Project description:The aim of this experiment was to compare the transciptome of the peach-potato aphid (Myzus persicae) clone 4106a (a laboratory insecticide-susceptible standard collected from potato in Scotland in 2000) with clone 5191A (an insecticide resistant aphid clone collected from tobacco in Greece in 2007) to identify which genes are over or underexpressed in the resistant phenotype.

Two-condition experiment, 4106a vs. 5191a Myzus persicae clones. Biological replicates: 4 pools of RNA extracted from ten 15 day old aphids of each clone. Technical Replicates: Two technical reps incorporating a dye swap. Total replication: eight replicates for each clone.

Project description:The aim of this experiment was to compare the transciptome of the peach-potato aphid (Myzus persicae) clone 4106a (a laboratory insecticide-susceptible standard collected from potato in Scotland in 2000) with clone FRC (an insecticide resistant aphid clone collected from peach in France in 2009) to identify which genes are over or underexpressed in the resistant phenotype. The custom microarray used in this study was designed using the Agilent eArray platform (Agilent Technologies) by the Georg Jander Lab and is based on a previously described array containing probes for >10, 000 M. persicae unigenes produced by Sanger sequencing (Ramsey, Wilson et al. 2007) augmented with an additional 30, 517 probe set designed on EST unigene sequences identified in a 454 sequencing project (Ramsey, Rider et al. 2010). The final slide layout consists of four arrays of 45, 220 60-mer probes and these are produced by Agilent by in situ oligonucleotide synthesis. References: Ramsey, J. S., D. S. Rider, et al. (2010).

Project description:The green peach aphid/peach-potato aphid Myzus persicae can colonize hundreds of plant species, an ability that is in part due to the delivery of saliva proteins – often referred to as effectors – into the host plant that suppress plant defence. As a generalist herbivore with a remarkable ability to colonize new host plants M. persicae represents an outstanding model system for studying the molecular mechanisms underlying plant-insect interactions. Recent advancements in mass spectrometry instrumentation and database search software along with a new high-quality reference genome assembly for M. persicae and a simplified method for improved aphid saliva recovery, collectively enhance the detection of saliva proteins with unprecedented sensitivity and specificity.

Project description:In most aphid species, facultative parthenogenetic reproduction allows rapid growth and formation of large single-genotype colonies. Upon predator attack, individual aphids emit an alarm pheromone to warn the colony of this danger. (E)-beta-farnesene (EBF) is the predominant constituent of the alarm pheromone in Myzus persicae (green peach aphid) and many other aphid species. Continuous exposure to alarm pheromone in aphid colonies raised on transgenic Arabidopsis thaliana plants that produce EBF leads to habituation of the aphid population. Whereas naïve aphids are repelled by EBF, habituated aphids show no avoidance response. Individual aphids from the habituated colony can revert back to being EBF-sensitive in three generations, indicating that this behavioral change is not caused by a genetic mutation. Instead, DNA microarray experiments comparing gene expression in naïve and habituated aphids treated with EBF demonstrate an almost complete desensitization in the transcriptional response to EBF. Furthermore, EBF-responsive aphids, but not habituated aphids show significantly lower reproduction in the presence of EBF. Although both naïve and habituated aphids emit EBF upon damage, EBF-responsive aphids display a higher survival rate in the presence of coccinellid predators and thus outperform habituated aphids that do not show an avoidance response. These results provide direct evidence that aphid perception of conspecific alarm pheromone aids in predator avoidance and thereby bestows fitness benefits in survivorship and fecundity. Although habituated M. persicae have equal fecundity on control and EBF-producing plants, such transgenics may have practical applications in agriculture because of increased predation of habituated aphids. Log fold-changes (LogFC) were computed and contigs with P-values ≤ 0.05 were considered to be differentially expressed (see Supplementary file at foot of this record).
