The chloroplast can act as an environmental sensor, communicating with the cell during
biogenesis and operation to change the expression of thousands of proteins. This process …

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 …

Chloroplasts are the organelles that define plants, and they are responsible for
photosynthesis as well as numerous other functions. They are the ancestral members of a …

Plastids communicate their developmental and physiological status to the nucleus via
retrograde signaling, allowing nuclear gene expression to be adjusted appropriately …

The term retrograde signaling refers to the fact that chloroplasts and mitochondria utilize
specific signaling molecules to convey information on their developmental and physiological …

Like all aerobic organisms, plants and algae co-opt reactive oxygen species (ROS) as
signalling molecules to drive cellular responses to changes in their environment. In this …

Chloroplasts produce singlet oxygen (1O2), which causes changes in nuclear gene
expression through plastid-to-nucleus retrograde signaling to increase plant fitness …

Communication between cellular compartments is vital for development and environmental
adaptation. Signals emanating from organelles, so-called retrograde signals, coordinate …

A fundamental mystery of plant cell biology is the occurrence of “stromules,” stroma-filled
tubular extensions from plastids (such as chloroplasts) that are universally observed in …

Abstract Significance: Reduction-oxidation (Redox) status operates as a major integrator of
subcellular and extracellular metabolism and is simultaneously itself regulated by metabolic …
