Abstract excerpt

Weismann's germ plasm theory proposed that germline cells are set aside early in development, ensuring that mutations arising in somatic tissues during an organism's lifetime are not inherited. While this principle has been well supported in animals, it has not been rigorously tested in plants. Plants differ fundamentally from animals in that their meristematic cells drive continuous growth and organ formation...
