Semi-quantitative RT-PCR data of selected plastome and nuclear encoded genes. The PCR products were separated on ethidium bromide containing agarose gels and documented electronically in UV light and analyzed densitometrically. The values are given as the logarithm of the induction factor which is calculated from the ratio of transcript level of WT and mutants at ambient 350 CO2 (hatched bars). The black bars represent logarithmic values calculated after fumigation with 0 or 2000 ppm CO2, respectively, in relation to corresponding control at 350 ppm CO2 for wt, adg1, pgr1 and vtc1. The data are means of n = 3, (◆) indicates that the SD was less than 30% of the mean value.
