3.5 Transcriptome data analysis
We found there were 8,108 tissue-specific expression genes in theC. sonnerati genome, based on the detailed analysis of transcriptome data from 11 tissues of C. sonnerati (Figure 6). Interestingly, the tissue-specific expression genes were highly enriched in the brain of C. sonnerati , which was different from the results of the expanded gene families enrichment analysis in theC. sonnerati genome. These tissue-specific expression genes were annotated to the KEGG (Kyoto Encyclopaedia of Genes and Genomes) pathway database for functional analysis. The results showed that these genes mainly consisted of complement and coagulation cascades, DNA replication, synaptic vesicle cycle, long-term potentiation, and other glycan degradation.
