Genetic Mechanisms of Development is a compilation of articles that surveys the application of genetic systems of analysis to the resolution of fundamental problems in developmental biology. The book is composed of sections that deal with various aspects of genetic mechanisms. The first section tackles the genetic analysis of gene regulation in microorganisms. The second section discusses the application of Mendelian genetics to the study of the development of Drosophila, amphibians, and the laboratory mouse. The last section introduces somatic cell genetics, a tool for developmental biologists. Biologists, geneticists, zoologists, and researchers will find the book a good source of information.

Although as part of my general plan, this book is a continua tion of my earlier monograph "Protein Biosynthesis and Problems of Ontogenesis,"* published in 1963, in all other respects it is an independent work. The earlier monograph was devoted to the analysis of many of the aspects of the problem of protein biosynthesis, and problems of inheritance and development were discussed only insofar as they are derivatives of the problems of biosynthesis. The complex act of protein biosynthesis, comprising autore production of the genetic material (DNA), formation of the templates of protein synthesis (messenger RNA), synthesis of amino acid carriers (transfer RNA), formation of ribosomes and polysomes, activation of amino acids, and so on, was examined in the previous monograph not merely from the standpoint of interaction between the components of this system, but also from that of their mani festation in actual biological systems during morphogenesis and aging of the organism. However, both morphogenesis and aging were investigated very generally, Simply as models, without any detailed analysis of their specific features and complexity. The present book is therefore a logical continuation of its prede cessor. It rests largely on a comprehensive analysis of the molecular-genetic and biochemical aspects of development and differentiation of living organisms, and questions of protein biosyn thesis are discussed briefly and generally, and only so far as is necessary for fulfillment of the primary task. • Zh.

Molecular Genetic Mechanisms in Development and Aging discusses the mechanisms of aging at the level of the genome. This book explores the fundamental knowledge concerning the regulation and expression of gene, which is derived from investigations on microbial organisms. Organized into nine chapters, this book starts with an overview of the molecular genetic basis for the processes of aging. This text then explores the highly complex multicellular members of the class Insecta, which provide the researcher with many distinct and unique advantages for aging studies. Other chapters discuss the mechanisms of genetic control and organization during the development and aging of eukaryotes, which pose some challenging problems in cellular and developmental biology. The final chapter deals with the limitations of previous studies, including the lack of comparability due to differences in techniques, the measuring of free amino acid titers in hemolyph only, and differing diet and environmental variations. Biologists and students interested in developmental and molecular genetics will find this book useful.

An outstanding group of scientists have collaborated in the collection of case studies that comprise this major text-reference book. It examines in detail how genes operate in diverse living systems, including viruses, cells and more complex organisms; investigates how genotypes can be altered; and looks at the mapping and sequencing of human and other genomes. Students and professionals in biochemistry, molecular biology and genetics will enjoy this book.

Gender (sex) is a set of morphological and physiological characteristics of the organism underlying sexual reproduction, the essence of which is reduced to fertilization, i.e. the fusion of male and female gametes (gametes) zygote, which develops into a new organism.Sexual reproduction of a species is considered as one of the mechanisms of its homeostasis. Thanks to this mechanism, numerous species have an evolutionary advantage. In the book, two authors will discuss the types of genetic sex determination and differentiation, mostly in multicellular animal organisms. Sex determination is both genetic and environmental process, the sex of an individual being established through an alternative physiological solution. There are two main postulated mechanisms of sex determination: genetic (GSD, Genetical Sex Determination) and environmental (ESD, Environmental Sex Determination).

This book is intended for a wide range of individuals, including scientists, students and informed laypersons who are interested in agricultural biotechnology, alternative agriculture, bioremediation of the environment and decreasing our reliance on pesticides and fungicides. It will deal primarily with understanding, at a biochemical and molecular biological level, how certain free living bacteria are able to promote plant growth; symbiotic bacteria such as Rhizobia will be mentioned only briefly. The assumption underlying the entire endeavour will be that a more profound understanding of these fundamental mechanisms will eventually permit scientists to manipulate these bacteria and use them more efficiently as a regular component of agricultural and/or horticultural practice. Therefore, while all the topics are discussed in as comprehensive a manner as possible, the book emphasizes a critical overview of the field rather than a mere compendium of data.

Cardiovascular disease (CVD) and neurodevelopmental disorders (NDD) are both common diseases seriously affecting human health. CVD refers to a broad range of disorders including diseases affecting the vasculature, the myocardium, the heart’s electrical circuit, and congenital heart disease. NDDs are conditions affecting brain development and function, mainly characterized by impairments of cognition, communication, and motor skills. Although the heart and brain develop in spatially distinct regions, they share similar genetic factors and molecular pathways which are crucial for a precise developmental trajectory. Actually, congenital CVD survivors are at a higher risk of NDD, and whole-exome sequencing revealed a significant overlap between high-risk congenital CVD and NDD genetic variants. For CVD and NDD, the clinical presentations are heterogeneous, and the etiologies are complex. Elucidating the potential pathogenic mechanisms is good for unveiling the pathophysiology and finding the novel therapeutic target.
