Marking the change in focus of tree genomics from single species to comparative approaches, this book covers biological, genomic, and evolutionary aspects of angiosperm trees that provide information and perspectives to support researchers broadening the focus of their research. The diversity of angiosperm trees in morphology, anatomy, physiology and biochemistry has been described and cataloged by various scientific disciplines, but the molecular, genetic, and evolutionary mechanisms underlying this diversity have only recently been explored. Excitingly, advances in genomic and sequencing technologies are ushering a new era of research broadly termed comparative genomics, which simultaneously exploits and describes the evolutionary origins and genetic regulation of traits of interest. Within tree genomics, this research is already underway, as the number of complete genome sequences available for angiosperm trees is increasing at an impressive pace and the number of species for which RNAseq data are available is rapidly expanding. Because they are extensively covered by other literature and are rapidly changing, technical and computational approaches-such as the latest sequencing technologies-are not a main focus of this book. Instead, this comprehensive volume provides a valuable, broader view of tree genomics whose relevance will outlive the particulars of current-day technical approaches. The first section of the book discusses background on the evolution and diversification of angiosperm trees, as well as offers description of the salient features and diversity of the unique physiology and wood anatomy of angiosperm trees. The second section explores the two most advanced model angiosperm tree species (poplars and eucalypts) as well as species that are soon to emerge as new models. The third section describes the structural features and evolutionary histories of angiosperm tree genomes, followed by a fourth section focusing on the genomics of traits of biological, ecological, and economic interest. In summary, this book is a timely and well-referenced foundational resource for the forest tree community looking to embrace comparative approaches for the study of angiosperm trees.

From the cells of aquatic algae to the majestic redwoods towering 100 metres above the California coast, the history of plant evolution has been one of increasing complexity. The underlying rationale for this book is to answer the question: How, when land plant embryos at a few-celled stage are essentially comparable, do plants achieve such radically different adult phenotypes, from mosses to tree-ferns, and grasses to oak trees?
The Molecular Organography of Plants chronicles the origin, and importance, of the complex plant organs that have allowed plants to shape the earth's biosphere, and seeks to explain why and how the genetic mechanisms governing these developmental trajectories have diverged so much. It provides a detailed account of the organs produced by land plants (stems, roots, leaves, seeds, flowers) into which is incorporated what is rapidly becoming known of the molecular mechanisms responsible. Plant organs are therefore discussed in the context of the evolution of development ("evo-devo"), and their basis in molecular developmental genetics is described. The result is a novel synthesis of classical morphology and molecular developmental biology that takes a broad look at the evolution of plant form.
