MetabolomicsPrevious infestation by conspecifics leads to a transient increase of the performance of Sitobion avenae aphids on wheat leaves

1. The ecological niche of aphids is largely defined by the phloem sap of plants, which they consume. Previous studies revealed that aphids may change the phloem sap metabolome and that a previous aphid infestation may benefit them. As aphids reproduce parthenogenetically, the performance and pre...

MetabolomicsElevated CO2 and virus infection impacts wheat and aphid metabolism

INTRODUCTION: The aphid Rhopalosiphum padi L. is a vector of Barley yellow dwarf virus (BYDV) in wheat and other economically important cereal crops. Increased atmospheric CO2 has been shown to alter plant growth and metabolism, enhancing BYDV disease in wheat. However, the bioch...

MetabolomicsLipidomics and RNA-Seq Study of Lipid Regulation in Aphis gossypii parasitized by Lysiphlebia japonica
The cotton-melon aphid, Aphis gossypii Glover, is a major insect pest worldwide. Lysiphlebia japonica (Ashmead) is an obligate parasitic wasp of A. gossypii, and has the ability to regulate lipid metabolism of the cotton-melon aphid. Lipids are known to play critical roles in energy homeostasis, mem...

TranscriptomicsmRNA time-course transcription profiling of bacteriocytes and gut tissue of pea aphids reared on standard artificial diet (AP3) and artificial diet depleted in Tyr and Phe (YFØ)
Tyrosine (Tyr, Y) and phenylalanine (Phe, F) synthesis is shared by the pea aphid and its symbiont Buchnera aphidicola.These aromatic amino acids are essential for the pea aphid growth and development. To characterize the molecular mechanisms, at gene transcriptional level, underlying this symbiotic...

TranscriptomicsTranscriptomic and proteomic analyses of seasonal photoperiodism in the pea aphid
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...

TranscriptomicsNovel male-biased expression in paralogs of the aphid slilmfast nutrient amino acid transporter expansion
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 relativ...

TranscriptomicsGene expression profiling of 5 pea aphid morphs
Purpose: Identify differentially expressed genes between 5 pea aphid morphs Methods: Collected whole bodies of 30 adult aphids of each of the five pea morphs and three clones (total of 15 samples) 5 pea aphid morphs * 3 genotypes = 15 samples

TranscriptomicsZea mays B73 corn-leaf aphids feeding time-course raw sequence reads
As a response to insect attack, maize (Zea mays) has inducible defenses that involve large changes in gene expression and metabolism. Piercing/sucking insects such as corn leaf aphids (Rhopalosiphum maidis) cause direct damage by acquiring phloem nutrients as well as indirect damage through the tran...

ProteomicsBacteria Associated with Russian Wheat Aphid (Diuraphis noxia) Enhance Aphid Virulence to Wheat
Phenotypic responses to biotic stresses are often studied as the interactions between two species; however, in the phytobiome, these responses frequently result from complex interactions involving several organisms. Here, we show that variation in chlorosis caused by Russian wheat aphid (Diuraphis n...
