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 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.
متن کاملConversion of endogenous indole-3-butyric acid to indole-3-acetic acid drives cell expansion in Arabidopsis seedlings.
Genetic evidence in Arabidopsis (Arabidopsis thaliana) suggests that the auxin precursor indole-3-butyric acid (IBA) is converted into active indole-3-acetic acid (IAA) by peroxisomal beta-oxidation; however, direct evidence that Arabidopsis converts IBA to IAA is lacking, and the role of IBA-derived IAA is not well understood. In this work, we directly demonstrated that Arabidopsis seedlings c...
متن کاملIndole-3-acetic acid metabolism in Lemna gibba undergoes dynamic changes in response to growth temperature.
Auxin is the mobile signal controlling the rate of growth and specific aspects of the development of plants. It has been known for over a century that auxins act as the messenger linking plant development to specific environmental changes. An often overlooked aspect of how this is accomplished is the effect of the environment on metabolism of the major plant auxin, indole-3-acetic acid (IAA). W...
