| Extraction protocol |
For RNA-seq, BmN cells (1e6) with indicated treatments were harvested and total RNA of the cells was extracted using Trizol. For ChIP-seq, cells were collected and cross-linked with 1% formaldehyde for 10 min at 25˚C. The reaction was then quenched by addition of glycine to a final concentration of 125 mM. Afterwards, cells were lysed and chromatin was obtained on ice. Chromatin was sheared to a mean fragment size of 200-500 base pairs. The samples were immunoprecipitated by anti-HA antibody (Abcam, 9110).
For RNA-seq, a total amount of 1.5 μg RNA per sample was used as input material for the RNA sample preparations. Sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB) following the instructions. For ChIP-seq, sequencing libraries were generated using VAHTS Universal DNA Library Prep Kit for Illumina V3 (Vazyme, ND607) following the instructions.

| Data processing |
Raw data was cleaned by Trim Galore (Version 0.6.6) with the parameters "-q 25 --phred33 --length 36 -e 0.1 --stringency 5". For RNA-seq, cleaned data was maped to silkworm genome using HISAT2 (Version 2.2.1). The resulted SAM file was transformed to BAM file and sorted by SAMtools (Version 1.12). Mapped reads at the exons of each gene were counted via featureCounts, which is a part of the Subread (Version 2.0.1). For ChIP-seq, cleaned data was maped using Bowtie 2 (Version 2.4.4). Afterwards, the resulted SAM files were converted into BAM format using SAMtools (Version 1.12), and MACS2 (Version 2.2.7.1) was adopted for peaks calling with the parameters "-p 0.1 -f BAMPE -g 4.6e8".
