“…Pectins are high-molecular carbohydrates with d -galacturonic acid as their main structural component of that are found in the tissues of terrestrial plants and in some algae. In some plant tissues, for example in the white part of a citrus peel, the pectin content may reach up to 30% of dry weight, while, in others, it does not exceed a fraction of a percent [ 31 , 32 ]. Grasses, which contain a type II cell wall, are generally pectin poor [ 33 ].…”

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.

“…Grasses are considered as generally pectin‐poor plants (Carpita et al, 2001; Szatanik‐Kloc, Szerement, & Jozefaciuk, 2017), as grasses contain a type II cell wall. Pectins have also been detected in walls of the phloem cells of some Poaceae species, but there is still lack of knowledge about the functions of varied pectic epitopes, including xyloglucans, in monocot plants.…”

Cell wall epitopes in grasses of different novel ecosystem habitats on post‐industrial sites

et al. 2020

The post‐industrial habitats provide previously unknown conditions for plant and vegetation development. We asked the question: do the extreme soil substrate conditions cause differences in chemical composition of cell walls of leaves in three grass species: Calamagrostis epigejos (L.) Roth, Phragmites australis (Cav.) Trin. ex Steud, and Molinia caerulea (L.) Moench? With the use of immunohistochemical methods we determined the spatial distribution of selected pectic and AGP (arabinogalactan proteins) epitopes within leaf tissues of grass species growing in two industrial and control (meadow) habitats. Some post‐industrial habitats increase biodiversity. Fast adaptation and divergence cause phenotypic changes. This process has been recently recorded and is called human‐induced rapid evolutionary changes. The levels of pectins and arabinogalactan proteins increased on the post‐industrial habitats in comparison to the control sites. On control habitat, pectic epitope with galactan chain residues (recognised by the LM5 antibody) was not detected in cell walls of Calamagrostis epigejos leaves, but was abundantly present in Phragmites australis leaves. The pectic epitope with arabinan residues (recognized by LM6 antibody) was less represented in cell walls of Molinia caerulea leaves. AGP epitope, recognised by LM2 antibody, was abundant only in Ph. australis. In Molinia caerulea this epitope was not detected. The AGP epitope recognised by JIM13 antibody was observed in all analysed species. The results obtained revealed the response of grass individuals to different environments: a) varied responses to different soil substratum conditions (novel ecosystems), and b) that this reaction is species‐specific with respect to the analysed cell wall components.

“…The electric charge is most frequently studied root surface property to describe the root CEC, its changes with soil pH, balance of plant cations of different valence and toxicity of trace metals. Electric charge of the root compartments is dominated by negatively charged groups, thus positively charged cations, including essential nutrients, accumulate near the roots surface [50]. In our study we have noticed a positive effect of intensive S nutrition of Ni-exposed plants on the studied properties of roots (Q tot and CEC), especially at 6 mM S. The beneficial effect of extra S supply of Ni-treated mustard on the changes in the studied root properties may contribute to a better uptake of micronutrients and thus positively affect the mineral status of plants, which consequently stimulates their growth.…”

“…The values of CEC under differentiated experimental conditions were determined using potentiometric titration described in detail by Szatanik-Kloc et al [50]. In brief, the fresh roots were placed in a ventilated room at 30 °C for 48 h. Then, a suspension of plant roots equilibrated overnight with 1 M L −1 NaCl was adjusted to pH = 3.0 until the pH was stable over the next 5 min and titrated automatically (Titrino 702 MS, Metrohm AG, Switzerland) by 60 s increments of 1 μL 0.100 M L −1 sodium hydroxide solution to pH = 10.…”

An efficient method of improving the micronutrient status of Ni-treated white mustard (Sinapis alba L.) using intensive S-SO4 nutrition was developed. Twelve variants of Hoagland’s nutrient solution differing in the concentration of S-SO4 (standard: 2 mM S, and elevated level: 6 or 9 mM S) and Ni (0, 0.0004, 0.04, or 0.08 mM Ni) were tested. The beneficial effect of intensive S nutrition on Ni-stressed plants was manifested by a significant rise in the content of Fe, Mn, and Zn, especially in the shoots. An increase was also found in the shoot B, Cu, and Mo content, whilst there were no changes in their root concentrations. Simultaneously, the shoot Cl concentrations dropped. The elevated level of S in the nutrient solution in general enhanced the translocation of Fe, Cu, Mo, and B in Ni-exposed plants. The beneficial effect of intensive S nutrition on the growth and micronutrient balance of Ni-exposed plants can be at least partially related to the positive changes in root surface properties, especially in cation exchange capacity (CEC). Meanwhile both reduced glutathione (GSH) and phytochelatins (PCs) probably do not significantly contribute to Ni resistance of white mustard under intensive S nutrition.
