Short, non-coding plant organellar RNAs

An interesting side aspect of the PPR work was the identification of chloroplast sRNAs as binding sites of PPR proteins (Ruwe and Schmitz-Linneweber, 2012). This finding has turned into one of the larger projects currently running in the group. We found sRNAs as PPR targets in chloroplasts of many different species as well as in mitochondria. These sRNAs are potential regulators of plant organellar gene expression and are also allowing insights into how RNAs are degraded in these compartments. We will continue working on this in the upcoming years.
