This book covers a wide area of concepts and methods in genomics. These range from international genome sequencing projects, to invaluable bioinformatics tools, and analytical methods of gene exoression, including final metabolic products and thier specific tussue and cellular compartmentalization. This new knowledge enables raders to understand the integration of basic physiological functions, and developmental programs. Also, the estabishment of tight relationships between genomics, and genetics and plant breeding reveals synergies for exploiting molecular markers, for analysing, genetic variation, or for studying quantitative traits. The integration that is now feasible by these new approaches also effects ecophysiology, and opens up new perspectives for the use of modelling for the study of plant populations. This book is intended for advanced students in botany and agronomy, their lecturers, and for all scientists who wish to understand plant genomics rapidly, in a relatively exhaustive and synthetic form.
