Seed Genomics

Informationen zum Autor Philip W. Becraft is Professor in the Department of Genetics, Development, and Cell Biology, and the Department of Agronomy at Iowa State University Klappentext This up-to-date review of seed genomics, from basic seed biology to practical applications in crop science, provides a thorough background understanding of seed biology from a basic science perspective. A valuable resource for advanced graduate students, post-docs, researchers and professionals in the Plant and Crop Sciences, this book brings together top researchers in the field to cover three general themes: genomic approaches to studying seeds, genomic analysis of basic seed biology, and crop seed genomics.A valuable resource for advanced graduate students, post-docs, researchers and professionals in the Plant and Crop Sciences Zusammenfassung This up-to-date review of seed genomics, from basic seed biology to practical applications in crop science, provides a thorough background understanding of seed biology from a basic science perspective.
