The 1914bp cDNA sequence of phosphopyruvate hydratase was obtained.
Phosphopyruvate hydratase was highly expressed in muscle of M. japonicus only.
WSSV or Vibrio alginolyticus infection will change phosphopyruvate hydratase expression tempestuously.
Phosphopyruvate hydratase is vital for WSSV infection and the dead time of WSSV-infected shrimp was significantly delayed by the gene silencing.
