A chromosome-level genome assembly of the Asian giant softshell turtle Pelochelys cantorii
Scientific data(2023)
摘要
The Asian giant softshell turtle Pelochelys cantorii is one of the largest aquatic turtles in China and has been designated a First Grade Protected Animal in China. To advance conservation research, a combination of Illumina short-read, PacBio long-read, and Hi-C scaffolding technologies was used to develop a high-quality chromosome-level genome assembly for P. cantorii . A total of 262.77 Gb of clean data were produced (121.6 × depth) and then the genome was assembled into 2.16 Gb with a contig N50 of 41.44 Mb and scaffold N50 length of 120.17 Mb, respectively. Moreover, about 99.98% assembly genome sequences were clustered and ordered onto 33 pseudochromosomes. Genome annotation revealed that 21,833 protein-coding genes were predicted, and 96.40% of them were annotated. This new chromosome-level assembly will be an enabling resource for genetic and genomic studies to support fundamental insight into P. cantorii biology.
