Am 21. November findet der nächste Vortrag der P-Campus-Ringvorlesung WS 2024/25 statt. Prof. Dr. Katarzyna Hrynkiewicz von der Nicolaus Copernicus University in Toruń spricht online via Webex über den "Effect of mycorrhizal fungi on healthy and PVY-infected Solanum tuberosum L. plants".
Die Vorlesung beginnt um 15:00 Uhr und ist kostenfrei.
Abstract
Under natural conditions, crops interact with a variety of microorganisms. These include beneficial (symbiotic) and phytopathogenic microorganisms, which together affect plant growth and productivity. In recent decades, potato (Solanum tuberosum L.) production has been decreasing due to the prevalence of potato virus Y (PVY), which is one of the most important pests of the potato. Arbuscular mycorrhizal fungi (AMF) are common symbionts of potato, but the effect of mycorrhizal symbiosis on PVY disease development is poorly understood. Within the framework of two research projects on this issue, the effects of different AMFs on healthy and virus Y (PVY) infected potato were investigated. The analyses carried out included not only the measurement of potato growth parameters, but also indicators of oxidative stress and photosynthetic capacity. In addition, the development of AMF in plant roots was assessed, as well as the level of the virus in mycorrhizal plants. Studies have shown that there are multifactorial interactions in host plants colonized by phytopathogens and endophytes that are important for potato cultivation in agriculture.
