When switching from green to yellow, a leaf undergoes both morphological and metabolic changes. This process is known as senescence and improved understanding of its mechanisms is important both from a fundamental scientific perspective but also for biotechnological applications. The present thesis reports on several important aspects regarding the cellular and metabolic mechanisms occurring during leaf senescence with an emphasis on the mitochondrial contribution to this process. As a first step, we developed methods to isolate either highly functional crude mitochondria or highly purified mitochondria from leaves of Arabidopsis thaliana. These methods were further used to study mitochondrial contributions to cellular redox homeostasis and...
