TLDR
Although many of the C-3 substituted indoles such as indole-3-acetic acid and tryptamine had colors in the reddish-violet-blue color region, most exhibited sufficient color differentiation to allow their identification by thin-layer chromatography.

Characterization of an Arabidopsis Enzyme Family That Conjugates Amino Acids to Indole-3-Acetic Acid

TL;DR: Evidence is established that several GH3 genes encode IAA-amido synthetases, which help to maintain auxin homeostasis by conjugating excess IAA to amino acids.
Journal ArticleDOI

Cadmium-tolerant plant growth-promoting bacteria associated with the roots of Indian mustard (Brassica juncea L. Czern.).

TL;DR: A positive correlation between the in vitro ACC deaminase activity of the bacteria and their stimulating effect on root elongation suggested that utilization of ACC is an important bacterial trait determining root growth promotion.
Journal ArticleDOI

Characterization of plant growth promoting rhizobacteria isolated from polluted soils and containing 1-aminocyclopropane-1-carboxylate deaminase.

TL;DR: The results suggest that plant growth promoting rhizobacteria containing ACC deaminase are present in various soils and offer promise as a bacterial inoculum for improvement of plant growth, particularly under unfavourable environmental conditions.
Journal ArticleDOI

In Posidonia oceanica cadmium induces changes in DNA methylation and chromatin patterning

TL;DR: The data demonstrate that Cd perturbs the DNA methylation status through the involvement of a specific methyltransferase, linked to nuclear chromatin reconfiguration likely to establish a new balance of expressed/repressed chromatin.
Journal ArticleDOI

Rhizobacterial mediation of plant hormone status

TL;DR: Combining rhizobacterial traits (or species) that impact on plant hormone status thereby modifying root architecture with traits that make additional resources available (e.g. nitrogen fixation, phosphate solubilisation) may enhance the sustainability of agriculture.

Colorimetric estimation of indoleacetic acid.

TL;DR: During a study of the inactivation of IAA in aqueous solutions, it was frequently necessary to assay at one time many samples where the IAA concentrations were low, or where the degree of significance of small differences in concentrations between experimental unite required evaluation, so it was desirable to re-examine the ferric chloride-sulphuric acid procedure.

Separation and detection of biogenic amines by thin-layer chromatography. Micro-analysis of tissue amines and of enzymes involved in their metabolism.

TL;DR: Simple and sensitive methods for the separation and detection of biogenic amines by thin-layer chromatography have been developed and adapted for microradiometric enzyme assays with a high degree of sensitivity and specificity.
Journal ArticleDOI

A Quantitative Estimation of Alkali-labile Indole-3-Acetic Acid Compounds in Dormant and Germinating Maize Kernels.

TL;DR: The total IAA content of corn kernels and intact seedlings decreases during germination, declining to about 10% of the original content during 96 hr of germination.
