Rice Biofortification

First Published in 2010. Routledge is an imprint of Taylor & Francis, an informa company.

Biofortification - the enrichment of staple food crops with essential micronutrients - has been heralded as a uniquely sustainable solution to the problem of micronutrient deficiency or 'hidden hunger'. Considerable attention and resources are being directed towards the biofortification of rice - the world's most important food crop. Through an in-depth analysis of international rice biofortification efforts across the US, Philippines and China, this book provides an important critique of such goal-oriented, top-down approaches. These approaches, the author argues, exemplify a model of global, 'public goods' science that is emerging within complex, international research networks. It provides vital lessons for those researching and making decisions about science and research policy, showing that if this model becomes entrenched, it is likely to channel resources towards the search for 'silver bullet' solutions at the expense of more incremental approaches that respond to locality, diversity and the complex and uncertain interactions between people and their environments. The author proposes a series of key changes to institutions and practices that might allow more context-responsive alternatives to emerge. These issues are particularly important now as increasing concerns over food security are leading donors and policy makers to commit to ambitious visions of 'impact at scale' - visions which may never become a reality and may preclude more effective pathways from being pursued.

The demand for increased food production needs to be met from ever reducing resources of land, water and other environmental constraints. Rice remains the staple food source for a majority of the global populations, but especially in Asia where ninety percent of rice is grown and consumed. Climate change continues to impose abiotic and biotic stresses that curtail rice quality and yields. Researchers have been challenged to provide innovative solutions to maintain, or even increase, rice production. Amongst them, the ‘green super rice’ breeding strategy has been successful for leading the development and release of multiple abiotic and biotic stress tolerant rice varieties. Recent advances in plant molecular biology and biotechnologies have led to the identification of stress responsive genes and signaling pathways, which open up new paradigms to augment rice productivity. Accordingly, transcription factors, protein kinases and enzymes for generating protective metabolites and proteins all contribute to an intricate network of events that guard and maintain cellular integrity. In addition, various quantitative trait loci associated with elevated stress tolerance have been cloned, resulting in the detection of novel genes for biotic and abiotic stress resistance. Mechanistic understanding of the genetic basis of traits, such as N and P use, is allowing rice researchers to engineer nutrient-efficient rice varieties, which would result in higher yields with lower inputs. Likewise, the research in micronutrients biosynthesis opens doors to genetic engineering of metabolic pathways to enhance micronutrients production. With third generation sequencing techniques on the horizon, exciting progress can be expected to vastly improve molecular markers for gene-trait associations forecast with increasing accuracy. This book emphasizes on the areas of rice science that attempt to overcome the foremost limitations in rice production. Our intention is to highlight research advances in the fields of physiology, molecular breeding and genetics, with a special focus on increasing productivity, improving biotic and abiotic stress tolerance and nutritional quality of rice.

Rice is a staple crop in many coastal and non-coastal areas of the globe and requires a large production area. With the increasing trends in population , it is pivotal to increase the production of this important crop for sustainability. The introduction of high-yielding rice cultivars through molecular breeding is one of the possibilities that can ensure sustainability. Additionally, development of new biotic and abiotic stress-resistant cultivars with higher nutritional value can revolutionize the rice industry.

Biofortification is a widely accepted cost-effective agricultural strategy to improve the nutrient deficiency in populations. It is especially useful in low income and developing nations. Strategies for biofortification employ crop breeding, targeted genetic alteration, and agronomy, show promise for addressing multiple forms of human malnutrition. To increase the bioavailability of food nutrients, biofortification efforts must focus on improving the nutrient content of food and decreasing anti-nutrients. This book covers the basics of biofortification, international efforts, challenges, opportunities, and the use of the latest omics technologies in addition to classical approaches. It covers the most studied micronutrients, vitamin biofortification, and the new topics in dietary fibers, starch quality, and phenolics. It uniquely covers the antinutrients like phytic acid, ODAP, and Glucosinolates. It also reviews food bioavailability, scientific research, and meta-analyses to assess the health-promoting efficacy of different nutrients. The book attempts to cover all bases, from decision considerations to prospects, as well as biofortification of nutrients, antinutrient reduction, and the use of latest technology to aid in the nutritional enhancement of virtually all recorded food crops.

This book aims to provide an overview of the challenges and available technologies to improve rice and provide a response to the challenge posed by increasing world population and the resultant food shortages. Nutritional aspects of rice products and omics and the molecular technologies currently being used are covered in depth. As a staple food for over 50% of the world ́s population, an estimated 9 billion people will need to be fed by 2050, and healthy and uncontaminated foods need to reach consumers in developed and developing countries.This makes quality beyond productivity incredibly important and is one of the overriding themes of this work. The Future of Rice Demand: Quality Beyond Productivity offers researchers a better understanding of the nutritional aspects of rice. Omics technologies applied to cereal grain quality have been scarce in the literature published to date, making this text an excellent single source for researchers in regions where rice is a major crop. The first section of the book focuses on the major aspects of the industrial processing of all rice types. Further sections look at contamination prevention and biofortification, special rice types, and omics and other molecular tools used in the mass production and processing of healthy rice products.

Wheat and Rice in Disease Prevention and Health reviews the wide range of studies focusing on the health benefits and disease prevention associated with the consumption of wheat and rice, the two most widely consumed whole grains. This book provides researchers, clinicians, and students with a comprehensive, definitive, and up-to-date compendium on the diverse basic and translational aspects of whole grain consumption and its protective effects across human health and disease. It serves as both a resource for current researchers as well as a guide to assist those in related disciplines to enter the realm of whole grain and nutrition research. Overall, studies have shown that a decrease in the amount of whole grains in the modern diet is related to a corresponding increase in health problems that are attributed to this all-too-common dietary imbalance. The resulting health issues associated with an over-processed diet, which provides inadequate levels of nutrients from whole grains, may include obesity, diabetes, high blood lipids, chronic inflammatory states, and an excess of oxidative stress. Strength and endurance may also suffer as a result of these nutrient deficiencies, followed by declines in energy and immunity. Saves researchers and clinicians time in quickly accessing the latest details on a broad range of nutritional and epidemiological issues Provides a common language for nutritionists, nutrition researchers, epidemiologists, and dietitians to discuss how the action of wheat and rice protect against disease and modify human health Preclinical, clinical, and population studies help nutritionists, dieticians, and clinicians map out key areas for research and further clinical recommendations
