Synopsis of ncRNAs in Prochlorococcus MED4. Newly identified ncRNAs are based on microarray expression data or on sequence similarity (Yfr12 and Yfr18) according to the scheme shown in Figure 1.

Microarray probe IDs are given together with the respective ncRNA name, location and length. Computational support values (mean MFE z score and SVM RNA class probability) have been calculated according to Washietl et al. [65].alength determined from Northern results and verified by 5��RACE.bvalues derived from RNAz.cnot detected by Northern blot.dlength and location determined from 5��RACE results.eprecursor of Yfr10 and Yfr2.fvalues derived from consensus structure of Yfr11, Yfr16 and a single homologue in MIT9515.gvalues without MIT9301, MIT9312 and MIT9215.hvalues derived from 264 nt long RNA as determined by 5��RACE; without AS9601, MIT9301 and MIT9215.ivalues without MIT9301 and MIT9215.jvalues derived using the same MIT9301 and MIT9312 homologues.
