Figure 2

The position of the two 207-bp insertions in the IRS and TRS regions in DEV Clone-03 strain comparing to the VAC strain. The red and blank arrows indicate the main genes in the IRS and TRS regions. The gray boxes indicate the interval between the ICP4 and US1 genes. The blue and green boxes with dashed lines indicate the 207-bp fragment that was deleted from the IRS and TRS regions in the published VAC strain, respectively. Letters a and b indicate the fragment in the IRS and TRS regions, respectively. The sequences of the two fragments are listed in the boxes at the bottom.
