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 …

RNA editing alters the identity of nucleotides in RNA molecules such that the information for
a protein in the mRNA differs from the prediction of the genomic DNA. In chloroplasts and …

The pentatricopeptide repeat (PPR) proteins form one of the largest protein families in land
plants. They are characterised by tandem 30–40 amino acid motifs that form an extended …

Members of the pentatricopeptide repeat (PPR) protein family are sequence-specific RNA-
binding proteins that play crucial roles in organelle RNA metabolism. Each PPR protein …

Aluminum (Al) stress triggers the accumulation of hydrogen peroxide (H2O2) in roots.
However, whether H2O2 plays a regulatory role in aluminum resistance remains unclear. In …

The recurrent repeats having conserved stretches of amino acids exists across all domains
of life. Subsequent repetition of single sequence motif and the number and length of the …

Mitochondria are essential for the eukaryotic cell and are derived from the endosymbiosis of
an α-proteobacterial ancestor. Compared to other eukaryotes, RNA metabolism in plant …

Pentatricopeptide repeat (PPR) proteins with an E domain have been identified as specific
factors for C to U RNA editing in plant organelles. These PPR proteins bind to a unique …

Background Nitrogen (N) is a key macronutrient essential for plant growth, and its availability
has a strong influence on crop development. The application of synthetic N fertilizers on …

Iron is an essential element for all organisms, and plants have developed sophisticated
systems to acquire iron and maintain iron homeostasis. We found that an Arabidopsis …
