Fig. 2
Multiple sequence alignment of putative leader sequences and the first repeats. The putative leader sequence (107Â bp) and the first repeat (47Â bp) of each CRISPR1 locus in analyzed strains were selected for multiple sequence alignment. The nucleotide sequences of the first repeats are framed by black box. The grey shadow and arrow indicate the palindromic sequence in leaders. The asterisk represents the conserved base in all of the sequences for alignment
