Auxin

What is Auxin?

Auxin is a plant hormone that regulates plant growth and development in different environmental conditions. 

Where is Auxin in a Plant?

Auxin is a plant hormone that is produced in the tips of growing roots and stems, also known as apical meristems. It can also be produced in other areas of the plant, including: Differentiating tracheary elements, Root cap cells, Nutritive tissues in developing seeds and flowers, Senescent leaves, and Wounds.

Why is Auxin a Hormone?

Auxin is a plant hormone because it can stimulate different growth in response to light or gravity.

What are 3 Functions of Auxins?

Auxins regulate plant growth, promote phototropism, and stimulate root initiation.

Who Discovered Auxin?

The Dutch biologist Frits Warmolt Went first described auxins and their role in plant growth in the 1920s. 

What is an Example of an Auxin?

Indole-3-acetic acid (IAA) is a prominent natural auxin found in plants, regulating various growth and developmental processes.

How to Use Auxin?

Auxin can be applied topically or via root drench to promote root formation in plant cuttings.

Auxin is a plant hormone. Auxin hormone function is to control growth and developmental processes in plants, including cell expansion, root initiation, and bud and flower growth. Auxin, discovered by Charles Darwin and his son Francis, was first isolated from human urine.

Auxin plays a key role in plant adaptation to the environment, and its functions are associated with signal transduction, transport, homeostasis, and biosynthesis pathways. In this article, we will study the auxin, its types, mechanism of action, and functions in detail.
