How Auxin stimulates root disk growth?

Auxin, a plant hormone, stimulates root disk growth by promoting cell elongation and division in the root meristem. It influences the distribution of other hormones, such as cytokinins and gibberellins, which further enhance growth processes. Additionally, auxin affects the activity of genes involved in cell wall loosening and expansion, allowing for increased root growth and development. This coordinated hormonal signaling leads to the efficient growth of root structures.
