Special Issue Information

Dear Colleagues,

This Special Issue, “Plant Cell Wall Proteins and Development”, will cover a selection of recent research topics in the field of cell wall biology focused on cell wall proteins and their roles during development. Experimental papers, up-to-date review articles, and commentaries will be welcome.

Plant cell walls surround cells and provide both an external protection and a mean for cell-to-cell communication. They mainly comprise polymers like polysaccharides and lignin in lignified secondary walls and a minute amount of cell wall proteins (CWPs). CWPs are major players of cell wall remodeling and signaling. Cell wall proteomics, as well as numerous genetic or biochemical studies, have revealed the high diversity of CWPs, among which proteins acting on polysaccharides, proteases, oxido-reductases, lipid-related proteins and structural proteins. CWPs may have enzymatic activities such as cutting/ligating polymers or processing/degrading proteins. They may also contribute to the supra-molecular assembly of cell walls via protein/protein or protein/polysaccharide interactions. Thanks to these biochemical activities, they contribute to the dynamincs and the functionality of cell walls. Even though many researches have already been pursued to shed light on the many roles of CWPs, many functions still remain to be discovered especially for proteins identified in cell wall proteomes with yet unknown function.

The plant cell wall shows a great diversity regarding its chemical composition, which may vary significantly even during different developmental stages. In this study, we analysed the distribution of several cell wall epitopes in embryos of Brachypodium distachyon (Brachypodium). We also described the variations in the nucleus shape and the number of nucleoli that occurred in some embryo cells. The use of transmission electron microscopy, and histological and immunolocalisation techniques permitted the distribution of selected arabinogalactan proteins, extensins, pectins, and hemicelluloses on the embryo surface, internal cell compartments, and in the context of the cell wall ultrastructure to be demonstrated. We revealed that the majority of arabinogalactan proteins and extensins were distributed on the cell surface and that pectins were the main component of the seed coat and other parts, such as the mesocotyl cell walls and the radicula. Hemicelluloses were localised in the cell wall and outside of the radicula protodermis, respectively. The specific arrangement of those components may indicate their significance during embryo development and seed germination, thus suggesting the importance of their protective functions. Despite the differences in the cell wall composition, we found that some of the antibodies can be used as markers to identify specific cells and the parts of the developing Brachypodium embryo.

Title: Fascinating fasciclins: a surprisingly wide-spread protein family that mediates between the cell exterior and the cell surface

Abstract: The fasciclin 1 (Fas1) domain is an ancient structural motif found in extracellular proteins in all kingdoms of life and particularly abundant in plant genomes. Human Fas1 family members are associated with multiple aspects of health and disease. At the cellular level mammalian Fas1 proteins are associated with extracellular matrix structure, cell to extracellular matrix adhesion, paracrine signalling and endocytosis of proteoglycans. Mechanistically, mammalian Fas1 proteins interact with the integrin family of receptors and with both protein and carbohydrate components of the extracellular matrix. Fas1 proteins in plants have been implicated with a variety of biological functions including cellulosic and non-cellulosic cell wall structure and signalling with mechanisms of action gradually emerging. Less is known about the function of Fas1 proteins in fungi, eubacteria and archaea, however their differential presence in closely related organisms suggests their relevance for microbial life style including pathogenicity and symbiosis. The Fas1 domain accommodates multiple potential interaction surfaces enabling it to interact with both protein and carbohydrate interaction partners. The frequently observed tandem Fas1 arrangement might enable both co-operative and auto-inhibitory regulation of ligand binding. Additional protein domains and post-translational modifications are partially conserved between different evolutionary clades suggesting an ancient function of Fas1 cell surface proteins in cell to matrix adhesion. Collectively the comparison of different Fas1 proteins suggests a recurring role in the interaction between cells and their environment.

Title: Membrane-bound class III peroxidases: Overlooked enzymes with exciting functions
Authors: Sabine Lüthje and Teresa Martinez-Cortes
Abstract: Class III peroxidases are heme-containing peroxidases of the secretory pathway with a high redundance and versatile functions. In the past this peroxidase super family was belived as soluble proteins. Meanwhile class III peroxidases have been identified in tonoplast and plasma membranes of different plant tissues and species. In silico analysis revealed a membrane localization for about half of the class III peroxidases that are encoded by the maize (Zea mays) genome. Similar results has been found for other species like thale-cress (Arabidopsis thaliana) and rice (Oryza sativa). Although a function in membrane protection and/or membrane repair appear obvious, other functions have been suggested by in silico analysis and experimental data for some of these proteins. 

Title: Feeding the walls: how does nutrient availability regulate cell wall architecture?

Summary: The plant cell wall is largely composed of a complex array of polysaccharides and is essential for directed plant growth and for protection against biotic and abiotic stresses. Within the cell wall, cellulose strands form microfibrils, which act as a framework for deposition of other wall components, including hemicelluloses, pectins, proteins, and in some cases callose, lignin, and suberin. Cell wall architecture varies depending on cell and tissue type, and is governed by the targeted deposition, arrangement, and composition of cell wall components. Together, these different components largely determine the physical and structural properties of the cell wall, which in turn determines cell morphology and ultimately the shape of the whole plant. Nutrients are critical for proper plant development, and nutrient starvation severely affects plant growth and crop yield on a global scale. In response to nutrient starvation, plant growth is adapted through several different pathways, including changes in cell wall structure and composition. However, the underlying mechanisms that link nutrient availability to cell wall synthesis and thus plant architecture remain poorly understood. In this review, we aim to summarize current research on the adaptation of root cell walls in response to nutrient availability and the potential role of cell walls in nutrient sensing.

Abstract: Plant cell walls mostly comprise polysaccharides and proteins. The composition of monocots primary cell walls differ from that of dicots walls with respect to the type of hemicelluloses, the reduction of pectin abundance and the presence of aromatic molecules. Besides, cell wall proteins (CWPs) are also different among plant species. In addition, their distribution in functional classes varies according to cell types, organs developmental stages and/or environmental conditions. In this review, we go deeper into the findings of cell wall proteomics in monocot species and make a comparative analysis of the CWPs identified considering their predicted functions, the organs analyzed, the plant developmental stage and their possible use as targets for biofuel production. Arabidopsis thaliana CWPs were settled as a reference to allow comparisons among different monocots, i.e. Brachypodium distachyon, sugarcane and rice. Altogether, 1169 CWPs have been acknowledged, and specificities and similarities are discussed. In particular, a search for A. thaliana homologs of CWPs identified so far in monocots allows defining monocot specificities. Finally, the analysis of monocot CWPs appears as a powerful tool to identify candidate proteins of interest for tailoring cell walls to increase biomass yield of transformation for second generation fuels production.
