Carbon exchange between the atmosphere and the terrestrial biosphere is a key consideration in assessing the issue of global warming. Photosynthesis has come to be considered as the only process in CO_2 gas uptake to the terrestrial ecosystem. Here we have, however, discovered that Basidiomycetes(mushroom) fruiting bodies, which have no photosynthetic capabilities, selectively absorb CO_2 gas. We demonstrated that the CO_2 gas uptook abilities of L. edodes. This discovery not only compels us to re-examine the carbon balance, but also may indicate the possible existence of CO_2 fixation systems other than those involving photosynthetic organisms.

大气和陆地生物圈之间的碳交换是评估全球变暖问题的一个关键考虑因素。光合作用被认为是陆地生态系统吸收CO_2的唯一过程。然而，我们在这里发现，没有光合作用能力的担子菌（蘑菇）子实体选择性地吸收CO_2气体。结果表明，L. edodes。这一发现不仅迫使我们重新审视碳平衡，而且可能表明除了光合生物以外，还可能存在CO_2固定系统。
