RNA-binding proteins (RBPs) are important for RNA editing in living organisims. We recently found that plants lacking an RBP (RBP4) have a smaller size, yellow green leaves, reduced photosynthetic efficiency, and decreased abundances of photosynthetic proteins. Surprisingly, the corresponding messenger RNAs are either unchanged or increased. Next-generation sequencing of RNA populations showed that these plants have lower editing efficiencies at the PsbF and accD editing sites. PsbF is a core protein in photosystem II and accD is a key protein in fatty acid biosynthesis. Our hypothesis is that RBP4 is involved in editing of PsbF and accD messenger RNAs.
