We propose a role for the plant hormone auxin as an integrator of the activities of multiple plant hormones to control plant growth in response to the environment. Plants are sessile organisms and ...

Polar auxin transport is tightly regulated, and the hormone has a cardinal role in almost all important processes of a plant's life cycle, such as shoot and root growth, development, cell ...

Most natural rooting hormone contains actual auxin, also known as indole-3-acetic acid (IAA.) Natural rooting powder contains ...

This is just like phototropism, in that auxin in the root inhibits growth and auxin in the stem promotes growth.

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 ...

controls its own expression and the expression of its inhibitor BODENLOS (BDL), with the plant hormone auxin acting as a threshold-specific trigger by promoting the degradation of the inhibitor.
