The western corn rootworm (WCR), Diabrotica virgifera virgifera, is a major corn pest in the United States and Europe. WCR has developed resistance to multiple management strategies, including Cry proteins. Even though the biology and ecology have been thoroughly studied in WCR, their genome and molecular mechanisms are understudied. This work focuses on the ubiquitous enzyme deoxyuridine triphosphatase (dUTPase) encoded by the DUT gene. dUTPase hydrolyzes dUTP into dUMP and pyrophosphate. It contributes to genome stability by keeping the uracil-to-thymine ratio at a certain level. In WCR, two dUTPase isoforms were predicted using transcriptome analyses. These two potential isoforms …
