Developing fruit direct post-floral morphogenesis in Helleborus niger L.
TLDR
In fertilized flowers of Helleborus niger L., the sepals grow, spread, and turn green, and the peduncles elongate, but these processes did not proceed to completion when the pistils were removed at the bud stage, but could be restored by the application of plant growth regulators. Expand
Fruit initiation in Helleborus niger L. triggers chloroplast formation and photosynthesis in the perianth
TLDR
The metamorphosis of the sepals into photosynthetically active organs only occurs in fruit-bearing flowers and is arrested at a very early stage in controls in which the pistils are removed before pollination. Expand
Metabolism of exogenous auxin by Arabidopsis thaliana: Identification of the conjugate N‐(indol‐3‐ylacetyl)‐glutamine and initiation of a mutant screen
TLDR
Accumulation of the three amide conjugates was dramatically inhibited by cycloheximide, whereas accumulation of indole-3-acetyl-glucose was little affected, and a screen for Arabidopsis mutants altered in the IAA-inducible system for auxin conjugate formation was initiated. Expand
Noninvasive and continuous recordings of auxin fluxes in intact root apex with a carbon nanotube-modified and self-referencing microelectrode.
TLDR
New technology for the continuous measuring of IAA fluxes in living cells, tissues, and whole organs that is based on a carbon nanotube-modified and self-referencing microelectrode specific for IAA will advance knowledge of how IAA regulates plant development but will be applicable in medicine for its potential use in cancer therapy.

A Novel Auxin Conjugate Hydrolase from Wheat with Substrate Specificity for Longer Side-Chain Auxin Amide Conjugates1
TLDR
Temporal expression studies of TaIAR3 indicate that the transcript is initially expressed at day 1 after germination and Expression decreases through days 2, 5, 10, 15, and 20, and spatial expression studies found similar levels of expression throughout all wheat tissues examined. Expand
Isolation of novel indole-3-acetic acid conjugates by immunoaffinity extraction.
TLDR
To the authors' knowledge, the identification of IAA conjugates with Gly, Phe and Val from higher plants is reported here for the first time. Expand
Synthesis of 4,5,6,7 and 2,4,5,6,7 Deuterium-labeled Indole-3-Acetic Acid for Use in Mass Spectrometric Assays.
TLDR
The use of polydeutero internal standards separates the standards from the "isotope cluster" caused by the normal abundance of heavy isotopes and also permits use of reduced mass resolution, thus leading to a 10-fold increase in sensitivity. Expand
Molecular properties of 4-substituted indole-3-acetic acids affecting pea pericarp elongation
TLDR
The size of the 4-substituent, and its lipophilicity are associated with growth promoting activity of pea pericarp, while there was no obvious relationship with electromeric effects. Expand
Effect of halogen substitution of indole-3-acetic acid on biological activity in pea fruit
TLDR
This study is unique in that it reports the biological activity of 4-C1-IAA and halogen- IAA analogues in tissues of intact plants known to contain 3-chloroindole-3-acetic acid and 4- C1-iaA, and its possible importance in pea fruit growth. Expand
4-chloroindole-3-acetic and indole-3-acetic acids in Pisum sativum
TLDR
While, in young fruit tissues, IAA was more abundant than 4-C1-IAA, the opposite was true for seeds at the ‘table-ready’ stage and for roots of nine-day-old seedlings. Expand
