“…In bryophytes such as Sphagnum sp., Polytrichastrum formosum and P. patens , and the monilophytes like Equisetum arvense, Dryopteris filix-mas and Pteridium aquilinum , the typical type-II arabinogalactan linkages found in AGPs were detected (t-Ara f , 4-GlcA p , 3-Gal p , 3,6-Gal p ). However, unusual sugars were also analyzed such as a terminal 3- O -methyl-L-Rha in ferns and mosses which has not been found in angiosperms so far (Fu et al, 2007; Moller et al, 2007; Bartels and Classen, 2017), or even 1,2,3-linked Gal residues never described before in AGPs (Bartels and Classen, 2017). Interestingly, in the lycophytes like Lycopodium annotinum , the terminal 3- O -methyl-L-Rha was not detected.…”

Evolution of Cell Wall Polymers in Tip-Growing Land Plant Gametophytes: Composition, Distribution, Functional Aspects and Their Remodeling

et al. 2019

During evolution of land plants, the first colonizing species presented leafy-dominant gametophytes, found in non-vascular plants (bryophytes). Today, bryophytes include liverworts, mosses, and hornworts. In the first seedless vascular plants (lycophytes), the sporophytic stage of life started to be predominant. In the seed producing plants, gymnosperms and angiosperms , the gametophytic stage is restricted to reproduction. In mosses and ferns, the haploid spores germinate and form a protonema, which develops into a leafy gametophyte producing rhizoids for anchorage, water and nutrient uptakes. The basal gymnosperms (cycads and Ginkgo ) reproduce by zooidogamy. Their pollen grains develop a multi-branched pollen tube that penetrates the nucellus and releases flagellated sperm cells that swim to the egg cell. The pollen grain of other gymnosperms (conifers and gnetophytes) as well as angiosperms germinates and produces a pollen tube that directly delivers the sperm cells to the ovule (siphonogamy). These different gametophytes, which are short or long-lived structures, share a common tip-growing mode of cell expansion. Tip-growth requires a massive cell wall deposition to promote cell elongation, but also a tight spatial and temporal control of the cell wall remodeling in order to modulate the mechanical properties of the cell wall. The growth rate of these cells is very variable depending on the structure and the species, ranging from very slow (protonemata, rhizoids, and some gymnosperm pollen tubes), to a slow to fast-growth in other gymnosperms and angiosperms. In addition, the structural diversity of the female counterparts in angiosperms (dry, semi-dry vs wet stigmas, short vs long, solid vs hollow styles) will impact the speed and efficiency of sperm delivery. As the evolution and diversity of the cell wall polysaccharides accompanied the diversification of cell wall structural proteins and remodeling enzymes, this review focuses on our current knowledge on the biochemistry, the distribution and remodeling of the main cell wall polymers (including cellulose, hemicelluloses, pectins, callose, arabinogalactan-proteins and extensins), during the tip-expansion of gametophytes from bryophytes, pteridophytes (lycophytes and monilophytes), gymnosperms and the monocot and eudicot angiosperms.

“…Some studies have determined that cell wall composition differs among plants belonging to different phylogenetic groups (Popper and Fry 2004, Sørensen et al 2010, Popper et al 2011, Bartels and Classen 2017. Additionally, several studies have characterized cell wall composition changes in different monocot and dicot species under stressing conditions (see, for instance, Sweet et al 1990, Vicré et al 1999Leucci et al 2008, Moore et al 2008, Solecka et al 2008, Suwa et al 2010, Carvalho et al 2013, Baldwin et al 2014, Zheng et al 2014, Clemente-Moreno et al 2019, Roig-Oliver et al 2020.…”

Cell wall thickness (Tcw) determines photosynthesis and leaf elasticity. However, only a few studies in angiosperms addressed cell wall composition implication in regulating photosynthesis and leaf water relations through mesophyll conductance (gm) and bulk modulus of elasticity (ε) adjustments, respectively. Thus, we compared the phylogenetically distant Ginkgo biloba L. and Helianthus annuus L. under control and water deprivation to study the relationship between changes in cell wall composition (cellulose, hemicelluloses, and pectins) with gm and ε. Although no changes were found for Tcw, both species differently modified cell wall composition, resulting in different physiological consequences. H. annuus increased cellulose, hemicelluloses, and pectins in a similar proportion, maintaining ε. Additionally, it reduced photosynthesis due to stomatal closure. G. biloba did not decrease photosynthesis and largely increased hemicelluloses, leaf mass area, and leaf density, enhancing ε. Nonetheless, no association between cell wall composition and gm was found in either of the two species.

“…AGPs represent a diverse group of highly glycosylated proteins that are found in the cell wall, the apoplastic space and/or the medium surrounding plant cell. They are widely distributed throughout the major taxa of land plants (Šamaj et al, 1999b; Bartels and Classen, 2017; Bartels et al, 2017; Johnson et al, 2017b; Ma et al, 2017). AGPs belong to a large group of hydroxyproline (hyp)-containing proteins and possess a protein backbone consisting of repeating subunits that contain hyp/proline (pro), alanine (ala), and serine (ser)/threonine (thr) (Johnson et al, 2003, 2017a,b; Lamport et al, 2014, 2018; Herve et al, 2016; Bartels et al, 2017).…”

Arabinogalactan Proteins and the Extracellular Matrix of Charophytes: A Sticky Business

et al. 2019

Charophytes represent the group of green algae whose ancestors invaded land and ultimately gave rise to land plants 450 million years ago. While Zygnematophyceae are believed to be the direct sister lineage to embryophytes, different members of this group ( Penium , Spirogyra , Zygnema ) and the advanced thallus forming Coleochaete as well as the sarcinoid basal streptophyte Chlorokybus were investigated concerning their vegetative extracellular matrix (ECM) properties. Many taxa exhibit adhesion phenomena that are critical for affixing to a substrate or keeping cells together in a thallus, however, there is a great variety in possible reactions to e.g., wounding. In this study an analysis of adhesion mechanisms revealed that arabinogalactan proteins (AGPs) are most likely key adhesion molecules. Through use of monoclonal antibodies (JIM13) or the Yariv reagent, AGPs were located in cell surface sheaths and cell walls that were parts of the adhesion focal zones on substrates including wound induced rhizoid formation. JIM5, detecting highly methyl-esterfied homoglacturonan and JIM8, an antibody detecting AGP glycan and LM6 detecting arabinans were also tested and a colocalization was found in several examples (e.g., Zygnema ) suggesting an interplay between these components. AGPs have been described in this study to perform both, cell to cell adhesion in algae forming thalli and cell to surface adhesion in the filamentous forms. These findings enable a broader evolutionary understanding of the function of AGPs in charophyte green algae.
