During starvation induced encystment, cells of the myxo-myceteDidymiumiridisaccumulate is the result of alternative processing of pre-rRNA. The 5¢ end corresponds to an internal processing site cleaved by the group I-like ribozyme DiGIR1, located within the twin-ribozyme intron . The RNAretains the majority including thehoming endonuclease geneanda small spliceosomal intron, the internal transcribed spacers ITS1 and ITS2, and the large subunit rRNAlacking its two group I introns. .
