The circles shown in red dotted outline and green solid outline, excluding the central pale green curve-sided triangular area, indicate the numbers of known sRNAs predicted by sRNAscanner without and with the use of a CSS cut-off (CSS>14), respectively. The central pale green curve-sided triangular area, including the innermost circle outlined in purple, represents the 118 novel, intergenic, non-overlapping candidate sRNAs predicted in this study; the innermost circle outlined in purple represents the 16-member subset comprising sRNA candidates found to have likely mRNA transcripts by comparison with RNA deep sequencing datasets , . The $ superscript symbol indicates the five candidates belonging to both the Pfeiffer et al. and Sittka et al. , sets; the asterisk symbol denotes the one sRNA candidate mapping to the Padalon-Brauch et al. , Papenfort et al. and Sittka et al. , sets.
