Cold acclimation and BnCBF17-over-expression enhance photosynthetic performance and energy conversion efficiency during long-term growth of Brassica napus under elevated CO2 conditions.
The effects of cold acclimation and long-term elevated CO2 on photosynthetic performance of wild-type (WT) and BnCBF17-over-expressing line of Brassica napus cv.
Compared with non-acclimated WT, the BnCBF17-OE grown at 20 °C mimicked the effects of cold acclimation on WT B. napus with respect to compact dwarf phenotype and increased rates of light-saturated CO2 assimilation and photosynthetic electron transport.
BnCBF17-over-expression and cold acclimation maintain enhanced energy conversion efficiency and reduced sensitivity to feedback-limited photosynthesis during long-term growth of B. napus under elevated CO2.
