The near telomere-to-telomere genome of the Murray cod (Maccullochella peelii)
摘要
Maccullochella peelii, commonly known as Murray cod, is an endemic economic fish from the Australian freshwater systems. In order to provide high-quality reference genome for its genomic studies, we assemble and annotate the first near telomere-to-telomere genome of this species which spans 762.84 Mb with a contig N50 of 31.21 Mb, 99.02% sequences were positioned to 24 chromosomes by Hi-C assembly. After gap filling using ONT ultra-long reads, yielding 22 gapless chromosomes. Based on homologous predictions and RNA-sequencing, 27,380 protein-coding genes were identified, and the functions were predicted for 24,998 (91.3%) of them. Moreover, assembled genome was evaluated as 99.3% single-copy BUSCOs completeness. This work could provide a foundation and high-quality genomic resources for the future research on molecular breeding and population genetics of this species.
