Gas chromatography-mass spectrometric analyses of purified extracts from cultures of Rhizobium phaseoli wild-type strain 8002, grown in a non-tryptophan-supplemented liquid medium, demonstrated the presence of indole-3-acetic acid (IAA), indole-3-ethanol (IEt), indole-3-aldehyde and indole-3-methano

## Abstract The direct conversion of indole to indoleβ3βacetic acid without tryptophan as an intermediate has previously been shown to occur __in vivo__, as well as __in vitro__, with seedlings of plants. In order to facilitate the purification of the enzymes that carry out the enzymatic synthesis
## Protoplast preparations from barley (Hordeum vulgare L.) enzymatically converted [5-3H]tryptophan to [3H]indole-3-acetic acid (IAA). Both a chloroplast and a crude cytoplasmic fraction, isolated from protoplasts that had previously been fed [5-3H]tryptophan, contained [3H]IAA. Chloroplast and c
The interaction of free IAA and its amino acid conjugates on growth and development of cultured tomato hypocotyl tissue (Lycopersicon esculentum Mill. cv. Marglobe) was studied. In a nutrient medium containing l0 ~mol/L of benzyladenine, free IAA stimulated shoot and root development with little cal
