The wide use of the auxin, indoleacetic acid, in physiological and biochemical experiments has promoted interest in methods for its colorimetrie estimation. Mitchell and Brunstetteb (1) have proposed both the nitrite and the ferric chloride-sulphuric acid tests for the quantitative estimation of indoleacetic acid (IAA) in aqueous solutions, basing their suggested procedures upon a study of optimal reaction conditions for these two reagents. According to them, the nitrite method is sensitive to…

Indoleacetaldehyde in Cucumber Seedlings 1
The presence of indoleacetaldehyde in cucumber (Cucumis sativus L.) cotyledons was demonstrated by thin layer chromatographic RF values in three solvent systems, by the formation and hydrolysis of a
Quantitative Determination of Indole‐3‐Acetaldehyde. II.
The method by Larsen and Klungsoyr (1964) for the quantitative determination of indole-3-acetaldehyde (IAAld) was modified for the purpose of eliminating the need for filtration after oxidation of
Soybean temperature-dependent hypocotyl growth anomaly: physiological aspects
A reagent for indole-3-acetic acid has been formulated using O.OIM Fe(N0g)g"9H20 in 5.8N HCIO^. The reagent has been comparatively tested against other reagents for indole-3-acetic acid and has been
Isolation of Indole-3-ethanol Oxidase from Cucumber Seedlings.
TLDR
An enzyme is isolating from cucumber seedlings which catalyzes the oxidation of IEt to indole-3-acetaldehyde (IAAld), which has nearly maximum activity from pH 8 to 11 and appears to be reduced to H(2)O(2).
PRODUCTION OF FREE INDOLE BY SOME AROIDS
TLDR
There is a close connection between the indole cycle and the production of heat and stench in the respiratory flare-up and some of the indoles formed is released as a constituent of the stench.
THE BIOSYNTHESIS OF INDOLEACETIC ACID IN MELAMPSORA LINI (PERS.) LEV.
TLDR
The results suggest that, in Melampsora, the synthesis of auxin, a radioactive and Ehrlich-positive product of tryptophane metabolism, is proposed.
Enzymatic Hydrolysis of Indoleacetonitrile
TLDR
Preliminary experiments led to the demonstration that a cell-free plant juice from Avena coleoptiles has this ability, and good agreement of the Salkowski indoleacetic acid determinations with results obtained from pea curvature and pea straight-growth bioassays, and with estimates from paper chromatograms.
Indole-3-ethanol Oxidase: Kinetics, Inhibition, and Regulation by Auxins.
TLDR
The results may be interpreted as showing that IAA is a noncompetitive inhibitor which binds to that conformation of the enzyme which also binds indoleethanol, and the significance of these interactions for the regulation of IAA biosynthesis is discussed.
Indole-3-acetic Acid Oxidase from Peas: I. Occurrence and Distribution of Peroxidative and Nonperoxidative Forms.
TLDR
The results indicate that nonperoxidative IAA oxidases might play a major role in the regulation of IAA content in pea seedlings.
