Adapting crops to warmer growing season temperatures is a major challenge in mitigating the impacts of climate change on crop production. While nearly all processes in plants are impacted by above-optimum temperatures, the impact of heat stress on photosynthetic processes stand out for their centrality. Therefore, understanding and improving photosynthetic responses to changing environmental conditions is crucial in developing high-yielding resilient crops. This talk provides an update on transgenic strategies that show promise in improving the high-temperature tolerance of photosynthesis.
