Chair of Plant Physiology

Research area:

• Molecular biosystematics – research on biological diversity and evolutionary relationships carried out on mosses (genus Racomitrium) and on higher plants (genus Viola) using molecular data, such as DNA, RNA, and protein sequences. It employs techniques like DNA sequencing, phylogenetic analysis, and molecular markers to classify organisms and infer their evolutionary history. It enhances traditional taxonomy by providing objective, quantifiable genetic information that helps resolve ambiguities in species identification and classification. Molecular biosystematics is widely used in conservation biology, ecology, and evolutionary research to understand genetic variation, speciation, and biodiversity patterns.
• Research on stress factors in plants – helps to understand how environmental and biotic stress, such as drought, salinity, extreme temperatures, and pathogens, affects plant growth and development. It explores physiological responses like changes in photosynthesis, water uptake, hormone regulation, and gene expression to understand plant adaptation and resilience mechanisms. Molecular, biochemical, and ecological approaches are used to identify stress-tolerance traits and improve plant resistance. This research is crucial for agriculture and ecosystem sustainability, helping to develop stress-resistant plant varieties and mitigate the effects of climate change on food production.

• Research topic concern the course of basic physiological processes in plants (photosynthesis, respiration, chlorophyll fluorescence, transpiration), concentration chlorophyll, antocyanins. Reactions of plants, mainly mosses (Polytrichum piliferum, Mnium undulatum), as well as ferns (Platycerium bifurcatum), and vascular plants (Oxalis acetosella, O. corniculata) on abiotic stress factors (excess and deficiency of solar radiation, hypoxia, anoxia, excess heavy metals, herbicides, salinity, changes in carbon dioxide concentration, drought stress, and low temperature).

Keywords: abiotic stress, gas exchange, chlorophyll fluorescence, mosses
