The genomic region containing Nv1 neurotoxin genes. (A) Graphic map of the region on scaffold 116 in the Nematostellavectensis genome draft, which contains 8 Nv1 genes (positions 580000–620000). The genes colored in bright blue and indicated by vertical lines are named according to the Joint Genome Institute Web site nomenclature (http://genome.jgi-psf.org/Nemve1/Nemve1.home.html), and their transcriptional orientation is indicated by arrows. Sequencing gaps are colored in gray. (B) Enhanced graphic output of a BlastN query on part of the Nv1 region on scaffold 116 (positions 605800–623000) using the 116.39.1 gene and its adjacent sequences (1,000-bp upstream and 1,000-bp downstream). Gene ID is indicated above the location on the scaffold. The conserved gene structure of Nv1 and its relative position in the query appear above the Blast diagram. The 2 exons are in orange and the intron is designated by a black line.
