Improved chromosome-level genome assembly and annotation of Chinese shrimp (Fenneropenaeus chinensis)

A high-quality reference genome is necessary to determine the molecular
mechanisms underlying important biological phenomena; therefore, in the present
study, a chromosome-level
genome assembly of the Chinese shrimp Fenneropenaeus chinensis was performed. Muscle
of a male shrimp was sequenced using PacBio platform, and assembled by Hi-C
technology. The assembled F. chinensis genome was 1.47 Gb with contig N50
of 472.84 Kb, including 57.73% repetitive sequences, and was anchored to 43
pseudochromosomes, with scaffold
N50 of 36.87 Mb. In total, 25,026
protein-coding genes were predicted.
