摘　　要：Dear Editor,Achnatherum inebrians,also known as drunken horse grass（DHG）,is a toxic perennial bunch grass that can be infected by Epichloegansuensis or E.inebrians（Chen et al.,2015）.It is well known that Epichloefungal endophytes can protect their host plants from herbivores by producing different classes of alkaloids.A recent trial demonstrated that sheep exhibited notable toxicity symptoms by directly feeding with endophyte-infected（E＋）A.inebrians（Liang et al.,2017）.Dear Editor,Achnatherum inebrians,also known as drunken horse grass(DHG),is a toxic perennial bunch grass that can be infected by Epichlo?gansuensis or E.inebrians(Chen et al.,2015).It is well known that Epichlo?fungal endophytes can protect their host plants from herbivores by producing different classes of alkaloids.A recent trial demonstrated that sheep exhibited notable toxicity symptoms by directly feeding with endophyte-infected(E+)A.inebrians(Liang et al.,2017).
