摘　　要：醉马草[Achnatheruminebrians(Hance)Keng]是我国北方地区常见的多年生禾本科植物,感染Neotyphodium属内生真菌后成为醉马草内生真菌共生体,共生体植株能产生麦角类生物碱,草食家畜过量采食引起中毒。中毒牲畜出现共济失调、神情呆滞或烦躁不安等神经症状,中毒严重者可致死。由于醉马草内生真菌共生体具有较强的抗阻逆特性,因此针对其抗性机理的研究已成为国际上禾草-内生真菌共生体研究领域的重要内容。文章主要概述了醉马草危害及防控、产毒机制和开发应用研究进展。Achnatherum inebrians (Hance) Keng,Drunken horse grass is a common perennial bunchgrass in north China, it can be infected by endophytic fungi ( Neotyphodium ) and produce ergot alkaloid, which could result to serious poisoning once grass-feeding livestock overfeed.The toxic animal appeared neurological symptoms such as ataxia, sluggishness or restlessness, serious poisoning can be fatal.Due to the anti-resistance characteristics of A.inebrians , the study focus on the mechanisms of stress tolerance of A.inebrians-Epichlo sp. have been widespread concern around the world.This paper reviews the progress of the detriment, prevention, toxicity and utilization of A.inebrians .
