AR Promoter A1-A3

This part is a part of the Chlamy-HUB-Collection. Another strong constitutive promoter is the AR promoter that is composed of HSP70A and RBCS2 building a tandem promoter. Therefore the HSP70A (A) promoter is fused upstream of another promoter resulting in a stronger transgene expression (Schroda et al. 2000). The combination of the HSP70A (A) promoter and the RBCS2 (R) promoter building PAR has the positive effect that transcriptional gene silencing (TGS) is strongly reduced making this promoter popular for transgene expression (Schroda et al. 2002). This part was designed for C. reinhardtii
