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 …

The large mitochondrial genomes of angiosperms are unusually dynamic because of
recombination activities involving repeated sequences. These activities generate …

Plant organellar RNA metabolism is run by a multitude of nucleus-encoded RNA-binding
proteins (RBPs) that control RNA stability, processing, and degradation. In chloroplasts and …

Chloroplast translation is essential for cellular viability and plant development. Its positioning
at the intersection of organellar RNA and protein metabolism makes it a unique point for the …

Plant terrestrialization brought forth the land plants (embryophytes). Embryophytes account
for most of the biomass on land and evolved from streptophyte algae in a singular event …

Pentatricopeptide repeat (PPR) proteins are RNA-binding proteins that are particularly
prevalent in terrestrial plants. Although the PPR protein family was only recognized eight …

Abstract Thioredoxins (Trx) and glutaredoxins (Grx) constitute families of thiol
oxidoreductases. Our knowledge of Trx and Grx in plants has dramatically increased during …

Plastid-to-nucleus retrograde signaling coordinates nuclear gene expression with
chloroplast function and is essential for the photoautotrophic life-style of plants. Three …

Plastid genes are transcribed by two types of RNA polymerase in angiosperms: the bacterial
type plastid-encoded RNA polymerase (PEP) and one (RPOTp in monocots) or two (RPOTp …
