3‐Methyl‐1‐Butanol Enhances Postharvest Resistance of Red Grapes to Botrytis cinerea by Activating Phenylpropanoid Metabolism and Antioxidant Defences

Plant Biotechnology Journal, EarlyView.
ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).

THE IMPORTANCE OF DIET THERAPY IN THE TREATMENT OF PHENYLKETONURIA: A CASE REPORT

Elektronički Zbornik Radova Veleučilišta u Šibeniku, 2022
Phenylketonuria is the most common inborn error of amino acid metabolism. It is caused by the impossibility of converting the essential amino acid phenylalanine into tyrosine, most often due to insufficient production or a complete lack of the enzyme ...

Phenylalanine iminoboronates as new phenylalanine hydroxylase modulators

RSC Adv., 2014
Herein we report the discovery of new modulators of human phenylalanine hydroxylase (hPAH) inspired by the structure of its substrate and regulatorl-phenylalanine.

Chronic Immune Stimulation May Cause Moderate Impairment of Phenylalanine 4-hydroxylase

Pteridines, 2011
Phenylalanine (4)-hydroxylase (PAH, E.C. 1.14.16.1) is located mainly in liver and converts amino acid phenylalanine (Phe) to tyrosine (Tyr). In 'classical' phenylketonuria (PKU), PAH activity is reduced, whereas in 'atypical' PKU biosynthesis of the ...

Mechanism of phenylalanine regulation of phenylalanine hydroxylase.

Journal of Biological Chemistry, 1990
The mechanism of phenylalanine regulation of rat liver phenylalanine hydroxylase was studied. We show that phenylalanine "activates" phenylalanine hydroxylase, converting it from an inactive to active form, by binding at a true allosteric regulatory site.

Molecular analysis of the early interaction between the grapevine flower and Botrytis cinerea reveals that prompt activation of specific host pathways leads to fungus quiescence [PDF]

, 2017
Grape quality and yield can be impaired by bunch rot, caused by the necrotrophic fungus Botrytis cinerea. Infection often occurs at flowering, and the pathogen stays quiescent until fruit maturity.

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

Plant Biotechnology Journal, EarlyView.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.

Identification and characterization of the PhhR regulon in Pseudomonas putida [PDF]

, 2010
Pseudomonas putida is a soil microorganism that utilizes aromatic amino acids present in root exudates as a nitrogen source. We have previously shown that the PhhR transcriptional regulator induces phhAB genes encoding a phenylalanine hydroxylase.
