The Binding of Indole-3-acetic Acid and 3-Methyleneoxindole to Plant Macromolecules.
Homogenates of pea (Pisum sativum L., var. Alaska) seedlings exposed to (14)C-indole-3-acetic acid or (14)C-3-methyleneoxindole, an oxidation product of indole-3-acetic acid, were extracted with phenol. In both cases 90% of the bound radioactivity was found associated with the protein fraction and 10% with the water-soluble, ethanol-insoluble fraction. The binding of radioactivity from (14)C-in...
متن کاملInhibitory oxidation products of indole-3-acetic Acid: 3-hydroxymethyloxindole and 3-methyleneoxindole as plant metabolites.
Extracts of pea seedlings (Pisum sativum, variety Alaska) oxidize indole-3-acetic acid to a bacteriostatic compound which has been identified as 3-hydroxymethyloxindole. At physiological pH this compound is readily dehydrated to 3-methyleneoxindole, another bacteriostatic agent. The extracts of pea seedlings also contain a reduced triphosphopyridine nucleotide-linked enzyme which reduces 3-meth...
متن کاملIndole-3-acetic acid in microbial and microorganism-plant signaling.
Diverse bacterial species possess the ability to produce the auxin phytohormone indole-3-acetic acid (IAA). Different biosynthesis pathways have been identified and redundancy for IAA biosynthesis is widespread among plant-associated bacteria. Interactions between IAA-producing bacteria and plants lead to diverse outcomes on the plant side, varying from pathogenesis to phyto-stimulation. Review...

متن کاملThe Nitrilase ZmNIT2 converts indole-3-acetonitrile to indole-3-acetic acid.
We isolated two nitrilase genes, ZmNIT1 and ZmNIT2, from maize (Zea mays) that share 75% sequence identity on the amino acid level. Despite the relatively high homology to Arabidopsis NIT4, ZmNIT2 shows no activity toward beta-cyano-alanine, the substrate of Arabidopsis NIT4, but instead hydrolyzes indole-3-acetonitrile (IAN) to indole-3-acetic acid (IAA). ZmNIT2 converts IAN to IAA at least se...
