Genomic innovations underlying the evolution of termite social behaviour

  • The phylogeny of the Blattodea boasts a wide degree of sociality spanning from solitary cockroaches to advanced ecosystem-dominating higher termite societies. The emergence of sociality in the termites was associated with the acquisition of a diverse range of social structures and differential expression of specific gene network. Previous work has found evidence for a caste-specific social defence system in termites leading to an immune system that may favour group over individual defence. While preliminary work suggests a correlation between social transitions and a reduction of immune gene family diversity, the lack of available high-quality termite genomes hampers complete knowledge of the true diversity of immune gene evolution across termite phylogeny. Here, we report on the sequencing and assembly of 50 high-quality long-read-based genomes and 180 caste- and sex-specific brain transcriptomes across major termite and cockroach sister-branch lineage.

We investigate the diversity and evolutionary history of immune genes across genomes, and the potential gene networks that have evolved with the emergence of termite sociality and some aspect of immune related behaviours.zeige mehrzeige weniger
