An internal standard, [(13)C][indole-2]-indole-3-butyric acid, was synthesized from indole-2[(13)C] and was shown to be effective for the quantitative determination of indole-3-butyric acid from plant tissue. When this standard was used along with [(13)C(6)]indole-3-acetic acid, both indolic auxins could be quantified from the same tobacco (Nicotiana tabacam) leaf sample by isotope dilution ana...

Indole acetic acid complexes have been prepared and characterized by elemental analysis, H NMR and UVVisible spectra and electrochemical measurements. The antimicrobial properties of these compounds have been evaluated against the test strains (A.niger, St. aureusStreptococcus aureus) and thus a significant use of such compounds as antibacterial agent is reported. The biological activity data s...

A culture method was applied as factorial experiment based on completely randomized design using Filip 96-9L genotype of lentil + 0.25 mg L Indole butyric acid + different salt levels. Another was done to 1 identify the impact of the different hormone levels on Filip 92-12L genotype including: 0.9 mg L Indole acetic 1 acid + 0.2 mg L Kinetin, 1 and 2 mg L Indole acetic acid + 0.25 and 0.5 mg L ...

Cytokinin affects the requirement for auxin of a strain of tobacco callus (Nicotiana tabacum) which is cytokinin-autotrophic when grown on Murashige and Skoog medium with 11.4 mum of indole-3-acetic acid but requires cytokinin 6-(3-methyl-2-butenylamino)purine (i(6) Ade) when grown on the same medium with <3 mum indole-3-acetic acid. As the exogenous concentration of cytokinin (i(6) Ade) is inc...

In this study, the serum metabolic profiles of 10 female patients with restricting type anorexia nervosa (ANR) were compared to those age-matched healthy controls. While levels amino acids lower among than controls, uremic toxins, including p-cresyl sulfate (PCS), indole-3-acetic acid, and phenyl sulfate, higher in ANR patients. The PCS correlated positively abundance Clostridium coccoides grou...

The electrochemical behaviour of indole and a group of indole-containing compounds with a substituent at the C3 position, indol-3-acetamide (IAM), tryptamine, gramine, indole acetic acid (IAA), indole propionic acid (IPA), indole butyric acid (IBA) and tryptophan, was investigated at a glassy carbon electrode, in order to determine their oxidation pathways. Indole undergoes one irreversible pH ...

Nitrilases (nitrile aminohydrolase, EC 3.5.5.1) convert nitriles to carboxylic acids. We report the cloning, characterization, and expression patterns of four Arabidopsis thaliana nitrilase genes (NIT1-4), one of which was previously described [Bartling, D., Seedorf, M., Mithöfer, A. & Weiler, E. W. (1992) Eur. J. Biochem. 205, 417-424]. The nitrilase genes encode very similar proteins that hyd...

The symbiotic co-habitation of bacteria in the host colon is mutually beneficial to both partners. While the host provides the place and food for the bacteria to colonize and live, the bacteria in turn help the host in energy and nutritional homeostasis, development and maturation of the mucosal immune system, and protection against inflammation and carcinogenesis. In this review, we highlight ...
