Even before the publication of Darwin's Origin of Species, the perception of evolutionary change has been a tree-like pattern of diversification - with divergent branches spreading further and further from the trunk. In the only illustration of Darwin's treatise, branches large and small never reconnect. However, it is now evident that this view does not adequately encompass the richness of evolutionary pattern and process. Instead, the evolution of species from microbes to mammals builds like a web that crosses and re-crosses through genetic exchange, even as it grows outward from a point of origin. Some of the avenues for genetic exchange, for example introgression through sexual recombination versus lateral gene transfer mediated by transposable elements, are based on definably different molecular mechanisms. However, even such widely different genetic processes may result in similar effects on adaptations (either new or transferred), genome evolution, population genetics, and the evolutionary/ecological trajectory of organisms. For example, the evolution of novel adaptations (resulting from lateral gene transfer) leading to the flea-borne, deadly, causative agent of plague from a rarely-fatal, orally-transmitted, bacterial species is quite similar to the adaptations accrued from natural hybridization between annual sunflower species resulting in the formation of several new species. Thus, more and more data indicate that evolution has resulted in lineages consisting of mosaics of genes derived from different ancestors. It is therefore becoming increasingly clear that the tree is an inadequate metaphor of evolutionary change. In this book, Arnold promotes the 'web-of-life' metaphoras a more appropriate representation of evolutionary change in all lifeforms.

This book takes a fresh look at the work, thoughts, and life of 1956 Nobel Prize winner William B. Shockley. It reconstructs Shockley's upbringing, his patriotic achievements during World War II, his contribution to semiconductor physics - culminating with the epoch-making invention of the transistor - and his views on the social issues of his time. The author's unparalleled access to Shockley's personal documents provides insight into a colorful, yet controversial, man, and also sheds light on the attitudes of other prominent scientists of that era. Shockley was not only an outstanding scientist in his own right but also a fiercely independent thinker in perpetual search of the truth. His contributions to the field known today as microelectronics are enormous and unmatched. This book explores the critical facets of Shockley's life, replete with never-before-published photos and excerpts from his private correspondence and personal notebooks. The book also delves into Shockley's views on genetics and human intelligence. It tells the story of a man beset by an unrelenting rationality, slandered by the popular media, and ultimately alienated by his peers. It discusses his controversial, although sometimes prescient, ideas regarding human genetics, putting these into the context of modern research findings. Today, William Shockley is perhaps just as enigmatic as his work and accomplishments. The author presents a convincing argument that Shockley still has much to say about the issues of our age, and many of his ideas deserve evaluation in the public forum.
Various "omics" methods have recently revolutionized molecular diagnostics. Next-generation sequencing (NGS) makes it possible to sequence a human genome in just one day. Whole genome sequencing (WGS) greatly improves the ability to investigate the outbreaks of numerous pathogens. Metagenomics helps to analyze the microbiome, which aids greatly in identifying the pathogenesis of infectious diseases. Proteomic-based methods, namely matrix-assisted laser desorption-ionization time of flight mass spectrometry (MALDI-TOF-MS), have a promising role in identifying myctobacteria and fungi, and predicting antimicrobial resistance. While there are numerous scientific publications on "omics" applications for microbiology, there are relatively few books that review this topic from a clinical diagnostics perspective. This book looks at this field from a holistic viewpoint, instead of limiting by type of "omics" technology, in order to cover the body of knowledge needed for practitioners and academics interested in clinical and public health microbiology. Additionally, it addresses the management, economical, regulatory and operational aspects of integrating these technologies into routine diagnostics.

