Kin recognition: Neurogenomic response to mate choice and sib mating avoidance in a parasitic wasp.

摘要: Sib mating increases homozygosity, which therefore the risk of inbreeding depression. Selective pressures have favoured evolution kin recognition and avoidance sib in numerous species, including parasitoid wasp Venturia canescens. We studied female neurogenomic response associated with after females were exposed to courtship displays by i) unrelated males or ii) related iii) no (controls). First, comparing transcriptional responses those controls, we saw a rapid extensive shift consistent social environment. Second, males, characterized distinct repeatable transcriptomic patterns that correlated relatedness courting male. Network analysis revealed 3 modules specific 'sib-responsive' genes from other 'courtship-responsive' modules. Therefore, states characteristic brain transcriptomes different behavioural affect behaviour.
