This book is the first volume of a comprehensive assemblage of contemporary knowledge relevant to genomics and other omics in date palm. Volume 1 consists of 11 chapters arranged in 3 parts grouped according to subject. Part I, Biology and Phylogeny, focuses on date palm biology, evolution and origin. Part II, Biodiversity and Molecular Identification, covers conformity of in vitro derived plants, molecular markers, barcoding, pollinizer genetics and gender determination. Part III, Genome Mapping and Bioinformatics, addresses genome mapping of nuclear, chloroplast and mihondrial DNA, in addition to a chapter on progress made in date palm bioinformatics. This volume represents the efforts of 30 international scientists from 10 countries and contains 78 figures and 30 tables to illustrate presented concepts. Volume 2 is published under the title: Omics and Molecular Breeding.
