Indole-3-butyric Acid is an important chemical used in plant biology research due to its role as a plant hormone in the auxin family. It is frequently applied in studies of plant tissue culture and root development, where it promotes root initiation and elongation. In horticultural experiments, Indole-3-butyric Acid is used to stimulate the formation of adventitious roots on plant cuttings, thus enhancing vegetative propagation techniques. Its effects on cell division and elongation are also the subject of research, providing valuable information on plant growth and development. Additionally, Indole-3-butyric Acid is used in genetic engineering studies to improve the efficiency of transformation protocols, which involve the integration of new genetic material into plant genomes.
