Sequence analysis of FgPDK2. a Structure of nucleic acid sequence of FgPDK2. b The phylogenetic analysis of PDK2s from different fungi. The phylogenetic tree was constructed using the Neighbour-Joining method. Evolutionary analyses were conducted in MEGA4. c The multialignment of PDK2 from F. graminearum, S. cerevisiae, T. ophioglossoides and N. crassa
