The isolation and mapping of a novel hydroxycinnamoyltransferase in the globe artichoke chlorogenic acid pathway

BMC Plant Biology, 2009
Background The leaves of globe artichoke and cultivated cardoon (Cynara cardunculus L.) have significant pharmaceutical properties, which mainly result from their high content of polyphenolic compounds such as monocaffeoylquinic and dicaffeoylquinic acid

Unusual ancestry of dehydratases associated with quinate catabolism in Acinetobacter calcoaceticus [PDF]

Journal of Bacteriology, 1995
Catabolism of quinate to protocatechuate requires the consecutive action of quinate dehydrogenase (QuiA), dehydroquinate dehydratase (QuiB), and dehydroshikimate dehyratase (QuiC), Genes for catabolism of protocatechuate are encoded by the pca operon in the Acinetobacter calcoaceticus chromosome.

Isolation and functional characterization of a cDNA coding a hydroxycinnamoyltransferase involved in phenylpropanoid biosynthesis in Cynara cardunculus L

BMC Plant Biology, 2007
Background Cynara cardunculus L. is an edible plant of pharmaceutical interest, in particular with respect to the polyphenolic content of its leaves. It includes three taxa: globe artichoke, cultivated cardoon, and wild cardoon.

The involvement of phenolic metabolism in superficial scald development in ‘Wujiuxiang’ pear

Journal of Applied Botany and Food Quality, 2020
Superficial scald often occurs after a long term of cold storage in apples and pears. In this study, the superficial scald index, the contents of major phenolic compounds, polyphenol oxidase (PPO) activity and its related genes expression in peel was ...

Maternal Metabolome in Pregnancy and Childhood Asthma or Recurrent Wheeze in the Vitamin D Antenatal Asthma Reduction Trial

Metabolites, 2021
The in utero environment during pregnancy has important implications for the developing health of the child. We aim to examine the potential impact of maternal metabolome at two different timepoints in pregnancy on offspring respiratory health in early ...

Purification and Characterization of Membrane-bound Quinoprotein Quinate Dehydrogenase

Bioscience, Biotechnology, and Biochemistry, 2003
Several bacterial strains carrying quinoprotein quinate dehydrogenase (QDH) were screened through acetic acid bacteria and other bacteria. Strong enzyme activity was found in the membrane fraction of Gluconobacter melanogenus IFO 3294, G. oxydans IFO 3292, G. oxydans IFO 3244, and some strains of Acinetobacter calcoaceticus.

Metabolomic Analysis Reveals Structural Diversity of Pectic Polysaccharides From Prunus persica (L.) Batsch and Their Relationship With Purees Characteristics

Plant Biotechnology Journal, EarlyView.
ABSTRACT To clarify how pectin heterogeneity relates to puree quality, this study investigated associations among pectin fractions, metabolite profiles, and physicochemical properties of peach purees from 20 cultivars with distinct viscosity, turbidity, and colour.

Ectopic expression of the Osmyb4 rice gene enhances synthesis of hydroxycinnamic acid derivatives in tobacco and clary sage

Biologia Plantarum, 2013
In this work, we report the ectopic expression of the Osmyb4 rice gene, encoding the Myb4 transcription factor, in Nicotiana tabacum and Salvia sclarea.

Genome-wide transcriptional profiling of appressorium development by the rice blast fungus Magnaporthe oryzae. [PDF]

PLoS Pathogens, 2012
The rice blast fungus Magnaporthe oryzae is one of the most significant pathogens affecting global food security. To cause rice blast disease the fungus elaborates a specialised infection structure called an appressorium.

Differential flux through the quinate and shikimate pathways. Implications for the channelling hypothesis [PDF]

Biochemical Journal, 1992
The qutC gene encoding dehydroshikimate dehydratase has been constitutively overexpressed in Aspergillus nidulans from a range of 1-30-fold over the normal wild-type level. This overexpression leads to impaired growth in minimal medium which can be alleviated by the addition of aromatic amino acids to the medium.
