摘　　要：大麦属(Hordeum)植物多作为优良牧草和粮食作物被人类利用。禾草内生真菌(Epichlo?属)是生活周期全部或者大部分在宿主体内完成,不使宿主产生外部症状的一类真菌。禾草内生真菌可以改善宿主应对生物胁迫和非生物胁迫的能力。研究大麦属内生真菌共生体,对于开发耐盐碱的牧草或者草坪草新品种具有重要意义。本文简述了国内外大麦属禾草内生真菌共生体在侵染率影响因子、鉴定和抗逆性等方面的研究进展,认为关于大麦属内生真菌共生体的研究中影响带菌率和生物碱含量高低的因素尚不明确,对于大麦属内生真菌共生体的利用亦不充分。希望能够通过本文为大麦属内生真菌共生体的后续研究及利用提供指导。Most plants of the genus Hordeum form excellent pastures and are important food crops.It is well known that endophytic fungi live inside the plant.In this paper,all endophytic fungi belonging to the genus Epichlo?were investigated.Endophytes inhabit above-ground plant tissues without causing disease symptoms.They can improve the host's ability to deal with biotic stress and abiotic stress.It is of great ecological and economic value to study the endophytic fungi symbionts of Hordeum.This article reviews the research progress in the study of the symbiotic endophytic fungi in Hordeum plants in China and abroad.It is believed that the reasons affecting the content of alkaloids and rate of infection are not clear,and the utilization of symbiosis is not sufficient.This paper aims to provide guidance for the research and utilization of the symbiosis for the future.
