Tissue expression pattern of Bdkrb2 genes. a Heatmap was constructed by comparing different tissues. The x‐axis showed sampled tissues, with the prefix F_ for female and M_ for male samples, and the y‐axis shows genes. The color scale showed standardized TPM values normalized by Z-score method. Gene expression patterns could be roughly divided into gill-type, intestine-type and reproductive organ-type. b The expressions of Bdkrb2 genes in ovarian wall at the stage of post-mating and pre-fertilization. The x‐axis showed genes and the y‐axis shows TPM (Transcripts Per Million). The numeric data were presented as mean ± SD. Statistical significance was tested by one-way ANOVA followed by Tukey’s HSD (harmonic mean sample size = 3, degrees of freedom = 7, subset for alpha = 0.05) using SPSS 20.0 (SPSS, Armonk, NY, USA) and accepted when p < 0.05
