Figure 1From: Transcriptome profiling of developmental and xenobiotic responses in a keystone soil animal, the oligochaete annelid Lumbricus rubellusProportional representation of ESTs within clusters for sequences determined from each L. rubellus cDNA library. The figure illustrates the proportion of the ESTs generated from each library which are associated within clusters containing a total of 1 (singletons, Black bars), 2–9 (grey bars) and 10 or more ESTs (Clear bars).Back to article page
