The splicing factor SPR2 interacts with the RNA-binding protein PPR8 to facilitate mitochondrial intron splicing and is essential for maize seed development

Intron splicing plays a crucial role in organellar gene expression in plants, yet its mechanism remains poorly understood. We previously reported a small PPR protein, SPR2, which is a general splicing factor in the splicing of over half of the mitochondrial introns via interactio...
