*Numbers within primer names represent the primer positions. An F after the primer position stands for sense primers while R stands for anti-sense primers.
**SP6 and T7 are tag sequences attached at the 5′ end of all PCR primers used in this study. SP6 and T7 primers were used to sequence PCR fragments.
