GeneticsandGenomicsofSoybean,EditedbyProfessorGaryStacey,isaremarkable collection of articles by internationally-recognized experts in the ?eld of soybean genomics – many of whom helped to develop the tools and resources necessary to establish soybean as a powerful crop to investigate important basic and applied questions of plant biology. This collection of articles provides a comprehensive up-to-date review of the ?eld of soybean genomics, and documents how far this ?eld has advanced in the last few years. From the vantage point of someone like myself who ?rst began investigatingthe organizationand expression of the soybean genome thirty years ago, the insights provided by the authors in this book in- cate that soybean has indeed “come of age,” and that decades-old mysteries of the soybean genome are now being illuminated. Genetics and Genomics of Soybean is divided into four sections: (1) soybean genome natural history and diversity – which includes chapters on the genetic variation of the soybean genome and its relationship to other legume genomes; (2) tools, resources, and approaches – which includes reviews of technological advances that are being used to study the s- bean genome – including the ?rst glimpse of how the soybean genome is being sequenced and assembled; (3) investigations of soybean biology – which contains chapters that review how genomics tools have been used to study important qu- tions – such as seed development, host-pathogen interactions, abiotic stress, and metabolic pathways; and (4) how Roundup Ready soybeans, generated by genetic engineering, have made an impact on global soybean agriculture.
