Biology, Conservation and Sustainable Development of Sturgeons
Sturgeons are considered “living fossils”, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical...
Satellite DNAs in Physiology and Evolution
This book gives a comprehensive overview of the unique roles that non-coding repetitive elements such as satellite DNAs play in different physiological and evolutionary processes. It presents the gene-regulatory aspect of satellite DNAs in different model systems including mammals, insects and plants. In addition, evolutionary aspects of activation of satellite DNAs in terms of transcription and proliferation are highlighted, revealing the role of satellite DNAs in the process of adaptation to changing environment and in the speciation process. Finally, the book discusses satellite DNA activation during pathological transformation and the mechanisms by which they affect disease progression. Namely, some satellite DNAs promote the oncogenic processes by affecting genome epigenetic regulation as well as genome integrity. Readers get a full overview of the latest research on satellite DNA.
Fish Cytogenetics
In the past 20 years, fish cytogenetics has become an essential tool in fields as diverse as systematics and evolution, conservation, aquaculture and more recently, genomics. This book is organized in four sections (systematics and evolution; biodiversity conservation; stock assessment and aquaculture; genomics) covering the major fields of present fish cytogenetic research. The eighteen contributions from thirteen countries which make up this book, provide a comprehensive picture of the ongoing research around the world. Due to the diversified arrays of themes approached, including speciation and evolution, biodiversity and conservation and genomics, the book is addressed not only to specialists in cytogenetics but to all scientists interested in fish biology.
The Lupin Genome
This book on lupin genomics primarily focuses on the narrow-leafed lupin (NLL), and details the genomic resources that have been developed and how they are currently being used to help advance both fundamental and applied research on NLL in areas ranging from its domestication to plant–microbe interactions and syntenic relationships between NLL and other legume crops. It also reports on genomic efforts being pursued with regard to other lupin crops. Lupins are important ecological ‘engineers’: they can colonise and thrive in low-nutrient soils due to their ability to fix atmospheric nitrogen in symbiosis with bacteria and efficiently take up phosphorous. Recently, lupins have attracted...
Progress in Botany 69
With one volume published each year, this series keeps scientists and students current with the latest developments and results in all areas of the plant sciences. This present volume includes insightful reviews covering genetics, cell biology, physiology, comparative morphology, systematics, ecology, and vegetation science.
Evolution, Composition and Regulation of Supernumerary B Chromosomes
Supernumerary B chromosomes (Bs) are dispensable genetic elements found in thousands of species of plants and animals, and some fungi. Since their discovery more than a century ago, they have been a source of puzzlement, as they only occur in some members of a population and are absent from others. When they do occur, they are often harmful, and in the absence of “selfishness”, based on mechanisms of mitotic and meiotic drive, there appears to be no obvious reason for their existence. Cytogeneticists have long wrestled with questions about the biological existence of these enigmatic elements, including their lack of any adaptive properties, apparent absence of functional genes, their origin, sequence organization, and co-evolution as nuclear parasites. Emerging new technologies are now enabling researchers to step up a gear, to look enthusiastically beyond the previous limits of the horizon, and to uncover the secrets of these “silent” chromosomes. This book provides a comprehensive guide to theoretical advancements in the field of B chromosome research in both animal and plant systems.
Fish Diseases and Disorders
Written by experts actively working in the area, this book provides a review of the major diseases of fish caused by protozoan and metazoan parasites. The new edition has been thoroughly updated since publication of the first edition in 1995. It covers recent advances in the understanding of fish diseases including the improvement of diagnostic techniques and understanding of phylogenetic relationships stemming from the application of molecular techniques. The book also contains more detailed information on pathogens that cause amoebiasis.
Genetics and Genomics of Papaya
This book reviews various aspects of papaya genomics, including existing genetic and genomic resources, recent progress on structural and functional genomics, and their applications in papaya improvement. Organized into four sections, the volume explores the origin and domestication of papaya, classic genetics and breeding, recent progress on molecular genetics, and current and future applications of genomic resources for papaya improvement. Bolstered by contributions from authorities in the field, Genetics and Genomics of Papaya is a valuable resource that provides the most up to date information for papaya researchers and plant biologists.
Mechanisms Driving Karyotype Evolution and Genomic Architecture
Understanding of the origin of species and their adaptability to new environments is one of the main questions in biology. This is fueled by the ongoing debate on species concepts and facilitated by the availability of an unprecedented large number of genomic resources. Genomes are organized into chromosomes, where significant variations in number and morphology are observed among species due to large-scale structural variants such as inversions, translocations, fusions, and fissions. This genomic reshuffling provides, in the long term, new chromosomal forms on which natural selection can act upon, contributing to the origin of biodiversity. This book contains mainly articles, reviews, and an opinion piece that explore numerous aspects of genome plasticity among taxa that will help in understanding the dynamics of genome composition, the evolutionary relationships between species and, in the long run, speciation.
