Auxin is not a hormone that regulates the stages of digestion. Auxin can only be found in plants. They are hormones in plants that cause the elongation of cells in shoots.

In present time, these hormones are artificially produced in laboratories because they are used in the agriculture industry to speed up plant growth and regulate how fast the fruits will ripen.
