(Submitter supplied) The pea aphid, Acyrthosiphon pisum, exhibits several environmentally cued polyphenisms, in which discrete, alternative phenotypes are produced. At low density parthenogenetic females produce unwinged female progeny, but at high density females produce progeny that develop with wings. These alternative phenotypes represent a solution to the competing demands of dispersal and reproduction. Males also develop as either winged or unwinged, but these alternatives are determined by a genetic polymorphism. more...

(Submitter supplied) Developmental mechanisms play an important role in determining the costs, limits, and evolutionary consequences of phenotypic plasticity. One issue central to these claims is the metaphor of developmental “decoupling,” where alternate morphs result from evolutionarily independent developmental pathways. We test this assumption through a microarray study that explores differences in gene expression between alternate morphs relative to differences between sexes, a classic example of developmental decoupling. more...

(Submitter supplied) A major goal of molecular evolutionary biology is to understand the fate and consequences of duplicated genes. In this context, aphids are particularly intriguing because the newly sequenced pea aphid genome is characterized by extraordinarily high levels of lineage-specific gene duplication relative to other insect genomes. While analyzing the results of a microarray comparing gene expression between male, sexual female and asexual female Myzus persicae aphids, we unexpectedly found duplicated nutrient amino acid transporters highly upregulated in males. more...

(Submitter supplied) A number of genes associated with sexual traits and reproduction evolve at the sequence level faster than the majority of genes coding for non-sex-related traits. Whole genome analyses allow this observation to be extended beyond the limited set of genes that have been studied thus far. We use cDNA microarrays to demonstrate that this pattern holds in Drosophila for the phenotype of gene expression as well, but in one sex only. more...

(Submitter supplied) 5928 cDNAs from the Drosophila Gene Collection version 1.0 were amplified by PCR with universal primers and PCR products were confirmed by gel electrophoresis. Added to these was a set of 177 separately amplified controls, each of which was replicated from one to 16 times on the array. Clones for which the PCR product was absent, faint, the incorrect size, or showed multiple bands failed PCR quality control. more...

(Submitter supplied) 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 investigated the regulation of these miRNAs in different alternative morphs of the pea aphid by analysing the expression of miRNAs across the switch of reproduction mode.
