Abstract excerpt
Pentatricopeptide repeat proteins (PPRPs) constitute one of the largest superfamilies in plants, with more than 440 identified in the Arabidopsis thaliana (L.) Heynh genome. While some PPRPs are known to take part in organelle gene expression, little is known about the broader biological contexts of PPRP gene function. Here, using developmental- and reverse-genetic approaches, we demonstrate that a number of...
