植物通过光合作用固定二氧化碳（CO2）将光子转化为碳水化合物资源，这些碳水化合物资源被同化并从光合源分配到库组织。从光合作用中获得的化学能包括ATP和NADPH，它们与糖沿着对生物合成过程、细胞增殖、生物量生产和生殖健康至关重要。与所有真核生物一样，植物依赖于氧气（O2）通过线粒体的有氧呼吸有效生产ATP。因此，O2是至关重要的碳水化合物，脂质和蛋白质的有效categorization成化学能在叶片中的光和暗，以及在水槽组织。在这个焦点问题中，许多评论和研究文章探讨了从细胞到整个植物水平的光，O2和能量代谢的整合。文章分析了分子，生化，生理和发育机制，有助于植物的能量平衡。一个反复出现的主题是光，O2和糖传感与信号转导和基因调控的整合，导致代谢和发育可塑性，最大限度地提高可用能量的增长。这一知识扩大了提高光合效率和调整能量分配以最大限度地提高作物产量的机会。
Plants are exquisite in their capacity to convert photons of light through photosynthetic carbon dioxide (CO2) fixation into carbohydrate resources that are assimilated and partitioned from photosynthetic source to sink tissues. The chemical energy gained from photosynthesis includes ATP and NADPH that along with sugars are vital to biosynthetic processes, cell proliferation, biomass production, and reproductive fitness. As in all eukaryotes, plants are dependent upon dioxygen (O2) for efficient production of ATP through aerobic respiration by mitochondria. Therefore, O2 is crucial for the efficient catabolism of carbohydrates, lipids, and protein into chemical energy in leaves in the light and darkness, as well as in sink tissues. In this Focus Issue, numerous reviews and research articles explore the integration of light, O2, and energy metabolism from the cellular to the whole-plant level. The articles analyze molecular, biochemical, physiological, and developmental mechanisms that contribute to the plant’s energy balance. A recurrent theme is the integration of light, O2, and sugar sensing with signal transduction and gene regulation, resulting in metabolic and developmental plasticity that maximizes available energy for growth. This knowledge expands opportunities to enhance photosynthetic efficiency and finetune energy allocation to maximize yields of crops.
