show Abstracthide AbstractB. mori is a model insect of Lepidoptera. Study on the mechanism of B. mori embryonic development will help to find embryo-specific targets for enhancing beneficial insect populations and for pest control. In the present study, the transcriptome of B. mori embryos at different developmental stages was sequenced, the differentially expressed genes (DEGs) between development stages were analyzed. The results will provide data for further research on the physiological and biochemical mechanisms of B. mori embryonic development.
