Sažetak
Chestnut blight disease, caused by an introduced pathogenic fungus Cryphonectria parasitica, is responsible for serious dieback of sweet chestnuts in forest ecosystems. Biological control is highly desirable protection measure against plant diseases. Cryphonectria hypovirus 1 (CHV1) is an RNA mycovirus that by infecting C. parasitica reduces its virulence and may act as biocontrol agent of the chestnut blight. Previously it was shown that infection with CHV1 causes oxidative stress in C. parasitica and changes the activities of stress-related enzymes in laboratory cultures. The aim of this study was to determine the expected range of the oxidative stress enzyme activities in CHV1-infected fungal isolates from two chestnut blight populations naturally infected with the aforementioned virus. The level of lipid peroxidation, the content of non-protein thiols and the activity of glutathione S-transferase was measured in 10 samples from population Ozalj and 9 samples from population Kast. While the activity of glutathione S-transferase did not show any difference between CHV1-infected isolates of chestnut blight fungus from two populations, the level of lipid peroxidation and the content of non-protein thiols were significantly different between the two analyzed populations. This induced change in the oxidative stress parameters may be caused by previously determined intra-host CHV1 genetic diversity between these two populations. Alternatively, genetic differences of fungal isolates between Ozalj and Kast might also provide an explanation for variability of the response to the infection between isolates from these two populations.
