recommendations! Published in 2024 at "Planta"

DOI: 10.1007/s00425-024-04354-w

Abstract: The Arabidopsis Pentatricopeptide repeat 40 (PPR40) insertion mutants have increased tolerance to water deficit compared to wild-type plants. Tolerance is likely the consequence of ABA hypersensitivity of the mutants. Plant growth and development depend on… read more here.

DOI: 10.1038/s41598-018-34377-9

Abstract: Pentatricopeptide repeat (PPR) proteins, a helical repeat family of organellar RNA binding proteins, play essential roles in post-transcriptional RNA processing. In Trypanosoma brucei, an expanded family of PPR proteins localize to the parasite’s single mitochondrion,… read more here.

DOI: 10.1093/bib/bbac369

Abstract: In order to identify plant pentatricopeptide repeat (PPR) proteins, a framework of variable selection has been proposed. In fact, it is an effective feature selection strategy that focuses on the performance of classification. Random forest… read more here.

DOI: 10.1093/jxb/ery275

Abstract: Three nuclear encoded multi-functional pentatricopeptide repeat proteins localizing in the mitochondrion are involved in splicing of a cohort of mitochondrial group II introns and thereby required for complex I biogenesis. read more here.

DOI: 10.1093/nar/gkaf1169

Abstract: Pentatricopeptide repeat (PPR) proteins are eukaryotic RNA binding proteins with multiple roles in mitochondrial and chloroplast transcript processing. PPR proteins are naturally modular and hold great potential for development into tools for RNA processing or… read more here.

DOI: 10.1093/plphys/kiac086

Abstract: Mitochondrial function relies on the assembly of electron transport chain complexes, which requires coordination between proteins encoded by the mitochondrion and those of the nucleus. Here, we cloned a maize (Zea mays) cytochrome c maturation… read more here.

DOI: 10.1093/plphys/kiac309

Abstract: Gene expression in plant mitochondria is predominantly governed at the post-transcriptional level and relies mostly on nuclear-encoded proteins. However, the protein factors involved and the underlying molecular mechanisms are still not well understood. Here, we… read more here.

recommendations! Published in 2020 at "Plant Physiology"

DOI: 10.1104/pp.20.01406

Abstract: Chloroplasts are semiautonomous organelles that retain their own genomes derived from their cyanobacterial ancestors, but with reduced size and gene number. However, chloroplast genes cannot function autonomously. Instead, nucleus-encoded factors are required for all steps… read more here.

DOI: 10.1111/jipb.13147

Abstract: Pentatricopeptide repeat (PPR) proteins play important roles in the posttranscriptional modification of organellar RNAs in plants. However, the function of most PPR proteins remains unknown. Here, we characterized the rice (Oryza sativa L.) chlorophyll deficient… read more here.
