| aphid feeding behavior in relation to potato virus y (pvy) acquisition. | potato virus y (pvy) is transmitted by aphids in a nonpersistent manner and aphid species differ in their ability to transmit pvy. during host selection, aphids will land and probe on nonhost plant species and this behavior is an important component of the epidemiology of many aphid-transmitted viruses. in this study, we hypothesized that host selection behavior varies between aphid species and the host or nonhost status of the plant and this behavior will modulate their ability to acquire pvy. ... | 2012 | 23356052 |
| characterization of arabidopsis transcriptional responses to different aphid species reveals genes that contribute to host susceptibility and non-host resistance. | aphids are economically important pests that display exceptional variation in host range. the determinants of diverse aphid host ranges are not well understood, but it is likely that molecular interactions are involved. with significant progress being made towards understanding host responses upon aphid attack, the mechanisms underlying non-host resistance remain to be elucidated. here, we investigated and compared arabidopsis thaliana host and non-host responses to aphids at the transcriptional ... | 2015 | 25993686 |
| barley transcriptome analyses upon interaction with different aphid species identifies thionins contributing to resistance. | aphids are phloem-feeding insects that cause yield loss on a wide range of crops, including cereals such as barley. while most aphid species are limited to one or few host species, some are able to reproduce on many plants belonging to different families. interestingly, aphid probing-behaviour can be observed on both host and non-host species indicating that interactions take place at the molecular level that may impact host range. here, we aimed to gain insight into the interaction of barley wi ... | 0 | 28452058 |
| comparative transcriptomics and proteomics of three different aphid species identifies core and diverse effector sets. | aphids are phloem-feeding insects that cause significant economic losses to agriculture worldwide. while feeding and probing these insects deliver molecules, called effectors, inside their host to enable infestation. the identification and characterization of these effectors from different species that vary in their host range is an important step in understanding the infestation success of aphids and aphid host range variation. this study employs a multi-disciplinary approach based on transcrip ... | 2016 | 26935069 |
| mitochondrial coi and morphological evidence for host specificity of the black cherry aphids myzus cerasi (fabricius, 1775) collected from different cherry tree species in europe (hemiptera, aphididae). | partial sequences of the mitochondrial coi gene of forty eight european and two turkish population samples of myzus cerasi from different winter hosts (prunus spp.) were subjected to phylogenetic analyses. the analysed m. cerasi samples emerged as paraphyletic relative to a myzus borealis sample used as an out-group, and formed two major clades in neighbor joining, maximum parsimony, maximum likelihood and bayesian inference trees, corresponding to subspecies living specifically on prunus avium ... | 2014 | 24715766 |
