Phosphoprotein Contributes to the Thermostability of Newcastle Disease Virus

Figure 1

Schematic representation of strategies to exchange the P gene between the pNDV4C and pLaSo vectors. White and dark bars represent genes of the NDV4-C and LaSota strain, respectively. Unique restriction sites SwaI and PmeI were created on both pNDV4C and pLaSo cDNAs to exchange the P gene.
