Indole-3-acetic acid (IAA) is an endogenous heterocyclic auxin plant hormone derived from indole. IAA is soluble in ethanol but not in water.
|Plant Biology Applications||IAA is an essential compound produced primarily in buds and developing plant leaves which induce transcription of genes involved in cell elongation and cell division in response to light and gravity. In tissue culture, IAA and other auxins are used because of their prominient effects on root formation in undifferentiated callus (Woodward and Bartel, 2005). In addition, IAA has also been shown to induce cell regeneration activity in plants when challenged with wounds.|
