indoleacetic acid
Auxin growth regulator
Indoleacetic acid is the principal natural auxin—a plant hormone that regulates growth.
It controls cell elongation, root development, and responses to light and gravity.
Abbreviated IAA.
The compound is also produced by certain bacteria, which can affect plant health when they colonize roots.
