The effects of aluminum (Al) on root elongation, the mechanical extensibility of the cell wall, and the amount of cell-wall polysaccharides in the roots of Al-resistant (Atlas 66) and Al-sensitive (Scout 66) cultivars of wheat (Triticum aestivum L.) were examined. Exposure to 10 &mgr;M AlCl3 for 6 h inhibited root elongation in Scout 66 but not in Atlas 66. It also decreased the mechanical extensibility of the cell wall in the roots of both cultivars, but prominently only in the roots of Scout 66. The amount of hemicellulose in the 10-mm region of root apex of Scout 66 was increased by the exposure to Al, especially in the apical regions. Al did not influence the neutral sugar composition of either pectin or hemicellulose in Scout 66 roots. However, Al increased the weight-average molecular mass of hemicellulosic polysaccharides and the amounts of wall-bound ferulic and diferulic acids in Scout 66 roots. These findings suggest that Al modifies the metabolism of cell-wall components and thus makes the cell wall thick and rigid, thereby inhibiting the growth of wheat roots.

“…1aminocyclopropane-1-carboxylic acid (ACC) is the direct precursor of its synthesis (Saftner, 1992;Sarquis et al, 1992;Rothan and Nicolas, 1994). Every plant tissue may produce ethylene (Yu and Yang, 1980;Yang and Hoffman, 1984;Mattoo and White, 1991) but this production may also be indirectly induced by exogenous auxin (Blumenfeld, 1975;Bradford and Yang, 1980;Yoshii and Imaseki, 1981;Yeang and Hillman, 1982;Zimmerman andWilcoxon, 1935 apud Yang, 1987;Arteca et al, 1988;Smulders et al, 1990;Hoson et al, 1990;Kim et al, 1992).…”

Kohleria eriantha has rhizomes which are underground stems with buds enclosed by modified leaves, that store starch. The buds of this rhizome can develop in two morphological patterns: an aerial shoot (similar to the mother plant) or a rhizome, depending on the water level present in the substrate. Development of the shoot was inhibited by low water availability (1 mL) in the substrate. It was verified that ethylene and ABA were involved in controlling the development of the rhizome pattern under low water availability. Treatments with ethrel, PEG and ABA induced shoot development whereas treatments with AgNO3 or AVG inhibited shoot development. Increased ethylene and ABA were observed under conditions that inhibited shoot development. Moreover, it is suggested that ABA may induce the production of ethylene in the sections of the rhizome under low water availability.

Silicon confers aluminium tolerance in rice via cell wall modification in the root transition zone

The root‐apex transition zone (TZ), the major perception site for aluminium (Al) toxicity, is crucial for the Al‐induced root‐growth inhibition, while the mechanism underlying silicon‐mediated alleviation of Al toxicity in the TZ is largely unknown. In this study, the role of silicon (Si) in alleviating Al‐induced damage in the TZ and root‐growth inhibition of rice was investigated. We found that Si had direct alleviative effect on Al toxicity as revealed by less root growth‐inhibition, Al accumulation, and callose formation. Si reversed Al‐induced decreases of the cell wall elongation and extensibility, and reduced Al‐induced increments of cell wall polysaccharides in the TZ. The similar distribution patterns of Al and Si in the cell wall indicated that Si might detoxify Al by forming hydroxyaluminumsilicates in the apoplast of the root‐apex TZ. Moreover, the wall‐bound form of Si reduced Al binding sites, thereby reducing the capability of Al bound to the cell wall. These results suggest that Si‐mediated cell wall modification in the TZ alleviates Al‐induced root‐growth inhibition in rice involving the promotion of cell wall extensibility and the decrease of Al accumulation in the cell wall.
