The Impact of Oulema melanopus-Associated Bacteria on the Wheat Defense Response to the Feeding of Their Insect Hosts.

ABSTRACT: Wheat production is threatened by the destructive effects of numerous pests, including Oulema melanopus (cereal leaf beetle, CLB). Both adults and larvae of CLB damage grain crops, but the target of insecticide treatments are the larvae. Insect-associated bacteria are important for many of the insects' life processes and may also modulate plant defense responses to feeding of their insect host. The aim of our study was to elucidate the early wheat plants' reaction to this herbivore feeding and to disclose the CLB-associated bacteria modulation of the wheat-insect interactions. Transcriptome analyses were performed for the leaves wounded mechanically and by feeding of the CLB larvae as well as for the distal leaves to study both, the plant's local and systemic response.
