Until very recently, genetic maps of higher plants were based almost entirely on morphological and biochemical traits. These maps are rapidly being replaced and/or supplemented with DNA-based marker maps based on the use of powerful new molecular techniques. The new high-precision maps can be developed with comparative ease and rapidity. They have a much higher density of markers, which allows revelation of more and more restricted segments of the genome. One of the many revolutionary aspects of this technology is that linkage between molecular markers and traits of interest can often be detected in a single cross. The ability to hybridize probe after probe to the DNA of the same individuals of a segregating population allows one to pursue the analysis until linkage becomes evident. With morphological and biochemical markers used previously, a separate cross was required to test linkage with each new marker. It was seldom that more than three markers could be tested for linkage with the trait of interest in a single cross because of viability problems.With the new techniques described in this volume, a new gene could be placed on the linkage map within a few days instead of the much longer time required with the previous techniques. In this book, a group of leading researchers provide background information and current versions of DNA-based marker maps for a variety of crops. These maps illustrate the state of the art today.

The Plant Seed: Development, Preservation, and Germination presents papers delivered on the symposium on plant seed, held at the University of Minnesota in 1978. The volume discusses the development, preservation, and germination of the plant seed. The topics of this compendium focus on various aspects of the plant seed. The first group of papers describes genetic, hormonal, and molecular events associated with seed development, with particular attention given to the molecular biology of storage protein formation; the second group of papers examines the physiological and genetic aspects of germplasm preservation. The final group of papers examines the molecular aspects of seed germination. The book will be of interest to botanists, biologists, plant breeders, plant physiologists, plant pathologists, and geneticists.

Molecular Genetic Modification of Eucaryotes reviews the current state of knowledge and techniques potentially useful for the molecular genetic modification of eucaryotes. The book interfaces molecular genetics, plant cell and tissue culture, and plant improvement. Topics include cell and tissue culture, protoplasts, somatic cell fusion, cellular mutagenesis, regeneration of new plant types, and the applicability of these techniques to plant improvements. Viruses and viral integration; integration and expression of foreign genetic material in human cells, Drosophila, plant cells, and legumes; biophysical studies of DNA uptake by plants; and genetic engineering for plant protection against diseases are also discussed in detail. The book will be of interest to geneticists, cell biologists, plant breeders, plant physiologists, plant pathologists, and biochemists.
