| mining the plant-herbivore interface with a leafmining drosophila of arabidopsis. | experimental infections of arabidopsis thaliana (arabidopsis) with genomically characterized plant pathogens such as pseudomonas syringae have facilitated the dissection of canonical eukaryotic defence pathways and parasite virulence factors. plants are also attacked by herbivorous insects, and the development of an ecologically relevant genetic model herbivore that feeds on arabidopsis will enable the parallel dissection of host defence and reciprocal resistance pathways such as those involved ... | 2010 | 21073583 |
| genes involved in the evolution of herbivory by a leaf-mining, drosophilid fly. | herbivorous insects are among the most successful radiations of life. however, we know little about the processes underpinning the evolution of herbivory. we examined the evolution of herbivory in the fly, scaptomyza flava, whose larvae are leaf miners on species of brassicaceae, including the widely studied reference plant, arabidopsis thaliana (arabidopsis). scaptomyza flava is phylogenetically nested within the paraphyletic genus drosophila, and the whole genome sequences available for 12 spe ... | 2012 | 22813779 |
| pseudomonas syringae enhances herbivory by suppressing the reactive oxygen burst in arabidopsis. | plant-herbivore interactions have evolved in the presence of plant-colonizing microbes. these microbes can have important third-party effects on herbivore ecology, as exemplified by drosophilid flies that evolved from ancestors feeding on plant-associated microbes. leaf-mining flies in the genus scaptomyza, which is nested within the paraphyletic genus drosophila, show strong associations with bacteria in the genus pseudomonas, including pseudomonas syringae. adult females are capable of vectori ... | 2015 | 26205072 |
| evolution of herbivory in drosophilidae linked to loss of behaviors, antennal responses, odorant receptors, and ancestral diet. | herbivory is a key innovation in insects, yet has only evolved in one-third of living orders. the evolution of herbivory likely involves major behavioral changes mediated by remodeling of canonical chemosensory modules. herbivorous flies in the genus scaptomyza (drosophilidae) are compelling species in which to study the genomic architecture linked to the transition to herbivory because they recently evolved from microbe-feeding ancestors and are closely related to drosophila melanogaster. we fo ... | 2015 | 25624509 |
