Re additional run on EvidenceModeler which resulted inside the prediction of 23,748 genes.3.1. Genome assembly, completeness and characterizationUsing MaSuRCA primarily based hybrid assembly, a total of 4,189 scaffolds have been obtained which was further lowered to 3484 right after scaffolding with MC3R web SSPACE program (Table 2). The Non-ATGC characters or gaps within the assembly had been decreased by lots of folds with application of GapClosure tool, followed by LR GapClosure. The 10 rounds of iteration with Pilon software program further decreased the gaps in assembly by 1.05 folds. The final assembly resulted in a high-quality draft genome of C. magur distributed in three,484 scaffolds covering 94 of genome,Magur genome unveils genetic basis of adaptationTable 2.

More info is provided in Supplementary note two.1-2. The draft genome of C. magur exhibited 95.six genome completeness (two,472 genes) such as two,377 (91.9 ) full or single copy genes, 94 (three.6 ) full and duplicated genes, 39 (1.five ) fragmented genes and 76 (3.0 ) missing genes when compared together with the BUSCO listed genes (two,586 genes). The BUSCO estimate of 95.6 completeness in the core genes within the genome was BCRP Formulation virtually similar to I. punctatus, but higher than the other catfish genomes. The final assembly obtained in this study resulted in higher continuity and completeness from the genome as the N50 value was greater than the C. batrachus and Pelteobagrus fulvidraco assemblies, but reduce than the I. punctatus and P. hypophthalmus (Supplementary Table S1). The analyses of this genome offer a extensive understanding in the evolution of C. magur with respect to other fish species plus the genes/gene households which had been evolved in C. magur for environmental/terrestrial adaptation. The GC content in C. magur genome (39.83 ) is slightly larger than the C. batrachus (39.two ), I.
