 Plant physiologists are scrambling to understand the effects of rising temperatures on corn, but studying plants in the field or lab can be complicated and time-consuming. Until now. There is a multi-organ metabolic computer model. The model, the largest ever created for a plant system, allows scientists to predict the effects of different stressors on the metabolism of corn plants. High temperatures can affect corn in many ways. Photosynthesis can decline, leaves produce less carbohydrates, kernels accumulate less starch, lignin production in stocks drops, and more.
