Book Description
An up-to-date survey of the current exciting state of telomere biology. Telomeres – specialized structures found at the ends of chromosomes – are essential for maintaining the integrity of chromosomes and their faithful duplication during cell division. Chapters in this volume cover telomere structure and function in a range of organisms, focusing on how they are maintained, their roles in cell division and gene expression, and how deficiencies in these structures contribute to cancers and other diseases and even aging.

Book Description
Linear chromosomes represent an evolutionary innovation associated with the origin of eukaryotic cells. This book describes how linear chromosomes and primordial pathways for maintaining their terminal structures, telomeres, emerged in early eukaryotes. Telomeres, derived from the Greek meaning terminal part, were first described by Hermann Muller in 1938. Telomeres are specialized structures that comprise the ends of linear chromosomes in eukaryotes. Linearity is crucial for chromosome pairing during meiosis and sexual reproduction. Inspired by Dobzhansky's dictum that "nothing in biology makes sense except in the light of evolution", this book brings together information about the origin and evolution of telomeres, their functions and the consequences of eukaryotic linearity which is an essential prerequisite of meiotic cell division and sexual reproduction. Selective pressure toward linearization must have been associated with the emergence of robust and redundant mechanisms for the maintenance of telomeres. These pathways comprise a molecular clock involved in cell senescence, carcinogenesis and immortalization.

Book Description
Telomerase, an enzyme that maintains telomeres and endows eukaryotic cells with immortality, was first discovered in tetrahymena in 1985. In 1990s, it was proven that this enzyme also plays a key role in the infinite proliferation of human cancer cells. Now telomere and telomerase are widely accepted as important factors involved in cancer biology, and as promising diagnostic tools and therapeutic targets. Recently, role of telomerase in “cancer stem cells” has become another attractive story. Until now, there are several good books on telomere and telomerase focusing on biology in ciliates, yeasts, and mouse or basic sciences in human, providing basic scientists or students with updated knowledge.

Book Description
Plant research has stood at the forefront of the genomics revolution. One of the first genome projects, the sequencing of the commonly used model organism Arabidopsis, has already yielded important results for the study of a broad array of crops such as corn and soybeans. With crop and food bioengineering only in its infancy, the need to understand the fundamental genetic mechanisms of plants will only become more pressing. A comprehensive guide to this fascinating area of genomics, Plant Genomics and Proteomics presents an integrated, broadly accessible treatment of the complex relationship between the genome, transcriptome, and proteome of plants. This clearly written text introduces the reader to the range of molecular techniques applicable to investigating the unique facets of plant growth, development, and response to the environment. Coverage includes: Functional and structural genomics addressed within the context of current techniques and challenges to come How to utilize DNA and protein sequence data Practical considerations for choosing and employing the most commonly available computer applications A review of applications for biotechnology, including genetic modification and defense against pathogens Bioinformatics tools and Web resources Numerous examples from the latest research throughout Assuming no specialized knowledge of plant biology on the part of its reader, Plant Genomics and Proteomics provides an invaluable resource for students and researchers in biotechnology, plant biology, genomics, and bioinformatics.

Book Description
Life arose on Earth more than three billion years ago. How the first self-replicating systems emerged from prebiotic chemistry and evolved into primitive cell-like entities is an area of intense research, spanning molecular and cellular biology, organic chemistry, cosmology, geology, and atmospheric science. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology provides a comprehensive account of the environment of the early Earth and the mechanisms by which the organic molecules present may have self-assembled to form replicating material such as RNA and other polymers. The contributors examine the energetic requirements for this process and focus in particular on the essential role of semi-permeable compartments in containment of primitive genetic systems. Also covered in the book are new synthetic approaches for fabricating cellular systems, the potentially extraterrestrial origin of life's building blocks, and the possibility that life once existed on Mars. Comprising five sections Setting the Stage, Components of First Life, Primitive Systems, First Polymers, and Transition to a Microbial World it is a vital reference for all scientists interested in the origin of life on Earth and the likelihood that it has arisen on other planets

Book Description
During the last 50 years, the perception oftransposable elements (TEs) has changed considerably from selfish DNA to sequences that may contribute significantly to genome function and evolution. The recent increased interest in TEs is based on the realization that they are a major genetic component (at least 10--20%) of all organisms and a major contributor to the mutation process. It is currently estimated that 70--80% of spontaneous mutations are the result of TE-mediated insertions, deletions, or chromosomal rearrangements. Thus, it seems at least plausible that TEs may playa significant role in the adaptation and evolution of natural populations and species. The ubiquity of TEs suggests that they are an old component of genomes which have been vertically transmitted through generations over evolutionary time. However, detailed analyses carried out over the last 20 years have revealed several unusual features of TE evolution: (i) TEs can be horizontally transferred between species; (ii) TE evolutionary rates can be dramatically increased by specific inactivation processes, such as the RIP (Repeat Induced Point mutation) mechanism in fungi; (iii) TEs can influence the regulation of other TEs by insertion or deletion; (iv) different classes of TEs in even distantly related species can be remarkably similar in both structure and function.
