Clusters of orthologous groups (COG) functional classification of nucleotide sequences in the S. gregaria midgut transcriptome. COG assignments were based on the COG alphabet, retrieved from the Swiss-Prot database and used to cluster transcripts according to predicted orthology. A total of 7,142 transcripts (36.9%) of the midgut transcriptome could be attributed to at least one COG category. The number of transcripts is plotted on the x-axis. The different COG categories are shown on the y-axis.
