A chromosome-level genome assembly of the Asian arowana, Scleropages formosus

چکیده
Asian arowana (Scleropages formosus), an ancient teleost belonging to the Order Osteoglossomorpha, has been a valuable ornamental fish with some varieties. However, its biological studies and breeding germplasm have been remarkably limited by the lack of a reference genome. To solve these problems, here we report high-quality genome sequences of three common varieties of Asian arowana (the golden, red and green arowana). We firstly generated a chromosome-level genome assembly of the golden arowana, on basis of the genetic linkage map constructed with the restriction site-associated DNA sequencing (RAD-seq). In addition, we obtained draft genome assemblies of the red and green varieties. Finally, we annotated 22,016, 21,256 and 21,524 protein-coding genes in the genome assemblies of golden, red and green varieties respectively. Our data were deposited in publicly accessible repositories to promote biological research and molecular breeding of Asian arowana.

The Asian arowana (Scleropages formosus) genome provides new insights into the evolution of an early lineage of teleosts.
The Asian arowana (Scleropages formosus), one of the world's most expensive cultivated ornamental fishes, is an endangered species. It represents an ancient lineage of teleosts: the Osteoglossomorpha. Here, we provide a high-quality chromosome-level reference genome of a female golden-variety arowana using a combination of deep shotgun sequencing and high-resolution linkage mapping. In addition...

Isolation and characterization of novel microsatellite markers in commercial selected golden Malaysian arowana fish, Scleropages formosus (Osteoglossidae).
Malaysian arowana (dragonfish; Scleropages formosus) is an ancient osteoglossid fish from southeast Asia. Due to the high demand of the ornamental fish trade and because of habitat loss, the species is close to extinction. We isolated and characterized 10 polymorphic microsatellites of this species, using 5'-anchored PCR. The number of alleles at the 10 microsatellite loci ranged from 2 to 28, ...

One of the traditional enigmas in freshwater zoogeography has been the evolutionary origin of Scleropages formosus inhabiting Southeast Asia (the Asian arowana), which is a species threatened with extinction among the highly freshwater-adapted fishes from the order Osteoglossiformes. Dispersalists have hypothesized that it originated from the recent (the Miocene or later) transmarine dispersal ...

The present research describes a simple method for the identification of the gender of arowana fish (Scleropages formosus). The DNA biosensor was able to detect specific DNA sequence at extremely low level down to atto M regimes. An electrochemical DNA biosensor based on acrylic microsphere-gold nanoparticle (AcMP-AuNP) hybrid composite was fabricated. Hydrophobic poly(n-butylacrylate-N-acrylox...
