摘　　要：Dear Editor,Perennial ryegrass (Lolium perenne) is a globally important forage and turf grass species that commonly forms symbiotic associations with the asexual fungal endophyte—Epichloe festucae var.lolii.Epichloe endophytes mutualistically interact with host plants by providing major fitness enhancements and protection from both biotic and abiotic stresses (Young et al.,2013).Previous studies have shown that Epichloe festucae var.lolii inhibits the growth of plant pathogenic fungi and fungal spore germination in vitro.Additional studies conducted in the lab or field confirmed that endophytes inhibited pathogen invasion and lesion development in perennial ryegrass.However,endophytes are not always beneficial,and may even weaken the host plant and reduce the disease resistance of the host.Such inconsistent or contrasting results in Festuca spp.,Achnatherum inebrians and Leymus chinensis have also been reported (Wang et al.,2016).
