Overview of the divisions of DEGs of testes and ovaries into 8 categories (Cat) based on their tissue-preferential/specific and pairing-dependent transcript occurrence.

Cat 1.1: Testis-preferential/specific and pairing-affected genes. Cat 1.2: Testis-preferential/specific and pairing-unaffected genes. Cat 2.1: Ovary-preferential/specific and pairing-affected genes. Cat 2.2: Ovary-preferential and pairing-unaffected genes. Cat 3.1: Pairing-affected genes in both gonads. Cat 3.2: Pairing-unaffected genes in both gonads. Cat 4.1: Transcripts of genes affected by pairing in testes but not in ovaries. Cat 4.2: Transcripts of genes affected by pairing in ovaries but not in testes. (a) Graphical illustration of the categories. The left and right parts indicate DEGs in testes (bT/sT) and ovaries (bO/sO), respectively. Grey color indicates genes that were not found to be significantly differentially transcribed. Blue and yellow areas represent genes whose transcript numbers were significantly lower or higher after pairing, respectively. (b) Transcript profiles of one representative gene of each category on a relative basis of transcript amounts. To provide more information about the transcript profiles of categorized genes, we added their relative expression also for the adult samples. The selected genes represent a cell-division cycle phosphatase cdc25 (Smp_152200; Cat 1.1), elav (embryonic lethal, abnormal visual system) (Smp_194950; Cat 1.2), cpeb1 (cytoplasmic polyadenylation element binding) (Smp_070360; Cat 2.1), a sox transcription factor (Smp_076600; Cat 2.2), a potassium channel of the twik (tandem of P domains in a weakly inward rectifying K⁺ channel) family (Smp_147550; Cat 3.1), lin-9 (Smp_133660; Cat 3.2), a von-Willebrand factor A (vWA) domain-containing protein gene (Smp_127480; Cat 4.1) and melk (maternal embryonic leucine zipper kinase) (Smp_166150; Cat 4.2).
