In nematodes, the 22 nucleotide (nt) spliced leader (SL) is normally encoded by a multi-copy, tandemly reiterated SL gene and is trans-spliced from SL-RNA onto the 5' end of a subset of mRNAs. We have found that the SL is also encoded at multiple (> 100) orphon genomic sites in the parasitic nematode Angiostrongylus cantonensis. At these sites the sequence forms part of a 198 bp repetitive elem...
