Promotion of Indoleacetic Acid Oxidase Isoenzymes in Tobacco Callus Cultures by Indoleacetic Acid [PDF]
Plant Physiology, 1971 Indoleacetic acid oxidase in tobacco callus cultures (Nicotiana tabacum L., cv. White Gold) was composed of at least two groups of isoenzymes, which were distinctly different in electrophoretic mobilities and in responses to growth substances. Indoleacetic acid had dual effects; at low concentrations it promoted the development of two fast-migrating ...

Formation of indoleacetic acid by intestinal anaerobes [PDF]
Journal of Bacteriology, 1975 Indoleacetic acid was produced from tryptophan by only three of 23 intestinal anaerobes studied. Evidence is presented to show that the formation of indoleacetic acid proceeds through the intermediate, indolepyruvic acid, via transamination with alpha-ketoglutarate rather than by tryptamine pathway.

Biological Activity of Vegetal Extracts Containing Phenols on Plant Metabolism
Molecules, 2016 The influence of vegetal extracts derived from red grape, blueberry fruits and hawthorn leaves on Zea mays L. plant growth and the activity of phenylalanine ammonia-lyase (PAL), a key enzyme of the phenylpropanoid pathway, was investigated in laboratory ...

The destruction of indoleacetic acid. III. Relationships between peroxidase action and indoleacetic acid oxidation [PDF]
Archives of Biochemistry and Biophysics, 1960 Abstract The indoleacetic acid (IAA)-oxidizing enzyme preparation from Omphalia flavida exhibits peroxidase activity on pyrogallol with an optimum at pH 3.5–3.7, like that for the IAA-oxidizing activity. It shows no polyphenolase activity. Peroxidase and IAA-oxidizing activities run parallel both during thermal inactivation and in course of ...

Indoleacetic Acid Studies in Man.
Experimental Biology and Medicine, 1948 SummaryThe addition of 25 to 200 mg of indoleacetic acid per day to a diet low in protein and nicotinic acid appears to have no significant effect upon the utilization of tryptophane and nicotinic acid by man as evidenced by urinary excretion studies.

Root Meristem Maintenance Mechanisms are Key to Plant Defense Against Nanoplastics
Advanced Science, EarlyView.Small nanoplastics can disrupt cell integrity and inhibit cell division in meristem zone of plant root. The plants can counteract the cell damage by upregulating genes associated with root meristem maintenance and increasing auxin accumulation by PIN2 transport inhibition.
