Potato virus Y infection hinders potato defence response and renders plants more vulnerable to Colorado potato beetle attack


ABSTRACT: In the present study molecular interactions between potato plants, Colorado potato beetle (CPB) larvae and Potato virus YNTN (PVYNTN) were investigated by analyzing gene expression in potato leaves. mRNA samples of secondary PVYNTN-infected (CPB_PVY) and healthy potato plants (CPB_H) cultivar Igor and of RNAi coi1-silenced (CPB_coi1) and non-transformed (CPB_NT) potato plants cultivar Desiree collected 24 h post CPB infestation and respective control non-infested samples (CONT_PVY, CONT_H, CONT_coi1, CONT_NT).

In the field, plants are challenged by more than one biotic stressor at the same time. In this study, the molecular interactions between potato (Solanum tuberosum L.), Colorado potato beetle (Leptinotarsa decemlineata Say; CPB) and Potato virus Y(NTN) (PVY(NTN) ) were investigated through analyses of gene expression in the potato leaves and the gut of the CPB larvae, and of the release of potato volatile compounds. CPB larval growth was enhanced when reared on secondary PVY(NTN) -infected plants  ...[more]
