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.

Hormonal Status of Transgenic Birch with a Pine Glutamine Synthetase Gene during Rooting In Vitro and Budburst Outdoors

Biomolecules, 2023
Improving nitrogen use efficiency (NUE) is one of the main ways of increasing plant productivity through genetic engineering. The modification of nitrogen (N) metabolism can affect the hormonal content, but in transgenic plants, this aspect has not been ...

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 ...

Genome-Wide Identification, Functional Analysis and Expression Profiling of the Aux/IAA Gene Family in Tomato [PDF]

, 2012
Auxin is a central hormone that exerts pleiotropic effects on plant growth including the development of roots, shoots, flowers and fruit. The perception and signaling of the plant hormone auxin rely on the cooperative action of several components,among

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.

Horseradish and soybean peroxidases: comparable tools for alternative niches? [PDF]

, 2006
Horseradish and soybean peroxidases (HRP and SBP, respectively) are useful biotechnological tools. HRP is often termed the classical plant heme peroxidase and although it has been studied for decades, our understanding has deepened since its cloning and ...

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.

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.
