Identification of 88 regulatory small RNAs in the TIGR4 strain of the human pathogen Streptococcus pneumoniae

Distribution of the small RNAs isolated from the S. pneumoniae TIGR4 strain. The sector diagram shows the distribution of the 1047 cDNA contigs obtained (after the removal of rRNAs and tRNAs) with regard to their origin and genetic context. The chart shows the number of RNAs assigned to each of the following categories: intragenic RNAs that overlap entirely with an ORF; 5′- or 3′-overlapping RNAs that overlap with the 5′ or 3′ end of an ORF; 5′/3′-overlapping RNAs that overlap with two adjacent genes simultaneously; and intergenic sRNAs, RNAs entirely encoded in intergenic regions.
