Fig. 5.

Total seed yield (g m⁻²) of the wild-type (WT) and bifunctional FBP/SBPase-expressing (FS) plants in comparison in the three growing seasons. Plants were grown under the ‘Ac’ (400 μmol mol⁻¹ [CO₂], control temperature), ‘Ah’ (400 μmol mol⁻¹ [CO₂], heated +3.5 °C), ‘Ec’ (600 μmol mol⁻¹ [CO₂], control temperature), and ‘Eh’ (600 μmol mol⁻¹ [CO₂], heated +3.5 °C) treatments at the Soy-T-FACE experiment. Plants were harvested along a total row length of 1 m in 2013 (A) and of 3.2 m in 2014 (B) and 2015 (C), and seed yield was converted into g m⁻². Error bars are ±SE of the LS means estimate as derived from the complete block ANOVA (Table 3) Symbols mark significant differences between the WT (empty bars) and FS (gray bars) (* <0.05, ** <0.01).
