We developed high throughput Solexa sequencing and bioinformatic analyses of the genome of the pea aphid Acyrthosiphon pisum in order to identify the first miRNAs from a hemipteran insect. By combining these methods we identified 155 miRNAs including 56 conserved and 99 new miRNAs. Moreover, we inve...
ORGANISM(S): Acyrthosiphon pisum 
Aphid adaptation to harsh winter conditions is illustrated by an alternation of their reproductive mode. Aphids detect photoperiod shortening by sensing the length of the night and switch from viviparous parthenogenesis in spring and summer, to oviparous sexual reproduction in autumn. The photoperio...

Root-knot nematodes (RKNs) induce inside the vascular cylinder the giant cells (GCs) imbibed into a gall. Gene-repression in early developing GCs could be facilitated by small RNAs (sRNA) as miRNAs. 24nt-sRNAs, rasiRNAs and 21-22nt-sRNAs can also mediate epigenetic mechanisms. Three sRNA libraries f...
