Transposable elements, or transposons, make up a significant proportion of the genetic material found in a plant genomes. Now recognized for their ability to illuminate the evolving nature of plants and their day-to-day function, transposable elements are a key component of molecular and genetic research. This book is a comprehensive reference on transposable genetic elements in plants and their impacts on plant evolution and development. It provides broad-ranging coverage of mobile genetic elements and looks at the natural history of transponsons. This book is a single source reference on the diverse and abundant genetic elements found within plants.
