Bananas are a staple food for over 500 million people and are also an important cash crop. Fusarium wilt, caused by the fungus Fusarium oxysporum f.sp. cubense, is one of the most destructive diseases of banana globally. Since the 1990s, an aggressive variant of this fungus, called Tropical Race 4 (TR4), severely affected banana plantations in Southeast Asia from where it spread to other continents, including Latin America, where the global banana export market is primarily centred. TR4 is a soil borne pathogen making the disease difficult to contain. The Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture implemented a Coordinated Research Project (CRP) ‘Efficient Screenin...
This open access book presents simple, robust pre-field screening protocols that allow plant breeders to screen for enhanced tolerance to heat stress in rice. Two critical heat-sensitive stages in the lifecycle of the rice crop are targeted – the seedling and flowering stages – with screening based on simple phenotypic responses. The protocols are based on the use of a hydroponics system and/or pot experiments in a glasshouse in combination with a controlled growth chamber where the heat stress treatment is applied. The protocols are designed to be effective, simple, reproducible and user-friendly. The protocols will enable plant breeders to effectively reduce the number of plants from a few thousands to less than 100 candidate individual mutants or lines in a greenhouse/growth chamber, which can then be used for further testing and validation in the field conditions. The methods can also be used to classify rice genotypes according to their heat tolerance characteristics. Thus, different types of heat stress tolerance mechanisms can be identified, presenting opportunities for pyramiding different (mutant) sources of heat stress tolerance.
This open-access book provides a comprehensive overview of current methodologies for improving resistance to leaf rust in coffee, one of the world's most important cash crops and beverages. Coffea arabica L. (Arabica) accounts for about 60% of the world's coffee production. Coffee leaf rust (CLR), caused by the fungus Hemileia vastatrix is the major disease affecting Arabica coffee resulting in losses of over $1 billion annually. The geographical distribution of CLR is expanding due to climate change. Moreover, the genetic improvement of Arabica coffee is constrained due to its very narrow genetic base. This protocol book introduces essential concepts of mutation breeding as an efficient too...

Abstract: This book presents contemporary information on mutagenesis in plants and its applications in plant breeding and research. The topics are classified into sections focusing on the concepts, historical development and genetic basis of plant mutation breeding (chapters 1-6); mutagens and induced mutagenesis (chapters 7-13); mutation induction and mutant development (chapters 14-23); mutation breeding (chapters 24-34); or mutations in functional genomics (chapters 35-41). This book is an essential reference for those who are conducting research on mutagenesis as an approach to improving or modifying a trait, or achieving basic understanding of a pathway for a trait --.
When one is privileged to participate long enough in a professional capacity, certain trends may be observed in the dynamics of how challenges are met or how problems are solved. Agricultural research is no exception in view of how the plant sciences have moved forward in the past 30 years. For example, the once grand but now nearly forgotten art of whole plant physiology has given way almost completely to the more sophisticated realm of molecular biology. What once was the American Society of Plant Physiologists’ is now the American Society of Plant Molecular Biology; a democratic decision to indemnify efforts to go beyond the limits of the classical science and actually begin to understa...
"International authors review achievements, new developments, trends and challenges in the field of plant mutation breeding, across the scientific community and the private sector. Chapters highlight specific challenges, such as emerging transboundary threats to crop production, and assess the overall importance of mutation breeding to food security"--
Nadia Boulanger - composer, critic, impresario and the most famous composition teacher of the twentieth century - was also a performer of international repute. Her concerts and recordings with her vocal ensemble introduced audiences on both sides of the Atlantic to unfamiliar historical works and new compositions. This book considers how gender shaped the possibilities that marked Boulanger's performing career, tracing her meteoric rise as a conductor in the 1930s to origins in the classroom and the salon. Brooks investigates Boulanger's promotion of structurally motivated performance styles, showing how her ideas on performance of historical repertory and new music relate to her teaching of music analysis and music history. The book explores the way in which Boulanger's musical practice relied upon her understanding of the historically transcendent masterwork, in which musical form and meaning are ideally joined, and shows how her ideas relate to broader currents in French aesthetics and culture.
This publication contains the results of an FAO/IAEA Co-ordinated Research Project (CRP) on Radiation Induced Mutations and Other Advanced Technologies for the Production of Crop Mutants Suitable for Environmentally Sustainable Agriculture. Induced mutation techniques and other biotechnological approaches are major tools for creating variability and selection of stress-resistant or tolerant genotypes. Additionally, scientists have become intensely interested in mutations as a means to widen and deepen our understanding of genome structure and gene function.
