Much attention is focused today on predicting how plants will respond to anticipated changes in atmospheric composition and climate, and in particular to increases in CO(2) concentration. Here we review the long-term global fluctuations in atmospheric CO(2) concentration as a framework for understanding how current trends in atmospheric CO(2) concentration fit into a selective, evolutionary context. We then focus on an integrated approach for understanding how gas exchange metabolism responds to current environmental conditions, how it previously responded to glacial-interglacial conditions, and how it may respond to future changes in atmospheric CO(2) concentration.
如今，许多注意力都集中在预测植物将如何应对大气成分和气候的预期变化上，尤其是二氧化碳浓度的增加。在此，我们回顾大气二氧化碳浓度的长期全球波动情况，以此作为理解当前大气二氧化碳浓度趋势如何融入一个选择性的进化背景的框架。然后，我们专注于一种综合方法，以理解气体交换代谢如何对当前环境条件做出反应，它以前如何应对冰期 - 间冰期条件，以及它可能如何应对未来大气二氧化碳浓度的变化。
