- Description:
- Effects of indoleacetic acid and some of its reported precursors (indolepyruvic acid, indoleacetaldehyde, and tryptamine) on growth of bean hypocotyl and wheat coleorhiza- epiblast were studied. The influence of these test compounds on protein synthesis and free amino acid content of the target tissues was examined. Data derived from these studies were used to deduce the most probable pathway of indoleacetic acid biosynthesis operative in the systems specified, i.e., whether indoleacetic acid biosynthesis proceeds from tryptophan > indolepyruvic acid > indoleacetaldehyde > indoleacetic acid, or from tryptophan > tryptamine > indoleacetalde�hyde indoleacetic acid. It was assumed that actual precursors of indoleacetic acid would have an effect similar to that of indoleacetic acid.
