Nitrogen‐Centered Organic Persistent Radicals Catalyze Redox‐Neutral C─C Bond Forming Reactions

open access: yesAngewandte Chemie, EarlyView.
Kuhn verdazyls, discovered over 60 years ago, are shown as effective catalysts for the first time. Their tunable redox properties enable organocatalytic redox‐neutral C─H arylation and C─H trifluoromethylation reactions without light activation.

Hormonal Status of Transgenic Birch with a Pine Glutamine Synthetase Gene during Rooting In Vitro and Budburst Outdoors

open access: yesBiomolecules, 2023
Improving nitrogen use efficiency (NUE) is one of the main ways of increasing plant productivity through genetic engineering. The modification of nitrogen (N) metabolism can affect the hormonal content, but in transgenic plants, this aspect has not been ...

Biological Activity of Vegetal Extracts Containing Phenols on Plant Metabolism

open access: yesMolecules, 2016
The influence of vegetal extracts derived from red grape, blueberry fruits and hawthorn leaves on Zea mays L. plant growth and the activity of phenylalanine ammonia-lyase (PAL), a key enzyme of the phenylpropanoid pathway, was investigated in laboratory ...

Promotion of Indoleacetic Acid Oxidase Isoenzymes in Tobacco Callus Cultures by Indoleacetic Acid [PDF]

open access: yesPlant Physiology, 1971
Indoleacetic acid oxidase in tobacco callus cultures (Nicotiana tabacum L., cv. White Gold) was composed of at least two groups of isoenzymes, which were distinctly different in electrophoretic mobilities and in responses to growth substances. Indoleacetic acid had dual effects; at low concentrations it promoted the development of two fast-migrating ...

Formation of indoleacetic acid by intestinal anaerobes [PDF]

open access: yesJournal of Bacteriology, 1975
Indoleacetic acid was produced from tryptophan by only three of 23 intestinal anaerobes studied. Evidence is presented to show that the formation of indoleacetic acid proceeds through the intermediate, indolepyruvic acid, via transamination with alpha-ketoglutarate rather than by tryptamine pathway.
