suggesting that it may regulate cell division or elongation at different stages through the mediation of auxin action, and coordinate the transition between them. The downregulation of IuEXT ...

Auxin, by its mobile nature, is used to coordinate hormone action across tissues and organs. An emerging theme is that environmental and hormone pathways can be integrated during signaling by hubs ...

Just like phototropism, gravitropism is also caused by an unequal distribution of auxin. When a stem is placed horizontally, the bottom side contains more auxin and grows more - causing the stem ...
