Indole-3-butyric acid potassium salt (CAS 60096-23-3)

Indole-3-butyric acid potassium salt serves as a plant growth regulator employed in plant tissue culture and propagation to facilitate root development. It aids in the formation of roots on plant cuttings by stimulating critical processes such as cell division and elongation at the root meristem. Functioning at a molecular level, it enhances the transcription of specific genes that are vital for root differentiation and development. Indole-3-butyric acid potassium salt synergistically interacts with the plant′s intrinsic auxin signaling pathway, which is instrumental in triggering root primordia and encouraging the growth of adventitious roots. It plays a significant role in managing the transport and distribution of auxin within the plant, thereby helping to establish a robust and functional root system. Its influence extends to the modulation of auxin-responsive gene expression, which is fundamental in promoting vigorous root growth and development across a diverse range of plant species.
