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 understo

Production and expression of RNAs requires the action of multiple RNA-binding proteins (RBPs). New RBPs are most often created by novel combinations of dedicated RNA binding modules. However, recruiting existing genes to create new RBPs is also an im

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.
Group II introns are c