Authoritative and practical, Capturing Chromosome Conformation: Methods and Protocols serves as an ideal guide for researchers working to further understand 3D genome organization.
Ancestral sequence reconstruction is a technique of growing importance in molecular evolutionary biology and comparative genomics. As a powerful tool for testing evolutionary and ecological hypotheses, as well as uncovering the link between sequence and molecular phenotype, there are potential applications in a range of fields. Ancestral Sequence Reconstruction starts with a historical overview of the field, before discussing the potential applications in drug discovery and the pharmaceutical industry. This is followed by a section on computational methodology, which provides a detailed discussion of the available methods for reconstructing ancestral sequences (including their advantages, disadvantages, and potential pitfalls). Purely computational applications of the technique are then covered, including whole proteome reconstruction. Further chapters provide a detailed discussion on taking computationally reconstructed sequences and synthesizing them in the laboratory. The book concludes with a description of the scientific questions where experimental ancestral sequence reconstruction has been utilized to provide insights and inform future research. This research level text provides a first synthesis of the theories, methodologies and applications associated with ancestral sequence recognition, while simultaneously addressing many of the hot topics in the field. It will be of interest and use to both graduate students and researchers in the fields of molecular biology, molecular evolution, and evolutionary bioinformatics.
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 oilseed 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 eight chapters each dedicated to a oilseed crop 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.
The study of molecular events leading to cellular transformation and cancer has progressed considerably during the 1990s. It has become apparent that many genes subject to modification in cancer are, in fact, transcription factors that govern the execution of the genetic programme of the cell. Transcription factors can behave either as oncogenes or as tumor supressor genes. To date only a very limited number of transcription factors have been associated with cancer. This volume gives molecular information on several oncogenes, tumor suppressor genes or chromosomal translocations. Each chapter contains a description of the structure of such transcription factors, the nature of target genes, the regulation of their activities and an explaination of how they can deregulate cell growth and differentiation. This book should be suitable for the specialist scientist and the advanced student
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 considerable interest, not only because of their value for sustainable farming as a break crop, but also as a potential 'super food' for fighting major health issues in connection with diabetes and obesity. Narrow-leafed lupin is the main grain legume crop, grown primarily in Australia, and was therefore selected for the development of a reference lupin genome and associated genomic resources. Its genome has recently been sequenced with a focus on the gene-rich space, which has advanced the development of new breeding tools for the improvement of NLL and related lupin crops.
This volume explains the recent findings on the mutualistic plant-microbe interactions and how they can be utilized for sustainable agriculture practices including land reclamation. The book covers mainly plant growth promoting microorganisms (PGPMs) including both the symbiotic bacteria and fungi and their role in mobilization of nutrients, providing protection to the crops from phytopathogens and abiotic stresses. PGPMs play important roles in survival and health of the plant. These useful microorganisms provide plants with nutrients, protect them from pathogens and help them combat abiotic stresses. It is important that these mutualistic interactions between plant and soil microbes are well understood so as to develop reliable products in the form of biostimulants and biopesticides, as well as managing biotic and abiotic stresses in crops. Apart from enhancing crop productivity plant-microbe interactions can also perform activities such as reclamation of degraded lands, degradation of pollutants and remediation of saline or marginal lands. This book is of interest to teachers, researchers, plant scientists and microbiologists. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, microbiology, biotechnology, ecology, soil science and environmental sciences.

This book explores the answers to fundamental questions about the human mind and human behaviour with the help of two ancient texts. The first is Oedipus Rex (Oedipus Tyrannus) by Sophocles, written in the 5th century BCE. The second is human DNA, with its origins around 4 billion years ago, and continuously revised by chance and evolution. With Sophocles as a guide, the authors take a journey into the Genomic era, an age marked by ever-expanding insights into the human genome. Over the course of this journey, the book explores themes of free will, fate, and chance; prediction, misinterpretation, and the burden that comes with knowledge of the future; self-fulfilling and self-defeating prophecies; the forces that contribute to similarities and differences among people; roots and lineage; and the judgement of oneself and others. Using Oedipus Rex as its lens, this novel work provides an engaging overview of behavioural genetics that demonstrates its relevance across the humanities and the social and life sciences. It will appeal in particular to students and scholars of genetics, education, psychology, sociology, and law.

