deficiencies in developing countries, resulting in significant socio-economic losses. Provitamin A carotenoids such as beta-carotene, are derived from plant foods and are a major source of vitamin A for the majority of the world's population. Several years of intense research has re...
