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.

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:Myzus persicae (green peach aphid) feeding on Arabidopsis thaliana induces a defense response, quantified as reduced aphid progeny production, in infested leaves but not in other parts of the plant. Similarly, infiltration of aphid saliva into Arabidopsis leaves causes only a local increase in aphid resistance. Further characterization of the defense-eliciting salivary components indicates that Arabidopsis recognizes a proteinaceous elicitor with a size between 3 to 10 kD. Genetic analysis using well-characterized Arabidopsis mutant shows that saliva-induced resistance against M. persicae is independent of the known defense signaling pathways involving salicylic acid, jasmonate, and ethylene. Among 78 Arabidopsis genes that were induced by aphid saliva infiltration, 52 had been identified previously as aphid-induced, but few are responsive to the well-known plant defense signaling molecules salicylic acid and jasmonate. Quantitative PCR analysis confirms expression of saliva-induced genes. In particular, expression of a set of O-methyltransferases, which may be involved in the synthesis of aphid-repellent glucosinolates, was significantly up-regulated by both M. persicae feeding and treatment with aphid saliva. However, this did not correlate with increased production of 4-methoxyindol-3-ylmethylglucosinolate, suggesting that aphid salivary components trigger an Arabidopsis defense response that is independent of this aphid-deterrent glucosinolate.

Project description:The peach-potato aphid, Myzus persicae, is a globally pervasive crop pest, primarily reproducing clonally, allowing single females to rapidly generate exact copies of themselves. Moreover, its extreme polyphagy enables it to colonize over 400 plant species. Studies on the genetic underpinnings of M. persicae colonization have highlighted the differential expression and transcriptional regulation of a family of cysteine proteases, Cathepsin B (CathB), in response to various plant species. Among all M. persicae CathB proteins, CathB6 is most highly expressed in aphids on A. thaliana and most abundantly detected in M. persicae oral secretions. To investigate the potential plant target of CathB6 in A. thaliana, we conducted TurboID-based proximity labelling and MS (PL-MS).
