Thirty years ago we knew that retrotransposons made up at least half of our genomes, but little about their role in biology. The human genome has since been sequenced and the position of all retrotransposons in the reference sequence has been determined. However, as of today, the function of retrotransposons still remains elusive. We know much more about the diseases associated with their movement and the host defenses we all have against them.This volume explores an array of diseases in humans associated with L1 retrotransposon movement within the human genome, including some cancers such as colon cancer and neuropsychiatric disorders such as schizophrenia.The chapters explore the diversity of retrotransposons, their different biological mechanisms, the role of L1 in their movement, and their contribution to human diseases. This book posits that somatic events caused by retrotransposons have implications for mosaicism and are often associated with cancers. Germline events are common, occur quite early in development, and are a cause of single gene diseases. All in all, the authors implicate L1 retrotransposons as major sources of human diversity and advocate for their continued study.

This book is about mobile genes—the transfer of DNA between unrelated cells. It discusses the machinery of gene transfer and its wide-ranging biological and health consequences. Mobile DNA makes possible the development of antibiotic resistance in microbes, the conversion of harmless to pathogenic bacteria, and the triggering of cancerous growth in cells. It also contributes to human evolution. This well-illustrated volume contains an up-to-date account of a topic now seen as increasingly important, and will be invaluable for both working scientists and as a textbook for advanced courses.

Annotation What we now know about mobile DNA--and the substantial roles it plays in humans, animals, and plants. & bull; & bull;Mobile DNA accounts for more than half of our genome: This book explains the important role it plays in shaping evolutionary change. & bull;A rich, thorough, and accessible introduction for all serious students, practitioners, and researchers in human and medical genetics, molecular biology, or evolutionary biology. & bull;By one of the field's leading researchers, Dr. Haig Kazazian. This book thoroughly reviews our current scientific understanding of the significant role that mobile genetic elements play in the evolution and function of genomes and organisms--from plants and animals to humans. Highly regarded geneticist Haig Kazazian offers an accessible intellectual history of the field's research strategies and concerns, explaining how advances opened up new questions, and how new tools and capabilities have encouraged progress in the field. Kazazian introduces the key strategies and approaches taken in leading laboratories (including his own) to gain greater insight into the large proportion of our genome that derives from mobile genetic elements, including viruses, plasmids, and transposons. He also presents intriguing insights into long-term research strategies that may lead to an even deeper understanding.

It is said that "necessity is the mother of invention". To be sure, wheels and pulleys were invented out of necessity by the tenacious minds of upright citi zens. Looking at the history of mankind, however, one has to add that "Ieisure is the mother of cultural improvement". Man's creative genius flourished only when his mind, freed from the worry of daily toils, was permitted to entertain apparently useless thoughts. In the same manner, one might say with regard to evolution that "natural selection mere(y tnodifted, while redundanry created". Natural selection has been extremely effective in policing alleHe mutations which arise in already existing gene loci. Because of natural selection, organisms have been able to adapt to changing environments, and by adaptive radiation many new species were created from a common ancestral form. Y et, being an effective policeman, natural selection is extremely conservative by nature. Had evolution been entirely dependent upon natural selection, from a bacterium only numerous forms of bacteria would have emerged. The creation of metazoans, vertebrates and finally mammals from unicellular organisms would have been quite impos sible, for such big leaps in evolution required the creation of new gene loci with previously nonexistent functions. Only the cistron which became redun dant was able to escape from the relentless pressure of natural selection, and by escaping, it accumulated formerly forbidden mutations to emerge as a new gene locus.

This book presents an overview of the state-of-the-art in barley genome analysis, covering all aspects of sequencing the genome and translating this important information into new knowledge in basic and applied crop plant biology and new tools for research and crop improvement. Unlimited access to a high-quality reference sequence is removing one of the major constraints in basic and applied research. This book summarizes the advanced knowledge of the composition of the barley genome, its genes and the much larger non-coding part of the genome, and how this information facilitates studying the specific characteristics of barley. One of the oldest domesticated crops, barley is the small grain cereal species that is best adapted to the highest altitudes and latitudes, and it exhibits the greatest tolerance to most abiotic stresses. With comprehensive access to the genome sequence, barley’s importance as a genetic model in comparative studies on crop species like wheat, rye, oats and even rice is likely to increase.

This unique book explores the role of retrotransposons in human health and disease. The ability of retrotransposons to affect the structure of human genes is recognized since the late 80’s. However, the advances of deep-sequencing technologies have shed new light on the extent of retrotransposon-mediated genome variations. These progresses have also led to the discovery that retrotransposon activity is not restricted to the germline - resulting in inheritable genetic variations - but can also mobilize in somatic tissues, such as embryonic stem cells, neuronal progenitor cells, or in many cancers. This book covers topics related to the effects of retrotransposon insertions, and their consequences on germline and somatic genome dynamics, but also discuss the role and impact of retrotransposons sequences in a broader context, including a number of novel topics that emerged recently (long non-coding RNA, neuronal disorders, exaptation) with unexpected connections between retrotransposons, stem cell maintenance, placentation, circadian cycles or aging.
