DNA-binding proteins acting as cofactors of phage-type RNA polymerases
in yeast and animal mitochondria have long served as models
for investigating mitochondrial transcription in plants. However, a biochemical
strategy for recoveringmtDNA-binding proteins that had been
successful for the purification of Abf2/TFAM from yeast/human cells
failed to identify homologous proteins in pea mitochondria
