21. Characterization of Epoxide Hydrolases from Yeast and Potato
Sammanfattning : Epoxides are three-membered cyclic ethers formed in the metabolism of foreign substances and as endogenous metabolites. Epoxide hydrolases (EHs) are enzymes that catalyze the hydrolysis of epoxides to yield the corresponding diols. LÄS MER
22. Barrier and Mechanical Properties of Starch Films Based on Regular Potato Starches and High Amylose Potato Starches
Sammanfattning : The object of this work was to investigate the film properties of modified regular potato starch and modified high amylose potato starch with different small molecules tested as possible plasticizers. The studies focused on barrier properties such as water vapour permeability (WVP, WVPe), the glass transition temperature (Tg) and mechanical (tensile) properties. LÄS MER
23. Phosphorus application strategies in potato : constraints and potential improvements
Sammanfattning : Phosphorus (P) is an essential element that plays an important role in carbohydrate metabolism and energy transfer systems in all plants. Sufficient P supply is therefore essential for providing adequate food, fibre and fuel for society. In potato, P deficiency reduces yield and tuber number due to reduced radiation interception by the canopy. LÄS MER
24. Distribution and diversity of Potato mop-top virus in Sweden
Sammanfattning : During the last decades, spraing disease caused by Potato mop-top virus (PMTV) has become a severe problem in the potato production throughout the Nordic countries. In this thesis, it was shown that PMTV is widely distributed throughout Sweden, Norway and Denmark, and has now become prevalent in the potato-production areas within these countries. LÄS MER
25. Small RNAs in Phytophthora infestans and cross-talk with potato
Sammanfattning : Small RNAs (sRNAs) are small non-coding RNAs usually ranging in size 20-30 nt. They are playing important roles in plant-pathogen interactions. This thesis aimed at studying the sRNA populations in potato and Phytophthora infestans and their role in the potato-P. infestans interaction. LÄS MER
