متن کاملMetabolism of Indole-3-acetic Acid: IV. Biological Properties of Amino Acid Conjugates.
The biological activity of 20 l-alpha-amino acid conjugates of indole-3-acetic acid (IAA) to stimulate cell elongation of Avena sativa coleoptile sections and to stimulate growth of soybean cotyledon tissue cultures has been examined at concentrations of 10(-4) to 10(-7)m. In the Avena coleoptile test, most of the amino acid conjugates stimulated elongation. Several of the conjugates stimulated...
متن کاملOxindole-3-acetic Acid, an Indole-3-acetic Acid Catabolite in Zea mays.
A prior study (13) from this laboratory showed that oxidation of exogenously applied indole-3-acetic acid (IAA) to oxindole-3-acetic acid (OxIAA) is the major catabolic pathway for IAA in Zea mays endosperm. In this work, we demonstrate that OxIAA is a naturally occurring compound in shoot and endosperm tissue of Z. mays and that the amount of OxIAA in both shoot and endosperm tissue is approxi...
متن کاملQuantitative analysis of indole-3-acetic acid metabolites in Arabidopsis.
A general gas chromatography/mass spectrometry (MS)-based screen was performed to identify catabolites and conjugates of indole-3-acetic acid (IAA) during vegetative growth of Arabidopsis. This experiment revealed the existence of two new conjugates: N-(indole-3-acetyl)-alfa-alanine (IA-Ala) and N-(indole-3-acetyl)-alfa-leucine (IA-Leu). A method for quantitative analysis of IAA metabolites in ...
متن کاملConversion of indole-3-ethanol to indole-3-acetic Acid in cucumber seedling shoots.
Indoleethanol-(14)C was applied to intact cucumber seedlings and to hypocotyl segments. The presence of indoleacetic acid-(14)C in tissue extracts was demonstrated by thin layer radiochromatography. There was no evidence of conversion of indoleacetic acid to indoleethanol. It is suggested that the growth-promoting activity of indoleethanol is due to its conversion to indoleacetic acid.
