Overall composition of the EST collection. The annotation of transcripts is based on SwissProt (score >150) and led to identification of mitochondrial genes. The conceptual translation of ESTs allowed detection of those that include coding sequences. The large portion of non-coding polyadenylate nuclear transcripts and RPs among nuclear transcripts is the most prominent aspect of this distribution as well as the unexpected presence of mitochondrial rRNAs (12 and 16S) related to their polyadenine stretches.
