Accelerated evolution of morph-biased genes in pea aphids.

Molecular biology and evolution 20140426 8

Phenotypic plasticity, the production of alternative phenotypes (or morphs) from the same genotype due to environmental factors, results in some genes being expressed in a morph-biased manner. Theoretically, these morph-biased genes experience relaxed selection, the consequence of which is the buildup of slightly deleterious mutations at these genes. Over time, this is expected to result in increased protein divergence at these genes between species and a signature of relaxed purifying selection ...[more]

Phenotypic plasticity in the pea aphid Acyrthosiphon pisum: miRNA expression

Project description: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. An array including the 155 aphid microRNAs was designed in order to follow the expression of aphid microRNAs during the modification of reproduction mode of the pea aphid

Project description:Salicylic acid (SA) and jasmonic acid (JA) fulfill key signaling functions in plant responses to herbivores. However, the mechanisms that facilitate systemic signaling in response to phloem-feeding insects remain poorly defined. Rapid local and systemic transcriptome reprogramming patterns observed in Arabidopsis thaliana following infestation by the green peach aphid (Myzus persicae Sulzer) identify abscisic acid (ABA) and redox-signalling as key factors in the transmission of signals from local to systemic leaves. Moreover, aphid fecundity was increased in mutants that were defective in ABA-signaling through ABA-INSENSITIVE 4 and show constitutive up-regulation of SA- and JA-mediated defense pathways. Conversely, aphid fecundity was decreased and aphid vigor was impaired on vitamin C2 mutants that are defective in the major low molecular weight antioxidant of plant cells, ascorbic acid and show constitutive up-regulation of redox defense and SA-mediated pathways but reduced up-regulation of JA-mediated pathways. Crossing vtc2 with abi4 restored the wild type sensitivity to aphids. Hence aphid fecundity was attenuated by low ascorbate in a manner that was dependent on the functions of the ABI4 transcription factor. ABI4 is not only an important regulator of systemic defenses against aphids but it makes a significant contribution to the SA-mediated repression of JA signaling.
