Fig. 5From: Genetic determinants controlling maize rubisco activase gene expression and a comparison with rice counterpartsActivity of different types of RCA promoters. a Schematic diagrams of the dual luciferase assay vector. REN, Renilla luciferase; LUC, firefly luciferase; ter, terminator. b Ratios of LUC and REN activity in maize and rice protoplasts transformed with recombinant plasmids containing different types of ZmRCAβ and OsRCA promoters and negative control. c Ratios of LUC and REN activity in tobacco (Nicotiana benthamiana) leaves transformed with recombinant plasmids containing different types of ZmRCAβ and OsRCA promoters and negative control. Multiple comparison of phenotypic data was performed using LSD test. Different English alphabet means significant difference at P < 0.05Back to article page
