Plants host numerous endophytic microbes which promote plant performance, in particular under stress. A new endophytic fungus was isolated from the leaves of a deciduous wood tree Morphological inspection and multilocus phylogeny identified the fungus as a new strain. If applied to and , it mainly colonizes their roots and strongly promotes initial growth of the plants on soil. The fungus grows on high NaCl or mannitol concentrations, and shows predatory capability on the pathogenic fungus . Colonized plants tolerate higher salt stress and show lower spread in roots and shoots, while arbuscular mycorrhiza formation in is not affected by the strain. These beneficial features of the novel strain are important prerequisites for agricultural applications.
植物体内寄生着大量内生微生物，这些微生物可促进植物生长，尤其是在胁迫条件下。从一种落叶乔木的叶片中分离出一种新的内生真菌。通过形态学检查和多位点系统发育分析确定该真菌为一个新菌株。如果将其应用于[具体植物1]和[具体植物2]，它主要定殖在它们的根部，并强烈促进植物在土壤中的初期生长。该真菌能在高浓度氯化钠或甘露醇环境中生长，并对致病真菌[具体致病真菌]表现出捕食能力。被定殖的植物能耐受更高的盐胁迫，且在根和茎中的[具体病害名称]传播率较低，而[具体植物]中丛枝菌根的形成不受该菌株影响。这种新型菌株的这些有益特性是农业应用的重要前提条件。
