Distribution of cDNA types from A. locustae ESTs. (A) Classification of all 1,146 A. locustae mRNA clones according to what they encode. Twenty-four percent have no identifiable similarity to known sequences, 1% are fragments of the A. locustae rRNA operon, and 2% are an expressed repeated element known in the catalase intergenic region from A. locustae. Thirteen percent encode only the antisense of protein-coding genes, and 15% of these (extended wedge) encode antisense of more than one gene. Sixty-one percent encode sense of identifiable genes, and, of these, 11% (extended wedge) encode fragments of two or more genes in sense or antisense strands. (B–I) Schematic diagrams of multigene transcript types, with the numbers of instances of each type indicated by numbers on the right. All cDNAs are oriented with the polyA to the right. Arrows are not to scale, because each type may represent several different loci.
