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.




Recent Advances in Genetics and Breeding of Major Staple Food Crops


Book Description

To meet the global food demand of an increasing population, food production has to be increased by 60% by 2050. The main production constraints, such as climate change, biotic stresses, abiotic stresses, soil nutrition deficiency problems, problematic soils, etc., have to be addressed on an urgent basis. More than 50% of human calories are from three major cereals: rice, wheat, and maize. The harnessing of genetic diversity by novel allele mining assisted by recent advances in biotechnological and bioinformatics tools will enhance the utilization of the hidden treasures in the gene bank. Technological advances in plant breeding will provide some solutions for the biofortification, stress resistance, yield potential, and quality improvement in staple crops. The elucidation of the genetic, physiological, and molecular basis of useful traits and the improvement of the improved donors containing multiple traits are key activities for variety development. High-throughput genotyping systems assisted by bioinformatics and data science provide efficient and easy tools for geneticists and breeders. Recently, new breeding techniques applied in some food crops have become game-changers in the global food crop market. With this background, we invited 18 eminent researchers working on food crops from across the world to contribute their high-quality original research manuscripts. The research studies covered modern food crop genetics and breeding: plant molecular systems focusing to food crops; plant genetic diversity—QTL and gene identification utilizing high-throughput genotyping systems and their validation; new breeding techniques in food crops—targeted mutagenesis, genome editing, etc.; abiotic and biotic stresses—QTL/gene identification and their molecular physiology; plant nutrition, grain quality improvement, and yield enhancement.
