متن کاملDetermination of Free and Total Indole-3-acetic Acid and of the Indole Index.
A new method is described for measurement of the urinary excretion of free and total indole-3-acetic acid and for obtaining the chromogenic value of the total indoles. The color reaction employed is Fischl’s (1) tryptophan reaction. Hydrolysis and extractions were done by Weissbach’s (2) procedure. The ratio of the various fractions is expressed by a new term: “indole index” (1.1.). By the eval...
متن کاملThe conjugated auxin indole-3-acetic acid-aspartic acid promotes plant disease development.
Auxin is a pivotal plant hormone that regulates many aspects of plant growth and development. Auxin signaling is also known to promote plant disease caused by plant pathogens. However, the mechanism by which this hormone confers susceptibility to pathogens is not well understood. Here, we present evidence that fungal and bacterial plant pathogens hijack the host auxin metabolism in Arabidopsis ...
متن کاملInactivity of Oxidation Products of Indole-3-acetic Acid on Ethylene Production in Mung Bean Hypocotyls.
The suggestion that indole-3-acetic acid (IAA)-stimulated ethylene production is associated with oxidative degradation of IAA and is mediated by 3-methyleneoxindole (MOI) has been tested in mung bean (Phaseolus aureus Roxb.) hypocotyl segments. While IAA actively stimulated ethylene production, MOI and indole-3-aldehyde, the major products of IAA oxidation, were inactive. Tissues treated with a...
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...
