  1. aThe expression patterns of each gene in salivary glands, guts, carcass, testes, and ovaries were determined by transcriptomic sequencing. “Y” indicated genes with fold changes>10 in all comparison between salivary glands and other tissues. Details in Transcripts per million (TPM) expression values of each gene was available in Supplementary Data 1. “SP” indicated the presence of signal peptide. “+” indicated the presence of protein in the sample, while “–” indicated the absence.
