TL;DR: It is demonstrated that guaiacyl and syringyl lignin subunits are largely dispensable for normal growth and development, and it is suggested that the transcription machinery and signalling pathways responding to cell wall defects may be important targets to include in efforts to reduce biomass recalcitrance.

TL;DR: Data support the contention that the C-lignin polymer is produced in vivo via combinatorial oxidative radical coupling that is under simple chemical control, a mechanism analogous to that theorized for classical lignin biosynthesis.

TL;DR: The data support a model of protoxylem TE lignification in which monolignols are highly mobile once exported to the cell wall, and in which precise targeting of laccases to secondary cell wall domains directs lignin deposition.

TL;DR: C-lignin, which is essentially a benzodioxane homopolymer without condensed units, might represent an ideal lignin for valorization, as it circumvents these issues and is highly acid-resistant.

TL;DR: Recent studies have begun to identify specific laccase and peroxidase proteins responsible for lignin polymerization in specific cell types and during different developmental stages, suggesting the coordination of polymerization machinery localization and monolignol supply is likely critical for the spatio-temporal patterning of lignIn polymerization.
