Stage of Development: Embryo
Embryonic development of the plant, Arabidopsis thaliana from heart stage (left) through torpedo stage (right). The expression pattern of the transcription factor KAN2 (green) defines the abaxial/peripheral domain of the embryo and shoot. All of these stages take place within a seed. The embryo forms the meristems (undiffentiated tissue) which give rise to all of the organs (leaves, flowers and roots) that we see in a mature plant.
