Exploring Rice Photoprotection— Protein evidence for photosynthesis research
Faster photoprotection recovery does not always mean better crop growth.
In Plant, Cell & Environment, Zheng and colleagues investigated rice engineered to express Arabidopsis VDE, PsbS, and ZEP—the VPZ combination.
The transgenic lines showed faster relaxation of non-photochemical quenching (NPQ), yet exhibited reduced photosynthetic capacity, growth, and biomass accumulation under the tested conditions. These findings highlight the importance of evaluating photoprotection alongside carbon assimilation and whole-plant performance.
PhytoAB antibodies helped verify expression of the introduced Arabidopsis proteins by Western blotting:
Both antibodies were used at a 1:2,000 dilution. Figure 1D presents the immunoblots confirming AtPsbS and AtZEP accumulation in the transgenic rice lines.
