From: Changes in SBPase activity influence photosynthetic capacity, growth, and tolerance to chilling stress in transgenic tomato plants

Figure 3

Diurnal changes in SlSBPase mRNA abundance, SBPase activity, CO2 assimilation rate, PFD and air temperature measured in greenhouse conditions on three consecutive sunny days.

All measurements were done on 20-leaf tomato plants. (a) SlSBPase mRNA abundance was analyzed by quantitative real-time PCR using total RNA isolated from the fully expanded leaves (leaf no. 13–15 from base) at 2-h intervals. (b) Diurnal variation of PFD in greenhouse. (c) Diurnal variation of air temperature in greenhouse. (d) SBPase activity was assayed using the same tissues for SlSBPase mRNA analysis. (e) Measurements of CO2 assimilation rate were made on the fully expanded leaves (leaf no. 13–15) at 2-h intervals. (f) CO2 assimilation rates were plotted against levels of SBPase activity, showing the correlation between them. The results are the means ± SDs (n = 4).
