Fig. 5From: Unexpected diversity of CRISPR unveils some evolutionary patterns of repeated sequences in Mycobacterium tuberculosisCRISPR-Cas locus likely structure of each lineage MRCA. See Fig. 2 for legend. Additional empty boxes highlight deletions typical of each lineage. The proposed structure was designed by a parsimonious approach based on the CRISPR structure of the 198 clinical isolatess fully characterized in Supplementary file 3 (See also notes common with Fig. 2)Back to article page
