碳有效性影响纯培养中外生菌根真菌菌丝体化学组成的已大物种特异性差异。

尽管外生菌根（ECM）对土壤有机质过程的贡献越来越受到关注，但人们对物种之间化学成分的根本差异以及碳（C）有效性如何影响知之甚少。在这里，我们使用傅里叶变换红外光谱（FTIR）研究了在三种不同的C:N比（10:1、20:1和40:1）的纯培养物中生长的16个物种（包括19个分离株）的化学结构如何变化。我们假设碳有效性直接影响化学成分，预计碳有效性的增加会导致菌丝中更多的碳水化合物和更少的蛋白质。ECM物种（R2 = 0.873和P = 0.001）和化学成分的大物种特异性差异。化学成分也随着碳的可用性而发生显著变化，碳的增加导致许多物种（但不是所有物种）的多糖和蛋白质增加。了解化学成分如何随着碳有效性的改变而变化，是了解它们在有机物积累和分解中的作用的第一步。

期刊介绍： Mycorrhiza is an international journal devoted to research into mycorrhizas - the widest symbioses in nature, involving plants and a range of soil fungi world-wide. The scope of Mycorrhiza covers all aspects of research into mycorrhizas, including molecular biology of the plants and fungi, fungal systematics, development and structure of mycorrhizas, and effects on plant physiology, productivity, reproduction and disease resistance. The scope also includes interactions between mycorrhizal fungi and other soil organisms and effects of mycorrhizas on plant biodiversity and ecosystem structure. Mycorrhiza contains original papers, short notes and review articles, along with commentaries and news items. It forms a platform for new concepts and discussions, and is a basis for a truly international forum of mycorrhizologists from all over the world.
