Plant immunity in plant–aphid interactions
Aphids are economically important pests that cause extensive feeding damage and transmit viruses. While some species have a broad host range and cause damage to a variety of crops, others are restricted to only closely related plant species. While probing and feeding aphids secrete saliva, containing effectors, into their hosts to manipulate host cell processes and promote infestation. Aphid ef...
متن کاملHost Plant Specialization in the Sugarcane Aphid Melanaphis sacchari
Most aphids are highly specialized on one or two related plant species and generalist species often include sympatric populations adapted to different host plants. Our aim was to test the hypothesis of the existence of host specialized lineages of the aphid Melanaphis sacchari in Reunion Island. To this end, we investigated the genetic diversity of the aphid and its association with host plants...
متن کاملPlant-derived differences in the composition of aphid honeydew and their effects on colonies of aphid-tending ants
In plant-ant-hemipteran interactions, ants visit plants to consume the honeydew produced by phloem-feeding hemipterans. If genetically based differences in plant phloem chemistry change the chemical composition of hemipteran honeydew, then the plant's genetic constitution could have indirect effects on ants via the hemipterans. If such effects change ant behavior, they could feed back to affect...
متن کاملAngiotensin-converting enzymes modulate aphid–plant interactions
Angiotensin-converting enzymes (ACEs) are key components of the renin-angiotensin system in mammals. However, the function of ACE homologs in insect saliva is unclear. Aphids presumably deliver effector proteins via saliva into plant cells to maintain a compatible insect-plant interaction. In this study, we showed that ACE modulates aphid-plant interactions by affecting feeding behavior and sur...
متن کاملHost-plant genotypic diversity and community genetic interactions mediate aphid spatial distribution
Genetic variation in plants can influence the community structure of associated species, through both direct and indirect interactions. Herbivorous insects are known to feed on a restricted range of plants, and herbivore preference and performance can vary among host plants within a species due to genetically based traits of the plant (e.g., defensive compounds). In a natural system, we expect ...
