Researchers from the University of Tasmania have provided new insights into auxin, a master plant hormone, and its vital role in starch production—the powerhouse of the world's most important crops.

This chemical is produced commercially and contains indole-3-butyric acid (IBA,) an artificial version of the natural plant hormone auxin. Naphthalene acetic acid (NAA) is another synthetic ...

What UTAS researchers have uncovered about this “natural booster”. University of Tasmania scientists have unveiled new research into the vital role played by auxin in regulating starch production in ...

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 ...

In a stem, the cells on the shaded side contain more auxin and grow longer than the cells on the light side. This causes the stem to grow towards the light. It is vital to note that the plant does ...
