Available in PDF, EPUB and Kindle. Book excerpt: Carotenoids (provitamin A) and tocochromanols (vitamin E) are lipid-soluble isoprenoids with antioxidant and essential nutrient functions in human and animal systems. Vitamin A deficiency and age-related macular degeneration are highly prevalent and result from insufficient dietary intake of certain carotenoids. Improvement of the levels and balance of these nutrients in maize grain through breeding, i.e. biofortification, has been proposed as a cost-effective solution to ameliorate deficiency. To do so requires a more comprehensive dissection of the loci governing natural variation of carotenoid and tocochromanol traits, with high statistical power and mapping resolution, in grain of maize and other major cereal crops. Our group conducted joint linkage-genome wide association studies (JL-GWAS) and RNA-seq expression analyses for these traits in the 5000-line US maize nested association mapping (NAM) population. The majority of identified QTL were found to be underpinned by genes with a priori roles in carotenoid and/or tocochromanol synthesis and retention, including prenyl group synthesis. Surprisingly, two homologs encoding a chlorophyll biosynthetic enzyme explained the majority of variation for saturated tocochromanols (i.e., tocopherols). While maize grain is non-photosynthetic, small levels of chlorophyll were found to be present in embryo, suggestive along with other evidence of a chlorophyll biosynthetic cycle providing phytol for tocopherol synthesis. Overall, more than half of the identified QTL were eQTL, and most also had highly correlated QTL allelic effect estimates across traits, suggesting that pleiotropy within these biosynthetic pathways is largely regulated at the expression level. A number of significant pairwise epistatic interactions were additionally detected, particularly for carotenoids, between identified genes within and outside of the biosynthetic pathway. Finally, our group is analyzing carotenoid and tocochromanol nutritional profiles and agronomic performance of 350 tropically adapted maize hybrids evaluated under combined drought and heat stress in conjunction with the International Maize and Wheat Improvement Center (CIMMYT), Harare, Zimbabwe. In addition to analyzing genetics and genomics within a key target environment for orange, provitamin A-dense (i.e. biofortified) orange maize, candidate lines are being identified and incorporated into the HarvestPlus breeding program to produce nutritious, climate-resilient varieties for the rainfed production areas of southern Africa.

This book was released on 2000-08-27 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.

Download or read book Genetic Dissection of Carotenoid Concentration and Compositional Traits in Maize Grain written by Catherine Kandianis and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Carotenoid compounds are derivatives of a well described secondary metabolic pathway in plants, participating in a diverse array of physiological functions, and are nutritionally valued vitamin precursors in the human diet. With the goal of enhancing the quantity (concentration) and quality (composition) of carotenoids in consumable plant tissues such as grain, breeding approaches have sampled from the extensive phenotypic variation that exists for these traits among maize inbreds. The predominant carotenoids in maize grain include lutein and zeaxanthin, which are collectively called di-hydroxy xanthophyll carotenoids, as well as alpha-carotene, beta-carotene and beta-cryptoxanthin, which are proVitamin A carotenoids. While phenotypic sampling and recombination across diverse maize germplasm has been successful, response to phenotypic selection has not been large enough to satisfy target nutritional levels. Greater phenotypic gain may be more predictably achieved if: 1) the genetic network regulating biological functions which contribute to carotenoid accumulation was better understood; and 2) the relative effect of the genetic loci controlling this quantitative trait was known, especially in varying genetic backgrounds. To this end, an investigation of the genetic basis for variation in carotenoid concentration and composition was performed in the studies presented here. Two QTL analyses revealed gene networks likely involved in carotenoid biosynthesis, conversion, and degradation as the primary drivers of variation in carotenoid concentration and composition. Investigation of one QTL hotspot on maize chromosome 9, observed to account for significant phenotypic variation in almost all carotenoid intermediates, revealed an allelic series associated with a large reduction in the major carotenoid intermediates of maize grain. This QTL, encoding carotenoid cleavage dioxygenase 1 (ccd1), showed a substrate preference for all measured carotenoids except beta-carotene. We further evaluated allelic variation affecting carotenoid composition focusing on two genes within the carotenoid biosynthesis pathway at lycopene epsilon cyclase (lcye) and beta-carotene hydroxylase (crtRB1). Variation at each of these genes was found to significantly affect carotenoid ratios or intermediates hypothesized to change through predicted substrate-enzyme interactions. Several other traits including total carotenoid concentration, were unexpectedly affected. Using allele-specific marker assisted selection at lcye and crtRB1 in synthetic populations developed for high total carotenoid content lead to a 3.95-11.33-fold improvement in beta-carotene and 1.45-3.22-fold improvement in proVitamin A for the favorable genotypes. The combined information from these studies highlights new genetic targets for further improvement of carotenoid concentration and composition, and provides guidelines for the selection and recombination of desirable genetic variation in breeding germplasm.

Download or read book Biofortification of Staple Crops written by Shiv Kumar and published by Springer Nature. This book was released on 2022-03-09 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book brings together comprehensive information on various aspects of the biofortification of staple crops. It addresses the present status of food and nutritional security and highlights the importance of micronutrients in human health, a historical account of biofortification, current approaches and challenges, crop-specific biofortification efforts and various breeding approaches, including conventional, and genomics enabled improvement. It also explains the efficacy of biofortification, bioavailability, and future thrust. It is an inclusive source of information on different aspects of micronutrients in crops of global importance. Malnutrition is a serious global issue, with millions of people being undernourished, several suffering from micronutrient deficiencies, and the adult population struggling with obesity. Despite significant economic progress, South Asia and Sub-Saharan Africa are still home to an undernourished population. Nutrition-related health problems are related to hidden hunger and are widespread in the developing world. Women and preschool children are more vulnerable. Even though global food production has increased manifolds, estimates indicate that over 60% of the world’s population is deficient in essential micronutrients such as iron, zinc, iodine, and selenium, often causing health problems and developmental delays. Linking agricultural production with human nutrition and health is crucial for ensuring nutrition security. Much research has been carried out to assess genetic diversity related to micro-nutrients in staple crops, their bioavailability, and the efficacy of biofortified germplasm. Biofortified varieties developed in different crops through conventional breeding are being up-scaled for reducing the micronutrient deficiencies in other countries. This book is a ready reference for researchers, academicians, extension personnel, policymakers, students, and value chain stakeholders engaged in agriculture, nutrition, and health sectors promoting nutrition-sensitive diets.
