Bacterial indole-3-acetic acid: A key regulator for plant growth, plant-microbe interactions, and agricultural adaptive resilience.

Microbiology Research
Indole-3-acetic acid (IAA), a fundamental phytohormone categorized under auxins, not only influences plant growth and development but also plays a critical role in plant-microbe interactions.

Labelling indole-3-acetic acid with tritium

Journal of Radioanalytical and Nuclear Chemistry Letters, 1986
A simple method of obtaining indole-3-acetic acid/ growth stimulating plant hormone/ labelled with tritium has been described. The preparate has specific radioactivity of 455 MBq/mmol, and 50% yield as compared to the initial amount of used substance.

Colorimetric estimation of indole-3-acetic acid

Analytical Biochemistry, 1976
Abstract After oxidation of indole-3-acetic acid with ceric nitrate in the presence of hydroxylamine, a stable colored complex extractable to isoamyl alcohol is formed. This reaction is useful for the colorimetric estimation of indole-3-acetic acid in biological mixtures.

Indole-3-Acetic Acid Induces Microencephaly in Rat Fetuses

Toxicologic Pathology, 2004
Indole-3-acetic acid (IAA), known as natural auxin, induces cleft palate in rodents. However, there has been no report about the neurodevelopmental toxicity of IAA in rats. In the present study, we found microencephaly in the fetuses from the rats exposed to IAA. The purpose of this work was to examine the effects of IAA administration in pregnant rats

Indole-3-acetic acid induces microencephaly in mouse fetuses

Experimental and Toxicologic Pathology, 2007
To determine the effect of indole-3-acetic acid (IAA), known as natural auxin, on developing fetus, pregnant mice were injected with 500 or 1000 mg/kg on various gestation days (Days). With the repeated treatment during Days 7-15, the fetal brains exhibited a reduction in size and weight in a dose-dependent manner on Day 18.

Gibberellin‐enhanced indole‐3‐acetic acid biosynthesis: D‐Tryptophan as the precursor of indole‐3‐acetic acid

Physiologia Plantarum, 1987
Stem segments excised from light‐grown Pisum sativum L. (cv. Little Marvel) plants elongated in the presence of indole‐3‐acetic acid and its precursors, except for L‐tryptophan, which required the addition of gibberellin A, for induction of growth. Segment elongation was promoted by D‐tryptophan without a requirement for gibberellin, and growth in the ...

Azospirillum-Gramineae Interaction: Effect of Indole-3-Acetic Acid

1991
To evaluate the involvement of indole-3-acetic acid (IAA) in promoting plant response the effects of inoculation of wheat seeds with Azospirillum brasilense SpM7918, a very low IAA producer selected after Tn5 mutagenesis, have been compared with those caused by the inoculation with the wild type strain Sp6.

OpticalIy Pumped Chemiluminescence of Indole‐3‐Acetic Acid

Photochemistry and Photobiology, 1996
ABSTRACTOptically pumped chemiluminescence of indole‐3‐acetic acid (IAA) was observed and studied. Rose Bengal (RB) was used as a photosensitizer. Long‐lived chemiluminescence (CL) appeared after irradiation of the IAA/RB reaction mixture by monochromatic light at 550 nm (the maximum of RB absorption) or by visible light.

Diorganotin(IV) complexes of indole 3‐acetic acid

Applied Organometallic Chemistry, 1993
AbstractAlkyl derivatives of indole 3‐acetic acid (IAA) have been prepared and are suitable for investigating steric substituent effects on hormonal activity without major interference from electronic effects. Triorganotin(IV) derivatives of indole 3‐acetic acid and N‐methylindole 3‐acetic acid have been reported to act as insecticidal, fungicidal and ...

Synthesis of Indole-3-acetic acid and Indole-3-butyric acid Loaded Zinc Oxide Nanoparticles: Effects on Rhizogenesis.

Journal of Biotechnology, 2019
The aim of this work was to investigate the use of zinc oxide nanoparticles (nZnO) as nanocarriers for plant auxins indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) and determine the effects on rhizogenesis in micro cuttings of different Pyrus ...
