Characterization of Nicotiana attenuata plants with reduced expression of lectin receptor kinase 1 (ir-lecRK1 plants).

ABSTRACT: Identification of transcripts that change expression in Nicotiana attenuata plants with reduced expression of lectin receptor kinase 1 after elicitation with oral secretions of Manduca sexta larvae. Gene expression in leaves of Nicotiana attenuata wild type and ir-lecRK1 plants was measured at 1 hour after elicitation with oral secretions of Manduca sexta larvae. Three independent experiments were performed with wild type plants and three independent experiments were performed with ir-lecRK1 plants. A total of 148 genes were identified as differentially regulated in ir-lecRK1 plants compared to wild type plants.

Nicotiana attenuata has the capacity to respond specifically to herbivory by its natural herbivore, Manduca sexta, through the perception of elicitors in larval oral secretions. We demonstrate that Lectin receptor kinase 1 (LecRK1) functions during M. sexta herbivory to suppress the insect-mediated inhibition of jasmonic acid (JA)-induced defense responses. Gene function analysis performed by reducing LecRK1 expression in N. attenuata by both virus-induced gene silencing and inverted repeated RN  ...[more]
