The dynamics of cell wall components during gall development are related to structural specialization to meet the defensive or nutritional requirements of gall tissues. Cell wall features have been studied mostly in galls induced by hemipterans (Psylloidea), while galls induced by Cecidomyiidae have been little explored. We applied monoclonal antibodies to epitopes of proteins and pectins in the cell walls of non-galled leaves and galls induced by Clinodiplosis sp. (Diptera; Cecidomyiidae) on Croton floribundus Spreng. (Euphorbiaceae). The complexity of tissue zonation in Clinodiplosis galls reflected the impairment of the activity of the pectin-methylesterases during development. The labeling of the epitopes of extensins in young galls denoted cell enlargement with resistant cell walls, while the labeling of epitopes of the arabinogalactan proteins in senescent galls indicated the involvement of these proteins with programmed cell death, at the end of cell cycles at the gall development site. We conclude that the cell wall profile in Clinodiplosis galls implies an imbalance between tissue porosity, cell-to-cell signaling, and resistance linked to tissue structural and functional compartments. Current data confirm the presence of the epitopes of extensins in young galls, and the compartmentalization of homogalacturonans and rhamnogalacturonan I in galls as an independent taxon feature.

ABSTRACT This review presents information on the relationship of ultrastructure and composition of wood cell walls, in order to understand how wood degrading bacteria utilise cell wall components for their nutrition. A brief outline of the structure and composition of plant cell walls and the degradation patterns associated with bacterial degradation of wood cell walls precedes the description of the relationship of cell wall micro- and ultrastructure to bacterial degradation of the cell wall. The main topics covered are cell wall structure and composition, patterns of cell wall degradation by erosion and tunnelling bacteria, and the relationship of cell wall ultrastructure and composition to wood degradation by erosion and tunnelling bacteria. Finally, pertinent information from select recent studies employing molecular approaches to identify bacteria which can degrade lignin and other wood cell wall components is presented, and prospects for future investigations on wood degrading bacteria are explored.

Abstract Background: Besides the use of maize grain as food and feed, maize stover can be a profitable by-product for cellulosic ethanol production, whereas the whole plant can be used in silage production. However, yield is reduced by pest damages, where stem corn borers are one of the most important factors limiting yield. Overall, cell wall composition is key in determining the quality of maize biomass, as well as pest resistance. This study aims to address the interrelations between cell wall components in diverse maize genotypes, and pest resistance, ethanolic production and forage digestibility. Results: We can highlight the following results: (i) pests resistant inbred lines may show cell walls with low p-coumaric acid and hemicellulose content; (ii) inbred lines showing cell walls with high cellulose content and diferulate cross-linking may present higher performance in ethanol production; (iii) and inbred lines with enhanced digestibility may have cell walls poor in neutral detergent fibre and diferulates, combined with a lignin polymer composition richer in G subunits. Conclusions: Our results evidence that there is no maize cell wall ideotype among the tested for optimal performance in the three areas evaluated, and maize plants should be specifically bred for each particular application.

Abstract Wood properties of furfurylation can be altered by reaction mechanisms of furfuryl alcohol polymer (PFA) and cell walls. Although chemical reactions between PFA and lignin have been studied, reaction mechanisms between PFA and cell wall components, including lignin, cellulose and hemicellulose are still not comprehensively understood. In order to elucidate chemical reactions regarding PFA with wood cell walls, model compounds of main cell wall components were used to investigate its reactions with PFA by 13C NMR spectroscopy and differential scanning calorimetry (DSC). Results showed that there was no chemical bonding of PFA with either cellulose or hemicellulose. Condensations of uncrowded ring positions (meta, ortho and para) and side chains (α–C, β–C, β–OH, and γ–OH) of lignin with PFA did occur based on 13C NMR spectra. Reaction enthalpy and activation energy also confirmed the condensation reactions between lignin and PFA. This study could provide design guidelines to control the chemical reactions of PFA in cell walls and lignin and, therefore, improve the properties of furfurylated wood.

<p>Colonization of terrestrial ecosystems by the first land plants, and their subsequent expansion and diversification, were crucial for the life on the Earth. However, our understanding of these processes is still relatively poor. Recent intensification of studies on various plant organisms have identified the plant cell walls are those structures, which played a key role in adaptive processes during the evolution of land plants. Cell wall as a structure protecting protoplasts and showing a high structural plasticity was one of the primary subjects to changes, giving plants the new properties and capabilities, which undoubtedly contributed to the evolutionary success of land plants.</p><p>In this paper, the current state of knowledge about some main components of the cell walls (cellulose, hemicelluloses, pectins and lignins) and their evolutionary alterations, as preadaptive features for the land colonization and the plant taxa diversification, is summarized. Some aspects related to the biosynthesis and modification of the cell wall components, with particular emphasis on the mechanism of transglycosylation, are also discussed. In addition, new surprising discoveries related to the composition of various cell walls, which change how we perceive their evolution, are presented, such as the presence of lignin in red algae or MLG (1→3),(1→4)-β-D-glucan in horsetails. Currently, several new and promising projects, regarding the cell wall, have started, deciphering its structure, composition and metabolism in the evolutionary context. That additional information will allow us to better understand the processes leading to the terrestrialization and the evolution of extant land plants.</p>

`Anna' and `Granny Smith' apples (Malus domestics Borkh.) that were held at 38C for 4 days before storage at 0C not only were firmer than controls upon removal from storage, but also softened more slowly during shelf life at 17C. Skin yellowing and loss of acidity attendant upon the heat treatment were not prevented by dipping fruit in 2% CaCl2 before heating. Both heat-treated and control fruit softened at the same rate upon exposure to ethylene at 100 μl·liter-1 upon removal from storage. The insoluble pectin content of cortical tissues was higher in heat-treated fruit than in controls after 10 days at 17C, while soluble pectin levels were lower. Arabinose and xylose levels were lower in cell walls from heat-treated cortical tissue, but the treatment had no effect on loss of galactose residues during shelf life.
