Clock genes and photoperiodism in the aphid Acyrthosiphon pisum

2017

Aphids have a strong seasonal response, namely the development of a sexual morphs triggered by the shortening of photoperiod in autumn that produce an overwintering egg in which an embryonic diapause takes place. From this egg, an asexual parthenogenetic female emerges giving way to the asexual phase of the aphid life cycle in which several asexual generations occur. Based on the response to short photoperiods, two strains of aphids can be found: the holocyclic develop the seasonal response under short photoperiods, while the anholocyclic do not. The sequencing of the genome of the pea aphid Acyrthosiphon pisum places this species as an excellent model to investigate the the involvement of …
