However, wild resources of grass shrimp have declined dramatically due to overfishing and environmental destruction. Previous studies of P. sinensis are basic and sparse due to the lack of genomic data. In this study, the first transcriptome dataset of P. sinensis was obtained by performing de novo RNA sequencing. A total of 100 644 unigenes and 17 019 simple sequence repeats were identified. Potential genes and their functions were annotated by analysis of public databases. Genes encoding digestive enzymes in P. sinensis, including those specific for proteinase, carbohydrase, lipidase, as well as other related important genes, are described. The first transcriptomic investigation of P. sinensis may provide comprehensive sequence resources for grass shrimp study. Additionally, the data generated here will contribute to the identification of biomarkers for grass shrimp, and may help in understanding the links between digestive enzymes and food habit.展开更多
