Infection of lupin seedlings with Fusarium culmorum results in the increase in peroxidase activity with syringaldazine as a substrate, mostly in microsomes and cell walls, in the latter fraction somewhat later than in microsomes and cytosol. Less evident were the changes upon infection in peroxidase activity with guaiacol as a substrate. Both qualitative and quantitative differences in the peroxidase forms were evidenced on electrofocusing of the enzyme in the examined subcellular fractions.
