Schematic representation of primers design for experimental analyses by RT-PCR or qPCR. A: Representation of polycistronic unit 10 with the terminator w_014 (hairpin). B: Enlargement of highlighted region in A, showing the position of primers for terminator validation. Black arrows Te.F, Te.R, Ex.F and Ex.R represent the primers U.10.Te.F, U.10.Te.R, U.10.Ex.F and U.10.Ex.R, respectively. (U.10 – polycistronic unit 10, Te – terminator, Ex – external, F – forward and R – reverse).
