Abstract: | Activities of polygalacturonase and 1,3-β-glucanase increased in campion (Silene vulgaris) callus cells during co-cultivation with the fungus Trichoderma harzianum. This was associated with a decrease in galacturonic acid residues in the pectic polysaccharide of campion silenan and also in the production of pectin by the callus. Co-cultivation of the callus and the fungus resulted in an increase in contents of arabinose residues in the intracellular arabinogalactan and in contents of galactose residues in the extracellular arabinogalactan. |
