TY - CONF A1 - McMahon, Dino Peter T1 - Termite Immunity (a molecular perspective) N2 - In this presentation, an overview of the termite immune system is given. The presentation covers the mechanistic underpinnings of the canonical immune pathways in insects; where there are areas of conservation or divergence in termites, as well as briefly going over some key gaps in knowledge. External immune capabilities are discussed as well as the implications and consequences of sociality for the evolution of collective immune defense systems in termites.

Reconstructing the transitions that led to the evolution of this group of ecologically dominant insect societies is challenging. We sought to address this by sequencing near-chromosome-quality genomes from the major solitary, subsocial and social lineages of termites and their nearest blattodean relatives. We present findings from a comparative analysis of the sequenced genomes, where we explore the molecular underpinnings of termite sociality, and seek to understand the evolutionary origins of termite castes. At a broader scale, we test the extent to which a two-step process involving an initial expansion of genomic elements in cockroaches followed by extensive genome rearrangements in termites, may have acted as an important mechanism of evolutionary change. We then ask whether specific genomic processes may have facilitated evolutionary novelty, for example, through the analysis of transposon-host gene associations across the social gradient. We also report on findings that combine genomes with brain transcriptomics to explore the mechanistic basis of termite phenotypic plasticity, thereby enabling a first large-scale comparative genomic analysis of the evolutionary origins of termite sociality.
