Lineage-specific loss of antisense transcription at the sel-2 locus. a Gene tree of sel-2. b Gene tree of mab-21. c Genomic configuration of host gene and ASTs at the sel-2 and mab-21 locus in 20 nematode genomes. The first exons of sel-2 in M. incognita and H. contortus could only be identified on different contigs indicating towards some minor assembly problem in this region. However, in both Pristionchus species, alignments for sel-2 are rather complete and mab-21 has clearly translocated out of the longest sel-2 intron
