Root‐associated fungi provide a range of functions for their hosts and can strongly influence plant structural and physiological traits. A better understanding of intraspecific variation in plant‐fungal relationships is needed, particularly in non‐model systems of high ecological importance, where these interactions may influence community and ecosystem processes. Hughes et al. conducted a common garden inoculation experiment to test the effects of a marine dark septate endophyte fungus (Lulwoana sp.) on the traits of different genotypes of the host salt marsh plant species Spartina alterniflora. Lulwoana affected S. alterniflora morphology, biomass, and biomass allocation, and for most traits the impacts varied significantly in direction and/or magnitude across S. alterniflora genotypes. These results suggest that trait variation previously attributed to environmental conditions in salt marshes may also be influenced by genotype‐specific responses to fungal associates, with important implications for habitat restoration and climate adaptation planning.

根系相关真菌为宿主提供了一系列功能，并且可以强烈影响植物的结构和生理特性。需要更好地了解植物-真菌关系中的种内变异，尤其是在具有高度生态重要性的非模型系统中，这些相互作用可能会影响群落和生态系统过程。休斯等。进行了一项普通的花园接种实验，以测试一种海洋深色隔生内生真菌（Lulwoana sp。）对寄主盐沼植物互花米草互花米草不同基因型性状的影响。Lulwoana影响互花米草形态，生物量和生物量分配，并且对于大多数性状，互花链球菌基因型的影响在方向和/或大小上有很大差异。这些结果表明，以前归因于盐沼环境条件的性状变异也可能受到对真菌伴的基因型特异性反应的影响，这对栖息地的恢复和气候适应规划具有重要意义。
