Grain filling stage is the key period for wheat kernel weight.However,wheat often encounters high light intensity combined with high temperature at this stage.The combined stresses result in the decline of photosynthetic rate,which ultimately causes yield loss.In our previous study,we found that a wheat variety Zhengmai 7698 showed strong tolerance to high light intensity and high temperature.In order to illuminate the physiological mechanism of high light intensity and high temperature co-stress tolerance ...
