The novel chloroplast outer membrane kinase KOC1 is a required component of the plastid protein import machinery

Zufferey-Arias, Mónica Alexandra ; Kessler, Felix (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

The chloroplast constitutes the site of photosynthesis and is an essential organelle in plant cells. An endosymbiotic event was at the origin of the chloroplast, an ancestral eukaryotic cell engulfing a photosynthetic cyanobacterium. During evolution, the majority of ancestral chloroplast genes were lost or transferred to the nucleus. The protein products of the successfully transferred genes are...

Evaluation of a yeast system for studying the function of plant vacuolar sorting receptors (VSRs)

Hodel Hernandez, Doramys ; Neuhaus, Jean-Marc (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2005 ; 1800.

The yeast S.cerevisiae is not an efficient tool for in vivo studies of plant vacuolar sorting receptors Plant and yeast vacuoles, the equivalents of mammalian lysosomes, are acidic compartments involved in hydrolytic functions. They are also essential for metabolite storage and for maintaining cytosolic ion and pH homeostasis (Klionsky and Emr, 1990; Wink, 1993). The vacuoles mainly receive...
