  • Identification of stress biomarkers for drought and increased soil temperature in seedlings of European beech (Fagus sylvatica)
    Popovic, Milica, gozdarstvo, 1982- ...
    Drought is an environmental stress that can drastically decrease plant productivity. Projections show both an increase in intense rain events and a reduction in the number of rain days, conditions ... that leads to increased risk of drought. Consequently, the identification of molecular biomarkers suitable for evaluating the impact of water deprivation conditions on forest plant seedlings would be of great importance for monitoring purposes and forest management. In this study we evaluated a biochemical methodology for the assessment of drought stress coupled to variable soil temperature in European beech (Fagus sylvatica L.) seedlings by analyzing a set of metabolites and enzymes involved in free radical scavenging and cell wall synthesis. The results indicate that the specific activities and isoform profile of superoxide dismutases and glutathione peroxidases together with the variation of phenolic compounds enable to discriminate between seedlings with different degree of photosynthetic activity. This approach represents a promising platform for the assessment of drought stress in forest trees and could serve for enhancing selection and breeding practices allowing for plants more tolerant of abiotic stress
