Underutilised Crop Genomes


Book Description

This book highlights the uses for underutilized crops, presenting the state-of-the-art in terms of genome sequencing for over 30 crops, previously understudied and under-researched. In a changing climate and with significant pressure on the land, it is the ideal time to be discussing novel crops, with significant biotic and abiotic tolerances and/or rich nutrient profiles for consumers. Previously, the only species with sequenced genomes were high-profile internationally recognized crops, but in the current era genomes are being sequenced for dozens of crops, including those previously classified as underutilized, now being investigated. This book covers food crops, from fruits to tubers, and from grasses to legumes, as well as crops with non-food applications. Some of these crops have draft genomes, and others have polished genomes with extensive resequencing panels. Each chapter tells the story of an individual crop or crop group, written by experts, focusing on the genome data available, revealing more about crop domestication and genetic variation, and the current and future prospects given that this data is now becoming available. It also highlights how even small sequencing projects can provide draft genome sequences suitable for gene discovery, comparative genomics, and identification of molecular markers for understanding these crops further.




Global Perspectives on Underutilized Crops


Book Description

Increase in world population, extreme weather conditions, decrease in fresh water supplies, and changes of dietary habits are major issues that affect global food security. We are expected to face the challenges of land use by 2050 because population will reach 9 billion while agricultural productivity losses are expected due to overuse of lands. How can we feed the next generations in a manner that respects our finite natural resources? Managing our resources in a sustainable way have only begun for selected crops. Much remains to be done to increase food yield. Cropping practices capable of sustainable production need to be elaborated, especially in fragile ecosystems. Typical applications will include the improvement and use of genetic resources; crop management and diversification; diffusion of improved varieties; development of cropping systems; sustainable cropping systems for areas prone to environmental degradation; use of agro-ecological data for crop production forecasting; and networks for regional coordination, and data exchange. The impetus behind this book is to bring attention to a cropping system that bears direct relevance to sustainable agriculture and food security. “Underutilized” crops are found in numerous agricultural ecosystems and often survive mainly in marginal areas. It is timely to review their status because, in recent decades, scientific and economic interests have emerged which focus on lesser-known cultivated species. Underutilized crops have a great potential to alleviate hunger directly, through increasing food production in challenging environments where major crops are severely limited. “Global Perspectives on Underutilized Crops” is therefore topical and highlights the unmet agricultural challenges that we face today. This book is an important resource for students and researchers of crop science and agricultural policy makers.




Crop Improvement


Book Description

The book covers the latest development in the biosciences field covering key topics in crop improvement including ‘omic approaches to improving sustainable crop production, advancement in marker technology, strategies in genetic manipulation, crop quality and sustainability and plant microbe interaction detailing on proven technologies to address critical issue for agricultural sustainability which are beneficial for researchers and students. The book also includes aspects of preserving crops after harvest as this is a key factor in promoting sustainable crop quality in terms of addressing waste, choosing the appropriate packaging and moving crops through the food and industrial supply chain. An important strategy to overcome the challenges in providing food for the world population in a sustainable manner is through concerted efforts by crop scientists to embrace new technologies in increasing yield, quality and improving food safety while minimizing adverse environmental impact of the agricultural activities. Most of the proven molecular and genetic technologies in crop science have been tested and verified in model plants such as Arabidopsis and tomato. The technologies, when deployed on various plant species of importance for human nutrition and industrial applications, including cereals, vegetables, fruits, herbs, fibre and oil crops, face many challenges, not only due to their longer life cycle but many other physiological and environmental factors affecting yield and quality of plant products. Furthermore, major impacts on crop production due to catastrophic diseases and global climate change needs urgent and innovative solutions. Therefore a systematic approach, employing various leading-edge technologies that enable the functional elucidation of key pathway genes via ‘omics tools, genome wide association with desired phenotypes and development of cost effective and practicable molecular tools for selection, is vital. The International Conference on Crop Improvement was held to address these and other pressing issues. This volume summarizes the keynote presentations from the meeting and highlights addition discussions that are critical to crop improvement in a challenging time.




