The mycorrhizal symbiosis between fungi and plants is among the oldest, ubiquitous and most important interactions in terrestrial life on Earth. Carbon (C) transfer across a common mycorrhizal network (CMN) was demonstrated over half a century ago in the lab ( Reid & Woods, 1969), and later in the field ( Simard ., 1997a). Recent years have seen ample progress in this research direction, including evidence for ecological significance of carbon transfer ( Klein ., 2016). Furthermore, specific cases where the architecture of mycorrhizal networks have been mapped ( Beiler ., 2015) and CMN-C transfer from mature trees to seedlings has been demonstrated ( Orrego, 2018) have suggested that trees in forests are more connected than once thought ( Simard, 2021). In a recent , Karst . (2023) offered a valuable critical review warning of over-interpretation and positive citation bias in CMN research. It concluded that while there is evidence for C movement among plants, the importance of CMNs remains unclear, as noted by others too ( Henriksson ., 2023). Here we argue that while some of these claims are justified, factual evidence about belowground C transfer across CMNs is solid and accumulating.
真菌与植物之间的菌根共生关系是地球上陆地生命中最古老、最普遍且最重要的相互作用之一。半个多世纪前就在实验室中证实了碳（C）在共同菌根网络（CMN）中的转移（Reid & Woods，1969），后来在野外也得到了证实（Simard等，1997a）。近年来，这一研究方向取得了长足进展，包括碳转移生态意义的证据（Klein等，2016）。此外，已绘制菌根网络结构的具体案例（Beiler等，2015）以及已证实在成熟树木与幼苗之间存在CMN-C转移（Orrego，2018），这表明森林中的树木之间的联系比以往认为的更为紧密（Simard，2021）。最近，Karst等（2023）进行了一次有价值的批判性综述，警告了CMN研究中存在的过度解读和正向引用偏差。其结论是，虽然有证据表明植物之间存在碳转移，但正如其他人也指出的那样（Henriksson等，2023），CMN的重要性仍不明确。在这里，我们认为，虽然其中一些说法有一定道理，但关于地下碳通过CMN转移的事实证据确凿且不断积累。
