The role of alpha-tocopherol in the protection of tomato plants against abiotic stress

Spicher, Livia ; Kessler, Felix (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

The ability of energy conversion by the photosynthetic machinery under stress and its capacity to adjust to an ever-changing environment is crucial for plant survival. The photosynthetic light reactions occur at the photosystems in the thylakoids of chloroplasts. The photosystems are composed of proteins in a specific lipid environment. It includes not only membrane lipids but also lipophilic...

Moving towards the understanding of dynamic human face processing

Richoz, Anne-Raphaëlle ; Caldara, Roberto (Dir.)

Thèse de doctorat : Université de Fribourg, 2018.

The human visual system is steadily stimulated by dynamic cues. Faces provide crucial information about identity, gender, ethnicity, speech, attention, eye-gaze direction, or emotions, all important for adapted social interactions. From an evolutionary perspective, humans have been more extensively exposed to dynamic faces, as static face images have only appeared recently with the advent of...

Engineering metal oxides for UV-stable perovskite solar cells

Roose, Bart ; Steiner, Ullrich (Dir.)

Thèse de doctorat : Université de Fribourg, 2017 ; no. 2015.

This thesis is a study of the role of the metal oxide electron transporting material in perovskite solar cells. The central research question is how the metal oxide influences the stability of perovskite solar cells and how the metal oxide can be modified to improve the stability. The thesis begins by providing four background chapters. Chapter 1 explains the need for solar energy and what...

Genetic control of photoreceptor terminal differentiation in Drosophila melanogaster

Bernardo-Garcia, F. Javier ; Sprecher, Simon (Dir.)

Thèse de doctorat : Université de Fribourg, 2018 ; no. 2066.

Why do photoreceptors differentiate in the eye? Though simple, biologically this is an important question, and it may prove complex to answer. To present a bigger picture: animals have evolved a diversity of highly specialised sensory organs, which they use to obtain information from their environment and thus survive. These organs contain different types of receptor neurons. For example, there...

The functions of RMR proteins in the "Physcomitrella patens" secretory pathway

Fahr, Noémie ; Neuhaus, Jean-Marc (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Plant vacuoles play a wide range of functions within the cell, from the maintenance of turgor pressure and rigidity, to the storage or degradation of various molecules. Two types of vacuoles with distinct pH can coexist in the same single cell. Acidic vacuoles can be considered as homologues to animal lysosomes while neutral vacuoles are involved in proteins and secondary metabolites storage....
