Lay Summary (English)

Lead
Lay summary
Treatment with necrotizing pathogens, colonization of roots with beneficial microorganisms or treatment of plants with various natural and synthetic compounds enhance the capacity of plants activating defense responses to biotic and abiotic stress - a process called priming. Priming has the advantage to have only a minor impact on the fitness of the plants compared to direct induction of a protected state and does therefore not significantly affect yield and other agricultural parameters. The priming process will be analysed in potato and compared to that found in the model plant Arabidopsis. Effects of priming on heat and drought tolerance of the plant as well as on tuberization, yield and quality of tubers will be investigated. A simple in vitro system will be developed to test the priming of heat and drought tolerance in potato by natural or synthetic compounds. The test system can be utilised in development of a new generation of bio-fertilizers that can enhance heat and drought tolerance of potato and increase the profitability of potato production in the Eastern European region.

Abstract

Treatment with necrotizing pathogens, colonization of roots with beneficial microorganisms or treatment of plants with various natural and synthetic compounds enhance capacity of plants activating defense responses to biotic and abiotic stress - a process called priming. This process will be analysed in potato and compared to that found in the model plant Arabidopsis. Effect of priming on heat and drought tolerance of the plant as well as on tuberization, yield and quality of tubers will be investigated. A simple in vitro system will be developed to test the priming of heat and drought tolerance in potato by natural or synthetic compounds. The test system can be utilised in development of a new generation of bio-fertilizers that can enhance heat and drought tolerance of potato and increase the profitability of potato production in the Eastern European region.
