Involvement of Hormone-and ROS-Signaling Pathways in the Beneficial Action of Humic Substances on Plants Growing under Normal and Stressing Conditions [PDF]
, 2016 The importance of soil humus in soil fertility has been well established many years ago. However, the knowledge about the whole mechanisms by which humic molecules in the rhizosphere improve plant growth remains partial and rather fragmentary.

Metabolism of Indoleacetic Acid in Rust Diseases. II. Metabolites of Carboxyl-labeled Indoleacetic Acid in Tissues [PDF]
Plant Physiology, 1964 In a previous paper (6), we reported different rates of decarboxylation of indoleacetic acid (IAAC14OOH) by healthy and rust-affected wheat leaves in the dark. As a result of infection the rate of decarboxylation first increased, but several days later, as the rust began to sporulate, declined to become much lower than that of healthy leaves.

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 ...

Vagus Nerve Stimulation in Refractory Epilepsy: Effects on Pro- and Anti-Inflammatory Cytokines in Peripheral Blood [PDF]
, 2010 Objective: The vagus nerve has important immunological functions that may be relevant for its anticonvulsive action. We postulate that this anticonvulsive action is activated by a shift in the immune system resulting in a reduction of neurotoxic and an ...

Indoleacetic Acid Oxidase: A Dual Catalytic Enzyme? [PDF]
Plant Physiology, 1972 The isolation of a unique enzyme capable of oxidizing indoleacetic acid, but devoid of peroxidase activity, has been reported for preparations from tobacco roots and commercial horseradish peroxidase. Experiments were made to verify these results using enzyme obtained from Betula leaves and commercial horseradish peroxidase.

Bound Indoleacetic Acid in Avena Coleoptiles [PDF]
Plant Physiology, 1966 When C(14) carboxyl indoleacetic acid (IAA) is transported through Avena coleoptile sections a fraction of the activity becomes bound. The nature of this bound IAA has been investigated. Upon extraction with solvents and chromatography a substance having the R(F) of IAA in 4 solvents was detected.

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.