This detailed volume presents a comprehensive bioinformatic and experimental toolbox for prioritizing, annotating, and functionally analyzing long non-coding RNAs (lncRNAs). Playing a vital role in diverse biological progresses and human disease, lncRNAs have proven to be a challenging subject of study due to our limited understanding of their sequence-function relationships, lack of complete genetic annotation, and the unavailability of systems required to define their functional importance and molecular mechanisms, all of which this book seeks to address. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Functional Analysis of Long Non-Coding RNAs: Methods and Protocols provides a timely and convenient resource to facilitate the identification and characterization of disease-associated human lncRNAs, which aims to shed light on their role in biology and pathophysiology and ultimately lead toward novel therapeutic approaches targeting lncRNAs for the amelioration of human diseases.
This book summarizes early pioneering achievements in the field of human neural stem cell (hNSC) research and combines them with the latest advances in stem cell technology, including reprogramming and gene editing. The powerful potential of hNSC to generate and repair the developing and adult CNS has been confirmed by numerous experimental in vitro and in vivo studies. The book presents methods for hNSC derivation and discusses the mechanisms underlying NSC in vitro fate decisions and their in vivo therapeutic mode of action. The long-standing dogma that the human central nervous system (CNS) lacks the ability to regenerate was refuted at the end of the 20th century, when evidence of the presence of neurogenic zones in the adult human brain was found. These neurogenic zones are home to human neural stem cells (hNSCs), which are capable of self-renewing and differentiating into neurons, astrocytes and oligodendrocytes. NSCs isolated from human CNS have a number of clinical advantages, especially the innate potential to differentiate into functional neural cells. Nevertheless, their full clinical exploitation has been hindered by limited access to the tissue and low expansion potential. The search for an alternative to CNS sources of autologous, therapeutically competent hNSCs was the driving force for the many studies proving the in vitro plasticity of different somatic stem cells to generate NSCs and their functional progeny. Now the era of induced pluripotent stem cells has opened entirely new opportunities to achieve research and therapeutic goals with the aid of hNSCs.
Sex ratio, the proportion of a progeny that is female, is an extremely important fitness trait. It is particularly interesting in relation to haplodiploidy, a variety of parthenogenesis in which organisms reproduce without the benefit of fertilization. This study arrives at conclusions drawn from new empirical studies: that biased sex ratios are characteristic of haplodiploid species; that these species are characteristically colonizing species with genetics suited both to spatially and temporally unpredictable environments; that manipulation of haplodiploid biological control agents, or pests that are to be controlled, depends on understanding the determinants of sex ratio; and that because evolutionary theory predicts that haplodiploids have the capacity to evolve faster than diploid organisms, haplodiploid species are the organisms of choice in biological control strategies.

Biotic stresses cause yield loss of 31-42% in crops in addition to 6-20% during post-harvest stage. Understanding interaction of crop plants to the biotic stresses caused by insects, bacteria, fungi, viruses, and oomycetes, etc. is 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 pulse crops is imperative for addressing FPNEE (food, health, nutrition. energy and environment) security. Whole genome sequencing of these crops followed by genotyping-by-sequencing have facilitated precise information about 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 biotic stresses. The nine chapters each dedicated to a pulse crop in this volume elucidate on different types of biotic stress agents and their effects on and interaction with the crop plants; enumerate on the available genetic diversity with regard to biotic stress resistance among available cultivars; illuminate on the potential gene pools for utilization in interspecific gene transfer; present brief on the classical genetics of stress resistance and traditional breeding for transferring them to their cultivated counterparts; depict the success stories of genetic engineering for developing biotic stress resistant varieties; discuss on molecular mapping of genes and QTLs underlying biotic stress resistance and their marker-assisted introgression into elite varieties; enunciate on different emerging genomics-aided techniques including genomic selection, allele mining, gene discovery and gene pyramiding for developing resistant crop varieties with higher quantity and quality of yields; and also elaborate some case studies on genome editing focusing on specific genes for generating disease and insect resistant crops. |