Neglected and Underutilized Crop Species for Sustainable Food and Nutritional Security: Prospects and Hidden Potential


Book Description

Global demand for food is rising as a result of increases in the global population as well as dietary changes. Furthermore, climate change exerts additional pressure on the food supply, adversely affecting sustainable food production. Increased temperatures and drought stresses coupled with the migration of pests limit crop yields and affect their nutritional quality. Many staple crops are unable to adapt to these changing climatic conditions. To achieve the Sustainable Development Goals of the United Nation to end hunger and promote good health and well-being, concerted efforts need to be made to enhance food production while mitigating the effects of climate change through the promotion of climate-smart agricultural practices and the utilization of neglected and underutilized crop species. These species can be highly nutritious and well-adapted to different agroecologies and climatic conditions, meaning that they offer the possibility of improving food and nutritional security.




Genomic Designing for Abiotic Stress Resistant Vegetable Crops


Book Description

This book presents deliberations on molecular and genomic mechanisms underlying the interactions of crop plants to the abiotic stresses caused by heat, cold, drought, flooding, submergence, salinity, acidity, etc., important to develop resistant crop varieties. Knowledge on the advanced genetic and genomic crop improvement strategies including molecular breeding, transgenics, genomic-assisted breeding, and the recently emerging genome editing for developing resistant varieties in vegetable crops is imperative for addressing FHNEE (food, health, nutrition, energy, and environment) security. Whole genome sequencing of these crops followed by genotyping-by-sequencing has provided precise information regarding the genes conferring resistance useful for gene discovery, allele mining, and shuttle breeding which in turn opened up the scope for 'designing' crop genomes with resistance to abiotic stresses. The nine chapters each dedicated to a vegetable crop or crop group in this volume elucidate on different types of abiotic stresses and their effects on and interaction with the crop; enumerate on the available genetic diversity with regard to abiotic stress resistance among available cultivars; illuminate on the potential gene pools for utilization in interspecific gene transfer; present brief on classical genetics of stress resistance and traditional breeding for transferring them to their cultivated counterparts; depict the success stories of genetic engineering for developing abiotic stress-resistant crop varieties; discuss on molecular mapping of genes and QTLs underlying stress resistance and their marker-assisted introgression into elite varieties; enunciate on different genomics-aided techniques including genomic selection, allele mining, gene discovery, and gene pyramiding for developing adaptive crop varieties with higher quantity and quality of yields, and also elaborate some case studies on genome editing focusing on specific genes for generating abiotic stress-resistant crops




Bioactive Compounds in the Storage Organs of Plants


Book Description

Zusammenfassung: This book offers a comprehensive and authoritative review of bioactive substances found in plant underground stems, roots, rhizomes, corms, and tubers from all around the world. Tubers and starchy roots are plants that store edible starch content in underground stems, roots, rhizomes, corms, and tubers. They are a key source for both human and animal consumption and are rich in carbohydrates. They are widely used as industrial crops as well. Phytochemicals found in tubers and roots, such as phenolics, terpenoids, and alkaloids, have anti-inflammatory, anti-cancer, hypoglycemic, hypocholesterolemic, and antibacterial properties. Except for common potatoes, sweet potatoes, and cassava, the nutritional and health benefits of many tuberous crops have not yet been adequately investigated. This book sheds new insights into these topics by addressing several plant metabolites found in storage organs, which can be seen as scientifically neglected even though they have a high economic relevance as food and pharmaceutical sources. Divided into 6 parts, this book discusses how bioactive chemicals found in plant storage organs are synthesized and how their bioactive principles are specifically expressed in underground stems, roots, rhizomes, corms, and tubers. Additionally, each chapter includes background information on the plant, its parts, its nutritional makeup, chemical components, and biological functions. Given its breadth, the book appeals to a wide readership, from scholars through graduate and post-graduate students to professionals in the industry
