Genome sequence of the pea aphid Acyrthosiphon pisum. [PDF]
PLoS Biology, 2010 Aphids are important agricultural pests and also biological models for studies of insect-plant interactions, symbiosis, virus vectoring, and the developmental causes of extreme phenotypic plasticity.

Modulation of Legume Defense Signaling Pathways by Native and Non-native Pea Aphid Clones
Frontiers in Plant Science, 2016 The pea aphid (Acyrthosiphon pisum) is a complex of at least 15 genetically different host races that are native to specific legume plants, but can all develop on the universal host plant Vicia faba.

Dopamine mediates the pea aphid wing plasticity. [PDF]
Biol Lett, 2023 Many organisms exhibit phenotypic plasticity, in which developmental processes result in different phenotypes depending on their environmental context. Here we focus on the molecular mechanisms underlying that environmental response. Pea aphids ( Acyrthosiphon pisum ) exhibit a wing dimorphism, in which pea aphid ...

The circadian and photoperiodic clock of the pea aphid. [PDF]
J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2023 AbstractThe pea aphid, Acyrthosiphon pisum, is a paradigmatic photoperiodic species that exhibits a remarkable annual life cycle, which is tightly coupled to the seasonal changes in day length. During spring and summer, characterised by longer days, aphid populations consist exclusively of viviparous females that reproduce parthenogenetically.

Pea aphid odorant-binding protein ApisOBP6 discriminates between aphid sex pheromone components, aphid alarm pheromone and a host plant volatile [PDF]
, 2023 Olfactory perception of pheromones in insects involves odorant-binding proteins (OBPs), relatively small proteins (ca.110-240 amino acid residues) that can bind reversibly to behaviourally active olfactory ligands.

Transcriptomic basis of sex loss in the pea aphid. [PDF]
BMC GenomicsAbstract Background Transitions from sexual to asexual reproduction are common in eukaryotes, but the underlying mechanisms remain poorly known. The pea aphid—Acyrthosiphon pisum—exhibits reproductive polymorphism, with cyclical parthenogenetic and obligate parthenogenetic lineages, offering an opportunity to decipher ...

Effect of selenium on alleviating oxidative stress in pea leaves caused by pea aphid feeding
Journal of Plant Protection Research, 2021 The aim of this study was to evaluate the antioxidant effect of selenium in Pisum sativum L. plants pre-treated with sodium selenite or sodium selenate at a concentration of 10 and 20 μM, and then colonized by pea aphid Acyrthosiphon pisum (Harris). It

Insects, 2023 In recent years, pea aphids have become major pests of alfalfa. Our previous study found that “Gannong 5” is a highly aphid-resistant alfalfa variety and that “Lie Renhe” is a susceptible one.

To feed or not to feed: plant factors located in the epidermis, mesophyll, and sieve elements influence pea aphid's ability to feed on legume species. [PDF]
PLoS ONE, 2013 The pea aphid (Acyrthosiphon pisum Harris), a legume specialist, encompasses at least 11 genetically distinct sympatric host races. Each host race shows a preference for a certain legume species.
