“…For example grapevine callus subjected to deficiency in S, N, and P showed walls with a decreased content in cellulose, increased lignin amount, alterations in the methylesterification of pectin (Fernandes et al, 2013). These results show how plant cell walls are remodeled in response to mineral deficits and how their composition is modified according to the stress condition applied.…”

Increasing industrialization and urbanization result in emission of pollutants in the environment including toxic heavy metals, as cadmium and lead. Among the different heavy metals contaminating the environment, cadmium raises great concern, as it is ecotoxic and as such can heavily impact ecosystems. The cell wall is the first structure of plant cells to come in contact with heavy metals. Its composition, characterized by proteins, polysaccharides and in some instances lignin and other phenolic compounds, confers the ability to bind non-covalently and/or covalently heavy metals via functional groups. A strong body of evidence in the literature has shown the role of the cell wall in heavy metal response: it sequesters heavy metals, but at the same time its synthesis and composition can be severely affected. The present review analyzes the dual property of plant cell walls, i.e., barrier and target of heavy metals, by taking Cd toxicity as example. Following a summary of the known physiological and biochemical responses of plants to Cd, the review compares the wall-related mechanisms in early- and later-diverging land plants, by considering the diversity in cell wall composition. By doing so, common as well as unique response mechanisms to metal/cadmium toxicity are identified among plant phyla and discussed. After discussing the role of hyperaccumulators’ cell walls as a particular case, the review concludes by considering important aspects for plant engineering.

“…They also found that P deficiency increased Al tolerance and decreased Al accumulation in rice roots. Although the mechanism is unknown, deficiency of P affects the cell wall composition (Fernandes et al 2013). For example, in Arabidopsis, P deficiency caused decreased concentrations of pectin and hemicellulose of the cell wall (Zhu et al 2012), although it is unknown whether similar changes occur in wheat.…”

Effect of in planta phosphorus on aluminum-induced inhibition of root elongation in wheat

Aims Both aluminum (Al) toxicity and phosphorus (P) deficiency are limiting factors of crop production on acid soils. Although Al-P interaction has been extensively studied, the results are controversial. The aim of this study is to investigate the effect of in planta P on Alinduced inhibition of root elongation in wheat (Triticum aestivum L.). Methods Roots of wheat (cv. Atlas 66) with different internal P concentrations were prepared by two methods; split-root and re-rooting in a hydroponic solution using three different P levels (0, 25 and 250 μM) to avoid direct precipitation of Al-P in the solution. Al toxicity was evaluated by root elongation inhibition and callose induction. The Al and P concentrations in the root tips were also compared among different treatments.Results Both split-root and re-rooting methods generated roots with different P concentrations in the tips when exposed to different P levels. Lower P in the root tips resulted in less Al-induced inhibition of the root elongation, less callose content and less Al accumulation, while higher root P caused a higher Al-induced inhibition of the root elongation, increased callose content and Al accumulation in the root tips. Furthermore, Al in the root cell sap was not altered by different P concentrations, but Al in the root cell wall was increased with increasing in planta P concentrations. Conclusions Al toxicity in wheat is associated with P in the root cell wall; lower root P enhanced Al tolerance, while higher root P aggravated Al toxicity in wheat.

“…110 During water stress, microtubules are eliminated by proteolytic degradation (Wang et al, 2011) followed by cellulose microfibril re-organization and activation of phospholipase-D dependent signaling during osmotic adaptation. [111][112][113] Release of DAMPs and CWI modifications can be perceived by membrane receptors, communicated by trans-membrane channels and can trigger internal cell signaling cascades to activate appropriate response genes. Thus, the large family of receptor like kinases (RLKs), arabinogalactan proteins, the Mitogen-Activated Protein Kinase (MAPK) pathway and the Target of Rapamycin (TOR) pathway have been suggested Figure 1.…”

The plant cell wall, a dynamic network of polysaccharides and glycoproteins of significant compositional and structural complexity, functions in plant growth, development and stress responses. in recent years, the existence of plant cell wall integrity (Cwi) maintenance mechanisms has been demonstrated, but little is known about the signaling pathways involved, or their components. examination of key mutants has shed light on the relationships between cell wall remodeling and plant cell responses, indicating a central role for the regulatory network that monitors and controls cell wall performance and integrity. in this review, we present a short overview of cell wall composition and discuss post-synthetic cell wall modification as a valuable approach for studying Cwi perception and signaling pathways.
