Book Description
The global triumph of Mendelian genetics in the twentieth century was not a foregone conclusion, thanks to the existence of graft hybrids. These chimeral plants and animals are created by grafting tissue from one organism to another with the goal of passing the newly hybridized genetic material on to their offspring. But prevailing genetic theory insisted that heredity was confined to the sex cells and there was no inheritance of characteristics acquired during an organism’s lifetime. Under sustained attacks from geneticists, scientific belief in the existence of graft hybrids slowly began to decline. Yet ordinary horticulturalists and breeders continued to believe in the power of grafting. Matthew Holmes tells the story of these organisms—which include multicolored chickens and black nightshades that grew tomatoes—and their enduring influence on twentieth-century biology. Their creators sought a goal as ambitious as the wildest dreams of genetic engineering today: to smash the barriers between species and freely exchange genes between organisms. The Graft Hybrid presents a greater understanding of the controversial history of graft hybrids, offering a crucial intervention in the history of genetics and the future of biological science.

Book Description
Plant Breeding Reviews is an ongoing series presenting state-of-the art review articles on research in plant genetics, especially the breeding of commercially important crops. Articles perform the valuable function of collecting, comparing, and contrasting the primary journal literature in order to form an overview of the topic. This detailed analysis bridges the gap between the specialized researcher and the broader community of plant scientists.

Book Description
This book, which was originally published in 1986, introduces the reader to the main steps in the analysis of chimeras, explains their structural and developmental basis, and the ways of classifying and manipulating them. The twelve chapters separate types of chimeras according to their origin - by grafting or polyploidy; their structure - sectorial or periclinal; or according to the varied parts of the plant most affected - tubers, leaves, flowers or fruit. Throughout the book care is taken to distinguish between the activity of the growing-point in determining chimera structure, and the role of gene expression in determining appearance. Examples of the experimental uses of chimeras are given and of the valuable role they can play in studying fundamental questions of anatomical development; the disadvantages of chimeras in mutation breeding are discussed too.

Book Description
Darwin's Pangenesis and its Rediscovery Part B explores Darwin's Pangenesis, an expanded cell theory and unified theory of heredity and variation from over 150 years ago that strengthened his theory of evolution and explained many phenomena of life. Now, new discoveries on circulating DNA, mobile RNAs, prions and extracellular vesicles are providing striking evidence for the chemical existence of Darwin's imaginary gemmules. In addition, new evidence for the inheritance of acquired characters, graft hybridization, and many other phenomena that Pangenesis supposedly explains are progressing, and are hence explored in this comprehensive volume. Specific chapters in this new volume include Darwin and Mendel: The Historical Connection, Darwin's Pangenesis and Graft Hybridization, Darwin's Pangenesis and Medical Genetics, Darwin's Pangenesis and Certain Anomalous Phenomena, and Natural Selection and Pangenesis: The Darwinian Synthesis. - Presents the only book on Darwin's Pangenesis, an expanded cell theory and a unified theory of heredity, variation, development and reproduction - Highlights Darwin's tremendous contributions to genetics, as well as Mendel's legacy and limitations - Includes sections on Darwin's Pangenesis in relation to graft hybridization, medical genetics, evolutionary theory, along with many other updates

Book Description
Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops.
