A exciting research paper "Control of alternative RNA splicing and gene expression by eukaryotic riboswitches" published in Nature details the mechanism of how riboswitches work in Neurospora crassa. While riboswitches have been found and studied in bacteria there has not been extensive work showing how they work in fungi. In bacteria the riboswitch acts as the direct interacting sensor that switches gene
