Massive efforts are underway to select beneficial root traits that enhance resource acquisition and productivity. These efforts are usually conducted while excluding mutually beneficial mycorrhizal partnerships, which include two-thirds of higher plants. These efforts are likely to lead to artifactual outcomes unless the modifying effects of these partnerships are considered. While mycorrhization can substantially enhance plant vigour, results are often difficult to replicate due to widespread 'context-dependence'. This research will identify plant and fungal traits that predict how mycorrhizal plants benefit under a variety of contexts, which will improve varietal selection and productivity gains in marginal environments.

人们正在进行大量努力来选择有益的根性状，以提高资源获取和生产力。这些努力通常是在排除互利的菌根伙伴关系的情况下进行的，其中包括三分之二的高等植物。除非考虑这些伙伴关系的改变效应，否则这些努力可能会导致人为结果。虽然菌根化可以显着增强植物活力，但由于广泛的“环境依赖性”，结果通常难以复制。这项研究将确定植物和真菌特征，预测菌根植物如何在各种环境下受益，这将改善边缘环境中的品种选择和生产力提高。
