Chromosome-level genome assembly and annotation of the critically endangered Siberian crane
The Siberian crane (Leucogeranus leucogeranus) is an IUCN Critically Endangered waterbird, with an estimated number of over 6,900 individuals in East Asia and extinction of wild populations in Western/Central Asia. Here, we generate a high-quality chromosome-level genome of the Siberian crane by integrating Nanopore long-reads data, BGI short-reads data and Hi-C data. A total of 1.31 Gb genome was obtained with a scaffold N50 of 87.88 Mb, including 33 chromosomes and other unplaced scaffolds. BUSCO assessment exhibited 97.6% complete genes in the genome assembly. 10.9% of repetitive sequences and 21,678 protein-coding genes were identified in the genome. All genes were successfully assigned functional annotations. This high-quality genome assembly and annotation provide a valuable genomic resource for the comparative genome research to understand the ecology, evolutionary adaptation and development of Gruidae birds.
