Explanation:

Auxins are a class of plant hormones (or plant growth regulators) with some morphogen-like characteristics. Auxins have a cardinal role in the coordination of many growth factors.

• When a plant cell comes into contact with auxin, it causes dramatic changes in gene expression, with many genes up- or down-regulated. It is the molecular mechanism of the Auxin.

• Auxin response factors (ARFs) are a large group of transcription factors that act in auxin signaling.

• On the cellular level, auxin is essential for cell growth, affecting both cell division and cellular expansion.

• Growth and division of plant cells together result in the growth of tissue, and specific tissue growth contributes to the development of plant organs.

• Local auxin maxima can be formed by active biosynthesis in certain cells of tissues, for example via tryptophan-dependent pathways, but auxins are not synthesized in all cells (even if cells retain the potential ability to do so, only under specific conditions will auxin synthesis).

• As auxins contribute to organ shaping, they are also fundamentally required for proper development of the plant itself.
