The study of plant mitochondria started in earnest around 1950 with the first isolations of
mitochondria from animal and plant tissues. The first 35 years were spent establishing the …

The central dogma in biology defines the flow of genetic information from DNA to RNA to
protein. Accordingly, RNA molecules generally accurately follow the sequences of the genes …

Pentatricopeptide repeat (PPR) proteins constitute one of the largest protein families in land
plants, with more than 400 members in most species. Over the past decade, much has been …

Mitochondria are central to cellular metabolism and energy conversion. In plants they also
enable photosynthesis through additional components and functional flexibility. A majority of …

The respiratory electron transport chain (ETC) couples electron transfer from organic
substrates onto molecular oxygen with proton translocation across the inner mitochondrial …

The last steps of cellular respiration—an essential metabolic process in plants—are carried
out by mitochondrial oxidative phosphorylation. This process involves a chain of multi …

We have analyzed the distribution of mitochondrial contact site and cristae organizing
system (MICOS) complex proteins and mitochondrial intermembrane space bridging …

Iron is an essential element for all photosynthetic organisms. The biological use of this
transition metal is as an enzyme cofactor, predominantly in electron transfer and catalysis …

Mitochondrial complex III (CIII2) and complex IV (CIV), which can associate into a higher-
order supercomplex (SC III2+ IV), play key roles in respiration. However, structures of these …

Abstract Mitochondrial Oxidative Phosphorylation (OXPHOS) provides ATP for driving
cellular functions. In plants, OXPHOS takes place in the context of photosynthesis. Indeed …
