Journal ArticleDOI
Flavonoid Accumulation in Arabidopsis Repressed in Lignin Synthesis Affects Auxin Transport and Plant Growth
Sébastien Besseau,Laurent Hoffmann,Pierrette Geoffroy,Catherine Lapierre,Brigitte Pollet,Michel Legrand +5 more
TL;DR: Data demonstrate that the reduced size phenotype of HCT-silenced plants is not due to the alteration of lignin synthesis but to flavonoid accumulation, which is shown to be controlled by light and to depend on chalcone synthase expression.
Journal ArticleDOI
Silencing of hydroxycinnamoyl-coenzyme A shikimate/quinate hydroxycinnamoyltransferase affects phenylpropanoid biosynthesis.
Laurent Hoffmann,Seébastien Besseau,Pierrette Geoffroy,Christophe Ritzenthaler,Denise Meyer,Catherine Lapierre,Brigitte Pollet,Michel Legrand +7 more
TL;DR: The function of the acyltransferase in phenylpropanoid biosynthesis is demonstrated and a correlation between enzyme accumulation levels and lignin composition in vascular cells is shown.
Journal ArticleDOI
Polymeric proanthocyanidins are catabolized by human colonic microflora into low-molecular-weight phenolic acids.
Stéphanie Déprez,Christophe Brézillon,Sylvie Rabot,Catherine Philippe,Isabelle Mila,Catherine Lapierre,Augustin Scalbert +6 more
TL;DR: These results provide the first evidence of degradation of dietary phenolic polymers into low-molecular-weight aromatic compounds.
Journal ArticleDOI
Disruption of LACCASE4 and 17 Results in Tissue-Specific Alterations to Lignification of Arabidopsis thaliana Stems
Serge Berthet,Nathalie Demont-Caulet,Brigitte Pollet,Przemyslaw Bidzinski,Laurent Cézard,Phillipe Le Bris,Nero Borrega,Jonathan Hervé,Eddy Blondet,Sandrine Balzergue,Catherine Lapierre,Lise Jouanin +11 more
TL;DR: The findings suggest that the genetic engineering of lignin-specific laccases is a potentially innovative and promising tool for the fine-tuning of lIGNin content and structure.
Journal ArticleDOI
Lignin structure and its engineering
TL;DR: Examining lignins in different species reveals the extent to which evolution and natural variation have resulted in the incorporation of 'non-traditional' phenolic monomers, including phenolics from beyond the monolignol biosynthetic pathway.
