Overview

Seed Genomics / Edition 1

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.
