Lignified cell walls are widely considered to be key innovations in the evolution of terrestrial plants from aquatic ancestors some 475 million years ago. Lignins, complex aromatic heteropolymers, stiffen and fortify secondary cell walls within xylem tissues, creating a dense matrix that binds cellulose microfibrils and crosslinks other wall components, thereby preventing the collapse of conductive vessels, lending biomechanical support to stems, and allowing plants to adopt an erect-growth… Expand
The cell wall polysaccharide metabolism of the brown alga Ectocarpus siliculosus. Insights into the evolution of extracellular matrix polysaccharides in Eukaryotes.
TLDR
Surprisingly, known families of cellulases, expansins and alginate lyases are absent in Ectocarpus, suggesting the existence of novel mechanisms and/or proteins for cell wall expansion in brown algae. Expand
The charophycean green algae provide insights into the early origins of plant cell walls.
TLDR
Members of the advanced charophycean green algae (CGA), including the Charales, Coleochaetales and Zygnematales, but not basal CGA (Klebsormidiales and Chlorokybales), have cell walls that are comparable in several respects to the primary walls of embryophytes. Expand
The evolution of hydrophobic cell wall biopolymers: from algae to angiosperms.
TLDR
Evidence is reviewed from extant members of the green plant clade (Chlorobionta) that the capacity to synthesize the monomeric precursors of all four biopolymers is ancestral and extends in some cases to unicellular plants (e.g. Chlamydomonas). Expand
Update on Plant and Algal Cell Wall Diversity Beyond the Green : Understanding the Evolutionary Puzzle of Plant and Algal Cell Walls 1
Niklas (2000) defined plants as “photosynthetic eukaryotes,” thereby including brown, red, and green macroalgae and microalgae. These groups share several features, including the presence of aExpand
A phenol-enriched cuticle is ancestral to lignin evolution in land plants
TLDR
A critical role for the ancestral phenolic metabolism in moss erect growth and cuticle permeability is demonstrated, consistent with importance in plant adaptation to terrestrial conditions. Expand
Evolution of the cell wall components during terrestrialization
TLDR
The current state of knowledge about some main components of the cell walls and their evolutionary alterations, as preadaptive features for the land colonization and the plant taxa diversification, is summarized and new surprising discoveries related to the composition of various cell walls are presented.

Future Perspectives in Plant Biology Understanding Lignification : Challenges Beyond Monolignol Biosynthesis 1
Lignin, a major component of vascular plant cell wall, provides mechanical support for plants to stand upright and enables xylems to withstand the negative pressure generated during water transport.Expand
Evolution and diversity of plant cell walls: from algae to flowering plants.
TLDR
In conclusion, organisms that have the shared features of photosynthesis and possession of a cell wall do not form a monophyletic group, yet they contain some common wall components that can be explained increasingly by genetic and biochemical evidence. Expand
Harnessing lignin evolution for biotechnological applications.
TLDR
The first true lignin was constructed via oxidative coupling of a number of simple phenylpropanoid alcohols to form a sturdy polymer that supports long-distance water transport. Expand
The origin and evolution of lignin biosynthesis.
TLDR
A number of aspects regarding the origin and evolution of lignin biosynthesis during land plant evolution are discussed, including the establishment of its monomer biosynthetic scaffold, potential precursors to the lIGNin polymer, as well as the emergence of the polymerization machinery and regulatory system.

Interrelation between Lignin Deposition and Polysaccharide Matrices during the Assembly of Plant Cell Walls
TLDR
The results suggest that such lignin substructures may be involved in the cohesion of secondary walls during cell wall biogenesis and the mutual influence of the cellulose-hemicellulose environment and monolignol local polymerization is discussed. Expand
Lignin-Like Compounds and Sporopollenin Coleochaete, an Algal Model for Land Plant Ancestry
TLDR
Investigation of resistant biopolymers in Coleochaete (Chlorophyta, class Charophyceae), a green alga on the evolutionary lineage that led to land plants, suggests a close relation between these taxa. Expand
Independent origins of syringyl lignin in vascular plants
TLDR
Gene expression data, cross-species complementation experiments, and in vitro enzyme assays indicate that this Selaginella F5H represents a new family of plant P450s and suggests that it has evolved independently of angiosperm F 5Hs. Expand
Biosynthesis and genetic engineering of lignin
TLDR
Progress in the knowledge of the lignin biosynthesis pathway has been obtained and it is now clear that the pathway is more complex than initially thought and there is evidence for alternative pathways. Expand
Evolution of xylem lignification and hydrogel transport regulation.
TLDR
The fine-scale patterning of lignin deposition in water-conducting cells is shown here to vary phylogenetically across vascular plants, suggesting that the evolutionary diversification of vascular cells thus reflects biochemical as well as morphological innovations evolved to fulfill opposing cell functions of transport and structural support. Expand
Collapsed xylem phenotype of Arabidopsis identifies mutants deficient in cellulose deposition in the secondary cell wall.
TLDR
Examination of the cell walls by using electron microscopy demonstrated that the decreases in cellulose content of irx lines resulted in an alteration of the spatial organization of cell wall material, suggesting that a normal pattern of cellulose deposition may be required for assembly of lignin or polysaccharides.

Structural motifs of syringyl peroxidases predate not only the gymnosperm-angiosperm divergence but also the radiation of tracheophytes.
TLDR
The findings showed that certain structural motifs characteristic of eudicot S-peroxidases predate the gymnosperm-angiosperm divergence and the radiation of tracheophytes, since they are found not only in peroxidase from basal gymnosperms, ferns and lycopods, but also in per oxidases from the moss Physcomitrella patens and the liverwort Marchantia polymorpha.

The lignin biosynthetic pathway has been studied for more than a century but has undergone major revisions over the past decade, presenting a current picture of monolignol biosynthesis, polymerization, and lignIn structure. Expand
