Mendel worked on garden pea in his genetic experiments. Darwin and his son Francis Darwin observed that the coleoptiles of canary grass responded to unilateral illumination by growing towards the light source (phototropism). Auxin was isolated by F.W. Went from tips of coleoptiles of oat seedlings. Priestley used mint plant in his experiments to reveal the essential role of oxygen.
