Genetic Map of Fugu (the Tiger Pufferfish)

May, 2011.

The tiger pufferfish, Takifugu rubripes (fugu) was proposed as a genomic model because of its compact genome. The genome of fugu was sequenced to the draft level in 2002 as the second vertebrate genome to be fully sequenced. However, the assembly of the draft genome sequence is highly fragmented due to the lack of a chromosomal coordinate. To extend the contiguity of the assembly to the chromosomal level, we have generated the second generation genetic map of fugu and anchored the scaffolds of the assembly to the 22 chromosomes of fugu. The map consists of 1,220 microsatellite markers that provide anchor points to scaffolds covering 86% of the genome assembly.The consolidated genome map of fugu is a valuable resource for comparative genomics and for elucidating the genetic basis of the phenotypic diversity of ∼25 species of fugu and its related species that diverged within the last 5 million years.
