I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbivores. Additionally, I tested the role of PSF in relation to plant population structure and the significance of soil legacy effects in natural conditions. The findings reveal that temporal dynamics in PSF are driven by changes in plant sensitivity and in the soil microbiome. Although bacteria isolated from J. vulgaris roots can negatively affect plant performance, they can also affect aboveground herbivores and other plant species. Consequently, these bacteria may not be suitable for biological control of J. vulgaris. Moreover, I discovered that soil nematodes can mediate plant-plant interactions, but often favoring J. vulgaris. In my field work, I detected soil legacy effects, but seedling recruitment spatial patterns of J. vulgaris were not soil-mediated. The insights gained from studying PSF and above- and belowground interactions have the potential to reshape traditional approaches employed in controlling invasive plants. This thesis emphasizes the importance of transitioning PSF experiments from indoor to outdoor settings considering various influencing factors simultaneously. Show less

Show moreSunitinib has been approved by FDA in 2006 and became the first-line treatment for patients with clear cell metastatic renal cell carcinoma (cc-mRCC) due to its dramatic improvement in progression-free survival (PFS) and overall survival (OS) and affordable toxicity. However, the inter-individual variability of sunitinib outcomes is large. Some clinical factors, such as blood pressure, can partly predict sunitinib efficacy, but they are not enough. More insight into the genetic factors underlying sunitinib outcome could also be helpful to improve optimization of treatment. In this thesis, the relevance of single nucleotide polymorphisms (SNPs) to sunitinib treatment in (cc)-mRCC patients was investigated with regard to efficacy and toxicity.We identified SNPs in IL8,IL13, VEGFR, CYP3A5 and CTLA-4 were associated with efficacy, toxicity and clearance.Further validation in independent cohorts is need before the implementation of these genetic biomarkers into clinical practice.
