Lignin Biosynthesis and Structure
TL;DR: Lignin is the generic term for a large group of aromatic polymers resulting from the oxidative combinatorial coupling of 4-hydroxyphenylpropanoids, deposited predominantly in the walls of secondarily thickened cells, making them lignin-like polymers.
Journal ArticleDOI
MYB103 is required for FERULATE‐5‐HYDROXYLASE expression and syringyl lignin biosynthesis in Arabidopsis stems
David Öhman,Brecht Demedts,Brecht Demedts,Manoj Kumar,Lorenz Gerber,András Gorzsás,Geert Goeminne,Geert Goeminne,Mattias Hedenström,Brian E. Ellis,Wout Boerjan,Wout Boerjan,Björn Sundberg +12 more
TL;DR: It is demonstrated that F5H expression and hence biosynthesis of S lignin are dependent on MyB103, a direct transcriptional target of the transcription factor SECONDARY WALL ASSOCIATED NAC DOMAIN PROTEIN 1 (SND1), and 35S-driven dominant repression or over-expression of MYB103 modifies secondary wall thickness.
Journal ArticleDOI
Expression of SofLAC, a new laccase in sugarcane, restores lignin content but not S:G ratio of Arabidopsis lac17 mutant
Igor Cesarino,Igor Cesarino,Pedro Araújo,Juliana Lischka Sampaio Mayer,Renato Vicentini,Serge Berthet,Brecht Demedts,Bartel Vanholme,Wout Boerjan,Paulo Mazzafera +9 more
TL;DR: A combination of co-expression analysis, tissue/cell-type-specific expression analysis, and genetic complementation suggest that SofLAC participates in lignification in sugarcane.
Book ChapterDOI
Transient expression assays in tobacco protoplasts.
TL;DR: A transient expression assay in protoplasts derived from suspension cells of tobacco (Nicotiana tabacum) is described for the study of the transactivation capacities of transcription factors, allowing medium-throughput screening of interactions between large compendia of potential transcription factors and gene promoters.
