Hlavní téma
About 450 million years ago fungal endophytes faciliated the establishment of plants on land. Today these fungi still support more than 80% of all plants. In harsh environments like high mountain systems, dark septate endopthytes are thought to replace arbuscular myrorrhizal fungi as the main endophytic partner of plants. The Bachelor student of this project should enjoy working on the microscope and be interested in how far the root colonization of Himalayan plants has been affected by climate change in the last 7 years.

Root-Colonization by Arbuscular Mycorrhizal Fungi and Dark Septate Endophytes in Himalayan Plants: A Comparison between 2015 and 2022
Climate change is an undeniable reality that impacts biological systems worldwide. As temperature rises, plant species are forced to adapt, extinct, or migrate to higher elevations. In harsh environments like the Himalayan mountains, fungi such as arbuscular mycorrhizal fungi (AMF) and dark septated endophytes (DSEs) support the majority of herbaceous plants by providing nutrients and protecting them from pathogens. This study evaluates root colonization rates of AMF and DSE in diverse plant species sampled from the Ladakh range in 2015 and 2022. Significant findings include a notable increase in AMF infection rates and a decrease in DSE colonization rates between these years. This is possibly linked to climate change-induced temperature rises and prolonged vegetation seasons. Furthermore, AMF were found to be abundant in such stressed environments. Additionally, deeper investigations into the roles of AMF and DSE in different plant species are needed for a more nuanced understanding of their ecological implications.

The head of the commission Prof Vácha welcomed the student Ms Moser, members of the committee, and guests. All committee members were present.
The student presented the theoretical background on fungi-plant symbiosis, Mycorrhiza and the specifics of Himalaya species, aims, methods used, and results.
The supervisor and the opponent presented their reviews and the student answered the questions and comments and further discussed various topics with the opponent.
Discussion with the commission members followed on the need for phosphorous in living organisms, the relation of mycorrhizae composition to the location and conditions, the relation of the studied phenotypes to specific fungi species, the frequency of the presence of boh AMF and DSE in the same plant sample, the heatmap production and other questions. The student answered all questions.
