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.

正在进行巨大的努力，以选择增强资源获取和生产力的有益根系特征。这些努力通常是在不包括互惠互利的菌根伙伴关系的同时进行的，其中包括三分之二的高等植物。除非考虑这些伙伴关系的修改作用，否则这些努力可能会导致人为结果。虽然霉菌化可以显着增强植物活力，但由于广泛的“上下文依赖性”，通常很难复制结果。这项研究将确定植物和真菌特征，这些特征可以预测菌根植物如何在各种情况下受益，这将改善边际环境中的品种选择和生产力提高。
