Arbuscular mycorrhizal fungi (AMF) contribute predominantly to soil organic matter by creating a sink demand for plant C and distributing to below-ground hyphal biomass. The extra-radical hyphae along with glomalin-related soil protein significantly influence the soil carbon dynamics through their larger extent and turnover period need to discuss. The role of AMF is largely overlooked in terrestrial C cycling and climate change models despite their greater involvement in net primary productivity augmentation and further accumulation of this additional photosynthetic fixed C in the soil. However, this buffering mechanism against elevated CO condition to sequester extra C by AMF can be described only after considering their potential interaction with other microbes and associated mineral nutrients such as nitrogen cycling. In this article, we try to review the potential of AMF in C sequestration paving the way towards a better understanding of possible AMF mechanism by which C balance between biosphere and atmosphere can be moved forward in more positive direction.
丛枝菌根真菌(AMF)通过为植物 C 创造一个汇需求并分配到地下菌丝生物量,主要为土壤有机质做出贡献。额外的根外菌丝和与球囊霉素相关的土壤蛋白通过其更大的范围和周转期显著影响土壤碳动态,需要加以讨论。尽管 AMF 在净初级生产力增加和进一步积累土壤中这种额外光合作用固定的 C 方面的作用更大,但它们在陆地 C 循环和气候变化模型中的作用在很大程度上被忽视了。然而,只有在考虑到它们与其他微生物和相关矿物质养分(如氮循环)的潜在相互作用后,才能描述 AMF 对升高的 CO 条件下通过缓冲机制隔离额外 C 的作用。在本文中,我们试图综述 AMF 在碳封存方面的潜力,为更好地理解 AMF 机制铺平道路,从而使生物圈和大气之间的碳平衡朝着更积极的方向发展。
