Plant hormones animation: How IAA, the most common form of auxin, works

Watch or download our animation, which explores the action of indole-3-acetic acid (IAA), the most common form of auxin, and looks at how scientists used experimental evidence to explain the role of auxins in a phototrophic response 

We’ve also produced a Powerpoint presentation using still images from the animation, which you can download from the bottom of the page. This presentation does not have any explanatory text so it is particularly useful for revision.
