Abstract Background Transitions from sexual to asexual reproduction are common in eukaryotes, but the underlying mechanisms remain poorly known. The pea aphid—Acyrthosiphon pisum—exhibits reproductive polymorphism, with cyclical parthenogenetic a

Males and females share essentially the same genome but differ in their optimal values for many phenotypic traits, which can result in intra-locus conflict between the sexes. Aphids display XX/X0 sex chromosomes and combine unusual X chromosome inher

International audience; CRISPR-Cas9 technology is a very efficient functional analysis tool and has been developed in several insects to edit their genome through injection of eggs with guideRNAs targeting coding sequences of genes of interest. Howev

Small non-coding RNAs are key post-transcriptional and transcriptional regulators of plant gene expression in angiosperm sporophytes. In recent years, gametophytic small RNAs have also been investigated, predominantly in Arabidopsis male gametophytes

International audience; Seasonal photoperiodism in aphids is responsible for the spectacular switch from asexual to sexual reproduction. However, little is known on the molecular and physiological mechanisms involved in reproductive mode shift throug
