Drought has negative consequences on aphid fitness and plant vigor: Insights from a meta-analysis. [PDF]

Ecol Evol, 2021
Using meta‐analysis, we provide the first comprehensive analysis of drought stress on aphid fitness, showing negative effects across different host plant families, aphid tribes, and geographic regions. These negative effects were observed for different aphid fitness parameters and host specialisms and likely result from drought‐induced reduction in ...

Elucidation of host and symbiont contributions to peptidoglycan metabolism based on comparative genomics of eight aphid subfamilies and their Buchnera. [PDF]

PLoS Genetics, 2022
Pea aphids (Acyrthosiphon pisum) are insects containing genes of bacterial origin with putative functions in peptidoglycan (PGN) metabolism. Of these, rlpA1-5, amiD, and ldcA are highly expressed in bacteriocytes, specialized aphid cells that harbor the ...

Chromosome-level genome assembly for the horned-gall aphid provides insights into interactions between gall-making insect and its host plant. [PDF]

Ecol Evol, 2022
The genome of a galling aphid Schlechtendalia chinensis is 271.52 Mb. Nine‐seven percent of the assembled sequences were anchored onto 13 chromosomes. A total of 14,089 protein‐coding genes were predicted and 35 genes encoding salivary gland proteins have potential roles in gall formation and plant defense suppression.

The phylogenetic and evolutionary analyses of detoxification gene families in Aphidinae species. [PDF]

PLoS ONE, 2022
Detoxification enzymes play significant roles in the interactions between insects and host plants, wherein detoxification-related genes make great contributions. As herbivorous pests, aphids reproduce rapidly due to parthenogenesis.
