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.
KEY WORDS: callus, Trichoderma harzianum, Silene vulgaris, enzymes, pectic polysaccharides, silenan
