Book Description
It is generally accepted that all living organisms present on earth derive from one single primordial cell born several billion years ago. One important step in the evolution occurred some 1. 5 billion years ago with the transition from small procaryote cells with relatively simple internal structures such as bacteria to larger and more compleX: eucaryotic cells such as those found in higher animals and plants. Large membrane proteins which enable the cells to communicate appeared early in evolution, and it is believed that the nerve membrane receptors and ionic channels which are observed today in both invertebrate and vertebrate species derive from a common ancestor. Basically, the three identified superfamilies, 1) ionotropic receptors (i. e. receptors containing an integral ionic channel), 2) metabotropic receptors (receptors coupled to G proteins) and 3) voltage-dependent ionic channels (Na+, K + and Ca2+ channels) were already well differentiated when vertebrates separated from invertebrate species. The large number of subtypes which are observed in each superfamily may be of more recent evolutionary origin. To understand how this happened, the best approach was to compare the sequences and the properties of the receptors and ionic channels in species sufficiently distant in the evolutionary tree. In the present volume, many of the best specialists in the field of comparative molecular neurobiology, several of them working on vertebrate and invertebrate species, have accepted to report their most recent findings.

Book Description
Connects classical cellular descriptive studies with more recent work on the molecular and genetic aspects regarding germline development. Prominent scientists discuss research on a range of organisms including insects, worms, birds, fish, amphibia, mammals and green algae. Specification of germ cells, their migration to the gonads and subsequent interactions with the soma and evolutionary factors of their segregation are among the topics covered.

Book Description
Whereas genetic studies have traditionally focused on explaining heritance of single traits and their phenotypes, recent technological advances have made it possible to comprehensively dissect the genetic architecture of complex traits and quantify how genes interact to shape phenotypes. This exciting new area has been termed systems genetics and is born out of a synthesis of multiple fields, integrating a range of approaches and exploiting our increased ability to obtain quantitative and detailed measurements on a broad spectrum of phenotypes. Gathering the contributions of leading scientists, both computational and experimental, this book shows how experimental perturbations can help us to understand the link between genotype and phenotype. A snapshot of current research activity and state-of-the-art approaches to systems genetics are provided, including work from model organisms such as Saccharomyces cerevisiae and Drosophila melanogaster, as well as from human studies.
