The team's analysis of CRISPR repeat and spacer sequences revealed that although there is a set of CRISPRs maintained within each subject over time, ranging from 7 percent to 22 percent, there was a remarkable amount of change observed even in short periods.
Therefore the internal transcribed spacers (ITS) regions are rather interesting for studies on taxonomy and identification, because the spacer sequences have revealed intraspecific variation when analysed by RFLP, frequently both in sequence and size (Sollner-Webb and Mougey, 1991; Matioli, 2001).
