In vitro transcription of four wild-type Arabidopsis rbcS genes. The relative transcription levels of four Arabidopsis rbcS genes (rbcS-1A, 1B, 2B, and 3B) were compared with in vitro transcription of TNE, ANE-D, and ANE-L, respectively. The CaMV 35S promoter was used as a control. Three independent assays were performed for each construct, and error bars indicate se.
