Special Issue Information

Dear Colleagues,

Plant cell wall, a complex structure that surrounds and protects the cell, is highly dynamic during plant development and in response to stress; both its composition and structure change in response to internal and external stimuli. The composition of polysaccharide varies between cell types, tissues, and developmental stages. Proteins with different functions, differentially present in cell walls, are involved in its structure regulation. Enzymes and their inhibitors promote changes in the interaction between polysaccharides by changing their chemical properties. The plant cell wall is also involved in cell–cell signaling. Receptor proteins, channels, and proteins involved in plasmodesmata function are present in the plant cell wall.

Studies on the role of the plant cell wall during development and in response to stress were conducted in different plant species. In Arabidopsis and other model plants, the use loss or gain of function mutants of CWP provided important information about the role of the cell wall in many developmental processes such as seed germination, hypocotyls elongation, flowering, fruit development, etc., and in response to different stresses. In non-model plants, for example, the role of pectins on bud dormancy was studied using inmmunocytochemical tools.

This Special Issue is dedicated to recent studies and reviews on the role of the plant cell wall during development and in stress responses at cell and whole plant level. Contributions featuring studies in different model and non-model plant species are welcomed.

The exogenous application of ethylene or 1-aminocyclopropane-1-carboxylic acid (ACC), the biosynthetic precursor for ethylene, to plants decreases the capacity of the cell wall to extend, thereby inhibiting stem elongation. In this study, the mechanism by which the extensibility of cell walls decreases in ACC-treated azuki bean epicotyls was studied. ACC decreased the total extensibility of cell walls, and such a decrease was due to the decrease in irreversible extensibility. ACC increased the molecular mass of xyloglucans but decreased the activity of xyloglucan-degrading enzymes. The expression of VaXTHS4, which only exhibits hydrolase activity toward xyloglucans, was downregulated by ACC treatment, whereas that of VaXTH1 or VaXTH2, which exhibits only transglucosylase activity toward xyloglucans, was not affected by ACC treatment. The suppression of xyloglucan-degrading activity by downregulating VaXTHS4 expression may be responsible for the increase in the molecular mass of xyloglucan. Our results suggest that the modification of xyloglucan metabolism is necessary to decrease cell wall extensibility, thereby inhibiting the elongation growth of epicotyls in ACC-treated azuki bean seedlings.

Plant cell wall remodeling is an important process during plant responses to heat stress. Pectins, a group of cell wall polysaccharides with a great diversity of complex chemical structures, are also involved in heat stress responses. Enzymatic activity of the pectin methyl esterases, which remove methyl groups from pectins in the cell wall, is regulated by DUF642 proteins, as described in different plants, including Arabidopsis thaliana and Oryza sativa. Our results demonstrated that heat stress altered the expression of the DUF642 gene, BIIDXI. There was an important decrease in BIIDXI expression during the first hour of HS, followed by an increase at 24 h. bdx-1 seedlings had less tolerance to heat stress but presented a normal heat stress response; HSFA2 and HSP22 expressions were highly increased, as they were in WT seedlings. Thermopriming triggered changes in pectin methyl esterase activity in WT seedlings, while no increases in PME activity were detected in bdx-1 seedlings at the same conditions. Taken together, our results suggest that BIIDXI is involved in thermotolerance via PME activation. Full article

Aluminum (Al) is an important element in soil constitution. Previous studies have shown that high concentration of Al affects the normal growth of crops, resulting in crop yield reduction and inferior quality. Nevertheless, Al has also been referred to as a beneficial element, especially when used at low concentrations, but the cytological mechanism is not clear. Influences of low concentration AlCl3 on the pollen tube growth of apple (Malus domestica) and its possible cytological mechanism were investigated in this study. The results showed that 20 μM AlCl3 promoted pollen germination and tube elongation; 20 μM AlCl3 enhanced Ca2+ influx but did not affect [Ca2+]c of the pollen tube tip; and 20 μM AlCl3 decreased acid pectins in pollen tubes but increased esterified pectins and arabinan pectins in pollen tubes. According to the information provided in this research, 20 μM AlCl3 stimulated growth of pollen tubes by enhancing Ca2+ influx and changing cell wall components. Full article
