Possible Involvement of Cell Wall Pectic Polysaccharides in Aluminum Resistance of Some Plant Species
The role of cell wall pectin in aluminum resistance was investigated in some plant species. The amount of Al absorbed to cell walls of wheat was decreased by pectinase treatment. While oxalate efflux couldnt explain genotypic Al differences between Al-resistant and Al-sensitive buckwheat cultivars, we found that cell wall pectin was substantially higher in the Al-sensitive cultivars. We further found that cell wall pectin properties showed some correlations with root tip Al content and different Al resistance in two rice cultivars. All these results indicate that cell wall pectin may play an important role in plant Al resistance.
