Figure 1. Schematic representation of gene arrangement in CHPV and siRNAs used.

P and M genes were targeted for siRNA synthesis. The numbers were assigned arbitrarily and do not indicate location (refer table 1 for correct location of siRNA). Different siRNA used to determine tolerance for mismatches using P-2 siRNA number in parentheses represent the positions at which mismatches were incorporated (For sequence of P-2 siRNA mutants refer table 2).
