Comparative genomics of rohu (A) Venn diagram showing orthologous gene clusters among four diploid cyprinids, Labeo rohita, Anabarilius grahami, Ctenopharyngodon idellus, and Danio rerio. (B) Synteny conservation between rohu and zebrafish using Symap. The genome view is depicted by Circos plot where 25 zebrafish chromosomes (1 to 25) are shown in upper side and 188 largest scaffolds of rohu in the lower side of the ring. The connecting ribbons indicate the location of conserved synteny blocks between the two species. (C) Phylogenetic relationships of Labeo rohita with 13 other otophysans, inferred from 335 single-copy orthologous genes (protein sequences). Otophysan orders, families and subfamilies are identified by vertical bars against species names. ML bootstrap values are shown at the nodes.
