Plant Transposons and Genome Dynamics in Evolution.
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 res...
