title: Herbivory responsive C2H2 zinc finger transcription factor protein StZFP2 from potato.
abstract: While C2H2 zinc finger transcription factors (TF) are often regulated by abiotic stress, their role during insect infestation has been overlooked. This study demonstrates that the transcripts of the zinc finger transcription factors StZFP1 and StZFP2 are induced in potato (Solanum tuberosum L.) upon infestation by either the generalist tobacco hornworm (THW, Manduca sexta L.) or the specialist Colorado potato beetle (CPB, Leptinotarsa decemlineata Say). StZFP1 has been previously characterized as conferring salt tolerance to transgenic tobacco and its transcript is induced by Phytophthora infestans and several abiotic stresses. StZFP2 has not been characterized previously, but contains the hallmarks of a C2H2 zinc finger TF, with two conserved zinc finger domains and DLN motif, which encodes a transcriptional repressor domain. Expression studies demonstrate that StZFP2 transcript is also induced by tobacco hornworm and Colorado potato beetle. These observations expand the role of the C2H2 transcription factor in potato to include the response to chewing insect pests.
